Abstract
The P-based electrode electrocatalysts have exhibited high activities for the hydrogen evolution reaction (HER), but their structural stabilities in the long-term operation of water electrolysis pose a technical challenge for industrial-scale applications. In this study, amorphous NiP sheet arrays with rich active sites were created on nickel foam (NF) by in situ phase reconstruction, and then NiO ultrafine particles were generated within the NiP sheets. The array electrode exhibited not only enhanced catalytic activity verified by 76 mV of HER for NiO@NiP/NF at 10 mA cm?2, but also excellent structural stability in 1 M KOH solution proved by the fact that the structure of the assembled electrode remained intact after long-term operation at 100 mA cm?2 for 120 h.
p基电极电催化剂在析氢反应(HER)中表现出较高的活性，但其在水电解长期运行中的结构稳定性对工业规模应用提出了技术挑战。本研究采用原位相重构的方法，在泡沫镍(NF)表面制备了具有丰富活性位点的非晶NiP片阵列，并在NiP片内生成了NiO超细颗粒。阵列电极不仅表现出了增强的催化活性，通过对NiO@NiP/NF在10 mA cm?2、在1 M KOH溶液中具有优异的结构稳定性，在100 mA cm?2, 120小时。
