XPS Study of CeO2/Al2O3 film

    Graphical Abstract
    • Abstract
  • The redox capacity of CeO2/Al2O3 thin film which was prepared by sol-gel method has been investigated by X-ray Photoelectron Spectrascopy (XPS). The results showed that the thin film was easier to be reduced and re-oxidized than pure CeO2 powder. The key role played by oxygen vacancies which were created from the interaction between CeO2 and Al,O, was also discussed.
