| 英文摘要 | A new and improved photocatalyst, reduced graphene oxide (RGO)-modified Bi2WO6 (Bi2WO6-RGO), was synthesized by a two-step hydrothermal process. The effect of RGO content on photoactivity was investigated and the optimum mass ratio of RGO to Bi2WO6 was determined to be 1%. Based on scanning electron microscopic study, RGO does not change the structure and morphology of the Bi2WO6 photocatalyst. Therefore, the improvement in the photoactivity of the Bi2WO6-RGO composite is undoubtedly ascribed to RGO. The presence of graphene can facilitate the dissociation of photogenerated excitons, which leads to more O-2(center dot-) to degrade dye pollutants like rhodamine-B (RhB). Moreover, the efficient adsorption of RhB molecules on graphene is another reason for the improved photoactivity. |
