| 英文摘要 | ag-pd/ce0.8zr0.2o2 catalyst was prepared by conventional impregnation and characterized by tpd. the impregnation sequence had great effect on the activity of the catalyst for ethanol and co oxidation. the catalyst sample co-impregnated with ag and pd had the highest activity, and the activity of the catalyst sample impregnated first with pd then ag was higher than that impregnated first with ag then pd. the activity of the catalyst samples for co oxidation was corresponding with the temperature and intensity of co2 desorption peak in co-tpd process. simultaneously, the activity of the catalyst samples for ethanol oxidation was corresponding with the temperature of co2 desorption peak in c2h5oh-tpd process. this indicated that the oxygen species on the catalyst sample prepared by co-impregnation were the most active, and were easier to react with ethanol and co adsorbed on the catalyst surface. besides, the impregnation sequence affected the existing state of ag or pd, and the co-impregnation favored the formation of the oxidation state, but the change of ag state had no relation with co or ethanol oxidation reactivity. |
