摘要
用溶胶-凝胶法制备了Fe/Si/TiO2三元复合光催化剂,利用X射线衍射(XRD)和紫外-可见漫反射光谱(DRS)对样品进行了分析表征,并以甲基橙为模拟污染物,考察了其光催化活性。结果表明,Fe/Si/TiO2三元复合光催化剂与TiO2相比,光催化活性明显提高;当煅烧温度为900℃、添加Fe的摩尔分数为0.050%时,光催化活性最佳。
The Fe/Si/TiO2 three-element composite photocatalyst were prepared by sol-gel method and characterized by XRD and DRS. The photocatalytic activity were investigated by the photocatalytic degradation of methyl orange. The results showed that the photocatalyst had higher photocatalytic activity, when the calcination temperature was 900℃ , the photocatalytic activity of 0. 050% Fe （in mole） added was the best of all the prepared samples.
