===Abstract=== | |||
====Summary==== | |||
A photochemical reduction of CO<sub>2</sub> was shown using the nickel catalyst {{#moleculelink:|link=IZFLGDSTXHVTSZ-UHFFFAOYSA-L|image=false|width=300|height=200}} and the copper-based photosensitizers {{#moleculelink:|link=OGUFRAGOGOMEFL-UHFFFAOYSA-P|image=false|width=300|height=200}}, {{#moleculelink:|link=XIYWTOURLVMHSU-UHFFFAOYSA-R|image=false|width=300|height=200}}, {{#moleculelink:|link=LMWHUTMATFLCSY-UHFFFAOYSA-R|image=false|width=300|height=200}} and{{#moleculelink:|link=WFPHYLSMKQIDJB-UHFFFAOYSA-R|image=false|width=300|height=200}}. Turnover numbers (TONs) of 8.1 for CO were reached in acetonitrile/TEOA for complex {{#moleculelink:|link=LMWHUTMATFLCSY-UHFFFAOYSA-R|image=false|width=300|height=200}} after 4 hours. Employing the other synthesized photosensitizers {{#moleculelink:|link=OGUFRAGOGOMEFL-UHFFFAOYSA-P|image=false|width=300|height=200}}, {{#moleculelink:|link=XIYWTOURLVMHSU-UHFFFAOYSA-R|image=false|width=300|height=200}} or {{#moleculelink:|link=WFPHYLSMKQIDJB-UHFFFAOYSA-R|image=false|width=300|height=200}}, TONs of 4.3 to 4.9 were obtained. The experiments were conducted under visible-light irradiation (λ = 420 nm) using BIH as sacrificial electron donor (see section SEDs below). | |||
====Advances and special progress==== | |||
The first example of Cu(I)-based photosensitizers used for photocatalytic CO<sub>2</sub> reduction in combination with {{#moleculelink:|link=IZFLGDSTXHVTSZ-UHFFFAOYSA-L|image=false|width=300|height=200}} was successfully reported, demonstrating the usability of a fully noble-metal free CO<sub>2</sub> reduction system. The TONs are consistent with previously reported results on noble-metal based photosensitizers. | |||
====Additional remarks==== | |||
The developed heteroleptic photosensitizer complexes showed a high stability in acetonitrile and no ligand release or formation of the homoleptic complexes was detected in UV/Vis stability studies. | |||
===Content of the published article in detail=== | |||
The article contains results for the reduction of CO<sub>2</sub> to CO under visible-light catalysis using a nickel complex as catalyst and copper-based photosensitizers. The catalytic system performs best (referring to the TON of CO production) in acetonitrile/TEOA with photosensitizer {{#moleculelink:|link=LMWHUTMATFLCSY-UHFFFAOYSA-R|image=false|width=300|height=200}}. | |||

Abstract[edit | edit source]
Summary[edit | edit source]
A photochemical reduction of CO2 was shown using the nickel catalyst Ni(cyclam)Cl2 and the copper-based photosensitizers 100906, 100907, 100908 and100909. Turnover numbers (TONs) of 8.1 for CO were reached in acetonitrile/TEOA for complex 100908 after 4 hours. Employing the other synthesized photosensitizers 100906, 100907 or 100909, TONs of 4.3 to 4.9 were obtained. The experiments were conducted under visible-light irradiation (λ = 420 nm) using BIH as sacrificial electron donor (see section SEDs below).
Advances and special progress[edit | edit source]
The first example of Cu(I)-based photosensitizers used for photocatalytic CO2 reduction in combination with Ni(cyclam)Cl2 was successfully reported, demonstrating the usability of a fully noble-metal free CO2 reduction system. The TONs are consistent with previously reported results on noble-metal based photosensitizers.
Additional remarks[edit | edit source]
The developed heteroleptic photosensitizer complexes showed a high stability in acetonitrile and no ligand release or formation of the homoleptic complexes was detected in UV/Vis stability studies.
Content of the published article in detail[edit | edit source]
The article contains results for the reduction of CO2 to CO under visible-light catalysis using a nickel complex as catalyst and copper-based photosensitizers. The catalytic system performs best (referring to the TON of CO production) in acetonitrile/TEOA with photosensitizer 100908.

Sacrificial Electron Donor[edit | edit source]
In this study, the experiments were done with the sacrificial electron donor BIH.
Additives[edit | edit source]
In this study, TEOA was used as a proton donor. For one experiment, N(Me)3 was employed instead. The catalyst [Cu(ACN)4][BF4] was used for a control experiment.
