====Summary====
A photochemical reduction of CO<sub>2</sub> to CO was shown using the copper cryptate  as catalyst in combination with the ruthenium photosensitizer . Turnover numbers (TONs) up to 51392 and a selectivity of 98% for CO were reached in MeCN/H<sub>2</sub>O. The experiments were conducted under visible-light irradiation (λ = 450 nm) using TEOA as sacrificial electron donor (see section SEDs below).

Abstract[edit | edit source]

Summary[edit | edit source]

A photochemical reduction of CO2 to CO was shown using the copper cryptates 100956 or 100957 as catalyst in combination with the ruthenium photosensitizer [Ru(phen)3][PF6]2. Turnover numbers (TONs) up to 51392 and a selectivity of 98% for CO were reached in MeCN/H2O. The experiments were conducted under visible-light irradiation (λ = 450 nm) using TEOA as sacrificial electron donor (see section SEDs below).

Advances and special progress[edit | edit source]

The authors presented a highly active copper-based catalyst for the visible-light catalyzed reduction of CO2 to CO with high TON and TOF values.

Additional remarks[edit | edit source]

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

The article contains results for the reduction of CO2 to CO under visible-light catalysis using a copper complex as a catalyst. The catalytic system performs best (referring to the TON of CO production) in MeCN/H2O with complex 100956.
