Abstract
Methods and cells are provided for electrochemically oxidizing methane to formate, in which methane supplied to an alkaline aqueous anolyte medium comprising hydroperoxyl anions is brought into contact with an oxidation catalyst anode. The oxidation catalyst may include CuFe oxide catalytic centres supported on a nickel substrate. An anodic current supplied to the oxidation catalyst in the anolyte medium electrolytically oxidizes methane to formate.
Claims7
A method for electrochemically oxidizing methane to formate, comprising, in an electrolytic cell:
- providing a methane supply to an alkaline aqueous anolyte medium comprising hydroperoxyl anions, wherein the alkaline aqueous anolyte medium is in contact with an oxidation catalyst anode, wherein the oxidation catalyst anode comprises CuFe oxide catalytic centres supported on a nickel substrate;
- and,
- supplying an anodic current to the oxidation catalyst anode in the alkaline aqueous anolyte medium, to electrolytically oxidize methane to formate in an anodic oxidation reaction.
