The photocatalysts for C and Nd doped or codoped TiO₂ were prepared by sol-gel method using tetrabutyl titanate, neodymium nitrate hexahydrate and glucose as a source of titanium, source of neodymium, and source of carbon, respectively. Its structure and properties were characterized by means of XRD, XPS, diffuse reflectance, SEM and physical adsorption. The results showed that the major crystalline form of C and Nd codoped titanium was the anatase, the surface was smooth, pore size distribution was in the range of 20~34 nm, crystalline size was dispersed uniformly. Compared to the other three catalysts, the surface area of codoped catalyst was larger. The formation of new energy bands E_C2p and E_Nd³⁺4f by doping C and Nd reduced the electron transition energy, and it was beneficial to enhance the photocatalytic activity of codoped TiO₂. Codope can significantly improve the absorption of visible light, its degradation effect on methyl orange was significantly increased, the decolorization rate was 61.24%.
