Progress in Research of Doping Modification of TiO2 Photocatalyst
As a typical photocatalyst titania has been attracting much attention,the domestic and foreign modification of photocatalyst has improved steadily and had grown diversely.In this paper, the methods for doping modification of TiO2 including surface metal deposition,transition metal ions, rare earth metal ions,non -metal ion,compound semiconductor and cited some special modification application examples at home and abroad.
