Abstract[edit | edit source]

Summary[edit | edit source]

A photochemical reduction of CO2 to formic acid was shown using the ruthenium pincer complexes Ru(py)-(HNdpp)2(CO)2Cl and Ru(py)-(MeNdpp)2(CO)2Cl as catalyst in combination with the ruthenium-based photosensitizer [Ru(bpy)3][PF6]. Turnover numbers (TONs) of 380 for formic acid were reached in dimethylformamide with complex Ru(py)-(MeNdpp)2(CO)2Cl. The experiments were conducted under visible-light irradiation (λ = 405 nm) using TEOA as sacrificial electron donor (see section SEDs below).

Advances and special progress[edit | edit source]

The authors report a novel molecular architecture for a ruthenium photocatalyst active in the reduction of CO2 to formic acid, displaying competitive TONs and quantum yields up to 14%.

Additional remarks[edit | edit source]

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