Incorporation of carbon into metal lattices yields transition metal carbides (TMCs) with properties quite different from their parent metals and corresponding metal oxides. In this short review, we summarize the recent progress on employing TMCs as active catalysts for hydrogen (H₂) production, namely by the water-gas-shift reaction, methanol reforming, and the hydrogen evolution reaction in water electrolysis. Special interest is put on comparing the catalytic properties of TMCs with traditional metal oxide catalysts to understand the superior activities of TMCs in H₂-production reactions.

过渡金属碳化物催化剂制氢进展：挑战与机遇

将碳掺入金属晶格中会产生过渡金属碳化物（TMC），其性质与其母金属和相应的金属氧化物完全不同。在这篇简短的综述中，我们总结了使用TMC作为生产氢气（H ₂）的活性催化剂的最新进展，即通过水煤气变换反应，甲醇重整和水电解中的氢气释放反应。特别关注将TMC与传统金属氧化物催化剂的催化性能进行比较，以了解TMC在H _2生成反应中的优越活性。
