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, TiOformed by Atomic Layer Deposition (ALD). A 'chromophore-catalyst assembly' 1, [(POH)bpy)Ru(4-Mebpy-4-bimpy)Ru(tpy)(OH)], which combines both light absorber and water oxidation catalyst in a single molecule, is attached to the TiOshell. Visible photolysis of the resulting core/shell/assembly structure with a Pt cathode results in water splitting into hydrogen and oxygen.
