Abstract
Disclosed is a system and method for reducing carbon dioxide into a carbon based product. The system includes an electrochemical cell having a cathode region which includes a cathode and a non-aqueous catholyte; an anode region having an anode and an aqueous or gaseous anolyte; and an ion permeable zone disposed between the anode region and the cathode region. The ion permeable zone is at least one of (i) the interface between the anolyte and the catholyte, (ii) an ion selective membrane; (iii) at least one liquid layer formed of an emulsion or (iv) a hydrophobic or glass fiber separator. The system and method includes a source of energy, whereby applying the source of energy across the anode and cathode reduces the carbon dioxide and produces an oxidation product.
