title: Low-overpotential water oxidation by a surface-bound ruthenium-chromophore-ruthenium-catalyst assembly.
abstract: When anchored to nanoITO (indium tin oxide), the ruthenium chromophore-catalyst assembly shown acts as an electrocatalyst for water oxidation, with O2 evolution occurring at an overpotential of 230 mV in 0.1 M HClO4 . The potential response of the electrode points to 3 e(-) /2 H(+) oxidized [Rua (III) Rub (IV) O](5+) as the active form of the assembly.
