Abstract
A diesel oxidation catalyst composition is provided, the composition including at least one platinum group metal impregnated onto a porous refractory oxide material in particulate form and at least one base metal oxide impregnated onto a porous refractory oxide material in particulate form, wherein the porous refractory oxide material impregnated with at least one platinum group metal and the porous refractory oxide material impregnated with at least one base metal oxide are in the form of a mixture or wherein the at least one platinum group metal and the at least one base metal oxide are impregnated on the same porous refractory oxide material. The diesel oxidation catalyst provides synergistic enhancement of carbon monoxide oxidation as well as relatively unimpaired hydrocarbon oxidation. Methods of making and using the catalyst composition are also provided, as well as emission treatment systems comprising a catalyst article coated with the catalyst composition.
