Photocatalytic production of hydrogen peroxide from water and dioxygen using cyano-bridged polynuclear transition metal complexes as water oxidation catalysts

Abstract

Hydrogen peroxide was produced efficiently from water and dioxygen using [Ru-II(Me(2)phen)(3)](2+) (Me(2)phen = 4,7-dimethyl-1,10-phenanthroline) as a photocatalyst and cyano-bridged polynuclear transition metal complexes composed of Fe and Co as water oxidation catalysts in the presence of Sc3+ in water under visible light irradiation.
