| Abstract: | TiO2 nanofilm was formed by Sol-Gel method and modified on the photocatalysts by rare metal deposition such as Ag and Pt and Fe ion doping. The photocatalytic property was characterized by degrading salicylic acid and organic contaminant in reclaimed water. It's proved that TiO2 nanofilm has a good photocatalytic degradation property to the organic matters of the water. It's conformed that the technique of photo-catalytic degradation with TiO2 nanofilm would be extended widely in the future. |
