英文摘要	the redox features and the catalytic activities of ceria nanowires, nanorods and nanoparticles were comparatively studied. the morphol ogy-depen dent phenomenon is closely related to the nature of the exposed crystal planes. the ceo2 nanoparticles mainly expose the stable {1 1 1} plane on the surface, whereas the rod-shaped nanostructures preferentially expose the reactive {1 1 0} and {1 0 0} planes, giving higher oxygen storage capacity and catalytic activity for co oxidation, although both the ceo2 nanorods and the ceo2 nanowires predominantly expose the reactive {1 1 0} and {1 0 0} planes, the ceo2 nanowires favor to expose a large proportion of active planes on the surface, resulting in a much higher activity for co oxidation than the nanorods.
