Exploring the Full Potential of Photocatalytic Carbon Dioxide Reduction Using a Dinuclear Re2Cl2 Complex Assisted by Various Photosensitizers: Difference between revisions

Latest revision as of 09:33, 10 May 2024

A photochemical reduction of CO₂ to CO was shown using the dirhenium complex (tBuxant)-(Re(bpy)(CO)3Cl)2 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[edit | edit source]

One of very few studies where a dinuclear catalytic system able to activate CO₂ is used in combination with photosensitizers.

Additional remarks[edit | edit source]

The experiments were performed 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[edit | edit source]

The article contains results of a detailed study on the influence of additional photosensitizers on the catalytic performance of the dinuclear rhenium catalyst (tBuxant)-(Re(bpy)(CO)3Cl)2 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.
