Formation of Pd-Ce intermetallic compounds by reductive metal-support interaction

The formation of Ce-Pd intermetallic phases by reductive metal-support interaction of Pd/CeO2 thin film and powder systems. For the powders, the Pd-rich CePd5 is observed at lower temperatures than CePd3 (1020 K vs. 1130 K), whereas both phases appear at lower temperatures of 873 K in the case of the thin film.325
