采用阴阳离子表面活性剂复合囊泡相为软模板，自组装合成了Cu-Zn复合氧化物纳米材料，分析了自组装过程。研究了铜的掺杂量对纳米材料的形貌、晶型、能级变化以及电子结构的影响，评价了不同铜掺杂量的ZnO-CuO样品光催化性能。结果表明，随着铜掺杂量的增加，样品ZnO-CuO中ZnO的X射线衍射（XRD）特征峰强度逐渐降低；形貌由多面体晶粒转向片层结构；铜的引入使ZnO的发光能级发生变化，并随着铜离子的量增加，光生载流子浓度变小。可见光催化结果显示，样品 ZnO-CuO 光催化性能随掺杂铜离子量的增加先增加后减弱。在金属离子Cu2+和Zn2+物质的量之比为5：95时光催化效果为最佳。

Assisted with the soft template of vesicle phase complicated by anionic and cationic surfactants, nano Cu-Zn oxide composite was synthesized via self-assembly. The effects of the concentration of Cu2+ on the morphology, crystalline, changes in the electron energy levels and electronic structure of the nanomaterials were investigated, and the visible-light photocatalytic property of the ZnO-CuO samples were evaluated. The results showed that with the increased amount of copper, the intensities of the characteristic peaks of ZnO sample were gradually decreased, and the morphology was transformed from polyhedral grains to a lamellar-sheet structure. With the introduction of copper, the energy level changed. With the increasing amount of copper, the density of the photo-generated carriers decreased, and the photocatalytic property of the composite first increased then decreased. The sample with a molar ratio of Cu2+ and Zn2+ ions of 5:95 exhibited the best photocatalytic property.
