Recent advances and future perspectives of metal-organic frameworks as efficient electrocatalysts for CO2 reduction

The conversion of carbon dioxide (CO 2 ) to the reduced chemical compounds offers substantial environmental benefits through minimizing the emission of greenhouse gas and fostering sustainable practices. Recently, the unique properties of metal-organic frameworks (MOFs) make them attractive candidates for electrocatalytic CO 2 reduction reaction (CO 2 RR), providing many opportunities to develop efficient, selective, and environmentally sustainable processes for mitigating CO 2 emissions and utilizing CO 2 as a valuable raw material for the synthesis of fuels and chemicals. Here, the recent advances in MOFs as efficient catalysts for electrocatalytic CO 2 RR are summarized. The detailed characteristics, electrocatalytic mechanisms, and practical approaches for improving the electrocatalytic efficiency, selectivity, and durability of MOFs under realistic reaction conditions are also clarified. Furthermore, the outlooks on the prospects of MOF-based electrocatalysts in CO 2 RR are provided. 将二氧化碳(CO 2 )转化为其还原型化合物不仅能够显著减少温室气体的排放, 还为推动可持续发展提供了重要机遇. 近年来, 金属有机框架(MOFs)材料凭借其独特的性质成为电催化CO 2 还原反应 (CO 2 RR)的理想候选材料, 为开发高效、选择性强且环境友好的CO 2 减排工艺提供了诸多机会, 同时有望将CO 2 转化为高价值燃料和化学品原料. 本文综述了MOFs作为CO 2 RR高效电催化剂的最新研究进展, 详尽阐述了其催化特性、电催化机制及在实际反应条件下提高MOFs电催化效率、选择性和和耐久性的实用方法. 此外, 还对基于MOF的电催化剂在CO 2 RR中的应用前景进行了展望.
