Description
Summary:The electrochemical reduction process is one of the most promising approaches to both efficiently remove the important greenhouse gas CO 2 and convert it to chemical products of high value. However, in addition to the configuration of electrochemical cells, electrocatalysts are main factors affecting key performances in electrochemical CO 2 reduction reactions. Recently, studies have been conducted to investigate the roles of metal‐based electrocatalysts and improve their performances through alloying, oxidization, and microstructural modulations. This review comprehensively discusses and analyzes the developments made in such metal‐based electrocatalyst studies and presents the advancements of important metals for use in electrochemical CO 2 reduction processes. The relationships between the electrodes' microstructure, chemistry, and efficiency in CO 2 conversion are also compared and discussed.
