After summarizing in detail the research on p-type doping with group- V elements including N, P and As, this article describes the technology of codoping and presents some areas where more work is needed.

Codoping of nitrogen and appropriate amount of iron in TiO2 enhances photoresponse and utilizing efficiency in visible light region,and then improves the performances of Fe-TiO2-xNx photocatalyst.

The effects of the amount of codoping with Eu3+ and Gd3+ on the photocatalytic activity for photocatalytic degradation of methylene blue in solution and phase structure are investigated.
