摘要：

XPS experiments on alumina supported Pt-CeO2 catalyst have shown AlCeO3 formation during the initial treatment. This aluminate is very stable and remains unaffected by further treatment. TPR was used in tandem to characterize the reducibilities of both platinum and several rare earth oxides. The appearance of a new peak in the TPR profile reveals that there is a preferential interaction between the rare earth oxide and the platinum.
