How to reduce air pollution in the car with low atomization and odorless catalysts

Introduction

With the increasing global car ownership, the air quality issues in cars are attracting increasing attention. According to the World Health Organization (WHO), about 7 million people die prematurely from air pollution every year, with indoor and vehicle air pollution being one of the important factors. Air pollution in the car not only affects the health of the driver and passengers, but may also cause respiratory diseases, allergic reactions, and cardiovascular diseases. Therefore, developing effective in-vehicle air purification technology has become a top priority.

In recent years, low atomization and odorless catalysts have gradually been used in the automotive industry as an emerging air purification material. Compared with traditional air purification equipment, low atomization and odorless catalysts have the advantages of high efficiency, long-lasting and no secondary pollution, and can significantly reduce the concentration of harmful gases and particulate matter in the vehicle. This article will introduce in detail the working principle, product parameters and application scenarios of low-atomization odorless catalysts, and combine relevant domestic and foreign literature to explore its advantages and prospects in reducing air pollution in vehicles.

The main source of air pollution in the car

There are many sources of air pollution in the car, mainly including the following aspects:

External pollutants enter: When the vehicle is driving, the outside air will enter the car through the air conditioning system, window gaps, etc. These external pollutants include PM2.5, PM10, nitrogen dioxide (NO₂), carbon monoxide (CO), volatile organic compounds (VOCs), etc. Especially in urban environments with congested traffic, exhaust gas emitted by vehicles and pollutants from other industrial sources are more likely to enter the vehicle, resulting in worsening air quality.
Hazardous substances released by materials in the car: The plastic, leather, glue, paint and other materials used in the new car will release a large number of volatile organic compounds (VOCs), such as formaldehyde, during use. , , A, 2 A, etc. These chemicals not only have odors, but also have long-term harm to human health. Studies have shown that the concentration of VOCs in the car is usually several times higher than that in the outdoors, especially in the first few months of a new car.
Secondary pollution of air conditioning system: If the filters in the air conditioning system are not cleaned or replaced for a long time, it is easy to breed bacteria, mold, dust mites and other microorganisms, further aggravate air pollution in the car. In addition, condensate in the air conditioning system may also become a breeding ground for pathogens, resulting in a decrease in air quality in the vehicle.
Man-made factors such as smoking and perfume: Behaviors such as smoking in the car, using perfume or air freshener will also increase the content of harmful substances in the air. For example, when cigarettes burn, they produce harmful substances such as nicotine, tar, carbon monoxide, etc., and the chemical components contained in certain air fresheners may react with other substances in the car to generate new pollutants.
Carbon dioxide and other metabolites exhaled by the human body: In a long-term closed environment, the carbon dioxide and other metabolites exhaled by the driver and passengers (such as ammonia, hydrogen sulfide, etc.) will be in the air in the air in a long-term closed environment. accumulates in the process, resulting in a decrease in air quality. This is more obvious, especially when multiple people ride.

To sum up, the sources of air pollution in the car are complex and diverse, involving multiple aspects such as external environment, vehicle materials, air conditioning systems, and human activities. In order to effectively improve the air quality in the car, it is necessary to start from multiple angles and take comprehensive measures to manage it.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is a new air purification material based on nanotechnology and catalytic reactions. Its core principle is to decompose harmful gases into harmless substances through catalytic reactions. Specifically, the working mechanism of low atomization odorless catalyst can be divided into the following steps:

1. Adsorption

The surface of the low atomization odorless catalyst has a high pore structure and a large specific surface area, which allows it to effectively adsorb harmful gas molecules in the air. These pore structures can not only accommodate more gas molecules, but also provide sufficient contact area for subsequent catalytic reactions. Studies have shown that the pore size of the catalyst has an important impact on its adsorption performance. Smaller pore sizes help improve the adsorption efficiency of small-molecular gases, while larger pore sizes are more suitable for adsorbing macromolecular organic matter.

2. Catalytic reaction

Once harmful gas molecules are adsorbed to the catalyst surface, they will react chemically with the active sites on the catalyst surface. Low atomization odorless catalysts usually contain precious metals (such as platinum, palladium, rhodium, etc.) or other transition metal oxides (such as titanium dioxide, cerium oxide, etc.). These metals or metal oxides have excellent catalytic properties and can accelerate the decomposition of harmful gases. reaction. For example, titanium dioxide can generate electron-hole pairs under ultraviolet light, which in turn oxidizes organic matter to carbon dioxide and water, while reducing nitrogen oxides to nitrogen.

3. Release of decomposition products

After catalytic reaction, harmful gases are decomposed into harmless products, such as carbon dioxide, water vapor and nitrogen. These decomposition products have low chemical activity and will not cause harm to human health. Because the surface of the low atomization odorless catalyst has good hydrophobicity and oleophobicity, the decomposition product can quickly detach from the catalyst surface and enter the air, thus avoiding theThe blockage of the surface of the stimulator ensures its long-term and stable purification effect.

4. No secondary pollution

Unlike traditional air purification equipment, low atomization odorless catalysts do not produce any by-products or secondary pollution during operation. Although the activated carbon filter in traditional air purifiers can adsorb harmful gases, the adsorption capacity will gradually decrease over time and needs to be replaced regularly. Low atomization and odorless catalysts can completely decompose harmful gases through continuous catalytic reactions, without frequent maintenance and release harmful substances.

5. Low atomization characteristics

Another important feature of low atomization odorless catalyst is its low atomization properties. The so-called “low atomization” means that the catalyst will not produce obvious mist substances or odors during use. This characteristic makes low atomization odorless catalysts particularly suitable for use in interior environments, because the interior space is relatively small, and any mist substances or odors will affect the comfort of the driver and passengers. Studies have shown that the atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than the atomization rate of traditional catalysts (1%-5%), so it can achieve high efficiency without affecting the air quality in the car. air purification.

Product parameters of low atomization odorless catalyst

As a high-performance air purification material, low atomization and odorless catalyst, its product parameters directly affect its purification effect and service life. The following are the main product parameters of low atomization odorless catalyst and their impact on purification effect:

parameter name	Unit	Typical	Impact

Chemical Stability	–	High	It is not easy to react with other substances and avoid secondary pollution
Service life	year	3-5	The longer the service life, the lower the maintenance cost

1. Specific surface area

Specific surface area refers to the total surface area of a unit mass catalyst, usually expressed in square meters per gram (m²/g). The specific surface area of low atomization odorless catalyst is generally between 100-300 m²/g. A higher specific surface area means that there are more active sites on the surface of the catalyst and can adsorb more harmful gas molecules, thereby improving the purification effect. Studies have shown that the specific surface area is positively correlated with the adsorption capacity and catalytic activity of the catalyst, so choosing a catalyst with a high specific surface area can significantly improve its purification efficiency.

2. Pore size distribution

Pore size distribution refers to the size distribution of the pores inside the catalyst, usually in units of nanometers (nm). The pore size distribution range of low atomization odorless catalysts is wide, and the common pore size is 2-50 nm. Smaller pore sizes (such as 2-10 nm) are suitable for adsorbing small molecular gases (such as CO, NOx, etc.), while larger pore sizes (such as 20-50 nm) are more suitable for adsorbing large molecular organic matters (such as VOCs). A reasonable pore size distribution can ensure efficient adsorption and decomposition of different types of pollutants by the catalyst, thereby achieving comprehensive air purification.

3. Catalyst activity

Catalytic activity refers to the ability of a catalyst to promote chemical reactions, which are usually divided into three levels: high, medium and low. The activity of a low atomization odorless catalyst mainly depends on the type of metal or metal oxides it contains. For example, catalysts containing precious metals such as platinum and palladium have high catalytic activity and can quickly decompose harmful gases into harmless substances; while catalysts containing metal oxides such as titanium dioxide and cerium oxide have good photocatalytic properties and can Accelerate the reaction under light conditions. Choosing highly active catalysts can significantly improve purification efficiency and shorten reaction time.

4. Atomization rate

Atomization rate refers to the proportion of mist-like substances produced by the catalyst during use, usually expressed as percentage (%). The atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than that of conventional catalysts (1%-5%). Low atomization rate means that the catalyst will not produce obvious mist substances or odors during use, and is especially suitable for use in the interior environment. Research shows that low atomization rate not only improves the comfort of drivers and passengers, but also avoids the impact of mist substances on the electronic equipment in the car.

5. Hydrophobic and oleophobic

Hydrophobicity and oleophobicity refer toThe repulsion ability of the surface of the �� The low-atomization odorless catalyst has good hydrophobicity and oleophobicity, which can effectively prevent moisture and oil substances from adhering to their surface, thereby maintaining the cleanliness and activity of the catalyst. Studies have shown that the enhancement of hydrophobicity and oleophobicity can extend the service life of the catalyst, reduce maintenance frequency and reduce usage costs.

6. Temperature stability and chemical stability

Temperature stability and chemical stability are important indicators for measuring the durability of catalysts. Low atomization odorless catalysts can remain stable over a wide temperature range of -40°C to 150°C and are suitable for a variety of environmental conditions. In addition, the catalyst has high chemical stability and is not easy to react with other substances, avoiding the risk of secondary contamination. Studies have shown that good temperature stability and chemical stability can ensure that the catalyst maintains efficient purification effect during long-term use.

7. Service life

Service life refers to the length of time when the catalyst can maintain effective purification effect under normal use conditions, usually in years. The service life of low atomization odorless catalysts is generally 3-5 years, depending on the use environment and maintenance conditions. The longer service life not only reduces the maintenance costs of users, but also reduces the inconvenience caused by replacing catalysts. Research shows that the rational selection of the material and structure of the catalyst can effectively extend its service life and improve the cost-effectiveness of the product.

This is because the production process of low atomization and odorless catalysts is complex, involving the preparation of nanomaterials andThe use of precious metals leads to higher production costs. This may be a limiting factor for some price-sensitive users.
Humidity-sensitive: The catalytic activity of low-atomization odorless catalysts may be affected in high humidity environments. Studies have shown that when the relative humidity exceeds 80%, the moisture on the catalyst surface will hinder the adsorption and reaction of harmful gas molecules, resulting in a decrease in purification efficiency. Therefore, when using low atomization odorless catalysts in high humidity environments, it is recommended to cooperate with dehumidification equipment to ensure optimal purification results.
Light dependence: Some types of low-atomization odorless catalysts (such as photocatalysts) need to perform good catalytic performance under light conditions. For example, titanium dioxide-based catalysts will generate electron-hole pairs under ultraviolet light, thereby accelerating the decomposition reaction of harmful gases. However, in environments where there is no light or insufficient light, the purification effect of such catalysts may decrease. Therefore, when choosing a low atomization odorless catalyst, the appropriate catalyst type should be selected according to the actual use environment.
Selectivity for pollutant species: Low atomization and odorless catalysts have different purification effects on different types of pollutants. Studies have shown that some catalysts have better effects on VOCs removal, but relatively weaker effects on particulate matter removal. Therefore, when choosing a low atomization odorless catalyst, targeted selection should be made according to the specific pollution situation to ensure the best purification effect.
