ABSTRACT

An improved, cost effective and facile hydrothermal method was made for the synthesis of SnO₂ spherical reduced graphene oxide (rGO) composites (CPs), (SCGs) by using Teflon bottle based on one-step in situ reaction between tin (II) chloride and GO. As synthesis SCGs were characterized by Fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible (UV-vis) spectroscopy, and clearly confirmed by X-ray diffraction (XRD) with adjacent lattice fringe spacing of about 0.343 and 0.233 nm correspond to the (110) plane and (101) plane of the SnO₂ spherical, respectively. The spherical of SnO₂ were uniformly self-assembled on the surface of cuboid like rGO nanosheets has been confirmed by scanning electron microscopy (SEM).
