| Abstract: | The oxygen storage material is a key material which has been widely used in modern three-way catalyst for purification of automobile exhausts.In this paper some domestic and overseas development and investigation on oxygen storage materials were described.The modification for CeO2-based oxygen storage materials of solid solutions was emphasized in this study,the transition or rare earth metal elements was introduced into CeO2 lattice and solid solutions were formed,which hugely improved oxygen storage performance and thermal stability performance of CeO2-based oxygen storage materials.It promoted the practical application of CeO2-based oxygen storage materials extensively. |
