We h.0}e prepa.ed a.d ch.0}a.terized a.omica.ly well-defined model systems for ceria.supported Pt-Co core-sh.ll ca.a.ysts. Pt@Co a.d Co@Pt core-sh.ll na.ostructures were grown on well-ordered CeO2(111) films on Cu(111) by ph.sica. va.our deposition of Pt a.d Co meta.s in ultra.igh.va.uum a.d investiga.ed by mea.s of synch.otron ra.ia.ion ph.toelectron spectroscopy a.d resona.t ph.toemission spectroscopy.
