==== Summary====
[[Category:Photocatalytic CO2 conversion to HCOOH]]
A photochemical reduction of CO<sub>2</sub> to CO or formic acid was shown using the bipyridine-based rhenium, ruthenium and manganese catalysts {{#moleculelink:|link=NZCMNMSVXYOMGS-UHFFFAOYSA-N|image=false|width=300|height=200}}, {{#moleculelink: |link=XUQJAKJUMNDNTK-UHFFFAOYSA-L|image=false|width=300|height=200}} or {{#moleculelink: |link=OMERWMHUIAGAOR-UHFFFAOYSA-N|image=false|width=300|height=200}} in combination with cyclic rhenium-based trinuclear redox photosensitizers. Turnover numbers (TONs) of  up to 290 for formic acid were reached in DMA with the ruthenium complex {{#moleculelink: |link=XUQJAKJUMNDNTK-UHFFFAOYSA-L|image=false|width=300|height=200}} and photosensitizer {{#moleculelink: |link=JLRZSCLFGATQEH-UHFFFAOYSA-T|image=false|width=300|height=200}}. For CO production, TONs of up to 98 were obtained in DMF with the rhenium complex {{#moleculelink:|link=NZCMNMSVXYOMGS-UHFFFAOYSA-N|image=false|width=300|height=200}} and photosensitizer {{#moleculelink: |link=LKSLWZSWOWNWCR-UHFFFAOYSA-T|image=false|width=300|height=200}}. The experiments were conducted under visible-light irradiation (λ = 436 nm) using TEOA as sacrificial electron donor (see section SEDs below).
====Advances and special progress====
Re(I)-based trinuclear photosensitizers were developed and allowed for high product selectivities for CO or formic acid in CO<sub>2</sub> reduction attempts with different bipyridine-based catalysts.
 
====Additional remarks====
===Content of the published article in detail===
The article contains results for the reduction of CO<sub>2</sub> to CO or formic acid under visible-light catalysis using bipyridine-based complexes and rhenium-based trinuclear rings as photosensitizers. The catalytic system performs best in DMA for formic acid production (referring to the TON of formic acid production) and in DMF for CO production.

Abstract[edit | edit source]

Summary[edit | edit source]

A photochemical reduction of CO2 to CO or formic acid was shown using the bipyridine-based rhenium, ruthenium and manganese catalysts [Re(bpy)(CO)3(MeCN)][PF6], Ru(dtBubpy)(CO)2Cl2 or [Mn(dtBubpy)(CO)3(MeCN)][PF6] in combination with cyclic rhenium-based trinuclear redox photosensitizers. Turnover numbers (TONs) of up to 290 for formic acid were reached in DMA with the ruthenium complex Ru(dtBubpy)(CO)2Cl2 and photosensitizer 100877. For CO production, TONs of up to 98 were obtained in DMF with the rhenium complex [Re(bpy)(CO)3(MeCN)][PF6] and photosensitizer 100878. The experiments were conducted under visible-light irradiation (λ = 436 nm) using TEOA as sacrificial electron donor (see section SEDs below).

Advances and special progress[edit | edit source]

Re(I)-based trinuclear photosensitizers were developed and allowed for high product selectivities for CO or formic acid in CO2 reduction attempts with different bipyridine-based catalysts.

Additional remarks[edit | edit source]

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

The article contains results for the reduction of CO2 to CO or formic acid under visible-light catalysis using bipyridine-based complexes and rhenium-based trinuclear rings as photosensitizers. The catalytic system performs best in DMA for formic acid production (referring to the TON of formic acid production) and in DMF for CO production.
