Abstract: The increasing demand for sustainable energy storage has driven advancements in materials for supercapacitors, devices known for high power density and rapid charge/discharge cycles. This study explores the potential of chromium-modified cerium-based metal-organic frameworks (Cr-Ce-MOF) as advanced electrode materials for supercapacitors. Synthesized via a solvothermal method, the Cr-Ce-MOF exhibited enhanced structural and electrochemical properties due to synergistic effects between cerium and chromium. The material achieved a high specific capacitance of 646F/g at 1A/g and energy density 22.43 Wh kg-1and power density 249.9 W kg-1retained 92% of its capacitance after 5000 cycles at 5 A/g. Characterization techniques, including FTIR, XRD, SEM, and electrochemical analysis, confirmed the improved conductivity, porosity, and redox activity imparted by chromium doping. These findings highlight Cr-Ce-MOF as a promising candidate for next-generation energy storage solutions.
