| Abstract: | Due to broader band gap,nano-TiO2 was only excited by UV-light.It was main problem to extend the photoactivity of titania-based systems into the visible light region.The mechanism of photocatalytic activity of nano-TiO2 was analyzed in the paper,normal doping methods of nano-TiO2 were discussed,and its application was also previewed. |
