  • Catalyst support material having high oxygen storage capacity and method of preparation thereof
    Patent number: 6528451
    Abstract: Mixed oxides of cerium oxide and zirconium oxides having a high oxygen storage and high oxygen release rate are disclosed. The mixed oxides are made of polycrystalline particles of cerium oxide and zirconium oxide having a controlled domain structure on the subcrystalline level wherein adjacent domains within a single crystallite have a different ratio of zirconium and cerium. The mixed oxides are prepared by a co-precipitation technique using mixed salt solutions of cerium and zirconium having a solid content of at least 23%, based on an oxide basis.
    Type: Grant
    Filed: March 13, 2001
    Date of Patent: March 4, 2003
    Assignee: W.R. Grace & Co.-Conn.
    Inventors: Rasto Brezny, Manoj M Koranne, Takeshi Egami, Eugene Mamontov
