Porphyrin molecular catalysts for selective electrochemical reduction of CO₂ into CO

摘要

The present invention relates to porphyrins of formula (I): wherein R¹ to R⁶, R^1′ to R^6′, X, X′ Y and Y′ are as described in claim 1. The invention also relates to complexes of said porphyrins with transition metals, in particular iron, preferably as Fe(III) or Fe(0) complex, and salts thereof, use thereof as catalysts for the selective electrochemical reduction of CO₂ into CO, electrochemical cells comprising said complexes, and a method for selectively reducing electrochemically CO₂ into CO using said complexes.;
