It is highly attractive to develop efficient hydrogen evolution reaction (HER) electrocatalysts under alkaline conditions. In this communication, we report the preparation of amorphous Ni(OH) decorated FeP nanoarray on Ti mesh (Ni(OH)-FeP/TM) via electrodeposition. As a 3D electrode for the hydrogen evolution reaction, such Ni(OH)-FeP/TM demonstrates superior catalytic activity. Moreover, the as-prepares electrocatalyst requires an overpotential of only 76 mV to drive a current density of 10 mA cm, which is 94 mV less than that for FeP/TM. It also shows strong long-term electrochemical durability with its catalytic activity being maintained for at least 20 h.
在碱性条件下开发高效的析氢反应（HER）电催化剂极具吸引力。在本通讯中，我们报道了通过电沉积在钛网上制备非晶态Ni(OH)修饰的FeP纳米阵列（Ni(OH)-FeP/TM）。作为用于析氢反应的三维电极，这种Ni(OH)-FeP/TM表现出卓越的催化活性。此外，所制备的电催化剂驱动10 mA cm电流密度仅需76 mV的过电位，比FeP/TM低94 mV。它还表现出很强的长期电化学耐久性，其催化活性至少保持20小时。
