摘要：
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. © 2013 WILEY-VCH Verlag GmbH & Co.
