A photoelectrochemical device for visible light driven water splitting by a molecular ruthenium catalyst assembled on dye-sensitized nanostructured TiO2

A photoelectrochemical device with a molecular Ru catalyst assembled via pH-modified Nafion on a dye-sensitized nanostructured TiO(2) film as anode and a Pt foil as cathode has been successfully demonstrated to split water into O(2) and H(2) driven by visible light.
