英文摘要: Ceria nanospheres with an average size of 320 nm were prepared by a urea-hydrothermal route. The ceria nanospheres had a core-shell structure constructed by nanoparticles and nanosheets that predominantly exposed the vertical bar 111 vertical bar planes. Urea hydrolysis produced CO32- and OH- species as precipitation agent and simultaneously produced ammonia bubbles that acted as a structure-directing agent for the formation of the CeO2 nanospheres. The redox properties and catalytic activity of the CeO2 nanospheres were examined by hydrogen temperature-programmed reduction and CO oxidation, respectively.
