摘要/Abstract

摘要： 用化学沉淀法制备一种花球状ZnO结构(ZnO-F), 并通过扫描电子显微镜(SEM)和透射电子显微镜(TEM)表征样品结构, 用X射线粉末衍射(XRD)、 X射线光电子能谱(XPS)和能量散射谱（EDS）分析样品成分, 用紫外可见漫反射光谱(DRS)和荧光光谱（PL）分析样品的光电性能, 通过光催化降解亚甲基蓝(MB)研究ZnOF的光催化活性. 结果表明：所得产物是直径约为1 μm的ZnO, 其花球结构由约为17 nm的纳米片交叉组装而成；样品具有较高的光催化活性, 240 min内光催化降解MB的效率超过90%.

Abstract: Flower-like ZnO (ZnO-F) structure was prepared by chemical precipitation method. The sample structure was characterized by scanning electron microscope (SEM) and transmission electron microscope (TEM), the composition of sample was analyzed by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and energy dispersive spectroscopy (EDS), the photoelectric performance of the sample was analyzed by UV-visible diffuse reflectance spectroscopy (DRS) and fluorescence spectroscopy (PL), and the photocatalytic activity of ZnO-F was studied by photocatalytic degradation of methylene blue (MB). The results show that the product is ZnO with a diameter of about 1 μm, and its flower-like structure is formed by cross assembly of nanosheets with a diameter of about 17 nm. The sample has high photocatalytic activity, and the photocatalytic degradation efficiency of MB exceeds 90% within 240 min.

Key words: chemical precipitation method, flower-like ZnO, photocatalytic activity, catalytic degradation, methylene blue (MB)
