  • Nitrogen oxides storage catalysts containing cobalt
    Patent number: 7811536
    Abstract: Nitrogen oxides (NOx) storage catalysts comprising cobalt and barium with a lean NOx storage ratio of 1.3 or greater. The NOx storage catalysts can be used to reduce NOx emissions from diesel or gas combustion engines by contacting the catalysts with the exhaust gas from the engines. The NOx storage catalysts can be one of the active components of a catalytic converter, which is used to treat exhaust gas from such engines.
    Type: Grant
    Filed: July 21, 2006
    Date of Patent: October 12, 2010
    Assignee: University of Delaware
    Inventors: Jochen Lauterbach, Christopher M. Snively, Rohit Vijay, Reed Hendershot, Ben Feist
