====Summary====
A photochemical reduction of CO<sub>2</sub> to CO was shown using the nickel complex {{#moleculelink:|link=SOBXSEUOEROXNJ-UHFFFAOYSA-L|image=false|width=300|height=200}} as catalyst in combination with the ruthenium-based photosensitizer {{#moleculelink:|link=SJFYGUKHUNLZTK-UHFFFAOYSA-L|image=false|width=300|height=200}}. Turnover numbers (TONs) over 700 and a selectivity of >99% for CO were reached in dimethylacetamide/water. The experiments were conducted under visible-light irradiation (λ = 450 nm) using BIH as sacrificial reductants (see section SEDs below).
 
====Advances and special progress====
====Advances and special progress====
A nickel catalyst inspired by the CODH enzyme (carbon monoxide dehydrogenase) was employed for the photocatalytic reduction of CO<sub>2</sub> with the back then highest reported TON values among nickel complexes in systems with [Ru(bpy)<sub>3</sub>]<sup>2+</sup>.
 
====Additional remarks====
====Additional remarks====
The binding of CO<sub>2</sub> to the nickel(0) species was identified as the potential rate-determining step of the reduction.
 
=== Content of the published article in detail ===
=== Content of the published article in detail ===
The article contains results for the reduction of CO<sub>2</sub> to CO under visible-light catalysis using a nickel complex as a catalyst. The catalytic system performs best (referring to the TON of CO production) in dimethylacetamide/water.
