摘要：

This article focuses on the role of mixed oxides in the Ce-Zr-O system, which is important as an excellent promoter for oxygen storage capacity in automotive three-way catalysts. In a model of Pt-alumina catalysts, there is a clear effect of CeO2-ZrO2 solid solution on NO and CO removal activities under dynamic air/fuel conditions. It is suggested that the design and development of automotive catalyst can be realized through research on complex oxides in Ce-Zr-O and related systems. (C) 1998 Elsevier Science S.A.
