摘要：
The ordered mesoporous CeO2 was synthesized by a hydrothermal method using SBA-15 as a template. The microstructures and performance of the resultant samples were characterized by X-ray diffractometer, N2 adsorption-desorption equipment, transmission electron microscope and thermogravimetry. The effect of the mole ratio of SBA-15 to cerium nitrate on the microstructure and performance of the mesoporous CeO2 was investigated. The oxygen storage/release capacity (OSC) and decolorizing efficiency of the mesoporous CeO2 for acid magenta were also analyzed. The results indicate that the ordered mesoporous CeO2 can be obtained when mole ratio of SBA-15 to cerium nitrate is 1:1, hydrothermal temperature is 80°C and calcining temperature is 500°C. The OSC value of the mesoporous CeO2 was 140.2 μmol/g, which was 1.66 times more than that of CeO2 powder. The decolorizing efficiency of the mesoporous CeO2 for acid magenta was close to 100%, which was greater than that of the powdered CeO2 (60%).
