Mechanism Research Progress on Modification of Nonmetal Doping TiO_2 Photocatalyst

Based on the research of TiO2 photocatalyst,the study in modification of TiO2 photocatalyst included the study in metal doping,nobel metal sediment,dye photosensitization,composite semiconductors,nonmetal doping.The nonmetal doping was better than other ways,but the mechanism study in nonmetal doping was not enough.The mechanism research of nonmetal doping TiO2 photocatalyst was described systematically.
