摘要：Iron ion and chromium ion doped TiO2 films were prepared on the surface of glazed brick by the sol-gel process, and the effect of iron ion and chromium ion doping on photocatalytic activities of TiO2 films was investigated. The results of photodecomposing Rhodamine B show that an appropriate doping amount of iron and chromium ion can improve the photocatalytic activities of TiO2 films, however, the photocatalytic activities of iron ion doped samples are remarkably higher than those of chromium ion doped samples, while the doping ways of chromium ion affect the photocatalytic activities of TiO2 films, because of their different doping mechanisms.
