Water-Assisted Highly Efficient Photocatalytic Reduction of CO2 to CO with Noble Metal-Free Bis(terpyridine)iron(II) Complexes and an Organic Photosensitizer

Abstract

Summary

A photochemical reduction of CO₂ to CO was shown using the iron complexes xx, xx and xx as catalysts in combination with the organic photosensitizer 4CzIPN. Turnover numbers (TONs) of 6320 and a selectivity of 99.4% for CO were reached in DMF/H₂O with catalyst . The experiments were conducted under visible-light irradiation (λ = 440 nm) using TEA as sacrificial electron donor (see section SEDs below).
