Abstract:
Described are catalyst compositions, catalytic articles, exhaust gas treatment systems and methods that utilize the catalytic articles. The catalyst composition comprises a washcoat including a zeolite, refractory metal oxide support particles, and a platinum group metal supported on the refractory metal oxide support particles. Greater than 90% of the refractory metal oxide particles supporting PGM have a particle size greater than 1 μm and a d50 less than 40 microns.
