| Abstract | Transforming carbon dioxide (CO2) into products using renewable electricity is a crucial and captivating quest for a green and circular economy. Compared with commonly used alkali electrolytes, acidic media for electrocatalytic CO2 reduction (CO2RR) boasts several advantages, such as high carbon utilization efficiency, high overall energy utilization rate, and low carbonate formation, making it a compelling choice for industrial applications. However, the acidic CO2RR also struggles with formidable hurdles, encompassing the fierce competition with the hydrogen evolution reaction, the low CO2 solubility and availability, and the suboptimal performance of catalysts. This review provides a comprehensive overview of the CO2RR in acidic media. By elucidating the underlying regulatory mechanism, we gain valuable insights into the fundamental principles governing the acidic CO2RR. Furthermore, we examine cutting-edge strategies aimed at optimizing its performance and the roles of reactor engineering, especially membrane electrode assembly reactors, in facilitating scalable and carbon efficient conversion. Moreover, we present a forward-looking perspective, highlighting the promising prospects of acidic CO2RR research in ushering us towards a carbon-neutral society. |
