Cooperative CO2-to-ethanol conversion via enriched intermediates at molecule–metal catalyst interfaces
2020
Overview
Electrochemical conversion of CO
2
into liquid fuels, powered by renewable electricity, offers one means to address the need for the storage of intermittent renewable energy. Here we present a cooperative catalyst design of molecule–metal catalyst interfaces with the goal of producing a reaction-intermediate-rich local environment, which improves the electrosynthesis of ethanol from CO
2
and H
2
O. We implement the strategy by functionalizing the copper surface with a family of porphyrin-based metallic complexes that catalyse CO
2
to CO. Using density functional theory calculations, and in situ Raman and operando X-ray absorption spectroscopies, we find that the high concentration of local CO facilitates carbon–carbon coupling and steers the reaction pathway towards ethanol. We report a CO
2
-to-ethanol Faradaic efficiency of 41% and a partial current density of 124 mA cm
−2
at −0.82 V versus the reversible hydrogen electrode. We integrate the catalyst into a membrane electrode assembly-based system and achieve an overall energy efficiency of 13%.
