  • Exhaust gas purifying catalyst and method for producing the same
    Patent number: 10189011
    Abstract: An exhaust gas purifying catalyst with an excellent effect of suppressing deterioration due to aggregation of a noble metal catalyst during endurance at high temperature, and a production method therefor. The method for producing the exhaust gas purifying catalyst that has a porous carrier and a noble metal catalyst supported thereon includes: preparing the porous carrier that contains alumina-ceria-zirconia composite oxide particles and has physical property values, after subjected to baking at 900° C. for 5 hours, of a pore diameter of the particles in the range of 2 to 20 nm, a specific surface area of the particles in the range of 75 to 115 m2/g, a crystallite size of a ceria-zirconia composite oxide contained in the particles in the range of 4 to 6 nm, and a bulk density of the particles in the range of 0.5 to 0.
    Type: Grant
    Filed: September 12, 2017
    Date of Patent: January 29, 2019
    Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHA
    Inventors: Takaaki Kanazawa, Shunsuke Haga, Isao Naito, Akiya Chiba, Motoya Abe
