摘　　要：采用液相法中的沉淀法、溶胶-凝胶法和电化学法制备了纳米CeO2,针对不同的制备方法,通过XRD、TEM、SAXS以及SEM进行了分析,从制备的纳米粒子形态、制备工艺、特点以及发展前景上进行了比较。Nanometer cerium (IV) oxide (CeO2) powders were prepared by means of different methods, Sol-Gel method, precipitation method and electrochemical method. The powders were analyzed by using X-ray diffraction (XRD), transmission electron micrograph (TEM), scan electron micrograph, small angle X-ray scattering (SAXS). The powders on different methods were compared from the shapes of particles, preparation techniques. The features of every preparation method were introduced and its developmental trend was also p...
