γ-Fe2O3/SiO2/GR/TiO2复合光催化剂的制备及可见光光催化性能研究
Study on Preparation of γ-Fe2O3/SiO2/GR/TiO2 Composite Photocatalyst and Visible Photocatalytic Properties
摘要
Abstract
γ-Fe2O3/SiO2/GR/TiO2 composite photocatalyst was prepared by using sol-gel method.The structure,morphology,absorption spectrum and magnetic property of the samples were characterized by XRD,TEM,DRS and VSM.Photocatalytic activity and stability of the composite photocatalyst were evaluated by the degradation of methylene blue solution under visible light.The results indicated that the composite photocatalyst had high photocatalytic activity under the visible light.Graphene can effectively increase the photocatalytic activity of TiO2 by reducing recombination of the electron-hole pairs and enhancing the absorption of TiO2 in the visible light region.The composite photocatalyst remained high photocatalytic activity after being reused for several times..关键词
