Abstract

The electrocatalytic CO2 reduction reaction (CO2RR) has garnered significant attention in recent years as a promising method for mitigating CO2 emissions and generating value‐added carbon‐neutral fuels. Electrolyte, a crucial component of the CO2RR device, exerts a profound influence on the electrocatalytic efficiency and product distribution of CO2RR. The utilization of solid‐state electrolytes is considered an innovative and effective strategy to address the shortcomings of liquid electrolytes, such as low solubility of CO2 in aqueous electrolytes, mixing of liquid products with electrolytes, and carbon loss due to carbonate crossover. This review first summarizes the development of electrolyzers and discusses the limitations of liquid electrolyte existing in electrocatalytic CO2RR systems. Then, the primary types and key performance indexes of solid‐state electrolytes are reviewed, highlighting their notable advantages for electrocatalytic CO2RR. Importantly, major applications of solid‐state electrolyte in electrocatalytic CO2RR research are enumerated. Finally, challenges and opportunities are proposed for future development of solid‐state electrolyte in electrocatalytic CO2RR technology.

电催化CO2还原用固态电解质研究进展

近年来，电催化二氧化碳还原反应（CO2RR）作为一种有前景的减少二氧化碳排放和产生增值碳中性燃料的方法受到了广泛关注。电解质是CO2RR装置的关键组成部分，对CO2RR的电催化效率和产物分布有着深远的影响。固体电解质的利用被认为是一种创新和有效的策略，可以解决液体电解质的缺点，例如CO2在水电解质中的溶解度低，液体产品与电解质混合以及碳酸盐交叉导致的碳损失。本文首先综述了电解槽的发展，并讨论了电催化CO2RR系统中存在的液体电解质的局限性。然后，综述了固态电解质的主要类型和关键性能指标，强调了它们在电催化CO2RR方面的显著优势。重要的是，列举了固态电解质在电催化CO2RR研究中的主要应用。最后，对电催化CO2RR技术中固态电解质的未来发展提出了挑战和机遇。
