Properties: photocatalyst is catalyzed by light. In some reaction systems, the reaction is not carried out or slow under the action of light or catalyst, and the reaction can be carried out quickly and completely when the light of a certain wavelength exists at the same time as the catalyst. Photocatalyst is determined by the absorptivity, charge separation and substrate transfer efficiency of the catalyst.
Use: the use of photocatalyst in sewage treatment, air cleaning, deodorization, sterilization and other aspects of the use of solar energy, COD removal rate of high, less chemicals, no two pollution and other advantages.
