Electrochemical CO₂ Reduction to CO

CO₂ + 2H⁺ + 2e⁻ → CO + H₂O

अवलोकन

Electrochemical reduction of CO₂ at a metal cathode can selectively produce CO (on Au/Ag), formate (on Sn/Pb/Bi), or hydrocarbons (on Cu). CO + H₂ (syngas) can then be converted to fuels via Fischer-Tropsch synthesis. This carbon capture and utilization (CCU) approach could close the carbon cycle using renewable electricity.
