Abstract
Summary
A photochemical reduction of CO2 to CO was shown using xx as catalyst in combination with the organic carbazole-based photosensitizer . Turnover numbers (TONs) of xx and a selectivity of xx% for CO were reached in MeCN/H2O with catalyst xx. The experiments were conducted under visible-light irradiation (λ = 400 nm) using ascorbic acid as sacrificial electron donor (see section SEDs below).
Advances and special progress
Additional remarks
Content of the published article in detail
The article contains results for the reduction of CO2 to CO under visible-light catalysis using xx as a catalyst. The catalytic system performs best (referring to the TON of CO production) in MeCN/H2O.
Catalyst
Photosensitizer
3,6-bis(dimethylamino)-9-phenyl-9H-carbazole
Investigation
Sacrificial electron donor
In this study, the experiments were done with the sacrificial electron donor ascorbic acid L-ascorbate, sodium. The use of BIH was tested, but found to yield worse results.
Additives
In this study, potassium carbonate was added as a base.
Investigations
- photocatalytic CO2 conversion under different conditions (Molecular process, Photocatalytic CO2 conversion experiments)
