Two‐Dimensional Electrocatalysts for Efficient Reduction of Carbon Dioxide

Two-dimensional (2D) materials are attractive catalysts for the electrochemical reduction of carbon dioxide reaction (eCO2 RR) 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 eCO2 RR 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 eCO2 RR are reviewed. Prospects and challenges of applications of 2D catalysts for the eCO2 RR on an industrial scale are highlighted.
