Enhanced oxygen evolution through electrochemical water oxidation mediated by polynuclear complexes embedded in a polymer film

Abstract
Oxygen evolution by electrochemical water oxidation has been studied. The reaction was carried out through electrochemical water oxidation mediated by polynuclear complexes embedded in a Nafion film. The polynuclear complexes used were the µ-oxo-trinuclear ruthenium complex, [(NH3)5 RuORu(NH3)4ORu(NH3)5]Cl6 and [graphic omitted]. These complexes are effective as mediators for enhanced oxygen evolution. The mediated water oxidation has been demonstrated by potential vs. current characteristics and by oxygen analysis by gas chromatography.
