Abstract

A supported oxidation catalyst includes a support having a metal oxide or metal salt, and mixed metal particles thereon. The mixed metal particles include first particles including a palladium compound, and second particles including a precious metal group (PMG) metal or PMG metal compound, wherein the PMG metal is not palladium. The oxidation catalyst may also be used as a gas sensor.

Method of forming supported doped palladium containing oxidation catalysts

Patent Mohajeri, Nahid

A method of forming a supported oxidation catalyst includes providing a support comprising a metal oxide or a metal salt, and depositing first palladium compound particles and second precious metal group (PMG) metal particles on the support while in a liquid phase including at least one solvent to form mixed metal comprising particles on the support. The PMG metal is not palladium. The mixed metal particles on the support are separated from the liquid phase to provide the supported oxidation catalyst.

Mesoporous metal doped cerium oxide catalyst

Patent Suib, Steven L.; Guild, Curtis; Kriz, David

A mesoporous metal doped cerium oxide catalyst is provided. The catalyst can contain nanotextured cerium oxide (CeO2) which can be utilized for hydrogen production or reformate gas purification in a water gas shift reaction. The catalyst may be advantageously used to remove CO from a gas containing CO. The catalyst may also be incorporated into a fuel processor.

Method and system for the combination of non-thermal plasma and metal/metal oxide doped .gamma.-alumina catalysts for diesel engine exhaust aftertreatment system

Patent Aardahl, Christopher L [Richland, WA]; Balmer-Miller, Mari Lou [West Richland, WA]; Chanda, Ashok [Peoria, IL]; ...

The present disclosure pertains to a system and method for treatment of oxygen rich exhaust and more specifically to a method and system that combines non-thermal plasma with a metal doped .gamma.-alumina catalyst. Current catalyst systems for the treatment of oxygen rich exhaust are capable of achieving only approximately 7 to 12% NO.sub.x reduction as a passive system and only 25 40% reduction when a supplemental hydrocarbon reductant is injected into the exhaust stream. It has been found that treatment of an oxygen rich exhaust initially with a non-thermal plasma and followed by subsequent treatment with a metal doped .gamma.-aluminamore » « less

Nitrogen oxides storage catalysts containing cobalt

Patent Lauterbach, Jochen [Newark, DE]; Snively, Christopher M [Clarks Summit, PA]; Vijay, Rohit [Annandale, NJ]; ...

Nitrogen oxides (NO.sub.x) storage catalysts comprising cobalt and barium with a lean NO.sub.x storage ratio of 1.3 or greater. The NO.sub.x storage catalysts can be used to reduce NO.sub.x emissions from diesel or gas combustion engines by contacting the catalysts with the exhaust gas from the engines. The NO.sub.x storage catalysts can be one of the active components of a catalytic converter, which is used to treat exhaust gas from such engines.
