Abstract

New multi-cobalt-containing polyoxometalates (POMs) are soluble, fast and tunable water oxidation catalysts (WOCs). We report additional studies of [Co₄(H₂O)₂(PW₉O₃₄) ₂]^10- (1), a very fast, soluble and oxidative stable WOC: new kinetics data further indicate that Co²⁺ is not kinetically important in water oxidations catalyzed by 1. Second, we report a new WOC, [{Co₄(μ-OH)(H₂O)₃}(Si₂W ₁₉O₇₀)]^11- that coexists in a 1:1 ratio in the solid state (2a and 2b), and while it is oxidatively stable, it is not hydrolytically stable, rearranging to [Co(H₂O)SiW₁₁O ₃₉]^6- in aqueous solution. All these studies provide insights relating structural, electronic and other features of these WOCs to their reactivity and stability.
