Abstract
AbstractThe use of green renewable energy to convert carbon dioxide (CO2) into valuable chemicals and fuels through CO2 electrolysis technology (also known as electrochemical CO2 reduction reaction, eCO2RR) is an advantageous technology, which could greatly aid the global carbon‐neutral goal. Although progress has been made in alkaline/neutral media, low carbon conversion efficiency to target products, carbonate/bicarbonate salt precipitation, and blockage of electrode holes caused by CO2 are not conducive to industrial applications. Acidic media could address these issues; however, in these conditions, there are other challenges that need to be addressed, such as hydrogen evolution, poor tolerance of electrocatalysts, and electrolysers. This review discusses recent advances in industrial‐level acidic CO2 electrolysis, including reaction mechanisms, electrocatalysts, and device design, aiming to promote its commercialization. In addition, a comprehensive evaluation strategy of an acidic eCO2RR system is proposed, and perspectives are provided based on related discussion.
