摘    要:采用微波方法制备具有高活性、自然光响应的膨润土负载掺银TiO2光降解催化剂,并以甲基红为目标降解物评价光降解催化剂在自然光下的催化活性.结果表明:掺银TiO2成功负载于膨润土片层表面,当银的掺杂质量分数为0.5%时,焙烧温度为600℃时,合成的光降解催化剂在自然光照射下,对pH=68甲基红废水溶液的降解率可达97%以上.

关 键 词:膨润土  掺银TiO2  光降解催化剂

Abstract:Highly efficient visible-light-induced bentonite Ag-doped TiO2photocatalysts were prepared by microwave method. The photocatalytic activity of the samples toward the methylene red was investigated under visible-light irradiation. The results showed that the Ag-doped TiO2was loaded on bentonite,and the synthesis photocatalytic activity degradation rate may reached above 97% when the Ag doped was 0. 5%,the roasting temperature was 600 ℃,pH was6 8甲基红废水溶液的降解率可达97%以上.Highly efficient visible-light-induced bentonite Ag-doped TiO2photocatalysts were prepared by microwave method.
