Productively harnessing CO 2 as a reactant is of practical interest due to addressing the dual pressures of resource sustainability and environmental sustainability. Electrochemical CO 2 reduction (ECR) offers a promising approach for driving the chemical transformation of CO 2 by exploiting green renewably generated electricity at (near) room temperature and ambient pressure, facilitating a sustainable, low-carbon footprint future. In this work, we provide a comprehensive and timely review of the various avenues that have been developed to date to modulate product selectivity, stability, and efficiency toward C 2+ using Cu-based electrocatalysts. We discuss how the electrocatalyst structure can be effectively designed in order to boost performance. Special attention is paid to some of the critical intermediate species that shed light on CO 2 reduction paths. We will also discuss the application of in situ and operando spectroscopy, along with computational techniques, that help to improve our fundamental understanding of ECR. Finally, development opportunities and challenge in the conversion of CO 2 into multi-carbon fuels by Cu-based electrocatalysts are presented.
