Abstract

In the context of the global greenhouse effect and energy scarcity, it is of great significance to convert carbon dioxide (CO₂) into value-added fuels and chemicals through renewable electricity. Cu-based catalysts have been challenging for producing C₁ and C₂₊ high-value chemicals in electrochemical CO₂ reduction reaction (CO₂RR). Plenty of research groups have engaged in the development of Cu-based catalysts with high activity, selectivity, and stability. This review comprehensively summarizes the recent progress in engineering Cu-based catalysts for CO₂RR, with a detailed understanding of the reaction mechanism, catalyst design, and product selectivity. Besides, the strategies aiming at improving the stability of Cu-based catalysts and advancements in CO₂RR electrolyzers are addressed. Finally, the future important research directions of Cu-based catalysts in practical CO₂RR are prospected.

Key words： CO₂RR; Cu-based catalysts; Catalyst design; CO₂RR electrolyzers
