Abstract

Incorporation of a small amount of Ca²⁺ ions into a polymeric cobalt cyanide complex to form Ca_x[Co^II(H₂O)₂]_1.5-x[Co^III(CN)₆] resulted in a significant enhancement of activity for photocatalytic water oxidation in a buffer solution (pH 7.0) containing [Ru(bpy)₃]²⁺ (bpy = 2,2′-bipyridine) as a photocatalyst and Na₂S₂O₈ as an electron acceptor to achieve a quantum efficiency of 200%.
