Abstract: In the paper, the manganese-cerium composite oxide catalysts were prepared by copreeipita-tion.The crystal structure of the catalysts and the desorptlon properties of surface oxygen on the catalysts were investigated by using the methods of TPD-MSand XRD.There are three peaks in the TPD-MSoxygen spectra of Mn2Oa and Mn2O3-CeO2 catalysts.

Key words: Mn2O3, CeO2, Surface oxygen
