This paper reviewed the progress in the modification of photacatalysis under visible light of titanium dioxide, and prospected the applied prospect of titanium dioxide.The modification methods of titanium dioxide photacatalyst under visible light includes:metal ions doped,non-metallic ions doped,semiconductors compound,surface sensitization of light and co-doped.Among this the most widely used method is co-doped,because it set the advantages of other methods, to improve the performance of titanium dioxide in reducing the band gap, improving the light-absorbing capacity,reducing the electron and hole recombination and other aspects.Meanwhile summarizes its recent experimental study on the degradation of pollutants in the environment, reduction of organic matter, solar cells and so on, showing its potential applications in many fields.Finally, this paper prospected the future direction and applied prospect of titanium dioxide catalyst under visible light.
