【Abstract】 TiO₂ photocatalytic coating is a kind of ideal environmental protection function coating which has photocatalytic degradation of environmental pollutants in gaseous state environment. Through element doping in TiO₂,the charge separation efficiency of composite catalyst system of TiO₂ can be improved and the absorption range of TiO₂ for visible light can be further extended,resulting into the improvement of the photocatalytic activity. In this paper,the latest application research progress of TiO₂ doped with one element and co-doped with two elements in the field of environmental protection function coating at home and abroad in recent years was reviewed. Besides,the main problems and the future striving directions in the doping and modification of TiO₂ photocatalytic coating were presented.更多还原
