Fabrication of Hierarchical MOF-Derived NiCo₂S₄@Mo-Doped Co-LDH Arrays for High-Energy-Density Asymmetric Supercapacitors.

ABSTRACT: The rational fabrication of composite structures made of mixed components has shown great potential for boosting the energy density of supercapacitors. Herein, an elaborate hierarchical MOF-derived NiCo₂S₄@Mo-doped Co-LDH arrays hybrid electrode was fabricated through a step-wise method. By leveraging the synergistic effects of a uniform array of NiCo₂S₄ nanowires as the core and an MOF-derived porous shell, the NiCo₂S₄@Mo-doped Co-LDH hybrid electrode demonstrates an exceptional specific capacitance of 3049.3 F g^-1 at 1 A g^-1. Even at a higher current density of 20 A g^-1, the capacitance remains high at 2458.8 F g^-1. Moreover, the electrode exhibits remarkable cycling stability, w
