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.

自作者及其同事于1987年开发氧化铈-氧化锆以来，储氧能力（OSC）现已成为汽车尾气处理中最重要的金属技术之一。从固态化学的角度研究了氧化铈类氧化物材料。这是第一个被接受的关于OSC的研究项目，在这个类别中，资助科学研究。通过简单的工艺成功合成了氧化铈及其相关氧化物的纳米粉体。研究了氧化铈、氧化锆等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。
