===Abstract===
====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 {{#moleculelink:|link=NSABRUJKERBGOU-UHFFFAOYSA-N|image=false|width=300|height=200}} or {{#moleculelink:|link=KEQZHLAEKAVZLY-UHFFFAOYSA-N|image=false|width=300|height=200}}. Turnover numbers (TONs) of up to 140 and a selectivity of 93% for CO were reached in acetonitrile after 55 h of irradiation. The experiments were conducted under visible-light irradiation (λ > 400 nm) with TEA (see section SEDs below) as sacrificial electron donor.
====Advances and special progress====
The authors reported one of the highest TONs in homogeneous photocatalysis at that time in this study without detecting significant degradation of the catalyst or sensitizer.

====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 or organic photosensitizer. The catalytic system performs best (referring to the TON of CO production) in acetonitrile with photosensitizer {{#moleculelink:|link=NSABRUJKERBGOU-UHFFFAOYSA-N|image=false|width=300|height=200}}.
