Abstract: A method of making a nanoparticle catalyst composition including: a single heating of an aqueous salt solution comprising a Ce, a Zr, a rare earth dopant, and a transition metal oxide precursor to provide nanoparticles, the nanoparticles have a compositional gradient comprised of a CeZrREO2, where RE is a rare earth, and the outer portion of the nanoparticles has a Ce:Zr ratio different from the inner portion of the nanoparticles. Also disclosed is a nanoparticle-catalyst composition and articles containing the composition, as defined herein.

Abstract: A catalyst body which includes ceria:zirconia and a metal-zeolite, and is substantially free, or free, of tungsten or tungsten compounds, and methods of manufacture. The ceria and zirconia are present with a zirconia/ceria mole ratio of less than or equal to 1.0. The catalyst body is especially useful in NOx reduction applications.
