摘要
Reduced graphene oxide/Bi2WO6 (RGO-Bi2WO6) composite photocatalysts were prepared by a simple one-pot method. Namely, the reduction of graphene oxide and the growth of Bi2WO6 crystal occurred simultaneously in one single process. The obtained samples were characterized by XRD, SEM, and DRS. The photocatalytic activities of as-prepared samples was investigated by degradation of MB under visible light irradiation. An enhancement in photocatalytic activities were observed in RGO-Bi2WO6 composites compared with pure Bi2WO6. We also investigated the effect of graphene amount on the photocatalytic activity of the as-prepared composite photocatalysts. Results showed that there was an optimal amount of 2.5%.
