摘要
氧化铈具有立方萤石结构,储放氧能力与价电子构型,被广泛应用于催化剂等领域。对不同纳米结构的氧化铈制备研究现状做了较系统的概述,并分析了制备不同形貌氧化铈的影响因素。着重介绍了纳米氧化铈在汽车尾气净化和工业废水处理中应用进展,并展望了今后纳米氧化铈材料的研究方向。
Ceria with cubic fluorite structure, oxygen storage capacity and valence electron configuration, is widely used in catalysis. In this paper, current research situation of nanostructured ceria preparation was systematically summarized, and influence factors of preparing ceria with different morphologies were analyzed. Application progress of nano ceria in automobile exhaust purification and industrial wastewater treatment was introduced, and the research direction of nano ceria materials in future was prospected.
