Electrochemical Conversion of Carbon Dioxide to Methanol with Use of Enzymes as Biocatalysts

Article abstract of DOI:10.1246/cl.1993.1631

Electrolysis of carbon dioxide-saturated phosphate buffer solution (pH 7) in the presence of formate dehydrogenase and methanol dehydrogenase as electrocatalysts together with methylviologen as an electron relay yielded formaldehyde and methanol as the reduction products of carbon dioxide under suitable electrolysis conditions, and the use of pyrrolo-quinoline quinone in place of methylviologen as the electron relay afforded selective reduction of carbon dioxide to methanol.
