oxygen [18]. Compared with pure Pr6O11, the reduction peaks of Pr-Zr mixed oxides moved to lower temperatures of 505, 550 and 635 °C (marked as OI, OII and OIII, respectively) after the formation... and aged Pr0.7Zr0.3O2-δ samples. Hydrogen reduction peak shifted to high temperatures due to the crystallization of material. No obvious change has been observed for the oxygen distribution......
