Photocatalyst Filter

The photocatalyst filter screen is made of nano-scale powder and a variety of
nano-scale light-sensitive semiconductor media for lattice doping to ensure
sufficient ventilation and contact, and then mixed with the carrier to
effectively remove airborne particles. Harmful gases and odors such as carbon
monoxide, nitrogen oxides, hydrocarbons, aldehydes, benzene, etc., can be
decomposed into harmless CO2 and H2O, and it also has a bactericidal function.
A catalyst that reacts with the participation of light. Under the illumination,
the surface of titanium dioxide forms electron holes and free electrons,
combines with water and oxygen in the air, and undergoes a redox reaction,
forming strong oxidizing hydroxyl radicals ( OH) and superoxide anion radicals
(O2ˉ) on the surface. It can decompose harmful gases and some inorganic
compounds in the air, decompose organic matter into CO2 and water, and inhibit
the growth of bacteria and the activity of viruses, so as to achieve
sterilization, air purification, deodorization and mildew prevention.
Photocatalyst can effectively purify the air, sterilize and deodorize.
The photocatalytic reaction that occurs in the presence of light will generate
hydroxyl radicals on the surface. The strong oxidative properties of hydroxyl
radicals can effectively decompose bacteria, and can decompose endotoxins
produced by bacteria after death, without any secondary pollution.
