Ni-Doped cerium oxide on rGO: A hydrothermal approach for high-performance supercapacitors
This work describes the hydrothermal method for synthesizing a novel nanocomposite: Nickel -doped Cerium oxide on reduced graphene oxide (Ni-CeO2/rGO). The resulting material exhibits exceptional electrocatalytic behavior, showing promise for supercapacitor applications. The Phase morphology, elemental analysis, surface area and oxidation state were confirmed by powder X-ray diffraction studies (PXRD), Raman spectrum, High Resolution Transmission Electron Microscopy (HRTEM), Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray (EDX), Brunauer-Emmett Teller (BET) and XPS respectively. Electrochemical analysis involving cyclic voltammetry (CV), Galvanostatic charge/ discharge, and Electrochemical impedance spectroscopy (EIS). The specific capacitance is 262.1Fg-1, 504Fg-1, and 728Fg-1 for CeO2, CeO2/rGO, Ni-CeO2/rGO it depicts its suitability for energy storage. This study establishes the Ni-CeO2/rGO nanocomposite as a highly effective material for advanced energy storage applications.
