| 英文摘要 | The aim of this work is to investigate the microstructure development of cerium oxide nanocrystal, prepared by the microemulsion process, as a function of annealing temperature in air. Combined with the HRTEM and the thermogravimetric-differential thermal analysis (TG-DTA), the XRD patterns reveal that the sample annealed at 623 K is amorphous, and the formation of cerium oxide nanocrystal occurs above 773 K. The local structural and electronic properties in the nanocrystallization process are probed by X-ray absorption spectra (XAS) at the Ce L-3 edge. It is found that the phase structure changes from triclinic to cubic (CeO2), and the electronic structure changes from Ce3+ to Ce4+ upon increasing the annealing temperature. |
