Abstract

A novel electrode material of three-dimensional hierarchical NiCo₂S₄@NiMoO₄core/shell nanospheres was synthesized by a facile two-step hydrothermal method. These hierarchical NiCo₂S₄@NiMoO₄core/shell nanospheres exhibit a high specific capacitance of 1714 F g⁻¹at a current density of 1 A g⁻¹, which indicated the excellent electrochemistry performance.
