This study reports the successful synthesis of a Cu-based metal–organic framework (Cu MOF) integrated with delaminated titanium carbide MXene (D-MXene) to form composite electrode material MOF/D-MXene) for high-performance supercapacitors at graphite sheet (GS) electrode. The Cu MOF/D-MXene was fabricated using simple solution-based approach and exhibited remarkably high surface area 933 m2 g–1. exceptional synergistic interaction between MOF D-MXene resulted in an outstanding electrochemical performance. delivered specific capacitance 3249.92 F g–1 current density 1 A three-electrode system 6 M KOH electrolyte. Density functional theory calculations supported strong interfacial D-MXene, calculated binding energy −9.56 eV. Furthermore, asymmetric supercapacitor device constructed by as cathode activated carbon anode. achieved 746.53 within potential window 1.5 V. Moreover, this demonstrates excellent stability, retaining 95% its initial after 10,000 cycles 15 These findings highlight composites promising materials next-generation storage capabilities long-term cycling stability.
