ABOUT PHOTOCATALYST

Photocatalyst

  • Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. A catalyst may participate in multiple chemical transformations.
  • Photocatalyst is the acceleration of a photoreaction in the presence of a catalyst. In catalyzed photolysis, light is absorbed by an adsorbed substrate.
  • We usually using photocatalyst is Titanium dioxide. It is chemically stable substance.
  • Titanium dioxide (chemical formula: TiO2) may take on any of the three crystal structures. One of them is rutile, which tends to use for a white pigment that surface covered type, beauty product and so on. Other of them is anatase, which tends to use for a photocatalyst coating materials. Another of them is brookite, which is only artifactually-produced crystal substance. It has photocatalysis effect, but it does not general use for photocatalyst coating fluid.
  • Our M-Clean series are used an anatase type and brookite type of crystal substance. The titanium dioxide of the anatase type and the brookite type generally show a higher photoactivity than the rutile type.
