采用两步电化学沉积法在Cu衬底上沉积得到ZnO纳米结构薄膜。用X-射线衍射（XRD）和扫描电子显微镜（SEM）对其结构及形貌进行表征,发现先在Cu衬底上沉积一层Zn致密膜,更有利于在其表面上得到附着力强、形貌较好的ZnO纳米结构膜。系统考察了沉积温度和沉积时间等工艺参数对ZnO纳米结构的影响。结果表明,沉积温度和沉积时间对晶体结构和形貌有显著影响,通过对工艺进行适宜控制可以得到结晶性良好的六方纤锌矿型ZnO纳米结构膜。以罗丹明B为目标有机污染物,分析了ZnO膜的光催化性能,表明所制备的ZnO膜可以作为光催化剂,其光催化效率可达到72.4%。

ZnO nanostructure films are obtained on Cu substrate by using a two-step electrochemical deposition technique.The structures and morphologies are characterized by X-ray diffraction（XRD）and scanning electron microscopy（SEM）.It is shown that Zn compact films pre-deposited on the Cu substrate are beneficial to the growth of ZnO nanostructure films.In addition,a systematical investigation is made for the effects of the deposition temperature and time on the morphologies of the ZnO films.The results show that the deposition temperature and time have obvious impact on the morphologies of the ZnO nanostructures,and that highly-crystalline ZnO films with hexagonal wurtzite structure can be obtained through suitable process conditions.Rhodamine B is used as the target organic pollutants to explore the photocatalytic performance,indicating that the prepared ZnO films can be used as a photocatalyst whose photocatalytic efficiency is as high as 72.4%.
