摘要：

This paper describes the phase analysis and oxygen release characteristics of catalytic mixed oxides in the system of CeO2-ZrO2/Al2O3 heated at 800 degrees C. The potential oxygen storage capacity is improved by the addition of ZrO2 to CeO2 in the case of alumina-supported oxides that are easy to prepare by wet impregnation process.
