Phases, oxygen release and absorption behaviour was investigated for Zr-Ce-Sn-Pr-O mixed oxides (Zr<sub>2/8</sub>Ce<sub>x/8</sub>Sn<sub>y/8</sub>Pr<sub>(6-x-y)/8)</sub>O<sub>2-z</sub> (x=1.5, 4.5, y=0.5) together with the effect of Cu addition. Major phases of Sn-added samples were similar to those of Sn-free (Zr<sub>2/8</sub>Ce<sub>x/8</sub>Pr<sub>(6-x)/8)</sub>O<sub>2-z</sub> phases, that is, CaF<sub>2</sub>-like λ and C phases for Pr-rich and Ce-rich compounds, respectively. All samples contained a SnO<sub>2</sub> or a Sn phase. When Cu was added, repetitive oxidation and reduction appeared to promote the fine dissolution of Sn and Cu through bulk phases. OSC values of both (Zr<sub>2/8</sub>Ce<sub>1.5/8</sub>Sn<sub>0.5/8</sub>Pr<sub>4/8)</sub>O<sub>2-z</sub> and (Zr<sub>2/8</sub>Ce<sub>4.5/8</sub>Sn<sub>0.5/8</sub>Pr<sub>1/8)</sub>O<sub>2-z</sub> were larger than those of the corresponding Sn-free samples. For the Ce-rich sample, Cu addition improved both the OSC value and its on-set temperature. |
