摘要: The redox features and the catalytic activities of ceria nanowires, nanorods, and nanoparticles were comparatively studied. This morphology-dependent phenomenon is closely related to the nature of the exposed crystal planes. The CeO2 nanoparticles mainly exposed the stable {111} plane on the surface, whereas the rod-shaped nanostructures preferentially expose the reactive {110} and {100} planes, giving higher oxygen storage capacity and catalytic activity for CO oxidation. Although both the CeO2 nanorods and nanowires predominantly expose the reactive {110} and {100} planes, the CeO2 nanowires favor to expose a large proportion of {100} planes on the surface, resulting in a much higher activity for CO oxidation than the nanorods
