Abstract
Summary
A photochemical reduction of CO2 to formic acid was shown using the rhenium catalyst and sensitizer [Re(bpy)2(CO)2][OTf] in combination with the supplemental photosensitizer [Ru(bpy)3][PF6]. Turnover numbers (TONs) up to 428 for formic acid were reached in dimethylacetamide. The experiments were conducted under visible-light irradiation (λ = 405 nm) with TEOA (see section SEDs below) as sacrificial electron donor.
