[目的]随着全球对清洁能源需求的不断增长和环境保护意识的增强，开发高效、稳定且成本低廉的电解水制氢催化剂成为推动氢能经济发展的关键。[方法]采用水热反应、高温煅烧与磷化处理相结合的方法，在泡沫镍(NF)基底上负载镍钴磷化物(Ni Co P)，得到Ni Co P/NF复合膜电极。通过扫描电镜(SEM)、X射线衍射(XRD)、氮气吸-脱附测试等手段表征了Ni Co P/NF膜电极的形貌和结构，通过电化学测试研究了不同因素对电极析氧反应(OER)和析氢反应(HER)活性及电池性能的影响。[结果]当NaH_2PO2·H_2O质量浓度为125 g/L时，Ni Co P/NF膜电极展现出最优的OER与HER活性。NF厚度为0.6 mm时，NiCoP/NF膜电极的电池性能最佳。双进料方式下膜电极的电池性能显著优于单进料方式。电池在300 m A/cm2下持续运行200 h，电压与产氢速率分别稳定在2.5 V和1.26 mol/min左右，表明Ni CoP/NF膜电极的稳定性较好。[结论]本研究制备的Ni Co P/NF膜电极具备良好的催化活性，为开发高性能、低成本的水电解催化剂提供了新的思路和技术支持。
Abstract：[Objective] With the growing global demand for clean energy and increasing environmental awareness, developing efficient, stable, and low-cost catalysts for hydrogen production via water electrolysis has become crucial for the development of the hydrogen energy industry. [Method] Nickel cobalt phosphide(NiCoP) layer was loaded onto a nickel foam(NF) substrate by combining hydrothermal reaction, high-temperature calcination, and phosphidation, forming a NiCoP/NF composite membrane electrode. The morphology and structure of the NiCoP/NF membrane electrode were characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD), and nitrogen adsorption–desorption test. The effects of different factors on the oxygen evolution reaction(OER) and hydrogen evolution reaction(HER) activity as well as the battery performance of the electrode were studied through electrochemical measurements. [Result] The NiCoP/NF membrane electrode exhibited optimal OER and HER performance when the NaH2 PO2·H_2O concentration was 125 g/L. The best battery performance was achieved using a 0.6 mm-thick NF as the substrate. The battery performance under dual-feed mode was significantly better than that under single-feed mode. The battery maintained stable operation for 200 h at 300 mA/cm2, with voltage and hydrogen production rate stabilizing around 2.5 V and 1.26 mol/min, respectively, indicating good stability of the Ni CoP/NF membrane electrode. [Conclusion] The prepared NiCoP/NF membrane electrode exhibits excellent catalytic activity, providing new insights and technical support for the development of high-performance and low-cost water electrolysis catalysts.
