Design and Synthesis of 3D Ordered Macroporous CeO2‐Supported Pt@CeO2‐δ Core–Shell Nanoparticle Materials for Enhanced Catalytic Activity of Soot Oxidation

Materials with Pt@CeO2-δ core–shell nanoparticles on 3D-ordered macroporous (3DOM) CeO2 are prepared by in situ colloidal crystal templating. 3DOM Ptn@CeO2-δ/CeO2 catalysts, which have both good contact between the solid reactant and the catalyst and a high density of coordinatively unsaturated ceric sites, show high catalytic activities and stabilities for soot oxidation.
