Two-dimensional materials: synthesis and applications in the electro-reduction of carbon dioxide

Abstract

The emission of CO₂ has become an increasingly prominent issue. Electrochemical reduction of CO₂ to value-added chemicals provides a promising strategy to mitigate energy shortage and achieve carbon neutrality. Two-dimensional (2D) materials are highly attractive for the fabrication of catalysts owing to their special electronic and geometric properties as well as a multitude of edge active sites. Various 2D materials have been proposed for synthesis and use in the conversion of CO₂ to versatile carbonous products. This review presents the latest progress on various 2D materials with a focus on their synthesis and applications in the electrochemical reduction of CO₂. Initially, the advantages of 2D materials for CO₂ electro-reduction are briefly discussed. Subsequently, common methods for the synthesis of 2D materials and the role of these materials in the electrochemical reduction of CO₂ are elaborated. Finally, some perspectives for future investigations of 2D materials for CO₂ electro-reduction are proposed.
