Exploring efficient, abundant, low-cost and stable materials for hydrogen evolution reaction (HER) is highly desired but still a challenging task. Herein, Ni–Se–Mo electrocatalysts supported on nickel foam (NF) substrate were synthesized by a facile one-step electrodeposition method. The Ni–Se–Mo film presents high electrocatalytic activity and stability toward HER, with a low overpotential of 101 mV to afford a current density of 10 mA cm−2 in 1.0 M KOH medium. Such excellent HER performance of Ni–Se–Mo film induced by the synergistic effects from Mo-doped Ni–Se film leads to the fast electron transfer. This work provides the validity of interface engineering strategy in preparing highly efficient transition metal chalcogenides based HER electrocatalysts.

镍泡沫上Ni-Se-Mo膜的一步式恒电位电沉积,用于碱性氢释放反应

迫切需要探索高效,丰富,低成本和稳定的氢释放反应(HER)材料,但仍是一项艰巨的任务。在此,通过一种简便的一步电沉积方法合成了泡沫镍(NF)上负载的Ni-Se-Mo电催化剂。Ni-Se-Mo膜具有较高的电催化活性和对HER的稳定性,在1.0 M KOH介质中具有101 mV的低过电势,可提供10 mA cm -2的电流密度。钼掺杂的镍硒薄膜的协同作用导致镍硒钼薄膜具有如此优异的HER性能,可实现快速的电子转移。这项工作为制备高效的过渡金属硫族化物基HER电催化剂提供了界面工程策略的有效性。
