Efficient electrocatalytic CO2 reduction with a molecular cofacial iron porphyrin dimer

A cofacial iron tetraphenyl porphyrin dimer, , bio-inspired by the Ni-Fe containing metalloenzyme, carbon monoxide dehydrogenase (CODH), efficiently and selectively catalyses the electrochemical reduction of CO2 to CO in DMF/10% H2O solution at the electro-generated Fe(0)(por) species with high Fara...

Zusammenfassung:A cofacial iron tetraphenyl porphyrin dimer, , bio-inspired by the Ni-Fe containing metalloenzyme, carbon monoxide dehydrogenase (CODH), efficiently and selectively catalyses the electrochemical reduction of CO2 to CO in DMF/10% H2O solution at the electro-generated Fe(0)(por) species with high Faradic efficiency (95%) and TOF (4300 s(-1)) at a moderate overpotential, η = 0.66 V.
