摘要：

The complex oxides in the CeO2-ZrO2 system were examined for the improvement of oxygen storage capacity in automotive catalysts. The formation of Ce-Zr oxide solid solution improved the thermal stability and activity of CeO2. The Ce-Zr addition enhanced the removal activity for CO, NO(x) and hydrocarbons under dynamic air-fuel ratio condition. The automotive catalyst was designed and developed through research on the oxides in the CeO2-ZrO2 system.
