Abstract：

Abstract　A　novel　ternary　nanocomposite　photocatalyst　consisted　of　reduced-graphene-oxide　(RGO),　Bi2MoO6　and　plasmonic　Au　nanoparticles　were　successfully　fabricated　by　multiple　steps　including　a　simple　solvothermal　process　and　photochemical　reduction　process.　RGO/Bi2MoO6/Au　was　characterized　by　X-ray　powder　diffraction　patterns,　transmission　electron　microscopy,　UV-vis　diffuse　reflectance　spectra,　Raman　spectroscopy　and　X-ray　photoelectron　spectroscopy.　In　comparison　with　Bi2MoO6,　RGO/Bi2MoO6　and　Au/Bi2MoO6,　RGO/Bi2MoO6/Au　exhibits　an　enhanced　photocatalytic　activity　for　decomposition　of　Rhodamine　B　under　visible　light.　The　separation　efficiency　of　the　photogenerated　holes　and　electrons　on　Bi2MoO6　is　promoted　by　the　combined　effect　of　both　RGO　and　Au　in　the　ternary　composite,　and　thus　enhances　photocatalytic　activity.　The　scavenger　study　revealed　that　both　hole　and　superoxide　are　the　major　reactive　species　for　the　photocatalytic　degradation　of　Rhodamine　B　using　RGO/Bi2MoO6/Au　photocatalyst.　©　2015　Elsevier　B.V.
