Efficient light-driven water oxidation catalyzed by a mononuclear cobalt(iii) complex†
Abstract
A mononuclear Co complex, [CoIII(DPK·OH)2]Cl (DPK = di(2-pyridyl)ketone), was synthesized and reported as a stable catalyst in visible light-driven water oxidation. The optimum turnover number (TON) of complex 1 is 1610, which, to the best of our knowledge, is the largest TON among metal–organic complexes for photocatalytic water oxidation.
