Abstract: Catalytic materials, and in particular, rhodium-containing catalytic materials for exhaust gas purifying catalyst composites are provided herein. Such materials comprise multimetallic Rh-containing nanoparticles, which are present primarily inside aggregated particles of a support (such as alumina). Such catalytic materials can exhibit excellent conversion of hydrocarbons and nitrogen oxides.

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.

Abstract: Catalysts that improve carbon monoxide (CO), hydrocarbon (HC), Catalyst outlet temperature and speed traces of and nitrogen oxides (NOx) light-off performance are provided. A catalyst composite for combustion engines, as provided herein, comprises a carrier and a first layer comprising a catalytic material on the carrier, the catalytic material comprising a palladium component supported on both a ceria-praseodymia-based oxygen storage component and a ceria-zirconia-based oxygen storage component, wherein the first layer is essentially free of alumina. The catalytic material is effective to substantially simultaneously oxidize carbon monoxide and hydrocarbons and reduce nitrogen oxides.

Abstract: Catalytic materials for exhaust gas purifying catalyst composites comprise platinum group metal (PGM)-containing catalysts whose PGM component(s) are provided as nanoparticles and are affixed to a refractory metal oxide, which may be provided as a precursor. Upon calcination of the catalysts, the PGM is thermally affixed to and well-dispersed throughout the support. Excellent conversion of hydrocarbons and nitrogen oxides can advantageously be achieved using such catalysts.
