High quantum yield photochemical water oxidation using a water-soluble cobalt phthalocyanine as a homogenous catalyst

摘要

We demonstrated high catalytic activity (TON = 670, TOFmax = 2.7 s−1) of a water-soluble cobalt phthalocyanine complex (CoPcTS, PcTS = phthalocyaninetetrasulfonate) for visible light-driven photochemical water oxidation and investigated its reaction mechanism by electrochemical and spectroscopic measurements.
