Synthesis of Silver Vanadium Tetraoxide/Graphene Oxide Composite and Its Visible-light Photocatalytic Performance
摘要
Abstract
Silver vanadium tetraoxide and graphene oxide ( Ag3 VO4/GO ) composites were prepared by Hummers and liquid phase precipitation methods respectively .The obtained samples were characterized by X-ray diffraction ( XRD ) , scanning electron microscopy ( SEM ) , and ultraviolet-visible ( UV-Vis ) diffuse reflectance spectroscopy .The effect of GO content on the photocatalytic activity of Ag3 VO4 was evaluated by photocatalytic degradation of methyl orange (MO) under visible light irradiation (λ≥420 nm).The results show that GO dopped Ag3 VO4 nanoparticles can improve the degradation efficiency .At the optimal GO content (2%mass fraction), the degradation rate of MO over GO/Ag3VO4 is 89% after 30 min of light irradiation, exhibiting 1.6 times higher activity than that of pure Ag3 VO4 .关键词
