Nickel oxide (NiO) and reduced graphene oxide (RGO)/NiO composite were synthesized by the hydrothermal method followed by calcination in air.The reduction of graphene oxide (GO) happened in a one step process through the hydrothermal method.For supercapacitor application, the specific capacitance of NiO and RGO/NiO reached 310 F/g and 360 F/g at a current density of 0.5 A/g, respectively.The RGO/NiO composite shows slightly improved electrochemical performance in comparison with pure NiO, which attributed to the fact that RGO increases electron transfer rate during the electrochemical process.
