Abstract

In this work, the novel FeNi-LDH/NF and (Fe-Ni)O_x/NF were prepared using facile hydrothermal and calcination methods. The electrocatalyst FeNi-LDH/NF ((Fe-Ni)O_x/NF) exhibits excellent HER catalytic activity, and produced an overpotential of 147 (210) mV at 10 mA cm⁻² with a small Tafel value of 97 (100) mV dec⁻¹ in 1.0 M KOH electrolyte. Due to the high-density active centers exposed on the surface of FeNi-based hydroxides, their electrical conductivity, and the synergistic effect between the metals, the catalytic activity of FeNi-based hydroxides is superior to that of FeNi-based oxides. The overall experimental findings showcase a feasible approach for exploring the potential of the nonprecious metal-based FeNi-LDH/NF ((Fe-Ni)O_x/NF) nanoelectrocatalyst towards alkaline HER.

铁镍基催化剂作为析氢反应的高效电催化剂

本文采用水热法和煅烧法制备了新型FeNi-LDH/NF和（Fe-Ni）Ox/NF。电催化剂FeNi-LDH/NF (Fe-Ni)Ox/NF)表现出优异的HER催化活性，在10 mA cm−2下产生147 (210)mV的过电位，在1.0 M KOH电解质下产生97 (100)mV dec−1的过电位。由于feni基氢氧化物表面暴露的高密度活性中心、其导电性以及金属间的协同作用，使得feni基氢氧化物的催化活性优于feni基氧化物。整体实验结果为探索非贵金属基FeNi-LDH/NF （(Fe-Ni)Ox/NF）纳米电催化剂在碱性HER中的潜力提供了一种可行的方法。图形抽象

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
