降低大气中二氧化碳(CO2)浓度以实现碳中和,已成为环境科学与可持续发展领域一项紧迫的全球性挑战。利用电催化CO2还原反应(electrocatalytic CO2 reduction reaction, ECRR)可制备高附加值化学品与燃料,为减少CO2排放、将可再生电能转化为化学能提供了一种极具前景的方法。金属有机框架(metal-organic frameworks, MOFs)是一种具有潜力的ECRR催化剂,得益于其多孔、结构清晰且可调节的框架结构,这有利于CO2富集,并有助于探索结构-性能之间关系和催化反应机理。基于含氮杂环配体MOFs材料因其独特的物理化学特性在ECRR研究中备受关注,这些特性包括灵活多样的框架、丰富的活性位点和高稳定性等。本综述系统评述了基于含氮杂环配体MOFs材料的相关性质和表征手段,并按含氮杂环结构类别,即咪唑基、吡唑基、三唑基、四唑基等,归纳了含氮杂环配体MOFs材料在ECRR领域的最新研究进展。最后,剖析了当前制约该类MOFs在ECRR实际应用方面的关键挑战,包括本征导电性不足、在长时间运行条件下结构和电化学稳定性问题、电解槽系统集成以及催化反应过程中动态结构演变导致的机理模糊等,并在此基础上对未来研究方向进行了展望。

Achieving carbon neutrality through reducing amounts of atmospheric carbon dioxide (CO2) has emerged as an urgent global challenge in the fields of environmental science and sustainable development. Among the emerging mitigation strategies, electrocatalytic CO₂ reduction reaction (ECRR) stands out for its capacity to convert CO₂ into high-valued chemicals or energy-dense fuels, providing a promising approach for reducing CO₂ emissions and converting renewable electric energy into chemical energy. Metal-organic frameworks (MOFs) represent a promising class of catalysts for ECRR, owing to their intrinsic structural advantages—including well-defined porosity and atomic-level structural tunability—which collectively enhance CO₂ mass transport and adsorption, and enable systematic investigation of structure-activity relationship as well as reaction mechanism. In particular, MOFs constructed from nitrogen-containing heterocyclic ligands have garnered remarkable research interests, attributed to their superior features such as structural flexibility, abundant catalytic sites and suitable stability. This review outlines the fundamental physicochemical properties and advanced characterization techniques for the nitrogen-containing heterocyclic ligand-based MOFs. Then recent advances in the application of such MOFs to ECRR were summarized categorizing by the nitrogen-containing moieties, namely imidazolyl-, pyrazolyl-, triazolyl- and tetrazolyl-based ligands. Finally, this review analyzed the critical challenges impeding the practical application of nitrogen-containing heterocyclic ligand-based MOFs in ECRR, including intrinsic electronic conductivity limitations, structural and electrochemical stability under prolonged operational conditions, integration of electrolyze systems and mechanistic ambiguities arising from dynamic structural evolution during the ECRR. On this basis, prospects for future research directions are presented.
