Abstract
The objective of the current research was mainly focused on synthesizing the Reduced Graphene Oxide (RGO) using modified Hummers method and ZnO functionalized reduced graphene oxide (RGO) composite was fabricated by a one-pot approach. The ZnO functionalized graphene nanosheets were characterized by X-ray diffractometer (XRD) and surface morphology was examined using Transmission Electron Microscopy (TEM). Electrochemical characteristics of the ZnO/RGO composite were investigated through cyclic voltammetry and electrochemical impedance spectroscopy (EIS). The composite was capable of delivering a high specific capacitance with excellent cycling stability. The ZnO decorated RGO catalyst was also applied to degrade different nonvolatile compounds such as Methyl Blue (MB) and Indigo carmine (IC). The performance of RGO/ZnO shows rapid degradation of dyes of high concentrations.
