Abstract: CO2 capture and conversion have garnered worldwide attention in view of the objective of sustainable development and carbon neutrality. Recently, ionic liquid-functionalized metal−organic frameworks (MOFs) or covalent−organic frameworks (COFs) (MOFs/COFs) offer a rising platform for the effective CO2 separation from specific gas mixture and CO2 conversion into value-added chemicals. Benefiting from the synergistic effect offered by ILs and MOFs/COFs, IL-MOFs/COFs exhibit better exceptional adsorption/catalytic performance than pristine MOFs/COFs or ILs. Herein, the review intends to establish a primary database for the recently emerging IL-MOFs/COFs in CO2 capture and conversion, covering the functionalization strategies, interaction between ILs and MOFs/COFs, and the representative applications, aiding in the rational design and optimization of novel IL-MOFs/COFs with exceptional properties for real-world application. Along this line, CO2 capture from different systems (CO2/N2, CO2/CH4, and CO2/C2H2) and further conversion into multiproducts (cyclic carbonate, hydrocarbon, alcohol, and others), along with the mechanism insight into ILs and MOFs/COFs in such adsorption/catalytic processes are summarized and discussed. Furthermore, the challenges and prospects of IL-MOFs/COFs in such emerging and topical fields have been elaborated.
鉴于可持续发展和碳中和的目标，二氧化碳捕集与转化引起了全世界的关注。近年来，离子液体功能化金属有机骨架（MOFs）或共价有机骨架（COFs） （MOFs/COFs）为从特定气体混合物中有效分离CO2和将CO2转化为增值化学品提供了一个新兴的平台。得益于IL-MOFs/COFs的协同效应，IL-MOFs/COFs表现出比原始MOFs/COFs或ILs 更好的特殊吸附/催化性能。在此，本文将对近年来出现的IL-MOFs/COFs在CO2捕集与转化中的应用进行综述，包括功能化策略、IL-MOFs/COFs与IL-MOFs/COFs之间的相互作用以及具有代表性的应用，为IL-MOFs/COFs的合理设计和优化提供依据。沿着这条线，总结和讨论了不同体系（CO2/N2， CO2/CH4和CO2/C2H2）的CO2捕获和进一步转化为多产物（环碳酸盐，碳氢化合物，醇等），以及 ILs和MOFs/COFs在这种吸附/催化过程中的机理。此外，还阐述了 IL-MOFs/COFs在这些新兴和热门领域的挑战和前景。
