Cui, Rongrong Lu, Wencong Zhang, Liangmiao Yue, Baohua Shen, Shanshan Template-Free Synthesis and Self-Assembly of CeO<sub>2</sub> Nanospheres Fabricated with Foursquare Nanoflakes Large-scale CeO<sub>2</sub> 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 CeO<sub>2</sub> architecture ca. 100−230 nm in diameter was made up of many nanoflakes with a BET surface of 24 m<sup>2</sup>/g. The possible mechanism for the nanostructures formation was discussed. The catalytic performance of CeO<sub>2</sub> nanospheres and the direct-depositing CeO<sub>2</sub> nanoparticles in CO oxidation were also tested, and the catalytic results were compared and explained by analyzing the exposed planes of the two.
