摘要

以醋酸锌和氧化钨(WO3)为前躯体

通过液相溶胶凝胶法制备氧化锌/氧化钨(ZnO/WO3)微米球光催化剂

利用扫描电子显微镜、X射线粉末衍射仪、紫外可见分光光度计等测试方法对样品形貌、组成和光吸收性能进行表征.以染料亚甲基蓝为目标降解物

在紫外光照射下

研究所制备样品的光催化活性.结果表明

W的加入可有效提高ZnO光催化活性.当ZnO中W掺杂浓度为4 mol%时

实验制备出的ZnO/WO3微米球光催化剂的催化效果相对于其他浓度最好

通过紫外光光照仅需80 min即可使亚甲基蓝的降解率达95%.

Abstract

A zinc oxide/tungsten oxide(ZnO/WO3) microsphere photocatalyst was prepared by liquid phase sol-gel method using zinc acetate and tungsten oxide(WO3) as precursors.The morphology

composition and light absorption properties of the samples were characterized by scanning electron microscopy

X-ray powder diffractometry and UV-visible spectrophotometer.The photocatalytic activity of the prepared sample was studied under the irradiation of ultraviolet light with the dye methylene blue as the target degradation product.The results show that the addition of W can effectively improve the photocatalytic activity of ZnO.When the W doping concentration of ZnO is 4 mol%

the prepared ZnO/WO3 photocatalyst has the best catalytic effect

and the degradation rate of methylene blue in the ultraviolet light for 80 min is 95%.
