Photochemical Reduction of Carbon Dioxide to Formic Acid using Ruthenium(II)-Based Catalysts and Visible Light: Difference between revisions

Latest revision as of 15:15, 5 July 2024

A photochemical reduction of CO₂ to formic acid was shown using a system containing an iridium-based photosensitizer, ruthenium photocatalyst and triethanolamine as the electron donor. Turnover numbers up to 526 and a selectivity of 80% towards formic acid were observed if the reaction was performed with [Ir(ppy)₂(bpy)]PF₆ ([Ir(ppy)2(bpy)][PF6]) as the photosensitizer and [Ru(bpy)₂(Cl)(CO)]PF₆ (100837) as the catalyst. The experiments were conducted under irradiation with Hg-lamp equipped with a λ=400–700 nm filter.

Advances and special progress[edit | edit source]

The employed photocatalytic system showed activity for the photoreduction of Na₂CO₃ to formic acid as well. A TON of 53 was observed after 5h reaction time.

Additional remarks[edit | edit source]

Experiments using different electron and proton donors such as triethylamine (TEA) and 1-benzyl-1,4-dihydronicotinamide (BNAH) were unsuccessful as the observed activities were lower than those obtained in the presence of TEOA.

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

The article contains results for the reduction of CO2 to formic under visible-light catalysis using ruthenium complexes as catalysts, the iridium complex [Ir(ppy)₂(bpy)]PF₆ ([Ir(ppy)2(bpy)][PF6]) as a photosensitizer and triethanolamine as the electron donor. The catalytic system performs best (referring to the TON of HCOOH production) with [Ru(bpy)₂(Cl)(CO)]PF₆ (100837) as photocatalyst.
