Abstract

This paper describes a new route to synthesizing non-stoichiometric oxide catalysts and ideal oxide supported catalysts by nanocrystalline processing. By dc-magnetron sputtering from a pure or mixed metallic target, followed by slow oxidation of the metallic clusters, nanocrystalline CeO_2-x, La-CeO_2-x, and Cu-CeO_2-x catalysts were generated and collected effectively on a ground shield modified substrate. Structure and thermal stability of these materials were investigated by X-ray diffraction and X-ray photoelectron spectroscopy. Novel ultrahigh dispersion of Cu on CeO_2-x was achieved by surface segregation approach to design unique supported catalyst.
