Recent advances in Cu-based catalysts for electroreduction of carbon dioxide

Abstract

Electrochemical CO₂ reduction reaction (CO₂RR) is an important approach implemented in converting CO₂ to valuable products, achieving energy and environmental sustainability. Recently, Cu-based electrocatalysts for CO₂ conversion have attracted immense attention due to their fantastic ability to catalyze CO₂ to various products with high activity and selectivity. This review summarizes the recent advances in the rational design of Cu-based electrocatalysts used for CO₂RR, including tunable structure and size, exploitation of advanced supports, and composition engineering of Cu-based oxides and alloys. Meanwhile, the stability, activity, catalytic performance, and mechanism are also highlighted. Finally, the application prospects and challenges for Cu-based electrocatalysts are summarized to satisfy the need for advanced electrocatalysts for CO₂RR.
