Abstract TiO₂ has the advantages of good chemical stability, high catalytic activity, no pollution, and low price, and has broad development prospects in the field of photocatalysis. The bandgap of TiO₂ affects its absorption of visible light, which is not conducive to the promotion and utilization of TiO₂ in production and life. The research progress of co-doping modified TiO₂ in the field of photocatalysis was reviewed and the photocatalysis mechanism of nano-TiO₂ was introduced. The influences of different modification methods such as metal/metal co-doping, non-metal/non-metal co-doping and metal/non-metal co-doping on the photocatalytic properties of TiO₂ were analyzed and compared. The co-doping modification can improve the photocatalytic activity of TiO₂ by reducing the band gap, producing visible light effect and inhibiting the recombination of electron and hole. Finally, the research results of the mechanism of co-doping and the coordination between ions were summarized, the shortco-mings of the current research on co-doped TiO₂ were pointed out, and the future research direction was put forward.

Key words： TiO₂ co-doping catalyst nanomaterials environment
