  • Hydrothermally and thermally stable catalytic materials based on theta-alumina
    Patent number: 11857950
    Abstract: A material and a method of making hydrothermally stable (catalytic) materials on the basis of theta-alumina support that is thermally and hydrothermally stable up to 1,150 C with metal, mixed metal-, metal-oxide nanoparticles dispersed upon it. Such materials did not lose significant amounts of their catalytic activity at temperature ranges for industrially relevant applications (including hydrocarbon oxidation, nitric oxide reduction, carbon monoxide oxidation) even after hydrothermal aging up to 1,150° C.
    Type: Grant
    Filed: November 17, 2021
    Date of Patent: January 2, 2024
    Assignee: BATTELLE MEMORIAL INSTITUTE
    Inventors: Konstantin Khivantsev, Libor Kovarik, Janos Szanyi, Yong Wang, Ja-Hun Kwak, Nicholas R. Jaegers

  • High-capacity, low-temperature, passive NOx and cd adsorbers and methods for making same
    Patent number: 11071966
    Abstract: Disclosed are passive NOx adsorbers and methods for synthesizing the same. Small-pore zeolitic materials with practical loadings of transition metals atomically dispersed in the micropores are described herein. Also demonstrated are simple and scalable synthesis routes to high loadings of atomically dispersed transition metals in the micropores of a small-pore zeolite.
