摘　　要：采用溶胶-凝胶法制备出一系列不同掺铁量的TiO2光催化剂。用靛蓝胭脂红作为模拟污染物来检验其催化活性,实验结果表明:当掺铁量为0.75%、光照时间为4h时,靛蓝胭脂红的降解率可达到99.7%;掺杂铁能够显著提高TiO2的光催化效率。A se ries of TiO2 photocatalysis with different Fe content were prepared by sol-gel method in this article. Indigo carmine was used as a simulation of pollutants to test its catalytic activity. The results showed that when the content of Fe 0.75 % of all content, illuminating time 4h, the degradation efficiency of indigo carmine rouged up to 99.70%. The TiO2 photocatalytic efficiency could be significantly improved by doping iron.
