Abstract This research studied the electrochemical performance of reduced Graphene Oxide (rGO) and a nanocomposite comprising rGO Metal–Organic Framework-5 (MOF-5) for supercapacitor applications. The nanocomposite, synthesized through solvothermal method, aimed to capitalize on synergistic effects combining with MOF-5 under normal laboratory conditions without utilizing autoclave. By adjusting concentration oxidizing agent, oxidation degree was effectively regulated, thereby influencing its structural properties. Utilizing optimized rGO, electrodes were fabricated both MOF5-rGO configurations. Electrochemical studies carried out using three-electrode (3E) system 6M KOH electrolyte. MOF-5, graphene oxide (rGO), samples characterized x-ray powder diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) determine their chemical composition information. Impedance Spectroscopy (EIS) spectra show low internal resistance (R s ) charge transfer ct ), indicating higher conductivity nanocomposite. electrode in 3E showed specific capacitance 65 Fg −1 whereas displayed 73 at current density 1.2 Ag . demonstrates better capacitor retention (96%) compared (90%) 5A/g. These results indicate that sample is promising application.
