A hydrophobic Cu/Cu₂O sheet catalyst for selective electroreduction of CO to ethanol.

ABSTRACT: Electrocatalytic reduction of carbon monoxide into fuels or chemicals with two or more carbons is very attractive due to their high energy density and economic value. Herein we demonstrate the synthesis of a hydrophobic Cu/Cu₂O sheet catalyst with hydrophobic n-butylamine layer and its application in CO electroreduction. The CO reduction on this catalyst produces two or more carbon products with a Faradaic efficiency of 93.5% and partial current density of 151 mA cm^-2 at the potential of -0.70 V versus a reversible hydrogen electrode. A Faradaic efficiency of 68.8% and partial current density of 111 mA cm^-2 for ethanol were reached, which is very high in comparison to all previous reports of CO₂/CO electroreduction with a total current density hi
