采用溶胶-凝胶法，以硝酸铜、二氯化锡和钛酸四丁酯为原料，加入十六烷基三甲基溴化铵（CTAB）作软模板，制备CuO／Sn02／TiO2纳米复合物。分别用SEM、XRD、IR、UV—vis等对产物进行表征分析，CuO／SnO2／TiO2晶粒由锐钛矿相的TiO2、金红石相的SnO2和单斜晶系的CuO组成。以甲基橙为模拟污染物，研究其催化活性，结果表明CuO／SnO2／TiO2纳米复合物具有较好的光催化活性。

The CuO/SnO2/TiO2 nanocomposite has been prepared by the sol--gel method, in which the CTAB was used as engaged-template that reacted with Cu（NO2 ）2. SnCl2 andTi（OC4 H9）4. The nanocomposite as-obtained was characterized by SEM , XRD, IR and UV-vis. The CuO/SnO2/TiO2 nanocomposite was composed of anatase crystal TiO2 and rutile crystal SnO2 and monoclinic crystal CuO. Under sunlight the photocatalytic activity of CuO/SnO2/TiO2 nanocomposite as-obtained was studied by methyl orange as simulation pollutants. The CuO/SnO2/TiO2nanocomposite had excellent photocatalytic activity.
