还原氧化石墨烯负载极性面占优氧化锌对亚甲基蓝的光催化降解
ZnO disks loaded with reduced graphene oxide for the photodegradation of methylene blue
摘要
Abstract
Graphene oxide was loaded onto ZnO disks with dominant polar facets and photo-reduced to form ZnO-RGO photocat-alysts. Their photocatalytic activity for methylene blue degradation is remarkably improved under UV-visible light irradiation. The enhanced activity is ascribed to the trapping effect of RGO for photoexcited electrons that inhibits electron/hole recombination and to the adsorption effect of RGO for methylene blue to increase its local concentration. The optimal loading of the RGO is ca. 2 mass%, above which light absorption by the RGO decreases the photo utilization efficiency.关键词
