Abstract: Provided are automotive catalyst composites having a catalytic material on a carrier, wherein the catalytic material comprises at least two layers. The first layer is deposited directly on the carrier and comprises a first palladium component supported on a first refractory metal oxide component, a first oxygen storage component, or a combination thereof. The second layer is deposited on top of the first layer and comprises a rhodium component supported on a second refractory metal oxide component and a second palladium component supported on a second oxygen storage component, a third refractory metal oxide component or a combination thereof. Generally these catalyst composites are used as three-way conversion (TWC) catalysts. Methods of making and using the same are also provided.

Abstract: The present disclosure provides a three-way conversion (TWC) catalyst composition, and a catalyst article comprising such a catalyst composition suitable for at least partial conversion of gaseous hydrocarbons (HCs), carbon monoxide (CO), and nitrogen oxides (NOx). Generally, the catalyst article includes a catalyst substrate having a plurality of channels adapted for gas flow, each channel having a wall surface and a catalytic coating on the surfaces or inside the pores of the wall. The catalytic coating generally includes a first washcoat with a platinum group metal (PGM) component and a first refractory metal oxide support and a second washcoat having a plurality of palladium-rhodium nanoparticles and a second refractory metal oxide support.
