Abstract

Rugby-ball-like CeO2 hierarchical porous structures have been successfully synthesized by a simple template-free hydrothermal method using CeCl3·7H2O as cerium, NH4HCO3 as precipitator and ethanediamine as surfactant. X-ray diffraction (XRD) inferred that the synthesized CeO2 microstructures exhibited a fluorite cubic structure. Moreover, the as-prepared CeO2 samples have a rugby-ball-like hierarchical porous structure assembled by numerous nanorods with a small diameter, and the oxygen vacancies and Ce3+ ions exist in the surface of samples. There is a red-shifting in the band gap of the material compared to bulk one, which is mainly attributed to the influences of the Ce3+ ions, oxygen vacancies and the morphology of the material.
