摘要：采用溶胶－凝胶法在釉面砖表面制备了均匀的ＴｉＯ２薄膜，并研究了铁、铬离子掺杂对ＴｉＯ２光催化性能影响．对罗丹明Ｂ的光降解实验表明，适量的铁、铬离子掺杂均可提高ＴｉＯ２薄膜的光催化活性，铁离子的掺杂效果明显高于铬离子，而铬离子的掺杂方式影响ＴｉＯ２薄膜的光催化活性。
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.
