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.
