Abstract
Abstract The escalating concern regarding the release of CO 2 into the atmosphere poses a significant threat to the contemporary efforts in mitigating climate change. Amidst a multitude of strategies for curtailing CO 2 emissions, the electrochemical CO 2 reduction presents a promising avenue for transforming CO 2 molecules into a diverse array of valuable gaseous and liquid products, such as CO, CH 3 OH, CH 4 , HCO 2 H, C 2 H 4 , C 2 H 5 OH, CH 3 CO 2 H, 1‐C 3 H 7 OH and others. The mechanistic investigations of gaseous products (e. g. CO, CH 4 , C 2 H 4 , C 2 H 6 and others) broadly covered in the literature. There is a noticeable gap in the literature when it comes to a comprehensive summary exclusively dedicated to coherent roadmap for the designing principles for a selective catalyst all possible liquid products (such as CH 3 OH, C 2 H 5 OH, 1‐C 3 H 7 OH, 2‐C 3 H 7 OH, 1‐C 4 H 9 OH, as well as other C 3 ‐C 4 products like methylglyoxal and 2,3‐furandiol, in addition to HCO 2 H, AcOH, oxalic acid and others), selectively converted by CO 2 reduction. This entails a meticulous analysis to justify these approaches and a thorough exploration of the correlation between materials and their electrocatalytic properties. Furthermore, these insightful discussions illuminate the future prospects for practical applications, a facet not exhaustively examined in prior reviews.
