Pathogenic bacteria have been threatening the daily life of human beings.More effective methods without causing drug-resistance of bacteria need to be developed to fight against these pathogens.Herein,flower-like CuS/-graphene oxide (GO) hybrids have been successfully syn-thesized via simple one-pot hydrothermal process.GO worked as an excellent electron acceptor to transport the photogenerated electrons from CuS,which can suppress the recombination of hole-electron pairs efficiently,thus enhancing the photocatalytic property.In addition,the morphology of CuS and GO with high specific surface area and the increased defect in GO also improved photocat-alytic performance of the hybrid.Owing to the synergy of photothermal,enhanced photocatalytic effect and released Cu ions,CuS/GO exhibited outstanding antibacterial effi-cacy under visible light irradiation for 15 min.Addition-ally,the hybrid showed great biocompatibility to L929 cell.Hence,the synthesized CuS/GO would be a promising antibacterial material for daily life including rapid water disinfection and wounds sterilization.
