TiO_2-SO_4^(2-)/Glass光催化降解甲基橙溶液的方法

A Study of Photo-catalytic Degradation of Methyl Orange by TiO_2-SO_4^(2-)/Glass

研究以平玻璃和毛玻璃为载体,用Sol gel法制备附载型TiO2/Glass光催化剂,并用H2SO4溶液浸泡制得TiO2 SO2-4/Glass光催化剂。考察了光催化剂对甲基橙溶液的光催化性能。结果表明:平玻璃附载TiO2的光催化活性低于毛玻璃附载TiO2的光催化活性。且毛玻璃附载TiO2经连续6次使用后光催化活性基本不变。毛玻璃附载TiO2经H2SO4溶液处理后光催化活性明显升高。

This paper presents the preparation of TiO 2 SO 2- 4/Glass (both ordinary glass and ground flat glass) by the sol gel method and the examination of the photo catalytic performances. The results showed that the one using ground glass as a carrier had better photo catalytic activity and longer life span. It was concluded that TiO 2 adherent on ground glass and then treated with H 2 SO 4 solution could greatly upgrade photo catalytic performance.
