===Abstract===
====Summary====
A photochemical reduction of CO<sub>2</sub> to CO was shown using the iron complex  as catalyst in combination with the organic photosensitizer {{#moleculelink:|link=PRWATGACIORDEL-UHFFFAOYSA-N|image=false|width=300|height=200}}. Turnover numbers (TONs) of 6320 and a selectivity of 99.4% for CO were reached in DMF/H<sub>2</sub>O. The experiments were conducted under visible-light irradiation (λ = 440 nm) using TEA as sacrificial electron donor (see section SEDs below).
====Advances and special progress====
====Additional remarks====
===Content of the published article in detail===
The article contains results for the reduction of CO<sub>2</sub> to CO under visible-light catalysis using the iron complex  as a catalyst. The catalytic system performs best (referring to the TON of CO production) in DMF/H<sub>2</sub>O.

Abstract

Summary

A photochemical reduction of CO2 to CO was shown using the iron complex as catalyst 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. The experiments were conducted under visible-light irradiation (λ = 440 nm) using TEA as sacrificial electron donor (see section SEDs below).
