ABSTRACT
A synergy between a partially reducible oxide (PRO) and metal particles has been explained in part by the assistance of the metal in facilitating PRO reduction, such that H2O molecules can be activated on the support; the subsequent water-gas shift (WGS) catalysis may then proceed either by a redox mechanism or associative mechanism involving either formates or carboxylate species. In this contribution, three lanthanide oxides were prepared by the urea precipitation method and compared to ceria as a support for Pt for WGS.
