| Abstract: | MnO_x-CeO_2 composites with high surface area were synthesized via a bi-solvent method employing mesoporous silica materials KIT-6 as dispersant.X-ray diffraction,nitrogen adsorption-desorption,ICP,SEM,TEM,electron diffraction and EDS were used to characterize the composition,structure and morphology of the materials.The results indicated that MnO_x-CeO_2 composites with surface area as high as 158 m2/g were obtained by this method. |
