Reviewed were the current status and developing tendency for photocatalysis of metal ion doped naon-TiO2, including doping mechanism, and preparation methods of doped-TiO2 since 1998. Also discussed were the influencing factors such as different kinds, concentration, energy level, electronic configuration, radius, and combination valence of doped metal ion on photocatalytic efficiency and spectral response range of nano-TiO2. Some opinions on these problems were proposed.
