Abstract

Abstract: The Bi2 WO6 /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. Highlights: Bi2 WO6 /graphene oxide (BWO/GO) nanoflakes are prepared by a simple method. BWO/GO nanoflakes possess very strong adsorptive ability. BWO/GO nanoflakes display high photocatalytic activity and circulative stability. BWO/GO nanoflakes exhibit very good antibacterial ability under sunlight.
