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.
