摘　　要：以Cu粉和S粉作为前驱体,低温(40℃)下生成的CuS原位浸渍到具有锐钛矿和金红石混合晶相的TiO_2载体上,成功制备了复合型光催化剂。对该催化剂的晶相结构、颗粒大小、CuS存在状态以及光学性质进行了表征,考察了CuS不同负载量对TiO_2光催化性能的影响。结果表明,CuS的复合没有影响TiO_2的晶相结构和粒径,此复合型光催化剂的活性比CuS或TiO_2的光催化活性都高。Cu and S powders were used as precursors,and TiO2 was synthesized by in-situ impregnation of CuS at low temperature(40℃),and the composite photocatalysts were successfully prepared on the anatase and rutile mixed crystal phases.The crystal structure,particle size,CuS state and optical properties of the catalyst were characterized.The influence of CuS loading on the photocatalytic activity of TiO2 was investigated.The results showed that the CuS composite had no effect on the crystal structure and particle size of TiO2,and the activity of the composite photocatalyst was higher than that of CuS or TiO2.
