文摘

Synergistic catalytic effects aid the photocatalytic reduction of CO₂ to CO by a dinuclear cobalt cryptate complex in CH₃CN/H₂O solution. In their Communication on page 738 ff., D. C. Zhong, T. B. Lu, and co-workers demonstrate that one Co^II unit serves as a catalytic center and the other Co^II unit acts as an assistant catalytic site to facilitate the cleavage of the C−O bond of the O=C−OH intermediate, thus leading to a higher catalytic activity than for the corresponding mononuclear Co^II complex.
