Electrochemical CO₂ Reduction to CO

CO2 + 2H+ + 2e → CO + H2O

نظرة عامة

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.
