Electroreduction of Carbon Dioxide By Cu, Cu/Ti and Cu/Ni Flag Electrodes in Aqueous Media

The reduction efficiency of CO₂ on copper is investigated by examining catalyst deposition techniques and electrodes substrates. It was observed that for the same current density the Cu/Ni flag electrode requires less voltage that Cu foil and Cu/Ti flag electrode.  Copper-based electrocatalysts can be prepared that will improveCO₂ electroreduction.
