Abstract

Abstract

Graphene /titania ( GR/TiO2 ) multiplex photo-catalyst was prepared through hydrothermal method by using butyl titanate and graphite oxide as precursors． The structure and character of GR/ TiO2 was carefully studied with XRD，TEM，and FT-IR． Photocatalytic activity of GR/TiO2 had been evaluated by degrading methylene blue． The factors that influence the degradation rate were also investigated，such as H2O2 dosage and pH． The results showed that the anatase TiO2 in GR/TiO2 was approximately 25 nm in diameter and scattered on the film-shaped GR． GR/TiO2 had higher photocatalytic performance under UV light and visible light and exhibited excellent stability． The proper H2O2 dosage could accelerate the reaction． In alkaline condition，MB was degraded more easily．
