Electrocatalytic generation of C2 and C3 compounds from carbon dioxide on a cobalt complex-immobilized dual-film electrode

Abstract

The electrocatalytic reduction of CO₂ on a Prussian blue–polyaniline dual film electrode on platinum including immobilized 2-hydroxy-1-nitrosonaphthalene-3,6-disulfonatocobalt(II) in aqueous solution leads to the formation of lactic acid, ethanol, acetone and methanol at a low overpotential (–0.6 V vs. standard calomel electrode) under ambient conditions.
