Abstract In present work, graphene was doped with nickel oxide to improve theperformance of electrochemical applications. Initially reduced graphene oxide (rGO) was synthesised by modified Hummer’s method by using Graphite as a precursor material, as synthesised rGO is used to prepare rGO/NiO nanocomposite in one step. Then the synthesised GO and rGO/NiO materials are subjected to different characterisation for rectification of the compounds. The synthesised GO and rGO/NiO compositewere characterised by using X-ray Diffracto meter (XRD) and Surface morphology examined by using Scanning Electron Microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) for functional group attachments. Graphite, rGO and rGO/NiO nanocomposites were investigated through cyclic voltammetry and electrochemical impedance spectroscopy.From, it is clear that the charge transfer resistance is low in the electrode with rGO/NiO followed by a rise in the capacitance of the electrode. From the obtained results it is confirmed that the electrochemical behaviour of rGO/NiO composites materials was superior as compared to graphite and rGO. © 2018 Elsevier Ltd. All rights reserved.
