TiO2/石墨烯复合光催化剂的制备及其吸附与光催化降解性能
Preparation of TiO2/graphene composite photocatalyst and its adsorptive and photocatalytic performance
摘要
Abstract
In recent years,graphene has become a research focus because of its unique electrical properties and high specific surface area.In this study,graphene was prepared by the oxidation-reduction method,and then TiO2/graphene (GN) composite photocatalyst was prepared by hydrothermal method.The composite was characterized by TEM,XRD,BET,UV-Vis DRS.The experiment showed that with the increase of graphene ratio,the light absorption region of the composite expanded into visible region,and its surface area increased.The TiO2/graphene has better adsorption and photocatalytic degradation efficiency for methylene blue (MB).The saturated adsorption capacity of P25-10％ GN for MB is 50mg/g at pH 8 and room temperature.关键词
