Catalyst articles having an ammonia slip catalyst (ASC) comprising a blend of platinum on a support with low ammonia storageand a first SCR catalyst, and a second catalyst, such as a diesel oxidationcatalyst, a diesel exotherm catalyst (DEC), a NOx absorber, aselective catalytic reduction/passive NOx adsorber(SCR/PNA), a cold-start catalyst (CSC)or a three-way catalyst (TWC)are disclosed. The catalyst articles can also contain one or two additional SCR catalysts. The catalysts can be present in one of various configurations. The catalytic articles are useful for selective catalytic reduction(SCR) of NOx in exhaust gases and in reducing the amount of ammonia slip. Methods of using the catalytic articles in an SCR process, where the amount of ammonia slip is reduced, are also described.
