通过表面活性剂十八胺和尿素辅助的溶剂热过程，以高产率获得了梭状二氧化铈。采用粉末X射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对晶体结构和形貌进行了表征。初步催化测量表明，梭形CeO2表现出增强的CO氧化活性，这可能归因于其较高的孔隙率和更多的氧空位。 （(C) Wiley-VCH Verlag GmbH & Co. KGaA，69451 魏因海姆，德国，2009 年）
Shuttle-shaped ceria was obtained in a high yield via a surfactant octadecylamine and urea assisted solvothermal process. The crystalline structure and morphology were characterized with powder X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). Preliminary catalytic measurement shows that the shuttle-shaped CeO2 exhibits an enhanced activity for CO oxidation, which may be attributed to its higher porosity and more oxygen vacancies.
