摘要:
采用溶胶-凝胶法制备出一系列石墨烯(GE)负载ZnO光催化剂,利用X射线衍射仪和紫外-可见漫反射光谱仪等仪器对合成的催化剂进行表征,考察了光源、ZnO/GE质量比、光催化剂用量以及染料废水质量浓度对催化剂性能的影响。结果表明:ZnO在GE上晶面生长完整,结晶度良好;GE提高了ZnO的光量子利用率;在紫外光,ZnO/GE质量比为0.5,催化剂用量(占反应体系的质量分数)为4%,染料废水质量浓度为15 mg/L的最优条件下,染料降解率高达84%。
Abstract:
A series of graphene (GE) supported ZnO photocatalysts were prepared by sol-gel method. The synthesized catalysts were characterized by X-ray diffractometer and ultraviolet-visible diffuse reflectance spectrometer. The effects of light source, ZnO/GE mass ratio, photocatalyst dosage and dye wastewater concentration on the performance of the catalysts were investigated. The results showed that the growth of ZnO on the crystal surface of GE was complete and the crystallinity of the catalysts was good. The use of GE increased the photoquantum efficiency of ZnO. Under the optimal conditions of ultraviolet light, ZnO/GE mass ratio of 0.5, catalyst dosage (mass fraction of the reaction system) of 4%, and dye wastewater concentration of 15 mg/L, the dye degradation rate was as high as 84%.
