Abstract
The present invention relates to porphyrins of formula (I): wherein R1 to R6, R1′ to R6′, 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.
