摘要: The relative effects of Zr4+ and Pr3+/4+ dopants on the structure, redox properties, catalytic performance nanosized ceria was studied. investigated ceria–zirconia ceria–praseodymia (CP) solid solutions were prepared by a modified coprecipitation method, characterized variety techniques, evaluated for soot oxidation. characterization results indicate that CP has more surface bulk oxygen vacancies, sites, lattice mobility, better thermal stability. Besides having low specific area, is active in This activity been attributed to presence which promote adsorption gas-phase formation mobility large numbers species.
