Transition metal oxides/carbon nanocomposites derived from metal-organic frameworks (MOFs) with enhanced electronic conductivity and high theoretical capacitance have been viewed as novel porous nanostructured electrode materials for electrochemical energy storage applications. Herein, sodium ion-intercalated MoO3/NiO/C nanostructures derived from MOFs were prepared through a facile solvothermal approach and followed by calcination at 400 & DEG;C. The as-synthesized nanocomposites were characterized using FT-IR, FESEM, EDX, XRD, TEM, and TGA. Benefitting from the synergistic effects and improved ionic transfer channels, the delivered maximum electrochemical capacitance was 548.41 F g(-1) in 2-M KOH. Moreover, the electrochemical property was analyzed in terms of CV, EIS, and GCD, respectively, in a two-electrode system in an environmental-friendly aqueous electrolyte and a high energy density of 17.93 Wh kg(-1) was acquired when a symmetric supercapacitor device was assembled. Besides, a remarkable retained specific capacitance and coulombic efficiency were approximately at 99.67% and 96.66% after 8000 continuous cycles. It evidently revealed the potential application of MOF-derived metal oxides/carbon composites in high-performance electrochemical energy storage devices.
