3D Mo-doped Ni3S2 mesoporous nanostructures on Ni foam were successfully synthesized via the solvothermal method, which showed the superior properties for energy storage and conversion. As an electrode for supercapacitor, 3D Mo-doped Ni3S2 mesoporous nanostructures demonstrated a 604.4 μAh cm-2 specific capacity and good cycling stability. Furthermore, Mo-doped Ni3S2 mesoporous nanostructures exhibited superior hydrogen evolution reaction and oxygen evolution reaction properties and good cycle stability for water splitting. At 1.41 V, the electrolyzer made up of Mo-doped Ni3S2 mesoporous nanostructures reached the 10 mA cm-2 catalytic current density, demonstrating outstanding long-term durability. Furthermore, the physical characterization results and mechanism of the 3D Mo-doped Ni3S2 were investigated. Therefore, the study presents the great promise of the 3D Mo-doped Ni3S2 mesoporous nanostructures in energy conversion and storage.

Three dimensional Mo-doped Ni3S2 mesoporous nanostructures have been successfully fabricated on Ni foam by a facile solvothermal route, which demonstrated the superior galvanization charging/discharging (GCD), hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) performances at various temperatures. The study opens new the opportunities to develop the self-supported noble-metal-free nanostructures for sustainable energy systems.
