▎ 摘　　要

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.
