Cobalt porphyrins as homogeneous catalysts for water oxidation.

Takashi Nakazono¹, Alexander Rene Parent, Ken Sakai.

Abstract

Three water-soluble cobalt porphyrins have been investigated as water oxidation catalysts via photo-initiation using Ru(II)(bpy)3(2+)/Na2S2O8. The pH dependence of the turnover frequency revealed maximum activity at pH 11. Based on the second order dependence on catalyst concentration for the rate of water oxidation, we suggest a bimolecular radical coupling process as the rate determining step.
