Alkaline electrolysis using CuO x cathode for the conversion of carbon dioxide into liquid fuels

Electrochemical reduction of CO 2 is an effective method for storing intermittent renewable energy. This could result in fuel additives and chemical feedstocks such as alcohols. A challenge of electrochemical alcohol production is the transfer of electrons and protons, as well as the formation of C–C bonds. As of now, copper-based materials are the most commonly used and effective catalysts. Although CuO x is considered a promising catalyst for electrochemical CO 2 reduction reactions (CO2RR), significant improvements in product selectivity are still needed. This paper presents some results obtained using copper oxide as a cathode, combined with 33
