Nanowerk  August 18, 2023 Potentiodynamic methods that induce structural changes in Cu catalysts for the electrochemical reduction of CO2 (CO2RR) have been identified as a promising strategy for steering the catalyst selectivity towards the generation of multi-carbon products. In the current approaches, active species are created via a sequential Cu oxidation–reduction process. Researchers in Germany have shown that low-coordinated Cu surface species form spontaneously near the onset of CO2 electrocatalytic reduction. This process started by CO-induced Cu nanocluster formation in the initial stages of the reaction, led to irreversible surface restructuring that persisted over a wide potential range. On subsequent […]
