Relatively few solution electrocatalysts for CO2 reduction in aqueous solutions are
reported. However to be sustainable, electrocatalytic CO2 reduction is likely to be coupled to water
oxidation in a complete device. Here we report a water-soluble Mn polypyridyl complex for the
electrocatalytic reduction of CO2 to CO. This complex shows activity across a broad pH range and an
excellent selectivity at pH 9 (3.8:1, CO:H2). Cyclic voltammetry indicates activity across a range of
different electrode materials (Boron doped diamond, glassy carbon and Hg/Au amalgams).
