摘要
概述了汽车尾气净化指标的各种要求,指出了CeO2-ZrO2(CZ)粉体在汽车尾气净化三效催化剂应用的原理、优点及最新研究成果。介绍了介孔材料的制备方法,详细分析了介孔CZ材料的判断依据。将近十几年来有关CZ介孔材料的研究历史和文献结果进行了仔细分析和对比,并将文献报道的产物划分为三大类,指出了CZ介孔材料较难合成的原因,分析了解决的途径和原理,介绍了本课题组提出的一种新的合成介孔CZ的思路。
Abstract The standards for automobile exhausts controlling are reviewed. The basic theory, priority and the newly published results of CeO2-ZrO2 （CZ） powders for the exhausts clearing usage are included. The preparation methods for mesoporous materials are introduced and the determining standards for the meso-CZ are analyzed detailed- ly. The progress in preparing meso-CZ in the near decades is carefully analyzed and the cited results are categorized in- to three main types. The difficulties in preparing meso-CZ are listed, the possible solution and mechanism are pro- posed, and a novel idea to prepare mesoporous CZ materials is introduced.
