Cp*iridium complexes（Cp*=C5Me5-）have recently been shown as effective precatalysts for the oxidation of water to molecular oxygen,which is recognized as the most challenging process in the realization of artificial photosynthesis aimed at producing solar *** nature of catalytic species,however,remains a matter of debate due to oxidative transformation of the *** our investigation of a Cp*-iridium carbene catalyst（Fig 1）in water oxidation using potassium peroxymonosulfate（Oxone）as primary oxidant,we found the precatalyst would evolve to a blue species when a small amount of Oxone was *** addition of Oxone would yield stable purple species,while previous studies on iridium-catalyzed water oxidation all pointed out the formation of blue solution as catalytic resting *** species have been proven to be homogeneous and they remain active in water *** intermediates during oxidative transformation were then analyzed.1H NMR profiles and MALDI-MS data suggested a rapid oxidation of the Cp*ligand to acetone,formic and acetic acid.1H NMR,TEM-EDX as well as MALDI-MS data indicated a continuous degradation of pyrimidyl,butyl and carbene ***-MS,XANES and 17O NMR spectroscopy data of the blue species are most consistent with an iridium（III）compound with two waters,one dioxygen and pm NHC *** purple catalytic resting species probably consists of an iridium（III）complex with three waters,one chloride and one bicarbonate ***,the presence of a small amount of iridium aqua ion oligomers was observed in the purple *** formation of more polymers and nanoparticles is likely to be inhibited by the acid environment.
