The Mo-based polyoxometalates containing mono- and dicobalt(iii) catalyst cores, [CoMo6O24H6]3−and [Co2Mo10O38H4]6−, were found to serve as O2-evolving catalysts in a system consisting of tris(2,2−-bipyridine)ruthenium(ii) (Ru(bpy)32+) and sodium persulfate (S2O 2− 8) in an aqueous borate buffer solution at pH 8.0. Kinetics of O2evolution reveals that the higher cobalt nuclearity is not necessary to attain the highly active nature of the catalyst.
