%X Large-scale CeO2 spherical architectures composed of numerous nanoflakes have been controllably prepared through a simple hydrothermal reaction without any template. The products were characterized with X-ray diffraction, nitrogen adsorption−desorption experiments, transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM). It was found that the CeO2 architecture ca. 100−230 nm in diameter was made up of many nanoflakes with a BET surface of 24 m2/g. The possible mechanism for the nanostructures formation was discussed. The catalytic performance of CeO2 nanospheres and the direct-depositing CeO2 nanoparticles in CO oxidation were also tested, and the catalytic results were compared and explained by analyzing the exposed planes of the two.
