Electrocatalytic carbon dioxide (CO) reduction to valuable chemical compounds is a sustainable technology with enormous potential to facilitate carbon neutrality by transforming intermittent energy sources into stable fuels. Among various electrocatalysts, metal-organic frameworks (MOFs) have garnered increasing attention for the electrochemical CO reduction reaction (CORR) owing to their structural diversity, large surface area, high porosity and tunable chemical properties. Ligands play a vital role in MOFs, which can regulate the electronic structure and chemical environment of metal centers of MOFs, thereby influencing the activity and selectivity of products. This feature article discusses the strategies for the rational design of ligands and their impact on the CORR performance of MOFs to establish a structure-performance relationship. Finally, critical challenges and potential opportunities for MOFs with different ligand types in the CORR are mentioned with the aim to inspire the targeted design of advanced MOF catalysts in the future to achieve efficient electrocatalytic CO conversion.
将电催化二氧化碳（CO）还原为有价值的化合物是一项可持续技术，通过将间歇性能源转化为稳定燃料，在促进碳中和方面具有巨大潜力。在各种电催化剂中，金属有机框架（MOF）因其结构多样性、大表面积、高孔隙率和可调节的化学性质，在电化学CO还原反应（CORR）中受到越来越多的关注。配体在MOF中起着至关重要的作用，它可以调节MOF金属中心的电子结构和化学环境，从而影响产物的活性和选择性。这篇专题文章讨论了配体合理设计的策略及其对MOF的CORR性能的影响，以建立结构-性能关系。最后，提到了不同配体类型的MOF在CORR中面临的关键挑战和潜在机遇，旨在激发未来先进MOF催化剂的靶向设计，以实现高效的电催化CO转化。
