Today the viability of CO2R technology is limited by carbonate formation via the reaction of reactant CO2 with hydroxides and the energy cost incurred to regenerate the reactant. In this Review, we analyse the literature on four emerging high single pass CO2 conversion approaches: CO2 regeneration from carbonate, CO2R in acidic media, cascade CO2R-COR and CO2R direct from a capture liquid. We analyse each system, describe the challenges associated with each pathway and outline future research directions towards the goal of ensuring that CO2R is viable and thus scalable.

One challenge for efficient electrochemical reduction of carbon dioxide (CO2) is that the gas is hydrophobic, but many of its desirable reactions require water (H2O). García de Arquer et al. addressed this problem by combining a copper electrocatalyst with an ionomer assembly that intersperses sulfonate-lined paths for the H2O with fluorocarbon channels for the CO2. The electrode architecture enables production of two-carbon products such as ethylene and ethanol at current densities just over an ampere per square centimeter.

Great seminar here at ICFO from H.P. Iglesias van Montfort (TU DELFT).

Two lab members presented their work at the University of Girona and spent the day in the beautiful city.

After eating milanesa and tapas, we took a nice beach walk in Castelldefels, Barcelona.
