| 摘 要： | 考察了采用溶胶－凝胶法制备的固溶体Cu0.1Ce0.9Ox和Cu0.1Ce0.6Zr0.3Ox的动态储放氧性能,并通过XRD,TPR,XPS与EPR对样品结构进行了表征.结果表明,新鲜样品Cu0.1Ce0.9Ox的活性优于Cu0.1Ce0.6Zr0.3Ox,老化后,结果相反.采用XRD,TPR,XPS和EPR技术对样品进行了表征.结果表明,Cu-O与Ce-O的相互协同作用提高了Ce基材料的动态储放氧性能.

| Abstract: | The dynamic oxygen storage/release capacity over Cu0.1Ce0.9Ox and Cu0.1Ce0.6Zr0.3Ox prepared by sol-gel method was investigated.The structure of the compounds was characterized by using XRD,TPR,XPS and EPR.The results show that the dynamic oxygen storage/release capacity of ceria-based materials can be improved by synergetic effects between Cu-O and Ce-O. |
