A method reducing carbon dioxide to one or more organic products may include steps (A) to (E). Step (A) may introduce an anolyte to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce a catholyte and carbon dioxide to a second compartment of the electrochemical cell. Step (C) may oxidize an indium cathode to produce an oxidized indium cathode. Step (D) may introduce the oxidized indium cathode to the second compartment. Step (E) may apply an electrical potential between the anode and the oxidized indium cathode sufficient for the oxidized indium cathode to reduce the carbon dioxide to a reduced product.
