Abstract
This article reports the synthesis beta-SnWO4-rGO nanocomposite (NC) by a simple solution combustion method followed by low temperature hydrothermal method. The beta-SnWO4-rGO NC has been characterized using various analytical tools such as X-ray diffraction (XRD), Raman spectroscopy, Scanning Electron Microscopy (SEM), High-Resolution Transmission Electron Microscopy (HR-TEM), Ultraviolet-Differential reflectance spectroscopy (UV-DRS). X-ray diffraction pattern shows the formation of cubic structured beta-SnWO4 nanoparticles (NPs) and Raman spectrum shows the presence of rGO in the composite. Transmission Electron Microscopy image shows that SnWO4 NPs were embedded on the surface of rGO. beta-SnWO4 NPs and beta-SnWO4-rGO NC has been examined as an electrode material for Li-ion battery (LIB). beta-SnWO4 NPs and beta-SnWO4-rGO NC displays an initial discharge capacity of 1351 mAhg(-1) and 1662 mAhg(-1) which is about 23% increase in capacity. Electrochemical performance of beta-SnWO4-rGO NC at different current densities proves that it is one of the good candidates as an electrode material for LIB. beta-SnWO4-rGO NC shows enhanced photocatalytic activity against rose bengal (RB) and methylene blue (MB) compared to pure beta-SnWO4 NPs.
