英文摘要: A method to synthesize zero, one, and three dimensional (OD, ID, 3D) CeO2 from single crystal cerium formate by a surfactant-free route using H2O, ethanol and ethylene glycol as solvents is shown. OD CeO2 was composed of aggregated particles of 0.2-0.5 mu m. 1D CeO2 was hexagonal rods that were 25-30 mu m in width and more than 500 mu m in length. The pine needle shaped 3D CeO2 was assembled from smooth rods of 1 to 5 mu m diameter and up to 50 mu m length that had CeO2 nanoparticles as building units to give 3D micro/nanocomposite structures with a high BET surface area of 234 m(2)/g. Both 5 wt% CuO/1D CeO2 and 5 wt% CuO/3D CeO2 exhibited high catalytic activities for CO conversion due to the high BET surface area and the facile reducibility of surface CeO2.
