Enhanced Electrocatalytic CO2 Reduction at Lower Overpotentials Using Iron (III) Tetra(thienyl)porphyrin

Authors

Abstract

Iron(III) tetra(5,10,15,20-thienyl)porphyrin chloride (FeTThP) is introduced as a new CO2 reduction catalyst. The optical and electrochemical properties, as well as the CO2 reduction capabilities of FeTThP are directly compared to those of iron(III) tetra(5,10,15,20-phenyl)porphyrin chloride (FeTPP). Relative to FeTPP, the newly developed FeTThP achieves a higher TONCO, with comparable faradaic efficiency, using a much lower overpotential.
