Boosting electrocatalytic CO₂-to-ethanol production via asymmetric C-C coupling.

ABSTRACT: Electroreduction of carbon dioxide (CO₂) into multicarbon products provides possibility of large-scale chemicals production and is therefore of significant research and commercial interest. However, the production efficiency for ethanol (EtOH), a significant chemical feedstock, is impractically low because of limited selectivity, especially under high current operation. Here we report a new silver-modified copper-oxide catalyst (dCu₂O/Ag_2.3%) that exhibits a significant Faradaic efficiency of 40.8% and energy efficiency of 22.3% for boosted EtOH production. Importantly, it achieves CO₂-to-ethanol conversion under high current operation with partial current density of 326.4 mA cm^-2 at -0.87 V vs reversible hydrogen electrode to rank hig
