Abstract
A three-way catalyst for reduced palladium loading is provided. The catalyst includes an inert substrate and a palladium catalyst material coating the substrate. The palladium catalyst material includes a support material formed from one of 10% CeO/AlO, 20% CeO—AlO(20CeAlOy), 30% CeO—AlO(30CeAlOy), AlO, and MOx-AlO, wherein M is one of copper, iron, manganese, titanium, zirconium, magnesium, strontium, and barium. The palladium catalyst material includes a layer of CeOmaterial disposed upon the support material, wherein the layer of CeOmaterial is dispersed on a surface of the support material. The palladium catalyst material includes an active component including a layer of praseodymium oxide particles dispersed across the surface of the layer of CeOmaterial and a layer of palladium particles disposed upon and dispersed across the surface of the layer of CeOmaterial at locations each corresponding to a respective location of each of the praseodymium particles.
