Fe Doped TiO2 nanoparticles were successfully prepared by coprecipitation precipitation meth- od. Using the reaction of photocatalytic degradation of pentachlorophenol （PCP） as a model, its photocata- lytic degradation efficiency utilizing visible light effectively was investigated with different photocatalytic and degradation system. Results indicate that the crystal form of photochemical catalyst is still anatase form,particle diameter smaller, specific surface area larger, and visible light enhanced as the proper Fe depositing on the TiO2 ...
