CeO2 is widely used in soot catalytic oxidation due to its ample oxygen species and oxygen vacancies.The incorporation of MnOx into CeO2 can cause significant improvement of catalytic activities[1].However,it was found that the catalytic performance of CeO2-MnOx reduced when it was reused.In order to explain this degrading phenomenon,XPS and Raman spectroscopy as powerful tools were utilized to study the soot oxidation via.
