  • Platinum nanoparticle deposition on a series of UiO metal-organic frameworks
    Patent number: 12247295
    Abstract: Deposition of Pt nanoparticles on UiO metal organic frameworks via solvothermal reduction is achieved by reducing Pt acetylacetonate (Pt(acac)2) in a UiO-66 and N,N-dimethylformamide (DMF) mixture at, for example, 130° C. for 18 hrs. Modification of reaction temperature and time can control the size of the Pt nanoparticles.
    Type: Grant
    Filed: August 28, 2023
    Date of Patent: March 11, 2025
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Hannah Marie Ashberry, Albert Epshteyn, James A. Ridenour, William A. Maza, Olga Baturina
  • Pyrolysis of 2D Coordination Polymer Precursors for the Formation of ORR Active Solid Acid Fuel Cell Electrode Catalysts
    Publication number: 20240067780
    Abstract: Described herein is the preparation of solid acid fuel cell (SAFC) electrode materials suitable for intermediate temperature (200° C.-300° C.) oxygen reduction reaction (ORR) catalysis via anaerobic, in vacuo pyrolysis of metal-organic coordination polymer precursor materials with divalent metals (e.g. Pt or Pd) as nodes to form small, catalytically active nanoparticles inside a porous, electrically conductive carbonized framework.
