Abstract

ZnO nanostructures of different morphology (Rods, spindles, stars, buds) were successfully synthesized by co‐precipitation method. The prepared ZnO nanostructures were systematically characterized by X‐ray diffraction, Scanning electron microscopy (SEM). XRD results show the prepared nanostructures were in the hexagonal wurtzite structure. The photocatalytic degradation of methylene blue (MB) in aqueous solution under UV‐irradiation was investigated with different ZnO nanostructures. The photocatalytic experiments reveal that spindle like nanostructures showed fast photocatalytic activity compared to the other rods, stars and buds like nanostructures.
ZnO纳米结构光催化性能的形貌依赖性研究
采用共沉淀法成功合成了不同形貌的ZnO纳米结构(棒状、纺锤状、星形、芽状)。用X射线衍射、扫描电镜对制备的ZnO纳米结构进行了系统表征。XRD结果表明,所制备的纳米结构为六方纤锌矿结构。研究了不同ZnO纳米结构对水溶液中亚甲基蓝(MB)的紫外光催化降解。光催化实验表明,纺锤形纳米结构比杆状、星状和芽状纳米结构具有更快的光催化活性。
