SELECTIVE PORPHYRIN-CATALYZED ELECTROCHEMICAL REDUCTION OF CO2 INTO CO, IN PARTICULAR IN WATER

摘要

The present invention relates to the use of complexes of water soluble porphyrins of formula (I). The present invention relates to water soluble porphyrins of formula (I), wherein R₁ to R₁₁ and R₁′ to R₈′ are as defined in claim 1, their iron complexes, use thereof as catalysts for the selective electrochemical reduction of CO₂ into CO, electrochemical cells comprising them, and methods for reducing electrochemically CO₂ into CO using said complexes or said electrochemical cells, thereby producing CO or syngas.;
