When anchored to nanoITO (indium tin oxide), the ruthenium chromophore–catalyst assembly shown acts as an electrocatalyst for water oxidation, with O 2 evolution occurring at an overpotential of 230 mV in 0.1 M HClO 4 . The potential response of the electrode points to 3 e − /2 H + oxidized [Ru a III Ru b IV O] 5+ as the active form of the assembly.
