A path forward to efficient CO2 electrolysis

Dr. F. Pelayo Garcia de Arquer
ICFO Barcelona

The electroreduction of CO2 to chemicals has the potential to enable a transition from fossil to renewable sources in the vast chemical industry - for example to produce clean fuels and materials for manufacturing. The technoeconomic viability of the CO2 reduction (CO2R) technology depends on achieving sufficient product selectivity, productivity (or current density), energy efficiency, and stability. I will present recent advances that, based on the manipulation of catalyst environment, achieve CO2R to key multicarbon chemicals such as ethylene, ethanol, and propanol at high selectivity and productivity. With these increasing performance metrics, a crucial limiting factor in the CO2R technology is CO2 reactant loss - a result of rapid carbonate formation in alkaline and neutral electrolytes - which brings additional energy penalties. To conclude, I will provide an overview of some emerging strategies to address this challenge.
