英文摘要	A rich reserve, low-cost electrocatalyst with high-efficiency catalytic activity is supposed to be a promising substitute for Pt-based noble metal electrocatalysts. Herein, we produced a heterostructure MoS2-Ni3S2 nanosphere on 3D nano-porous Ni through a novel synthetic strategy. Benefiting from the unique nano spherical heterostructure MoS2-Ni3S2 catalyst exhibits relatively low overpotentials of eta 10 = 109 mV and Tafel slope of 81 mV dec-1 for HER, eta 10 = 130 mV and 91 mV dec-1 for OER. Using heterostructure MoS2-Ni3S2 as bifunctional electrocatalysts, a low cell voltage of 1.49 V was required to reach a current density of 10 mA cm(-2). The outstanding performance of heterostructure MoS2-Ni3S2 is attributed to the fast charge transfer channel offered by the interface between MoS2 and Ni3S2 as well as the large surface area provided by the nanospherical structure. This work elaborates a feasible measure to realize the non-noble and high efficiency electrocatalysts and is instructive for the design of interface engineering and nanostructures.(c) 2022 Published by Elsevier B.V.
