摘　　要：以锌片为锌源及基片,采用溶剂热法合成出不同形貌的ZnO微米薄膜(碎石状、蘑菇状、长棒和短棒状).利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等测试手段对样品的结构和形貌进行了表征.另外,对产品的光学(紫外可见漫反射和光致发光)性能及光催化活性进行了表征和对比,同时还讨论了形貌对光催化活性的影响.Micmstmctttred ZnO films with different morphologies （fragmental block,mushroom,long-rod and short- rod） were successfully synthesized by a solvothermal routte in different solvents using Zn foil as both the substrate and Zn source. The structures and morphologies of products were characterized with X-ray diffraction （ XRD）, scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. In addition, the optical properties （UV-visible diffuse reflectance and photolumineseenee） and photocatalytie activities of products were compared. The effects of moroholo~ on the photocatalvtic activity was also discussed in this paper.
