摘要:

逆负载型CeO2/CuO催化剂是富H2中优先氧化CO的一种新型催化剂,其活性较传统CuO - CeO2催化剂高。本文综述了CeO2/CuO催化剂的制备方法,着重介绍了逆微乳液法和浸渍法,CeO2/CuO催化剂的尺寸效应和界面效应对催化剂性能的影响作了大胆的猜测,对未来CeO2/CuO催化剂的研究趋势提出了建议,旨在找到CuOCeO2颗粒的最优组合,提高催化剂的选择性和稳定性。

Abstract:

An inverse CeO2/CuO catalyst is a novel catalyst for low-temperature oxidation of CO in H2 rich gaswith higher activity than traditional CuO/CeO2 catalysts. This paper summarizes the preparation methods of CeO2/CuO catalystsincluding inverse microemulsion and impregnation methodsand speculates the influence of size effect and interfacial effect on the performance of CeO2/CuO catalysts. Moreoverit presents the development of CeO2/CuO catalysts in the futurein order to look for the appropriate size of CuO and CeO2 particles and improve selectivity and stability of CeO2/CuO catalysts for CO preferential oxidation.
