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

自1987年作者和同事开发了氧化铈-氧化锆以来，储氧量(OSC)已成为汽车尾气处理中最重要的计量技术之一。从固相化学的角度研究了与CeO2相关的氧化物材料。这是第一个在这一类别中被接受的关于OSC的研究项目，Grant-IN-AID用于科学研究。通过简单的工艺成功地合成了纳米CeO_2和CeO_2相关氧化物。研究了CeO_2、ZO_2等复合氧化物的热稳定性。讨论了CeO_3-Al_2O_3系统的结构转变。

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.
