Abstract
Summary
A photochemical reduction of CO2 to CO was shown using the iron complex 100941 as catalyst in combination with the copper photosensitizer 100940. Turnover numbers (TONs) of 576 and a selectivity of 67% for CO were reached in MeCN/TEOA. The experiments were conducted under visible-light irradiation (λ = 420 nm) using BIH as sacrificial electron donor (see section SEDs below).
Advances and special progress
The authors reported a iron complex with one of the highest activities for CO2 reduction among earth-abundant systems with monometallic iron catalysts.
Additional remarks
In addition to the production of CO, a substantial amount of H2 was formed in the reduction process with a TON of 287.
Content of the published article in detail
The article contains results for the reduction of CO2 to CO under visible-light catalysis using an iron complex as a catalyst. The catalytic system performs best (referring to the TON of CO production) in MeCN/TEOA.
