ABSTRACT:
Disclosed is a catalyst, an emission control device, and a method for treating exhaust gas. In one embodiment, the catalyst comprises: a catalytic metal component and a macro-pore component. The macro-pore component comprises an oxygen storage component and an aluminum oxide component, wherein the oxygen storage component, the aluminum oxide component, or both comprise pores, and wherein greater than or equal to about 40% of a macro-pore component pore volume, based on a total macro-pore component pore volume, is associated with pores greater than 120 Åin diameter. In another embodiment, the method for treating an exhaust gas comprises: contacting the exhaust gas with the catalyst at a temperature and for a period of time sufficient to reduce the concentration of a material in the exhaust gas.
