Abstract
A catalyst which is particularly useful in the treatment of diesel exhaust emissions is described. The catalyst comprises a mixture of a supported noble metal and/or chromium component and a bulk first transition series, silver, and/or hafnium component. The supported component catalyzes hydrocarbon conversions and the bulk component catalyzes combustion of carbon particulates in diesel exhaust gases.
