中文摘要	Textural and structure characterizations of Ce1-xMnxO2 (0 <= x <= 1) samples were studied by N-2 adsorption/ desorption, XRD and Raman spectroscopy. The N-2 adsorption/desorption isotherms are found to be IV-type according to BDDT and their related hysteresis loops are H, type. Pore size distribution of the Ce1-xMnxO2 samples is in the mesopores range with RP (max) between 2.5 nm and 3.7 urn. Particle sizes of the samples with both high Mn (x > 0.7) and low Mn (x < 0.3) contents are larger than those with 0.3 <= x <= 0.7. Raman spectroscopic results show that the Cel(1-x)Mn(x)O(2) (x not equivalent to 0, 1) samples contain mixed phases of alpha-Mn2O3 and Ce-Mn-O solid solution, although the presence of alpha-Mn2O3 phase is not detected in the XRD measurement of the samples with x <= 0.7, suggesting that Raman spectroscopy is more sensitive in the structural characterization of Ce1-xMRxO2 samples.
