摘要
对近年来国内外CeO2基复合氧化物催化剂的制备方法进行了详细评述,并概述了催化剂的结构和织构特性,以及吸附性和表面酸性等性能。尤其重点介绍了CeO2基复合氧化物在挥发性有机废物、废水处理,以及汽车尾气处理等方面的应用情况,指出了今后研究方向为复合型多功能性纳米氧化物的设计制备与形貌控制及分散性的改善,颗粒成核与生长过程控制,催化过程与机理研究,以及研究成果的规模化生产与工业化应用。
Various preparation methods of CeO2-based composite oxide catalyst developed at home and abroad in recent years were reviewed.The advantages and drawbacks of each method were discussed in detail.The structure,texture,absorbability and surface acidity of the catalyst were also summarized.The applications of CeO2-based composite oxide catalyst in the domains such as volatile organic wastes,wastewater treatment and automobile exhaust treatment were introduced.Future research direction of CeO2-based composite oxide catalyst should be particularly in designing and improving multifunctional nano composite-oxides,controlling morphology and dispersion,studying the mechanism of nucleation and growth,and accelerating the application of CeO2-based composite oxide catalyst products to industry.
