摘　　要：CeO2是一种用途极广的稀土材料,可广泛应用于多种研究领域。纳米CeO2具有特殊的性质及应用。因此,纳米CeO2的制备、功能特性和应用研究成为研究的热点之一。综述了不同形貌纳米CeO2制备方法的最新研究进展,着重介绍了CeO2纳米颗粒、纳米棒、纳米管、纳米纤维以及一些特殊形貌纳米CeO2的制备方法和应用前景,并对今后纳米CeO2的研究方向进行了展望。CeO2 is a kind of rare earth materials of extensive uses, and can be applied in various research fields. Being of nanometer size CeO2 shows unique properties and applications. Therefore, research on fabrication, functional properties and applications of CeO2 nanomaterials has become one of the highly ener-gized research fields. The new developments of fabri-cation method of nanometer CeO2 with various mor- phologies was reviewed. Preparation methods and future application of nanometer-sized CeO2 including nanoparticles, nanorods, nanotubes and some special morphologies were discussed. The future research trend of CeO2 nanometerials was also reviewed.
