====Summary====
The photochemical reduction of CO<sub>2</sub> to CO was shown using the iron complex {{#moleculelink:|link=JQYRTQVHCKLBTL-YQGGSDPOSA-M|image=false|width=300|height=200}} in combination with the photosensitizers xx or xx. Turnover numbers (TONs) of up to 140 and a selectivity of xx for CO were reached in acetonitrile after xx h of irradiation. The experiments were conducted under visible-light irradiation (λ > 400 nm) with TEA (see section SEDs below) as sacrificial electron donor.

====Additional remarks====
===Content of the published article in detail===
The article contains results of a study for the reduction of CO<sub>2</sub> to CO using an iron complex and an iridium-based photosensitizer. The catalytic system performs best (referring to the TON of CO production) in acetonitrile with photosensitizer xx.

Abstract

Summary

The photochemical reduction of CO2 to CO was shown using the iron complex Fe(DHPP)Cl in combination with the photosensitizers xx or xx. Turnover numbers (TONs) of up to 140 and a selectivity of xx for CO were reached in acetonitrile after xx h of irradiation. The experiments were conducted under visible-light irradiation (λ > 400 nm) with TEA (see section SEDs below) as sacrificial electron donor.
