In this present investigation, reduced graphene oxide (rGO)–SnO2 nanocomposites were synthesized via hydrothermal and microwave methods. The nanocomposites were characterized using Fourier transform infrared spectra (FTIR), Scanning electron microscopy (SEM), Thermogravimetric analysis (TGA), and cyclic voltammetric (CV) methods.The SEM images demonstrated different morphologies and the TGA equally showed different thermal behavior of the nanocomposites. Some conditions such as concentrations and synthetic procedures were varied in order to optimize the nanocomposites formulation and devise the means for excellent product applications. The results of the research showed that the nanocomposites have higher activity under microwave assisted conditions.
