Pure metallic platinum nanocrystallites with uniform diameter, confined in the pore channels of mesoporous zirconia, have been synthesized by a new ion- exchange reaction followed by in-situ reduction. Such a nanostructured platinum–zirconia mesoporous composite material is demonstrated to be an efficient catalyst for the oxidation of CO. Incorporation of ceria into the zirconia walls is shown to lead to a material with promise as a high-performance exhaust-conversion catalyst with immediate activation of the catalyst on engine start-up.
