The covalent grafting of an Fe porphyrin on carbon nanotubes led to efficient electroreduction of CO2 into CO in water (pH 7.3). CO was obtained with high selectivity and turnover at 0.5 V overpotential. The grafting strategy may be further extended to various conductive and semi-conductive surfaces.
