| 摘 要： | 为了提高TiO2的光催化性能，本文制备了SO4^2-／TiO2-SnO2固体超强酸（STS），采用1R对STS的结构进行了表征，采用UV—Vis对光催化产物进行了分析，研究了STS光催化甲基橙降解的性能，结果表明适宜的制备条件为：n（TiO2）：n（SnO2）=12，焙烧温度为450℃，焙烧时间为4h，硫酸浓度为0．5mol／L，催化剂用量为0．3g／200mL，甲基橙降解率可达93％。IR分析表明在STS中形成了超强酸活性中心，UV-Vis分析表明甲基橙降解较为完全。

| Abstract: | In order to improve the photocatalytic property of TiO2, The super solidacid SO42-/TiO2-SnO2 （STS） was prepared, IR was made, The degradation of methyl orange with STS as photocatalysts were studied by UV-Vis, The results showed that the suitable preparing condition was ＂ n（TiO2） ＂ n（SnO2）= 12,the baking temperature was 450℃, the baking time was 4h, the concentration of sulfuric acid was 0. 5 mol·1^-1 , the quantity of the catalyst was 0. 3g/200mL, the degradation rate of methyl onange can reach 93%, IR showed that the super acid center was formed in SST, UV-Vis showed that methyl orange was degraded completely. |
