Photocatalyst principle:

Photocatalyst is a synthetic term of light + catalyst (catalyst). As an excellent photocatalyst, nano-TiO2 with strong oxidation ability can release highly active hole / electron pairs on its surface under the action of light, and make it react with organic matters and various bacteria in the air to degrade, so as to achieve the functions of air purification, anti-bacterial and anti mildew, anti pollution and deodorization. TiO2 photocatalyst itself is close to natural substances, non-toxic and harmless. It does not participate in the reaction itself, but provides the site and conditions for the reaction, so it is permanent.

The combination of photocatalyst and visible light can enhance its activity and photocatalysis, so as to realize the use of light energy to purify air. It can decompose organic pollutants efficiently and irreversibly. It can decompose almost all bacteria, viruses and organic pollutants in the room. The sterilization rate is 99.99%, and the deodorization rate is more than 90%. A kind of Nanoscale TiO2 has excellent photocatalytic properties and has been widely applied in environmental control fields such as pollution prevention, antifouling, clean air, antibacterial disinfection, anti-aging and water purification. To improve the earth's environment, improve the quality of human living environment and solve social energy。

We have made important contributions to the issue. It has played a good role in ensuring the sustainable development of human society. TiO2 has stable performance, no energy consumption, no harm to human body and no secondary pollution to the environment. The final product is carbon dioxide and water, so it is favored in environmental protection. It is a safe and inorganic environmental protection product recognized by all countries in the world. 


1、 Function of virus killing bacteria: under the light irradiation, the photocatalyst can produce hydroxyl radical active oxygen, which has stronger oxidation ability than chlorine, hypochlorite, H202 and so on. This kind of oxidation ability destroys coenzyme A and respiratory enzymes in cells, so as to play an antibacterial role and stop the reproduction of bacteria or molds. At the same time, it coagulates the protein of the virus, inhibits the activity of the virus, and decomposes the mycotoxins released by bacteria, molds and viruses into carbon dioxide and water. It can catch and kill the floating bacteria in the air, and kill the virus by photocatalyst. The killing capacity is as high as 99.96%. It can effectively prevent and cure cross infection in hospital and antibacterial effect in public place caused by drug-resistant virus and bacteria. It can decompose the allergens in the air, reduce allergic diseases and asthma, decompose bacteria, improve the symptoms of beriberi, and do not damage the skin.

In particular, photocatalyst is a safe and effective anti-bacterial technology, which can cause cross infection and collective infection to a variety of viruses such as NCP, SARS, H5N1 and H1N1.

2、 Air purification function: decompose toxic and harmful gases in the air: benzene, formaldehyde, ammonia, H2S, TVOC, etc. The [H] and oxygen radicals produced by TiO2 will firstly destroy the energy bond of organic gas molecules, make organic gas become a single gas molecule, accelerate the decomposition of organic matter and gas, and oxidize and reduce various organic matters such as formaldehyde, benzene, nitrogen oxide, sulfur oxide and ammonia in the air into harmless substances. It can remove body odor, animal odor and smoke odor, and purify the air. When the photocatalyst is in contact with light, it can play the role of deodorant, antibacterial, antifouling and other excellent properties.

3、 Decontamination and deodorization function: decompose the oil, remove the odor of smoke and garbage, and prevent the environmental pollution caused by the two evils. Titanium dioxide TiO2 has stronger oxidation ability than ozone O3 anion, stronger adsorption than activated carbon and heap, so it has decomposition effect (bacteria decomposition) that activated carbon and heap do not have. According to the test of authoritative laboratories in Europe and America, the deodorization capacity of TiO2 with the same volume is 150 times of that of high-efficiency fiber activated carbon, which is equivalent to 500 deodorants for refrigerators. 

4、 Long term efficacy: This product is an inorganic product, and its substance will not be lost in the catalytic process, so as long as the spraying surface is not damaged, it can play a lasting role.
