==== Investigation ====
=== Abstract ===


==== Catalyst ====
==== Summary ====
A photochemical reduction of CO<sub>2</sub> was shown using the manganese catalyst {{#moleculelink:|link=ZUZWBGQHMPVNDY-UHFFFAOYSA-M|image=false|width=300|height=200}} and the zinc photosensitizer {{#moleculelink:|link=XPVVGUHKLPZAEN-DAJBKUBHSA-N|image=false|width=300|height=200}}. Turnover numbers (TONs) of 64 and 16 were reached after 180 min of irradiation for CO and formic acid, respectively. The experiments were performed using a Xenon lamp as the light source.
 
==== Advances and special progress ====
Photochemical CO<sub>2</sub> conversion in an environmentally friendly and sustainable photocatalytic system using earth abundant metal complexes efficiently yielded CO and HCOOH in aqueous acetonitrile solution.
 
==== Additional remarks ====
The manganese catalyst and the zinc photosensitizer were used in different ratios, resulting in different TONs for CO and HCOOH production.
 
=== Content of the published article in detail ===
The article contains results for the reduction of CO<sub>2</sub> to CO and HCOOH using different ratios of the catalyst and photosensitizer. The catalytic system performed best (referring to the TONs of CO and HCOOH production) for the catalyst:photosensitizer ratio of 4:1.

Abstract[edit | edit source]

Summary[edit | edit source]

A photochemical reduction of CO2 was shown using the manganese catalyst Mn(bpy)(CO)3Br and the zinc photosensitizer ZnTPP. Turnover numbers (TONs) of 64 and 16 were reached after 180 min of irradiation for CO and formic acid, respectively. The experiments were performed using a Xenon lamp as the light source.

Advances and special progress[edit | edit source]

Photochemical CO2 conversion in an environmentally friendly and sustainable photocatalytic system using earth abundant metal complexes efficiently yielded CO and HCOOH in aqueous acetonitrile solution.

Additional remarks[edit | edit source]

The manganese catalyst and the zinc photosensitizer were used in different ratios, resulting in different TONs for CO and HCOOH production.

Content of the published article in detail[edit | edit source]

The article contains results for the reduction of CO2 to CO and HCOOH using different ratios of the catalyst and photosensitizer. The catalytic system performed best (referring to the TONs of CO and HCOOH production) for the catalyst:photosensitizer ratio of 4:1.
