Visible-Light Photocatalytic Conversion of Carbon Dioxide by Ni(II) Complexes with N4S2 Coordination: Highly Efficient and Selective Production of Formate: Difference between revisions

Latest revision as of 10:37, 11 April 2024

A photochemical reduction of CO₂ to formate was shown using the nickel complexes Ni(pbi)(pyS)2 or Ni(pbt)(pyS)2 as catalysts in combination with the organic photosensitizer Eosin Y. Turnover numbers (TONs) of up to 14000 and a selectivity of >99% for formate were reached in ethanol/water. The experiments were conducted under visible-light irradiation (λ > 400 nm) using TEOA as sacrificial electron donor (see section SEDs below).

Advances and special progress[edit | edit source]

A set of bioinspired nickel complexes have been developed and shown to possess remarkably high efficiencies and selectivities as catalysts in CO₂ reduction, being the (at that time) best early transition metal complexes for photocatalytic CO₂ conversion.

Additional remarks[edit | edit source]

The nickel complexes were also active catalysts for hydrogen photoreduction under argon atmosphere.

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

The article contains results for the reduction of CO₂ to formate under visible-light catalysis using nickel complexes and an organic photosensitizer. The catalytic system performs best (referring to the TON of formate production) in ethanol/water with complex Ni(pbi)(pyS)2 as a catalyst.
