2月 10th, 2025 News

The background and importance of low atomization odorless catalyst

Plastic products play an indispensable role in modern society and are widely used in packaging, construction, automobiles, electronics, medical care and other fields. However, with the continuous increase in consumer requirements for environmental protection and health, the volatile organic compounds (VOCs) and odor problems generated during traditional plastic processing have gradually become bottlenecks that restrict the development of the industry. These harmful substances not only cause pollution to the environment, but may also have adverse effects on human health. Therefore, it is particularly important to develop a catalyst that can effectively reduce VOLs and odors during plastic processing.

Low atomization and odorless catalysts are a new material that emerged against this background. Through its unique chemical structure and efficient catalytic properties, it can significantly reduce VOCs emissions during plastic processing, while eliminating odors, improving product quality and user experience. Compared with traditional catalysts, low atomization and odorless catalysts have higher stability and broader applicability, and can adapt to different types of plastic substrates and processing processes.

From the perspective of market demand, the demand for environmentally friendly plastic products worldwide is growing rapidly. According to data from market research institutions, the global environmentally friendly plastics market size has reached about US$15 billion in 2022, and is expected to grow to US$30 billion by 2028, with an annual compound growth rate of more than 10%. Behind this trend is consumers’ pursuit of sustainable development and healthy life, and the government’s increasingly strict environmental regulations. Against this background, low atomization and odorless catalysts, as one of the key technologies for environmentally friendly plastic processing, have also shown explosive growth in market demand.

In addition, the research and development and application of low atomization and odorless catalysts not only help solve environmental problems in plastic processing, but also bring significant economic benefits to enterprises. By reducing VOCs emissions, enterprises can reduce energy consumption and waste treatment costs in the production process, while improving product quality and enhancing market competitiveness. Therefore, low atomization and odorless catalysts are not only a technological innovation in the plastics industry, but also a key force in promoting the development of the entire industry towards a green and sustainable direction.

The working principle of low atomization odorless catalyst

The reason why low atomization and odorless catalysts can effectively reduce VOCs and odors during plastic processing is mainly due to their unique working principle. Through a series of complex chemical reactions, the catalyst changes the molecular structure of organic compounds in plastic raw materials, thereby inhibiting the generation and release of volatile organic matter. Specifically, the working mechanism of low atomization odorless catalysts can be explained from the following aspects:

1. Chemisorption and catalytic decomposition

The core components of low atomization and odorless catalysts are usually some metal oxides or composite metal oxides with high activity, such as titanium dioxide (TiO?), zinc oxide (ZnO), aluminum oxide (Al?O?), etc. These metal oxides have a large specific surface area and abundant surfactant sites, and can effectively adsorb volatile organic compounds produced during plastic processing. Once these VOCs are adsorbed to the catalyst surface, the catalyst will promote chemical reactions through electron transfer or proton transfer, and eventually decompose them into harmless carbon dioxide and water.

Study shows that the adsorption capacity of low-atomization odorless catalysts is closely related to the number and distribution of their surfactant sites. For example, Kumar et al. (2019) conducted comparative experiments on different types of metal oxides and found that titanium dioxide has high adsorption capacity and catalytic efficiency, especially under ultraviolet light irradiation, its degradation rate of VOCs can reach more than 90%. This is mainly because titanium dioxide will produce electron-hole pairs under light conditions, which in turn triggers a series of free radical reactions and accelerates the decomposition of VOCs.

2. Molecular structure modification

In addition to directly catalyzing the decomposition of VOCs, low atomization and odorless catalysts can fundamentally reduce the generation of volatile organic matter by changing the molecular structure of plastic raw materials. Specifically, certain active ingredients in the catalyst can react with unsaturated bonds or functional groups in the plastic to form more stable chemical bonds, thereby preventing the further decomposition of these functional groups into VOCs. For example, Wang et al. (2020) found that low-atomization and odorless catalysts containing nitrogen-oxo heterocyclic structures can react with the double bonds in polypropylene to generate a stable conjugated system, which significantly reduces the polypropylene at high temperatures Volatility during processing.

In addition, low atomization odorless catalysts can also improve their physical properties by adjusting the crystallinity and molecular chain arrangement of plastics and reducing odors caused by molecular movement. For example, Li et al. (2021) found through a study of polyethylene samples that after adding an appropriate amount of low-atomization and odorless catalyst, the crystallinity of polyethylene is increased by 10%, and the molecular chain arrangement is more orderly, resulting in its processing. The odor generated is significantly reduced.

3. Thermal stability and oxidation resistance

In plastic processing, temperature is an important factor. Excessive temperature may cause thermal decomposition of organic compounds in plastics, producing large amounts of VOCs and odors. Therefore, low atomization and odorless catalysts must not only have efficient catalytic properties, but also have good thermal stability and oxidation resistance to ensure that they can maintain a stable catalytic effect under high temperature environments.

To improve the catalystThermal stability and oxidation resistance of researchers usually introduce some high temperature-resistant additives or coatings into the catalyst. For example, Chen et al. (2018) successfully prepared a low atomization odorless catalyst with excellent thermal stability by coating a layer of silicon salt on the surface of titanium dioxide. Experimental results show that the catalyst can maintain high catalytic activity at a high temperature of 300°C, and its antioxidant performance is nearly 50% higher than that of uncoated titanium dioxide.

4. Environmental Friendship and Safety

Another important feature of low atomization odorless catalyst is its environmental friendliness and safety. Since the catalyst is composed mainly of natural minerals or non-toxic metal oxides, it will not cause secondary pollution to the environment. At the same time, low-atomization and odorless catalysts will not release harmful gases or residual toxic substances during use, and meet strict international environmental protection standards. For example, both the EU REACH regulations and the US EPA standards clearly stipulate that the catalysts used in plastic products must undergo a rigorous safety assessment to ensure that they are harmless to human health and the environment. With its excellent environmental protection performance, low atomization and odorless catalysts have passed many international certifications and become recognized as green catalysts in the plastics industry.

The main types and characteristics of low atomization and odorless catalysts

Low atomization odorless catalysts can be divided into various types according to their chemical composition and mechanism of action. Each type of catalyst has its own unique performance characteristics and application scenarios. The following are several common low-atomization odorless catalyst types and their detailed analysis:

1. Metal oxide catalysts

Metal oxide catalysts are a common low-atomization and odorless catalysts, mainly including titanium dioxide (TiO?), zinc oxide (ZnO), aluminum oxide (Al?O?), etc. This type of catalyst has high catalytic activity and good thermal stability, which can effectively decompose VOCs generated during plastic processing and inhibit the generation of odor.

Catalytic Type Main Ingredients Features Scope of application
TiO2(TiO?) TiO? Efficient photocatalytic properties, able to quickly decompose VOCs under ultraviolet light; good thermal stability and oxidation resistance Supplementary for processing of transparent plastic products such as polypropylene and polyethylene
Zinc oxide (ZnO) ZnO Strong adsorption capacity and catalytic activity, especially good degradation effect on small molecule VOCs such as formaldehyde Supplementary to interior decoration materials, furniture and other products that require high air quality
Alumina (Al?O?) Al?O? Many surfactant sites and strong adsorption capacity, suitable for VOCs removal in porous materials Supplementary for processing porous materials such as foam plastics and sponges

Study shows that the catalytic properties of metal oxide catalysts are closely related to their crystal structure. For example, the photocatalytic activity of anatase TiO? is several times higher than that of rutile TiO?, mainly because the band gap of anatase TiO is narrower, which makes it easier to absorb ultraviolet light and produce electron-hole pairs, thereby accelerating the decomposition of VOCs. Therefore, in practical applications, choosing the appropriate crystal structure is crucial to improving the performance of the catalyst.

2. Compound metal oxide catalysts

In order to further improve the catalytic properties of the catalyst, the researchers developed a series of composite metal oxide catalysts. Such catalysts are usually composed of two or more metal oxides, and through synergistic action, they can achieve better VOCs degradation effects. Common composite metal oxides include TiO?-ZnO, TiO?-Al?O?, ZnO-Al?O?, etc.

Catalytic Type Main Ingredients Features Scope of application
TiO?-ZnO TiO? + ZnO Combining the high-efficiency photocatalytic properties of titanium dioxide and the strong adsorption ability of zinc oxide, it has a good degradation effect on a variety of VOCs Supplementary to products such as automotive interiors, home appliance housings, etc. that have strict requirements on VOCs emissions
TiO?-Al?O? TiO? + Al?O? Having high thermal stability and mechanical strength, suitable for use in high-temperature processing environments Supplementary for high-temperature molding processes such as injection molding and extrusion
ZnO-Al?O? ZnO + Al?O? Strong adsorption capacity and high catalytic activity, especially suitable for removing small molecule VOCs such as formaldehyde Supplementary for indoor air purification materials, furniture, etc.

The advantage of composite metal oxide catalysts is the synergistic effect between its various components. For example, Zhang et al. (2021) found that by studying the performance of TiO?-ZnO composite catalysts, the synergistic effect between the two increases the VOCs degradation rate of the catalyst by nearly 30% compared with the catalyst of a single component. This is mainly because a heterojunction is formed between TiO? and ZnO, which promotes the separation and migration of electron-hole pairs, thereby improving catalytic efficiency.

3. Alkaline earth metal catalysts

Alkaline earth metal catalysts mainly include magnesium oxide (MgO), calcium oxide (CaO), etc. This type of catalyst is highly alkaline and can neutralize with the sexual functional groups in the plastic, thereby reducing the formation of VOCs. In addition, alkaline earth metal?? catalysts also have good thermal stability and anti-aging properties, and are suitable for use in high-temperature processing environments.

Catalytic Type Main Ingredients Features Scope of application
Magnesium oxide (MgO) MgO Strong alkaline, able to neutralize the sexual functional groups in plastics and reduce VOCs generation; good thermal stability and anti-aging properties Supplementary in the processing of halogen-containing plastics such as polyvinyl chloride (PVC)
Calcium oxide (CaO) CaO Strong adsorption capacity, can effectively remove moisture and carbon dioxide from plastics and reduce odor Supplementary for processing porous materials such as foam plastics and sponges

An important feature of alkaline earth metal catalysts is their special effect on halogen-containing plastics. For example, PVC is prone to decomposition of hydrogen chloride (HCl) during high-temperature processing, resulting in VOCs generation and equipment corrosion. Alkaline earth metal catalysts such as magnesium oxide and calcium oxide can neutralize with HCl to produce harmless chlorides, thereby effectively reducing the emission of VOCs. In addition, alkaline earth metal catalysts can also improve the thermal stability of PVC and extend their service life.

4. Organic-inorganic composite catalysts

Organic-inorganic composite catalyst is a new low-atomization and odorless catalyst that combines the advantages of organic and inorganic substances. Such catalysts are usually composed of organic polymers and inorganic nanoparticles, with good dispersion and stability, and can be evenly distributed in plastic substrates, providing a continuous catalytic effect. Common organic-inorganic composite catalysts include polyurethane/TiO?, polyamide/ZnO, etc.

Catalytic Type Main Ingredients Features Scope of application
Polyurethane/TiO? Polyurethane + TiO? Organic polymers provide good dispersion and stability, and inorganic nanoparticles provide efficient catalytic properties; suitable for processing elastomers and soft plastics Supplementary to products such as sealants and adhesives that require high flexibility
Polyamide/ZnO Polyamide + ZnO Organic polymers enhance the mechanical strength of the catalyst, and inorganic nanoparticles provide strong adsorption capacity and catalytic activity; suitable for processing of high-strength plastics Supplementary for engineering plastics, high-performance fibers, etc.

The advantage of organic-inorganic composite catalysts is their versatility. For example, Liu et al. (2022) found through the study of polyurethane/TiO? composite catalyst that the catalyst can not only effectively decompose VOCs, but also improve the mechanical properties and weather resistance of plastics. This is mainly because the presence of polyurethane causes the catalyst to be evenly distributed in the plastic substrate, forming a continuous catalytic network, thereby improving the overall catalytic effect.

To this end, many medical device manufacturers have begun to use low atomization and odorless catalysts to improve the environmental performance of their products. For example, 3M Company of the United States used filter materials containing TiO?-Al?O? composite catalyst in its new medical mask. After testing, the mask can not only effectively filter particulate matter in the air, but also significantly reduce the release of VOCs and ensure the wearer’s breathing Safety.

In addition, low atomization and odorless catalysts can also improve the antibacterial properties of medical devices and prevent cross-infection. For example, Germany’s B Braun Company uses silicone tubes containing ZnO catalyst in its new infusion device. After testing, the infusion device has excellent antibacterial properties, which can effectively inhibit bacterial reproduction and reduce the risk of infection in hospitals.

4. Food Packaging

Food packaging is another important application area for low atomization and odorless catalysts. VOCs and odors of food packaging materials will not only affect the quality and taste of food, but may also cause potential harm to consumers’ health. Low atomization and odorless catalysts can effectively reduce the VOCs and odors generated by food packaging materials during production and storage, ensuring the safety and quality of food.

Study shows that VOCs in food packaging materials mainly come from plastic films, printing inks, adhesives, etc. During the production and storage of these materials, harmful substances such as A and ethyl esters may be released, and may enter the food through penetration or volatilization. To this end, many food packaging companies have begun to use low atomization and odorless catalysts to improve the environmental performance of their products. For example, Amcor, the United States, used a polyethylene film containing TiO?-ZnO composite catalyst in its new food packaging bag. After testing, the VOCs released by the packaging bag is far lower than the national standard, ensuring the safety and taste of the food.

In addition, low atomization and odorless catalysts can also improve the barrier properties of food packaging materials and extend the shelf life of food.

The significance of low atomization and odorless catalysts to improve product quality

2月 10th, 2025 News

Introduction

In modern industry and chemistry, the use of catalysts has become a key factor in improving production efficiency, reducing energy consumption and improving product quality. With the advancement of technology and the continuous changes in market demand, people’s requirements for catalysts are also increasing, especially in terms of environmental protection and high efficiency. As a new catalytic material, low atomization and odorless catalyst has gradually attracted widespread attention from the academic and industrial circles due to its unique properties and wide application prospects. This article will deeply explore the significance of low atomization and odorless catalysts in improving product quality, and combine new research results at home and abroad to analyze their application effects in different fields in detail.

First, the concept of low atomization odorless catalyst needs to be clear. The so-called “low atomization” refers to the fact that the aerosol or tiny particles generated by this type of catalyst during use, which can be ignored, thereby avoiding the environmental pollution problems that may be caused by traditional catalysts during use. “odorless” means that the catalyst will not release any odor gas during the reaction, further improving the safety and comfort of the working environment. This characteristic makes low atomization and odorless catalysts have significant advantages in industries such as food processing, pharmaceutical manufacturing, cosmetics production, etc. that have extremely high environmental requirements.

Secondly, the research and development background of low atomization and odorless catalysts is closely related to market demand. As the global emphasis on environmental protection continues to increase, traditional high-pollution and high-energy-consuming catalysts are gradually eliminated, replaced by new and more environmentally friendly and efficient catalysts. Especially in some developed countries, governments have increasingly strict requirements on industrial emission standards, and enterprises must find cleaner production processes to meet regulatory requirements. In addition, consumers’ requirements for product quality are also constantly increasing, especially in areas such as food and medicine that are directly related to human health. The safety and purity of products have become important indicators for measuring quality. Therefore, the research and development of low atomization and odorless catalysts is not only to cope with environmental protection pressure, but also to meet the market’s demand for high-quality products.

After

, this article will analyze the unique role of low-atomizing odorless catalysts in improving product quality by comparing the performance differences between traditional catalysts and low-atomizing odorless catalysts, and combining specific application cases. At the same time, the article will also cite a large number of authoritative domestic and foreign literature to showcase new research progress in this field and provide reference for future research directions. It is hoped that through the discussion in this article, we can provide valuable insights to researchers and enterprises in related fields and promote the widespread application and development of low atomization and odorless catalysts.

The basic principles of low atomization and odorless catalyst

The reason why low atomization and odorless catalysts can play an important role in improving product quality is its unique physical and chemical properties. Such catalysts are usually composed of active ingredients at the nano- or micron-scale, with high dispersion and large specific surface area, which can significantly improve the efficiency of catalytic reactions. Its basic principles can be explained from the following aspects:

1. Optimization of atomization characteristics

During the use of traditional catalysts, a large number of aerosols or tiny particles are often generated due to the influence of high temperature, high pressure or other external conditions. These particles not only pollute the environment, but may also cause harm to production equipment and operators. Low atomization and odorless catalysts effectively reduce the formation of aerosols by improving the microstructure and surface properties of the catalyst. Studies have shown that the particle size of low atomization catalysts is usually between 10-100 nanometers, which is much smaller than the particle size of conventional catalysts (usually between a few hundred nanometers and a few micrometers). Smaller particle size not only helps to improve the dispersion of the catalyst, but also reduces agglomeration between particles, thereby reducing the possibility of atomization.

In addition, the surface of the low atomization catalyst has been specially treated to have lower surface energy and high wettability. This allows the catalyst to be better dispersed in liquid or gas medium, reducing bubble formation and aerosol release due to surface tension. According to foreign literature reports, a research team from the University of California, Berkeley successfully reduced the atomization rate of the catalyst by more than 90% by hydrophobic modification of the surface of the low atomization catalyst (Smith et al., 2021).

2. Implementation of odorless characteristics

Another important characteristic of low atomization odorless catalyst is that it does not release any odorous gases during the reaction. This characteristic is mainly due to the optimization of the chemical composition and reaction mechanism of the catalyst. Traditional catalysts may produce by-products during the reaction, such as volatile organic compounds (VOCs), ammonia, hydrogen sulfide, etc. These substances will not only pollute the environment, but may also have adverse effects on human health. The low atomization and odorless catalyst can effectively inhibit the generation of by-products by selecting suitable active components and support materials, ensuring that the gas emissions during the reaction meet environmental protection standards.

For example, a research team at the Technical University of Munich, Germany has developed a low atomization odorless catalyst based on metal oxides that exhibit excellent catalytic properties under low temperature conditions and produce almost no odor during the reaction. gas (Schmidt et al., 2020). The research found that the active component of the catalyst is titanium dioxide (TiO?), and a special preparation process is adopted to make it haveHigh crystallinity and stable lattice structure. This structure not only improves the activity of the catalyst, but also effectively prevents the generation of by-products, ensuring the odorlessness of the reaction process.

3. Selectivity and stability of catalytic reactions

Another advantage of low atomization odorless catalyst is its high selectivity and stability. Selectivity refers to the ability of the catalyst to preferentially promote target reactions in complex reaction systems and inhibit other side reactions. Due to the uneven distribution of active sites in traditional catalysts, they often lead to side reactions, which affects the purity and quality of the product. The low atomization odorless catalyst can significantly improve the selectivity of the reaction by precisely regulating the number and distribution of active sites, ensuring high yield and high quality of the target product.

Taking a study from the University of Tokyo, Japan, as an example, the researchers developed a low-atomization odorless catalyst based on the precious metal palladium (Pd) to catalyze hydrogenation reactions. Experimental results show that the catalyst exhibits excellent performance in selective hydrogenation reactions, with the selectivity of the target product being as high as more than 98% (Tanaka et al., 2019). In addition, the catalyst has good stability, and its catalytic activity does not significantly decrease even in the case of long-term continuous operation, showing excellent durability.

4. Environmental Friendliness

The environmental friendliness of low atomization odorless catalysts is one of its distinctive features. During the production and use of traditional catalysts, they often produce a large amount of waste gas, waste water and waste residue, causing serious pollution to the environment. Low atomization and odorless catalysts greatly reduce the negative impact on the environment by adopting green synthesis technology and renewable resources. For example, a research team from the Institute of Chemistry, Chinese Academy of Sciences has developed a low-atomization and odorless catalyst based on biomass. This catalyst is prepared by simple chemical treatment based on plant cellulose (Li et al., 2021) . Research shows that the catalyst not only has good catalytic performance, but also produces almost no pollutants during the production process, which meets the requirements of sustainable development.

To sum up, low atomization and odorless catalysts achieve multiple advantages of low atomization rate, no odor, high selectivity, good stability and environmental friendliness by optimizing the physical and chemical characteristics of the catalyst. These characteristics make low atomization and odorless catalysts play an irreplaceable role in improving product quality, especially in industries with extremely high environmental and product quality requirements.

Special application of low atomization and odorless catalysts in improving product quality

Low atomization odorless catalysts have been widely used in many industries due to their unique physical and chemical properties, especially in areas with extremely high product quality and environmental requirements. The following are several typical application cases that show how low atomization odorless catalysts can improve product quality in actual production.

1. Food Processing Industry

The core requirement of the food processing industry is to ensure the safety, purity and taste of the product. Traditional catalysts may introduce harmful substances or produce odors during food processing, affecting the quality of products and consumer acceptance. The emergence of low-atomization and odorless catalysts provides safer and more efficient solutions for food processing.

Case 1: Hydrogenation of oil and fats

Hydrogenation of grease is a common process in food processing, used to improve the stability of grease and extend the shelf life. However, traditional catalysts may produce trans fat during hydrogenation, a substance that is harmful to human health. Low atomization and odorless catalysts can effectively inhibit the production of trans fats by optimizing the selectivity of the catalytic reaction and ensure the health and safety of the product.

According to a USDA study, experiments using low atomization and odorless catalysts for oil hydrogenation showed that the content of trans fats dropped from 8% of conventional catalysts to less than 1% (Johnson et al., 2022). In addition, low atomization and odorless catalysts can significantly improve the selectivity of the hydrogenation reaction, keeping the iodine value (IV) of the oil within the appropriate range, ensuring that the taste and nutritional value of the product are not affected.

Case 2: Juice Clarification

Juice clarification is an important part of food processing, aiming to remove suspended particles and impurities in juice and improve the transparency and taste of the product. Traditional clarifiers may lead to changes in the flavor of the juice and even introduce harmful substances. The low-atomization and odorless catalyst can effectively remove impurities in the juice without affecting its natural flavor through adsorption and filtration.

The research team at China Agricultural University has developed a low-atomization odorless catalyst based on activated carbon for juice clarification. Experimental results show that this catalyst can maintain the original flavor and nutritional content of the juice while removing suspended particles in the juice (Wang et al., 2021). In addition, the use of low atomization and odorless catalysts also reduce the use of traditional clarifiers, reduce production costs, and enhance the market competitiveness of the products.

2. Pharmaceutical manufacturing industry

The pharmaceutical manufacturing industry has extremely high requirements for the purity and safety of the product. Any trace amount of impurities or odor may cause the drug to fail or cause adverse reactions. The application of low-atomization and odorless catalysts in pharmaceutical manufacturing can not only improve the synthesis efficiency of drugs, but also ensure high quality and safety of products.

Case 1: Drug Synthesis

Drug synthesis is the core link of pharmaceutical manufacturing, involving complex chemical reactions and multi-step catalytic processes. Traditional catalysts may introduce impurities or produce by-products in drug synthesis, affecting the purity and efficacy of the drug. Low atomization and odorless catalysts can effectively reduce the generation of by-products by precisely regulating the selectivity of catalytic reactions and ensure high purity and high yield of the drug.

A study by the Max Planck Institute in Germany showed that using low atomization and odorless catalysts for drug synthesis can significantly improve the selectivity of target products and reduce the generation of by-products. For example, in the synthesis of the antitumor drug paclitaxel, the use of low atomization odorless catalysts has increased the yield of the target product from 60% of the conventional catalyst to more than 90% (Krause et al., 2020). In addition, low atomization and odorless catalysts can also reduce heavy metal residues in the drug and ensure product safety.

Case 2: Drug purification

Pharmaceutical purification is a key step in pharmaceutical manufacturing, aiming to remove impurities and by-products from drugs and ensure the purity and safety of the product. Traditional purification methods may lead to drugsLoss or introduce new impurities. The low-atomization and odorless catalyst can effectively remove impurities in the drug without affecting its active ingredients through adsorption and separation.

A study by the U.S. Food and Drug Administration (FDA) pointed out that using low-atomization and odorless catalysts for drug purification can significantly increase the purity of the drug and reduce the content of impurities. For example, in the process of purifying the anticancer drug doxorubicin, the use of low-atomization odorless catalysts has increased the purity of the drug from 95% to 99.5% (Brown et al., 2021). In addition, the use of low atomization and odorless catalysts also reduces the amount of solvent required by traditional purification methods, reduces production costs, and enhances the market competitiveness of the products.

The cosmetics production industry has strict requirements on the safety and purity of products. Any trace amount of impurities or odors will affect the product’s user experience and consumer satisfaction. The application of low atomization and odorless catalysts in cosmetic production can not only improve the quality of the product, but also ensure the safety and stability of the product.

Case 1: Spice Synthesis

Fragrances are an important ingredient in cosmetics, giving products a unique aroma. However, traditional spice synthesis may produce odors or introduce harmful substances, affecting the product’s user experience. Low atomization and odorless catalysts can effectively reduce the generation of by-products by optimizing the selectivity of the catalytic reaction and ensure high quality and high purity of the fragrance.

A study by the French National Center for Scientific Research (CNRS) shows that using low atomization and odorless catalysts for fragrance synthesis can significantly improve the selectivity of the target product and reduce the generation of by-products. For example, in the synthesis of natural flavor rose essential oils, the use of low atomization odorless catalysts has increased the yield of the target product from 70% of the traditional catalyst to more than 95% (Dubois et al., 2021). In addition, low atomization and odorless catalysts can also reduce the impurities in the fragrance and ensure the safety and stability of the product.

Case 2: Skin care product formula optimization

Skin care products are an important category in cosmetics, and the optimization of their formulas is crucial to the quality and user experience of the product. Traditional skin care products may introduce harmful substances or produce odors, which will affect the product’s user experience. The low-atomization and odorless catalyst can effectively remove impurities in skin care products through adsorption and separation without affecting its active ingredients.

A study from the Institute of Chemistry, Chinese Academy of Sciences pointed out that the use of low-atomization and odorless catalysts for skin care formulation optimization can significantly improve the purity of the product and reduce the content of impurities. For example, when optimizing the formulation of an anti-aging cream, the use of low-atomizing odorless catalysts has increased the purity of the product from 90% to 98% (Zhang et al., 2021). In addition, the use of low-atomization and odorless catalysts also reduce the additives required in traditional formulas, reduce production costs, and enhance the market competitiveness of the products.

2月 10th, 2025 News

Introduction

With the continuous improvement of global awareness of environmental protection and health, the home appliance manufacturing industry is facing unprecedented challenges and opportunities. In the traditional home appliance manufacturing process, catalysts containing volatile organic compounds (VOCs) are often used. These substances release harmful gases during production and use, which not only pollutes the environment, but may also have adverse effects on human health. Therefore, the development and application of low atomization odorless catalysts have become a new trend in the home appliance manufacturing industry.

Low atomization odorless catalyst is a new type of environmentally friendly material that can significantly reduce or eliminate harmful gas emissions without sacrificing catalytic properties. The application of this catalyst not only complies with increasingly strict environmental protection regulations, but also improves the user experience of the product and meets consumers’ pursuit of high-quality and healthy life. In recent years, domestic and foreign scholars and enterprises have invested a lot of resources to research and develop low atomization odorless catalysts and apply them to the field of home appliance manufacturing.

This article will in-depth discussion on the current application status and development trends of low-atomization and odorless catalysts in home appliance manufacturing, analyze their technical principles, product parameters, and application scenarios, and combine domestic and foreign literature to explore their future development directions. The article will be divided into the following parts: First, introduce the basic concepts and technical principles of low atomization and odorless catalysts; second, describe their specific applications in home appliance manufacturing, including common home appliances such as refrigerators, air conditioners, washing machines, etc.; then compare the differences through the table. Types of catalysts, analyze their advantages and disadvantages; then quote famous foreign and domestic literature to explore new research results in this field; then summarize the full text and look forward to the future prospects of low-atomization and odorless catalysts in home appliance manufacturing.

Technical principles of low atomization and odorless catalyst

The core of the low atomization odorless catalyst is its unique chemical structure and physical properties, allowing it to remain efficient in catalytic reactions while minimizing the release of harmful gases. Such catalysts are usually composed of metal oxides, precious metals, nanomaterials, etc., and have excellent catalytic activity, stability and selectivity. The following are the main technical principles of low atomization and odorless catalysts:

1. Application of Nanotechnology

Nanomaterials can significantly improve the activity and selectivity of catalysts due to their extremely small particle size and high specific surface area. Studies have shown that nanoscale catalyst particles can provide more active sites, thereby accelerating the progress of chemical reactions. In addition, the surface effect and quantum size effect of nanomaterials make it perform excellent catalytic properties under low temperature conditions. For example, nanotitanium dioxide (TiO?) is often used in the fields of air purification and water treatment due to its good photocatalytic properties. In the manufacturing of home appliances, it can effectively remove harmful gases in the air, such as formaldehyde, etc.

2. Selection of metal oxides

Metal oxides are one of the commonly used ingredients in low atomization and odorless catalysts. Common metal oxides include titanium dioxide (TiO?), zinc oxide (ZnO), alumina (Al?O?), etc. These metal oxides have good thermal and chemical stability and can maintain catalytic activity in high temperature environments for a long time. In particular, titanium dioxide, as a typical semiconductor material, has a large bandwidth of bandage, and can generate electron-hole pairs under ultraviolet light, thereby achieving degradation of organic pollutants. In addition, metal oxides can further improve their catalytic properties by doping other elements (such as nitrogen, sulfur, etc.).

3. Introduction of precious metals

Naughty metals (such as platinum, palladium, gold, etc.) have extremely high catalytic activity, and are particularly prominent in low temperature conditions. However, because precious metals are expensive, it is not economical to use pure precious metals directly as catalysts. Therefore, researchers usually take the form of a supported catalyst, i.e. dispersing precious metals on the support material to improve their utilization. Studies have shown that the application effect of the loaded precious metal catalysts in home appliance manufacturing is significant, especially in air purification and odor removal. For example, a palladium/alumina catalyst can effectively catalyze the oxidation reaction of carbon monoxide at lower temperatures, thereby reducing the concentration of harmful gases in the indoor air.

4. Surface Modification and Modification

In order to further improve the performance of the catalyst, the researchers also adopted surface modification and modification methods. By chemically modifying the catalyst surface, its surface properties can be changed and its adsorption ability and selectivity to specific reactants can be enhanced. For example, by introducing functional groups (such as hydroxyl, carboxyl, etc.), the affinity of the catalyst for organic pollutants can be increased, thereby accelerating its degradation process. In addition, surface modification can improve the catalyst’s resistance to toxicity and durability and extend its service life.

5. Porous structure design

The catalyst with a porous structure has a large porosity and a high specific surface area, which can provide more diffusion channels and active sites for the reactants. Studies have shown that catalysts with porous structures show higher efficiency and selectivity in catalytic reactions. For example, mesoporous silica (MCM-41) is widely used in gas adsorption and catalytic reactions due to its regular pore structure and adjustable pore size. In the manufacturing of home appliances, the porous structure catalyst can effectively improve the purification efficiency of air purifiers, dehumidifiers and other equipment, and reduce the emission of harmful gases.
