Abstract
Summary
A photochemical reduction of CO2 to CO was shown using the ruthenium catalyst and sensitizer Ru(dppq)(tpy)(MeCN). Turnover numbers (TONs) up to 353 and a selectivity of 97% for CO were reached in dimethylacetamide/water. The experiments were conducted under visible-light irradiation (λ = 420-750 nm) with BIH or TEOA (see section SEDs below) as sacrificial electron donors.
