Abstract:
A three-way catalyst article, and its use in an exhaust system for internal combustion engines, is disclosed. The catalyst article for treating exhaust gas comprises: a substrate; and a catalytic region on the substrate; wherein the catalytic region comprises a platinum group metal (PGM) component, an oxide, and a rare earth metal component; wherein the oxide is an inorganic oxide, an oxygen storage component (OSC) material, or a mixture thereof; wherein the rare earth metal component concentration by element on the surface of the oxide per unit specific surface area of the oxide is 1 μmol/m 2  to 20 μmol/m 2 .

Claim (Index 15):
The catalyst article of  claim 12 , wherein the PGM dispersion is at least 3% after aging at 1000\u00b0 C. for 20 hours under redox conditions when the PGM loading is at least 1%, based on the total weight of the catalytic region.
