Abstract
Summary
A photochemical reduction of CO2 to CO was shown using the dirhenium complex Molecule with key SPPICNUXBVPFDY-UHFFFAOYSA-N does not exist. in combination with the ruthenium and copper photosensitizers Ir(fppy)3 and [Cu(bcp)(xant)][PF6]. Turnover numbers (TONs) of up to 270 were reached after 4 h of irradiation (λ > 400 nm) in DMF.
Advances and special progress
One of very few studies where a dinuclear catalytic system able to activate CO2 is used in combination with photosensitizers.
Additional remarks
The experiments were preformed using the rhenium complex (50 μM in DMF) as the catalyst in combination with different loadings of the sensitizers and sacrificial electron donors under 4 h of irradiation with λ > 400 nm.
Content of the published article in detail
The article contains results of a detailed study on the influence of additional photosensitizers on the catalytic performance of the dinuclear rhenium catalyst Molecule with key SPPICNUXBVPFDY-UHFFFAOYSA-N does not exist. for the reduction of CO2 to CO. The catalytic system performs best (referring to the TON of CO production) for the combination of the above mentioned catalyst with the iridium complex Ir(fppy)3 as the photosensitizer in the presence of BIH/TEA as sacrificial electron donors.
