| Abstract: | The latest research progress in improving the visible light photocatalytic activity of nano-TiO2 is reviewed. The methods for promoting the visible light photocatalytic activity include the surface chelate and derivatization, metal doping, semiconductor coupling, nonmetal doping, and dye sensitizing. The mechanisms of doping or modification by using various methods are also analyzed. In the end, the prospect of improving visible light photocatalytic activity of nano-TiO2 is proposed. |
| Keywords: | nano-titanium dioxide visible light photocatalytic doping mechanism |
