Ruthenium–cobalt dinuclear complexes as photocatalysts for CO2 reduction

Abstract

A series of Ru–Co dinuclear complexes have been synthesized and assayed as photocatalysts for the reduction of CO₂ to CO in organic solvents. The Ru–Co complexes, with tris-diimine coordination at the Co ion, are the best supramolecular photocatalysts for CO₂ reduction with a non-noble metal catalytic center reported so far.
