Photocatalysis is the use of TiO₂ as a catalyst for the photocatalytic process, mild reaction conditions, rapid photolysis products of CO₂ and H₂O, etc., suitable for a wide range, including hydrocarbons, alcohols, aldehydes, ketones, ammonia and other organic matter, can through the TiO₂ photocatalytic degradation. The mechanism is mainly under the irradiation of ultraviolet light photocatalyst titanium dioxide absorbs a photon, hydroxyl radical reaction with water surface (OH) and reactive oxygen species (O, H₂O₂), the hydroxyl radical (- OH) is one of the main active substance of photocatalytic reaction, effect on Photocatalytic oxidation. The hydroxyl radical has high reaction energy, higher than all kinds of chemical bonds in most organic compounds, which can quickly and effectively decomposition of volatile organic compounds (VOC) and the composition of bacterial organic matter, plus other reactive oxygen species (O, H₂O₂) the synergistic effect of the sterilization effect more quickly.

1 high purification efficiency, its strong oxidation can be completely removed VOC, inorganic compounds, sulfide, etc., as well as the stench of gas will be non odorous gas, no two pollution;

2 photocatalytic oxidation can be suitable for a variety of occasions, different air volume and different concentrations of the smell of harmful gases, continuous operation, stable and reliable;

3 low operating costs, no consumables, unattended, the operating cost is only power consumption;

4: the broad spectrum of photocatalytic oxidation is effective for hydrocarbons to hydroxy acids from many types of organic matter, even for atomic organic compounds such as chlorinated hydrocarbons, dyes, organic nitrogen, organic phosphorus pesticides also have very good removal effect, after a certain time of reaction can be achieved complete purification;

5 long life: in theory, the life of the photocatalyst is infinitely long, no need to replace the light source used in the name of more than 50000 hours;
 

   Ammonia and trimethylamine, hydrogen sulfide, dimethyl sulfide hydrogen, methyl mercaptan and dimethyl sulfide, butyl acetate, ethyl acetate, two methyl two sulfur, carbon disulfide and styrene sulfide, H2S, molecular chain structure of VOC, benzene, toluene and xylene.
 

   Petroleum and petrochemical, rubber tire, sewage station, waste treatment, medical chemical, food production, printing coating, paint spraying and other industries.
