Abstract

Copper has received significant attention for decades as electrode material for the electrochemical reduction of carbon dioxide (CO₂RR) because of its capability to form multi-carbon products (C₂₊). However, despite substantial research, CO₂RR with Cu-based electrocatalysts has yet to be commercialized. Understanding the physical and chemical changes of the catalyst surface and the dynamics of the electrochemical interface during CO₂RR is key to improve the activity and selectivity. This review article focuses on recent studies that provide important insights of the surfaces and interfaces during reduction using ex-situ, in-situ and operando characterization techniques.
