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.
