Delta solid solution

Results of XRD indicated that CexPd1-xO2-δ solid solution was formed when the catalysts were calcined at 400-800 ℃,while PdO or metal Pd species re-migrated to the catalyst surface when it was calcined at a higher temperature(1000 ℃).

XRD结果表明,焙烧温度从400℃升高到800℃,有利于CexPd1-xO2-δ固溶体的形成。

XRD results indicated that a Ce_xPd_(1-x)O_(2-δ) solid solution was formed when the catalysts were calcined at 400-800℃,while PdO or metal Pd species re-migrated to the catalyst surface when it was calcined at a higher temperature(1000℃).

XRD实验结果表明,焙烧温度从400℃升高到800℃,有利于催化剂中Ce_xPd_(1-x)O_(2-δ)固溶体的形成,然而焙烧温度升至1000℃时,导致Pd物种从固溶体中析出。
