Abstract
Provided are catalyst composites that can be used in methods for treating exhaust gas from internal combustion engines, including diesel and gasoline engines, systems including such catalyst composites and methods of using the catalyst composites to treat internal combustion engine exhaust. The catalyst composites may provide diesel oxidation catalysts and three-way catalysts. A catalyst composite is provided which a catalytic material on a carrier, the catalytic material including a palladium component dispersed on a first support comprising at least 60% by weight of a zirconia component, and one or more rare earth oxides selected from the group consisting of lanthana, neodymia, praseodymia, yttria, the first support optionally containing no more than 15% by weight ceria, and being free of alumina. Layered catalyst composites having one or more washcoats on the carrier are also provided.
