摘要：

(Chemical Equation Presented) Cores to celebrate: At 370°C, Pt@Cu core-shell nanoparticles rapidly alloy but the reciprocal core-shell nanoparticles, Cu@Pt (see STEM images, left: Cu spectral map; middle: Pt spectral map; right: bright-field image), are kinetically stabilized and show high activity and selectivity for NO reduction. © 2005 Wiley-VCH Verlag GmbH & Co.
