Title
Effect of chlorine on Ir/CeO2 catalyst behavior for preferential CO oxidation
Abstract

Effect of chlorine on Ir/CeO2 catalyst behavior for preferential CO oxidation is investigated by high-resolution transmission electron microscopy, X-ray photoemission spectroscopy, and diffuse reflectance infrared spectroscopy. The presence of chlorine favors the dispersion of Ir particles. On ceria support, the replacement of the lattice oxygen by chloride ions would produce CeOCl species, which could hinder the formation of hydroxyl groups and carbonate and/or carboxylate species on the ceria surface. These features could explain the decreased activity of the Cl-containing Ir/CeO2 sample.
