Abstract
A diesel exhaust treatment system and method of oxidizing NO to NO at low temperatures are provided. The system utilizes a platinum catalyst on a zirconia-stabilized silica support which oxidizes NO in the exhaust gas to NO and uses the NO in an amount sufficient to oxidize particulate trapped on a particulate filter. The catalyst is preferably pre-treated at a temperature of between about 500 to 650° C. in a NO-oxygen-nitrogen mixture to increase conversion at low temperatures. The catalyst preferably includes an additional oxide component selected from the group consisting of TiO , P O , WO , B O , and Al O or a heteropolyacid component to further increase activity at low temperatures or to decrease platinum loading at the same level of performance.
