Title: Solar water splitting in a molecular photoelectrochemical cell

Abstract

A Dye Sensitized Photoelectrosynthesis Cell (DSPEC) splits water with visible light using a derivatized, core/shell nanostructured photoanode with the core having a high surface area conductive metal oxide film--such as nanoITO (indium tin oxide) or nanoATO (antimony tin oxide)--coated with a thin outer shell of, for example, TiO 2 formed by Atomic Layer Deposition (ALD). A "chromophore-catalyst assembly" 1, [(PO 3H 2) 2bpy) 2Ru(4-Mebpy-4-bimpy)Ru(tpy)(OH 2)].s- up.4+, which combines both light absorber and water oxidation catalyst in a single molecule, is attached to the TiO 2 shell. Visible photolysis of the resulting core/shell/assembly structure with a Pt cathode results in water splitting into hydrogen and oxygen.
