摘要
铈锆铝复合氧化物(CeO2-ZrO2-Al2O3)是一种新型的储氧材料,兼有储氧材料和氧化铝共同的优点。介绍了铈基储氧材料的发展历程及铈锆铝储氧材料的形成,归纳总结了浸渍法、共沉淀法、溶胶-凝胶法、微乳液法和机械混合法等方法制备的铈锆铝储氧材料研究成果及各方法的优缺点,并对今后铈锆铝储氧材料的主要研究方向和工业化问题进行了展望。
CeO2-ZzO2-Al2O3 compound is a new type of oxygen storage material （OSM）, which combines both advantages of OSM and Al2O3. In this paper, the development of CeO2-based oxygen storage materials including CeO2-ZzO2-Al2O3 compound is reviewed. The research progress and characteristics of the synthetic methods for CeO2-ZzO2-Al2O3, such as impregnant method, co-precipitation method, sol-gel method, micro-emulsion method and mechanical milling method, are summarized. Finally, the research and industrialization trend are also discussed.
