The reduction behaviour of a high surface area CeO2-ZrO2 solid solution is compared with that of a high surface area CeO2. It is shown that, upon sintering induced by repetitive reduction/oxidation processes, the temperature of reduction of the solid

Single phase homogeneous CeO 2 –ZrO 2 solid solutions with various compositions were synthesized using a citrate complexation route. Investigation of the sintering behaviour disclosed important modifications of the textural and, in particular, stru

The effects of redox-ageing on the temperature-programmed reduction and dynamic oxygen storage were investigated on two samples of Ce0.6Zr0.4O2 prepared under different synthesis conditions. It was observed that a high-temperature reduction/mild oxid

In relation with the applications of CeO2-ZrO2 mixed oxides in catalysis, new synthetic routes aim at preparing materials with improved performances in terms of durability and high temperature textural and chemical resistance [1]. Barium-doped alumin

A deactivated (aged under redox-cycled model TWC feed-stream) Pd/Ce(0.68)Zr(0.32)O(2) catalyst is remarkably reactivated when subjected to a high temperature oxidising treatment whereas this effect is only marginal for Pd/Al(2)O(3), which indicates t

Evidence is presented that the well-established phenomenon of promotion of Ce0.5Zr0.5O2 reduction by suitable treatment procedures may be controlled by adjusting the conditions; and that such reduction leads to the formation of the pyrochlore structu

By impregnating γ-Al2O3 with cerium/zirconium citrate solutions and subsequent calcination nanostructured CemZr1 -mO2 mixed oxides supported on Al2O3 are obtained, which feature remarkably high oxygen storage even after a calcination at 1373 K for 2

Reduction behaviour and oxygen storage capacity (OSC) of Rh-loaded and metal-free Ce0.5Zr0.5O2 mixed oxides is investigated. It is shown that use of different synthetic methods and the homogeneity of the solid solution strongly affect both the reduct
