1 Introduction Climate change, driven by the anthropogenic production of carbon dioxide (CO2), is one of the major challenges of our time. The electrochemical CO2 reduction reaction (eCO2RR) to value-added products is increasingly considered as an alternative synthetic process promoting the transition to a circular carbon economy.[1-3] Technological advances in small cells over the last decade aim toward eventual scalability to achieve economic viability for industrial-scale application.
