    Abstract

    The effects ofredox-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 oxidation redox cycle can generate temperature-programmed reduction (TPR) profiles featuring a reduction peak at a temperature as low as 537 K. However, despite such favourable reduction behaviour, a strong deactivation of the oxygen storage is observed under dynamic conditions, indicating the limitations of the TPR method for investigation of oxygen storage
