| Summary: | The increasing global energy demand and a shift towards sustainable energy solutions necessitate the development of advanced energy storage devices, with supercapacitors emerging as key candidates. Achieving high energy density without compromising power density remains a critical challenge, underscoring the need for novel materials with robust pseudocapacitive behavior. This study introduces a novel electroactive composite, CM-II, composed of Cr _2 CT _x MXene and a Cu-based MOF, Cu-PTC. The synthesis, structural, and morphological characterization of CM-II is extensively detailed. Cr _2 CT _x MXene provides a conductive scaffold, while Cu-PTC contributes redox-active sites and porosity, creating a synergistic combination that enhances charge storage. The pseudocapacitive performance of CM-II has been systematically evaluated, with a specific capacitance of 3035 F g ^−1 and a long cycle-life with a capacitance retention of 96% after 5000 cycles, showcasing its potential as a high-performance material for next-generation supercapacitors. |
