  • Platinum group metal (PGM) catalysts for automotive emissions treatment
    Patent number: 10201804
    Abstract: Catalytic materials for exhaust gas purifying catalyst composites comprise platinum group metal (PGM)-containing catalysts whose PGM component(s) are provided as nanoparticles and are affixed to a refractory metal oxide, which may be provided as a precursor. Upon calcination of the catalysts, the PGM is thermally affixed to and well-dispersed throughout the support. Excellent conversion of hydrocarbons and nitrogen oxides can advantageously be achieved using such catalysts.
    Type: Grant
    Filed: January 29, 2016
    Date of Patent: February 12, 2019
    Assignees: BASF Corporation, Georgia Tech Research Corporation
    Inventors: Andrey Karpov, David Preli, Knut Wassermann, Andreas Sundermann, Sang-IL Choi, Ping Lu, Younan Xia
  • Rhodium-containing catalysts for automotive emissions treatment
    Patent number: 10183276
    Abstract: Catalytic materials, and in particular, rhodium-containing catalytic materials for exhaust gas purifying catalyst composites are provided herein. Such materials comprise multimetallic Rh-containing nanoparticles, which are present primarily inside aggregated particles of a support (such as alumina). Such catalytic materials can exhibit excellent conversion of hydrocarbons and nitrogen oxides.
