采用简单水热法制备得到棒状、铅笔状和塔状不同形貌的纳米ZnO阵列。采用扫描电镜（SEM）、X射线衍射（XRD）、光致发射光谱对样品结构、形貌、光学性能和催化性能进行表征;结果表明,样品晶型比较完整,PL谱图表明样品在380nm左右都出现了强烈的紫外发射峰。同时,以甲基橙为模拟污染物,通过光催化测试表明,产品均具有良好的光催化性能,其中塔状纳米ZnO的光催化性能较高。
Nanorod,pencil-like and tower-like nano-ZnO array were prepared by hydrothermal method in this study.The structure,morphology and optical properties of nano-ZnO array samples were characterized by transmission electron microscopy(SEM),X-ray diffraction(XRD) and photoluminescence spectroscopy.The results showed that the crystal of nano-ZnO array sample was better with a strong UV emission peak at 380nm.Meanwhile,the photocatalytic investigations showed that the nano-ZnO array sample have good photocatalytic properties for degradation of the simulated pollutants(methyl orange),and the tower-like nano-ZnO have higher photocatalytic properties than others.
