Abstract
The present invention describes an electrochemical system (1) to electrochemically reduce carbon monoxide (CO) into liquid methanol and gaseous H2, comprising an electrochemical cell with an anodic compartment with an anode (2) with a current collector (2A), at least a catalyst to electrochemically oxidize H2O, and a cathodic compartment with a cathodic electrolyte solution comprising the solvent (3), and a cathodic supporting electrolyte, the solvent (3) being water at basic pH of between 10.5 and 13.5, the reagent CO; a cathode (4) which comprises, on a current collector (4A) which is electrochemically inert, at least a cobalt molecular catalyst (4B) to electrochemically reduce CO into liquid methanol and the gas H2, a power supply (5) providing the energy necessary to trigger the electrochemical reactions involving the reagent.
