Abstract
The monomeric ruthenium complex cis-[Ru(bpy)2(H2O)2]2+ was adsorbed into a Nafion® film coated onto an indium tin oxide (ITO) electrode. In-situ spectrocyclic voltammetric investigations under different pH conditions showed that the monomeric complex in the Nafion film dimerizes upon oxidation, with obvious spectral changes, to yield the corresponding oxo-bridged complex [(bpy)2(H2O)Ru---O---Ru(H2O)(bpy)2]4+ which is a water oxidation catalyst. The reversible formation of the dimer and monomer during oxidation and reduction of the corresponding complexes at appropriate potentials was established by in-situ spectrocyclic voltammetry at a Nafion-film-coated ITO electrode.
