Enhanced formation of ethylene and alcohols at ambient temperature and pressure in electrochemical reduction of carbon dioxide at a copper electrode

Abstract

In the electroreduction of CO₂ at a copper cathode in aqueous solution at ambient temperature and pressure the faradaic yield of C₂H₄ amounted to 48%, and appreciable amounts of EtOH and PrⁿOH were formed; the selectivity of the products depends strongly upon the electrolytes.
