As can be seen from Table 2, all band gap of doped-TiO2 are narrowed and its absorption of visible light are increased compared with that of pure TiO2, which is why the catalytic effect of visible light is enhanced. Among which, the band gap of N, Cd-TiO2 is the smallest, and their optical absorption are the strongest.
