| Abstract: | Hydrogen has great potential. Electrolysis of water is an efficient method for hydrogen production, but highly efficient catalysts (such as platinum, iridium/ruthenium oxides) are limited due to cost and resource issues. Therefore, in the past decade, research focus has shifted to developing low-cost non-precious metal catalysts. In this study, a novel bimetallic nanomaterial based on metal foam was synthesized in situ by designing the structure and composition of transition metal catalysts. Specifically, Cu(OH)2 nanowire arrays with a core-shell structure of NiFe-LDH were fabricated via in-situ etching of Cu(OH)2 nanowire arrays on the surface of copper foam (CF) using a simple room-temperature corrosion oxidation process, followed by immersion in a mixture of FeCl2 and NiCl2 solutions. The resulting NiFe-LDH nanowires, grown directly on the array, exhibit a large surface area that exposes more active sites, significantly enhancing electrocatalytic activity and enabling the electrode to demonstrate excellent OER performance. It exhibits excellent oxygen evolution performance in alkaline electrolytes (1 M KOH and 6 M KOH). At an overpotential of 350 mV, the current densities are 371.6 mA cm-2 and 637 mA cm-2 respectively, and it also has excellent long-term stability (≥ 30 hours).This work provides innovative insights into the design of highly stable and active electrodes.
