EnglishWe describe the realization of an electrolyzer for the electroreduction of CO2 to useful hydrocarbons and carboxylates such as CH4, C2H4, and HCOO-. The device uses a molecular copper phthalocyanine-based cathode, an anion exchange membrane, and a nanostructured Pd@Ti anode. The key advantage of this device is the exploitation of anodic alcohol oxidation instead of water oxidation. The lower operating cell potential due to the presence of ethanol leads to a net reduction in energy consumption, from 130 kWh to 77 kWh (per kg of hydrocarbon product mixture), in comparison to the cell operating with oxygen evolution.
