Description
ABSTRACTScientists and researchers are investigating new energy conversion and storage devices continuously because of the current global hike in energy crisis. In this study, we utilized graphene oxide (GO) and composites of transition metallic oxides (CeO2@WO3) to fabricate electrodes intended for use in supercapacitor electrodes. These electrodes' morphology demonstrates a uniform distribution of sphere and platelet nanoparticles. The XRD measurements for these manufactured electrodes showed a noticeable crystalline character. These electrodes have outstanding electrochemical performance due to their relatively low bandgap energies. The electrochemical tests demonstrated the exceptional charge storage capabilities of the different electrodes, suggesting that CeO2/GO, WO3/GO, and CeO2@WO3/GO electrodes could be useful electrodes for supercapacitor applications. Numerous electrochemical findings made it abundantly evident that the creation of bimetallic CeO2@WO3/GO composites enhanced the supercapacitive performance and cycle stability of the electrodes.
