摘要

合理设计高效的析氧非贵金属催化剂是推进水裂解制氢的关键。在本研究中，在泡沫镍（NF）上原位合成了一种核壳结构的电催化剂NiFe-LDH/Co/C@NF，其特征是NiFe-LDH纳米片生长在多孔且富含缺陷的Co/C纳米球表面。该电催化剂具有较高的电化学活性表面积（ECSA），双层电容（Cdl）为81.84 mF cm−2，有效地暴露了丰富的活性位点。在电流密度为50毫安厘米−2的OER下，它还提供了仅244毫伏的低过电位。此外，电催化剂表现出优异的催化稳定性，在100毫安厘米−2的电流密度下保持100小时以上的高性能。

NiFe-LDH/co/C@NF composite electrocatalyst with enhanced oxygen evolution reaction performance

The rational design of efficient non-precious metal catalysts for the oxygen evolution reaction (OER) is essential to advancing hydrogen production via water splitting. In this study, a core-shell structured electrocatalyst, NiFe-LDH/Co/C@NF, is in situ synthesized on nickel foam (NF), featuring NiFe-LDH nanosheets growing on the surface of porous and defect-rich Co/C nanospheres. This electrocatalyst possesses high electrochemical active surface area (ECSA), with a double-layer capacitance (C_dl) of 81.84 mF cm⁻², effectively exposing abundant active sites. It also delivers a low overpotential of only 244 mV at a current density of 50 mA cm⁻² for OER. Furthermore, the electrocatalyst demonstrates exceptional catalytic stability, maintaining high performance for over 100 h at a current density of 100 mA cm⁻².

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
