alpha-SnWO4/reduced　graphene　oxide　(RGO)　nanocomposite　was　prepared　via　a　facile　one-pot　hydrothermal　reaction　between　GO,　SnCl2　center　dot　2H(2)O　and　(NH4)(5)H-5[H-2(WO4)(6)]center　dot　H2O.　A　simultaneous　reduction　of　GO　to　RGO　and　the　formation　of　nanocrystalline　alpha-SnWO4　on　RGO　was　achieved　without　using　any　extra　reducing　agent.　The　as-prepared　alpha-SnWO4/RGO　nanocomposite　was　fully　characterized　by　X-ray　diffraction　(XRD),　fourier　transformation　infrared　spectroscopy　(FT-IR),　Raman,　X-ray　photoelectron　spectroscopy　(XPS),　transmission　electron　microscopy　(TEM),　high-resolution　transmission　electron　microscopy　(HRTEM)　and　N-2-sorption　BET　surface　area.　The　photocatalytic　performance　of　the　sample　was　investigated　by　the　decomposition　of　Methyl　Orange　(MO)　under　visible　light　irradiation.　The　electrochemical　properties　of　alpha-SnWO4/RGO　and　alpha-SnWO4　as　anode　materials　were　revealed　for　the　first　time.　alpha-SnWO4/RGO　nanocomposite　showed　improved　photocatalytic　activity　and　enhanced　anode　performance　for　Li-ion　batteries　as　compared　to　pure　alpha-SnWO4.
