Patent number: 8450236Abstract: A process for making a catalyst having precious metal nanoparticles deposited on a support includes first providing an aqueous dispersion of support particles. A pre-treatment slurry is prepared by mixing the aqueous dispersion of support particles with a water-soluble precious metal precursor and a reducing agent. The pre-treatment slurry is hydrothermally treated at a temperature in the range of from about 40° C. to about 220° C. for a time sufficient to deposit precious metal nanoparticles on the surface of the support particles, the precious metal nanoparticles having an average particle size less about 50 nm.Type: GrantFiled: April 13, 2010Date of Patent: May 28, 2013Assignee: Cristal USA Inc.Inventors: Guoyi Fu, Mark B.

Patent number: 8409518Abstract: A sulfur tolerant oxidation catalyst with appreciable NO and HC oxidation capabilities has been developed for use in any component of an exhaust aftertreatment system for a lean-burn engine where the oxidation of at least NO is desired. Several non-exclusive examples of such components where the oxidation catalyst may be employed include a DOC and a LNT. The oxidation catalyst may comprise perovskite oxide particles that support palladium particles. The ability of the palladium supported perovskite oxide particles to concurrently oxidize NO and HC's can significantly diminish or altogether eliminate the use of platinum in the exhaust aftertreatment system for at least NO oxidation. The oxidation catalyst, moreover, may exhibit superior thermal durability and better NO and HC oxidation activities than platinum in some instances.Type: GrantFiled: March 9, 2010Date of Patent: April 2, 2013Assignee: GM Global Technology Operations LLCInventors: Chang H Kim, Wei Li, Richard J.
