摘要：

The oxygen storage capacity of cerium oxide (CeO2) Containing zirconium oxide (10, 20, 30, 50, 85, 93 mol%) (ZrO2) was studied by measuring temperature programmed reduction. On increasing the ZrO2 content, the reduction reaction at 530-degrees-C appeared stronger, and that at 800-degrees-C weaker. A 50CeO2-50ZrO2 mixture comprised tetragonal ZrO2(CeO2) and cubic CeO2(ZrO2). Whereas the 15CeO2-85ZrO2 mixture comprised a phase of tetragonal ZrO2(CeO2) which gave a maximum OSC peak. Characterization of the as-prepared and TPR resulting samples were carried out by XRD and SEM.
