Auger electron spectra of cerium–zirconium mixed metal oxides over a kinetic energy range of 50–1200 eV are presented. The cerium–zirconium metal oxides were prepared via co-precipitation of nitrate precursors. The precipitate compositions were confirmed to ± 5 at. % with x-ray fluorescence and the crystalline structures were determined with x-ray diffraction. The precipitates were formed into 0.1 mm thick specimens and analyzed in wafer form.
