| 英文摘要 | Preparation of cerium compounds with different structures and morphology is still a challenge in powder synthesis. CeOHCO3 and CeO2 have received widespread attention because of their potential applications. In this study, a solvothermal method with one-step precipitation was used to synthesize CeO2 with different structures and morphology without use of surfactant. The effects of different experimental conditions on the morphology of CeO2 were investigated. Both X-ray diffraction and SAED patterns revealed that products changed from a single CeOHCO3 phase to a mixture of CeOHCO3 and CeO2. A single CeO2 phase could always be obtained from CeOHCO3 by calcination in air at 673 K for 1 h. Moreover, the morphology of CeOHCO3 was retained. Thus CeO2 particles with different morphology, for example rod-like, prism-like, polygon-like, sphere-like, and cube-like, could be synthesized. Possible mechanisms of phase and morphology evolution are discussed. 漏 2011 Springer Science+Business Media B.V. |
