  • Metal foil catalyst members by aqueous electrophoretic deposition
    Patent number: 5604174
    Abstract: Flexible metal foil catalyst members suitable for use in catalytic devices for combustion engine emission control are prepared by electrophoretic deposition using an aqueous slurry of catalyst support particles. The deposited support layer is of uniform thickness and stable surface area. The catalyst support may then be impregnated with catalytic species and assembled into a catalytic device. The catalyst members from the invention are especially suitable for use in automotive applications, and more especially in electrically heated catalytic devices.
    Type: Grant
    Filed: August 30, 1995
    Date of Patent: February 18, 1997
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: Semyon D. Friedman, Awdhoot V. Kerkar, Ernest W. Hughes, Rasto Brezny, John W. Lau, Jacob Block
