摘要： CeO2的催化性能不仅与粒子大小有关,而且与其形貌密切相关. 本文分析了CeO2的纳米结构和氧化还原特性,综述了CeO2在催化反应中的形貌效应,着重介绍了CeO2的结构和形貌对CO氧化、水气变换和乙醇水蒸气重整制氢以及二元醇脱水反应活性的影响.

Abstract: The catalytic reactivity of CeO2 not only depends on the particle size but al so closely relates to the morphology. The nanostructure and redox characteristic of CeO2 were analyzed in the paper, and the effects of the CeO2 structure a nd morphology on the representative catalytic reactions, including CO oxidation, water gas shift, and ethanol steam reforming, where the morphology-dependent c atalysis is well demonstrated, were summarized.

Key words: ceria, nanostructure, redox, morphology effect, heterogeneous catalytic reaction
