Abstract: A catalyst composition comprises a particulate support and catalyst nanoparticles on the particulate support. The catalyst nanoparticles comprise an alloy of platinum and palladium in an atomic ratio of from about 25:75 to about 75:25 and are present in a concentration of between about 3 and about 10 wt% weight percent of the catalyst composition. The catalyst composition has an X- ray diffraction pattern that is substantially free of the (311) diffraction peak assignable to Pt x Pd 1-x , where 0.25 ≤ x ≤ 0.75.

Abstract: A process is described for producing a powder batch comprises a plurality of particles, wherein the particles include (a) a first catalytically active component comprising at least one transition metal or a compound thereof; (b) a second component different from said first component and capable of removing oxygen from, or releasing oxygen to, an exhaust gas stream; and (c) a third component different from said first and second components and comprising a refractory support. The process comprises providing a precursor medium comprising a liquid vehicle and a precursor to al least one of said components (a) to (c) and heating droplets of said precursor medium carried in a gas stream to remove at least part of the liquid vehicle and chemically convert said precursor to said at least one component.
