摘要
以硅藻土为固体活性添加物 ,采用sol-gel方法水解钛酸四丁酯制备溶胶与硅藻土混合合成混杂型光催化剂 ,样品分别用XRD和FTIR表征 ;以光催化亚甲基蓝溶液为反应体系 ,用Uv -vis光谱评价在紫外光照射下活性实验 .结果表明 ,在混杂组分中含较低TiO2 的质量百分比 ,所制备的硅藻土混杂型TiO2
The mixed photocatalyst was prepared by sol-gel method using the kieselguhr as active additional substance and characterized by XRD and FTIR.Being a model reaction by ultraviolet radiation,the photocatalytic degradation of methylene blue was investigated with a mixed catalyst.The results showed that the mixed catalyst have better photocatalytic activity and decolorization effects.
