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 interest, attributed to their superior features such as structural flexibility, abundant catalytic active 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 electrolyzer systems and mechanistic ambiguities arising from dynamic structural evolution during the ECRR. On this basis, prospects for future research directions are presented.
