Abstract

A clean, polycrystalline Ce-metal surface has been successfully produced by using a sputtering and annealing technique on Ce foil. The chemical species conditions at 300 and 120 K have been characterized by XPS. Dissociative chemisorption and reaction occurs to produce a thick layer of Ce₂O₃. N over this Ce₂O₃. Two peaks occur in the O(1s) spectra, at BE 529.6 and 530.3 eV, which are assigned to CeO₂ and Ce₂O₃, respecti eV becomes clearly apparent when CE(IV) forms. The principal species formed are oxides, and no positive evidence was found for the existence of physiso.
