摘要：

Spherical Ce(OH)CO3 precursors were prepared via a facile and an efficient hydrothermal process without hard templates. X-ray diffraction (XRD) analysis reveals that the as-synthesized spherical precursors are composed of high-purity Ce(OH)CO3 with a hexagonal structure. After calcination at 573 K for 10 h, the spherical Ce(OH)CO3 precursors decompose into CeO2 nanospheres with a cubic fluorite structure. We also find that morphology of the Ce(OH)CO3 precursors and CeO2 nanospheres is modified significantly as a function of the different surfactants used in the hydrothermal process. When using...
