===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. In addition, they reported the use of a cheap organic photosensitizer for CO2 conversion with a slightly lower TON (60), but higher selectivity (100%).

====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}}.
