Solar fuels generated in conjunction with the oxidation of water are a promising means of alleviating the world’s energy crisis. Robust water oxidation catalysts produced using earth abundant materials are key to implementation of this emerging technology on the scale necessary. To this end our lab has recently studied and reported a water oxidation catalyst, {[(L)Cu(II)]2}(μ-OH)2}(OTf)2 (L=Me2TMPA bis((6-methyl-2-pyridyl)methyl)(2-pyridylmethyl)-amine), under electrochemical conditions. We have recently discovered that this catalyst can also function under photocatalytic conditions. Specifically, addition of a Ru photosensitizer, sacrificial oxidant, and visible light results in evolution of dioxygen. Recent results and mechanistic insight will be presented.
