摘要：

Three kinds of REO modified CeO 2 ZrO 2 solid solutions were prepared by co precipitate method.TPR and XRD measurements have been used to characterize the effect of REO on the thermal stability and oxygen storage properties of CeO 2 ZrO 2 solid solutions,comparison being made with unmodified CeO 2 ZrO 2 solid solutions.The results indicated that the addition of REO to CeO 2 ZrO 2 solid solutions obviously improved the oxygen storage properties of the three kinds of solid solutions calcinated at 773K.Except for Zr rich solid solutions,the modified CeO 2 ZrO 2 solid soltuions calcinated at 1173K show higher thermal stability and oxygen storage properties than unmodified solid solutions.
