title = "On the activity of cationic Au species during the preferential Co oxidation on low content Au/Ceo2 catalysts",
abstract = "In the case of selective oxidation of CO, cationic Au species on Au/CeO2 catalysts are highly active. Catalysts having 0-1.3 Au wt % were prepared by the deposition-precipitation method and were dried at 80°C and calcined in air at 400°C. The activity depended on the Au content and on the reaction conditions used. The presence of Au as cationic species depended on the method of preparation and on the Au content. Only cationic species were observed in the case of low Au content (≤ 0.4 wt %). Catalysts having Au content around 0.8-1 wt % had both nanoparticles and cationic species. High Au content samples (≥ 1.3 wt %) had only nanoparticles and no CeO2 lattice expansion was observed in this case. All our catalysts were highly active in the PROX reaction in the presence of 50% H2 at 80°-110°C. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).",
