Electrochemical CO 2 Reduction toward Acetate/Acetic Acid

Electrochemical CO 2 reduction is a promising approach for a sustainable economy, as it converts CO 2 into valuable products. However, converting CO 2 into multicarbon products specifically, toward acetate as the major product, is challenging due to high energy barriers and low CO* coverage on the catalyst surface. This leads to the primary products being ethylene and ethanol instead. While electrochemical approaches for converting CO to acetate are gaining attention, accomplishing this directly through CO 2 reduction remains a substantial challenge. This mini review summarizes recent advancements in catalyst design and experimental strategies to convert CO 2 into acetate. We discuss various strategies, innovations in catalyst design, and electrochemical setups to enhance selectivity and efficiencies.
