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.
