Photocatalyst, also known as photocatalyst, is a kind of semiconductor materials with photocatalytic function represented by TiO2. It has a wide variety, including titanium dioxide (TiO2), zinc oxide (ZnO), tin dioxide (SnO2), zirconium dioxide (ZrO2), cadmium sulfide (CdS) and other oxides and sulfides. Nanoscale titanium dioxide will produce a certain amount of electron holes, hydroxyl free radicals and highly active negative oxygen ions under the irradiation of UV lamp in a specific band, and these substances have good sterilization and sterilization functions.The ultraviolet lamp of specific band also has certain sterilization and sterilization function;So that the use of UV lamp catalyzed nanometer titanium dioxide products with dual sterilization and sterilization capabilities. ACR light catalytic antibacterial, sterilization products is on the basis of the existing photocatalytic technology joined the specific proportion of nanoscale metal and metal oxides made different subst...
