Mo-Ni based materials are the favored catalysts for hydrogen evolution reaction (HER). In this work, we report the synthesis of nanoporous Mo-NiO/Ni electrocatalyst with self-standing structure through a simple dealloying method. The effect of Mo content on the morphology and electrochemical performance of the catalyst is investigated. The np-Mo6 sample delivers a low overpotential of 34 mV at 10 mA cm⁻², a Tafel slope of 49 mV dec⁻¹, and 100 h long-term stability of HER. The high specific surface area and suitable hydrogen adsorption/desorption energy contribute to the superior electrocatalytic activity and rapid kinetics. The self-standing structure prevents the loss of active components, which favors of the stability of the electrode.

Mo-Ni 基材料是析氢反应 (HER) 的首选催化剂。在这项工作中，我们报道了通过简单的脱合金方法合成具有自支撑结构的纳米多孔 Mo-NiO/Ni 电催化剂。研究了Mo含量对催化剂形貌和电化学性能的影响。np-Mo6 样品在 10 mA cm ^-2时提供 34 mV 的低过电势、49 mV dec ^-1的 Tafel 斜率和 100 小时的 HER 长期稳定性。高比表面积和合适的氢吸附/脱附能量有助于优异的电催化活性和快速的动力学。自立结构防止了活性成分的流失，有利于电极的稳定性。
