【摘要】 电催化水解制氢被视为缓解不可再生能源消耗的有效途径之一，寻找高活性的析氢反应（HER）催化剂是当前研究热点。碳化钼（MoC或Mo₂C）因其低成本及类铂HER特性备受关注，但高温烧制导致的结构过度生长会削弱其活性。笔者综述了近年来碳化钼功能化修饰的研究进展。研究表明，通过构建不同纳米结构、离子掺杂及复合材料等手段能有效改变碳化钼的电子构型，其催化活性甚至可达到优于铂（Pt）的水平。最后对碳化钼的发展进行了总结与展望，旨在为碳化钼的持续优化提供参考与借鉴。更多还原

【Abstract】 Electrocatalytic water cracking for hydrogen production is considered to be one of the effective methods to reduce the consumption of non-renewable energy.Finding a hydrogen evolution reaction（HER） catalyst with high activity is a research hotspot at present.Molybdenum carbide（MoC or Mo₂C） has attracted much attention because of its low cost and platinum-like HER properties.However, the activity is weakened due to the excessive growth of the structure caused by high-temperature firing.This paper reviews the research on the functional modification of molybdenum carbide in recent years.It can be seen that the construction of different nanostructures, ion doping, and composite fabrication can effectively change the electronic configuration of molybdenum carbide, even superior to that of Pt.The development of molybdenum carbide is prospected, which can provide a reference for its continuous optimization.更多还原
