汽车尾气催化剂用储氧材料的研究进展

he research progress of automobile exhaust catalyst with oxygen storage materials is discussed in this paper, and the different types of oxygen storage materials are detailed . The Quaternary or multiple solid solution oxide oxygen storage material with excellent high temperature and aging resistance and oxygen storage performance can meet the most stringent European Ⅴ emissions standards, which is an important direction of the oxygen storage material development in the future, and with broad prospects.
