Adsorption, photocatalytic and sunlight-driven antibacterial activity of Bi2WO6/graphene oxide nanoflakes

Abstract The Bi 2 WO 6 /graphene oxide (BWO/GO) nanoflake hybrids were prepared by cetyltrimethylammonium bromide (CTAB)-assisted hydrothermal method. Compared with the pure BWO catalysts, the resultant BWO/GO nanohybrids exhibited higher adsorptive ability and visible-light photocatalytic activity for rhodamine B (RhB) under Xe lamp irradiation. Furthermore, it has a high circulative stability and antibacterial ability. This work will provide some supports for the potential applications of BWO/GO nanohybrids in photocatalysis and antibacterial materials under common environment.
