摘　　要：有序介孔CeO2材料以其在汽车尾气净化、有机废水处理、固体氧化物燃料电池、光学器件等领域的巨大应用前景成为近几年的一大研究热点。本文基于软模板与硬模板法两大分类,综述了有序介孔CeO2材料的制备方法,对其合成机理进行了阐述,重点概括了该材料在催化领域的应用,并对其今后的研究趋势进行了展望,提出孔道结构的稳定性还有待改进,掺杂离子对其介孔结构影响值得进一步研究,走向器件化亟需深入探索。Ordered mesoporous CeO2 has attracted considerable attention due to its tremendous applications in the areas such as purification of automotive exhaust, organic waste water treatment, solid oxide fuel cells and optics devices. The development of ordered mesoporous CeO2 was reviewed. The preparation methods were introduced from the point of view of soft--templated and hard--templated approaches, and the synthetic mechanism was elaborated in detail. Potential applications of ordered mesoporous CeO2 particularly in catalysis area were summarized. The future research perspectives, including the stability of meso-- structure, the effect of doped ions, and the fabrication of thin film device, still need further investigation.
