Two‐Dimensional Electrocatalysts for Efficient Reduction of Carbon Dioxide

Two‐dimensional (2D) materials are attractive catalysts for the electrochemical reduction of carbon dioxide reaction (eCO2RR) by virtue of their tunable atomic structures, abundant active sites, enhanced conductivity, suitable binding affinity to carbon dioxide and/or reaction intermediates, and intrinsic scalability. Herein, recent advances in 2D catalysts for the eCO2RR are reviewed. Structural features and properties of 2D materials that contribute to their advanced electrocatalytic properties are summarized, and strategies for enhancing their activity and selectivity for the eCO2RR are reviewed. Prospects and challenges of applications of 2D catalysts for the eCO2RR on an industrial scale are highlighted. Trading up: If powered by renewable electricity, electrochemical carbon dioxide reduction provides an attractive mechanism to convert this cheap and abundant greenhouse gas into value‐added chemicals. Two‐dimensional materials are attractive catalysts for this reaction because of their tunable atomic structures, abundant active sites, enhanced conductivity, suitable binding affinity to CO2 or reaction intermediates, and intrinsic scalability.
