摘要：

The CeO2-ZrO2 solid solution is the most important oxygen storage/release material for use in automobile catalysts. In particular, the ceria-zirconia solid solution with a pyrochlore structure exhibits the highest oxygen storage capacity (OSC). In this study, CeO2-ZrO2 solid solutions containing Y2O3 were synthesized and their OSCs were measured to clarify the influence of an ordered arrangement of Cc and Zr ions on the OSC. As a result of this study, it is concluded that an ordered arrangement of Cc and Zr ions markedly improves the OSC of CeO2-ZrO2 solid solutions.
