  • Solar water splitting in a molecular photoelectrochemical cell
    Patent number: 10119197
    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, TiO2 formed by Atomic Layer Deposition (ALD). A “chromophore-catalyst assembly” 1, [(PO3H2)2bpy)2Ru(4-Mebpy-4-bimpy)Ru(tpy)(OH2)]4+, which combines both light absorber and water oxidation catalyst in a single molecule, is attached to the TiO2 shell. Visible photolysis of the resulting core/shell/assembly structure with a Pt cathode results in water splitting into hydrogen and oxygen.
    Type: Grant
    Filed: September 8, 2014
    Date of Patent: November 6, 2018
    Assignees: The University of North Carolina at Chapel Hill, North Carolina State University
    Inventors: Leila Alibabaei, Matthew Kyle Brennaman, Michael Norris, Gregory N. Parsons, Thomas J. Meyer
