Abstract

Summary

In this article CO2 was reduced to CO by using the dinuclear cobalt catalyst 100776 along with the photosensitizer [Ru(phen)3][PF6]2. The photoreaction displayed a high TON of 16896 under 450 nm LED irradiation in 10 h. These good results are attributed to the synergetic effect of the two close cobalt atoms.

Advances and Special progress

This new catalyst displays high efficiency and a very good selectivity of 98% towards CO.

Additional remarks

Content of the published article in detail

This article emphasizes on the efficiency and selectivity of this new dinuclear complex as it is the first one with such good properties in photocatalysis, especially as it works in water containing conditions and shows good results also with only 10% CO2 in atmosphere.
