Electrochemical CO reduction provides a clean and viable alternative for mitigating the environmental aspects of global greenhouse gas emissions. To date, the simultaneous goals of CO reduction at high selectivity and activity have yet to be achieved. Here, the importance of engineering both sides of the electrode-electrolyte interface as a rational strategy for achieving this milestone is highlighted. An emphasis is placed on researchers contributing to the design of solid electrodes based on metal-organic frameworks (MOFs) and electrolytes based on room-temperature ionic liquids (RTILs). Future research geared toward optimizing the electrode-electrolyte interface for efficient and selective CO reduction can be achieved by understanding the structure of newly designed RTILs at the electrified interface, as well as structure-activity relationships in highly tunable MOF platforms.
电化学 CO 还原为缓解全球温室气体排放的环境问题提供了一种清洁可行的替代方法。迄今为止，高选择性和活性 CO 还原的同时目标尚未实现。在此，强调了将电极-电解质界面的两侧工程化作为实现这一里程碑的合理策略的重要性。重点介绍了研究人员在基于金属有机框架（MOF）的固体电极设计和基于室温离子液体（RTIL）的电解质方面的贡献。通过了解在带电界面处新设计的 RTIL 的结构，以及在高度可调的 MOF 平台中的结构-活性关系，可以实现针对高效和选择性 CO 还原来优化电极-电解质界面的未来研究。
