Abstract
Summary
The photochemical reduction of CO2 to CO was shown using the iron complex Fe(DHPP)Cl in combination with the photosensitizers xx or xx. Turnover numbers (TONs) of up to 140 and a selectivity of xx for CO were reached in acetonitrile after xx h of irradiation. The experiments were conducted under visible-light irradiation (λ > 400 nm) with TEA (see section SEDs below) as sacrificial electron donor.
Advances and special progress
Additional remarks
Content of the published article in detail
The article contains results of a study for the reduction of CO2 to CO using an iron complex and an iridium-based photosensitizer. The catalytic system performs best (referring to the TON of CO production) in acetonitrile with photosensitizer xx.
