近日，华中科技大学王春栋团队研究了为电催化析氢应用定制反钙钛矿碳化物。2025年12月24日出版的《结构化学》杂志发表了这一最新研究成果。

开发高效且成本低廉的电解水催化剂对于推动可持续能源技术发展至关重要。反钙钛矿碳化物凭借其组分可调性与低成本优势，已成为极具潜力的候选材料。

研究组合成了一系列Ni_3-xCo_xInC反钙钛矿碳化物，其中具有优化镍钴比例的样品在析氢反应中展现出优异的电催化性能。该催化剂在10 mA·cm^-2电流密度下仅需140 mV过电位，并在长期运行条件下保持良好稳定性。其性能提升归因于镍钴原子间的协同作用，以及合成过程中引入的碳缺陷密度增加，二者共同促进了反应中间体的高效吸附与脱附。该研究不仅为电解水催化剂开发提供了新视角，也拓展了多金属碳化物及金属间化合物在电化学能量转换领域的应用范围。

Abstract: The development of efficient and cost-effective electrocatalysts for water splitting is crucial for advancing sustainable energy technologies. Antiperovskite carbides, with their compositional tunability and low cost, have emerged as promising candidates. In this work, a series of Ni3-xCoxInC antiperovskite carbides were synthesized, among which the sample with the optimized Ni/Co ratio exhibited impressive electrocatalytic activity toward the hydrogen evolution reaction (HER). Specifically, the catalyst achieved a low overpotential of 140 mV at 10 mA cm-2, together with robust durability under prolonged operating conditions. The enhanced HER performance is attributed to the synergistic interaction between Ni and Co atoms, as well as the increased density of carbon defects introduced during synthesis, which together facilitate favourable adsorption and desorption of reaction intermediates. This study not only offers a new perspective for the development of water-splitting catalysts but also expands the application scope of polymetallic carbides and intermetallic compounds in electrochemical energy conversion.
