Study of synthesis and structure control of complex oxide having exhaust-gas purifying performance

自1987年笔者与同事共同开发出氧化锆-氧化锆复合材料以来，氧储存容量（OSC）已成为汽车尾气处理中最重要的金属技术之一。从固体化学的角度对氧化铈相关氧化物材料进行了研究。这是第一个在科学研究资助类别中接受的关于海洋盐含量的研究项目。用简单的方法成功合成了纳米二氧化铈及其相关氧化物粉末。研究了氧化铈及其它复合氧化物的热稳定性。讨论了氧化铈-氧化铝体系的结构转变。

Oxygen storage capacity (OSC) is now one of the most impotant metrial technology in automotive exhaust treatment, since the ceria -zirconia was developed by this author and coworkers in 1987. The ceria related oxide materials were studied in the viewpoint of solid state chemistry. This is the first accepted research project about OSC in this category, GRANT-IN-AID FOR SCIENTIFIC RESEARCH. Successful synthesis of nanopowders of ceria and ceria related oxides via simple process. The thermal stability of ceria zirconia and other complex oxides was studied. The structural transformation was discussed for ceria alumina system.
