| 英文摘要 | Co oxidation at low temperature over pd/ceo(2)-tio(2) catalyst was carried out in the feed containing different contents of water vapor (h(2)o). a positive effect of h(2)o was observed on the catalytic performance of pd/ceo(2)-tio(2) in co oxidation at low temperature. the extent of this effect depends on the content of h(2)o in the feed; with a h(2)o content being 2.5 vol%, the catalyst pd/ceo(2)-tio(2) exhibits the highest stability (longest life time for co oxidation at 80 c). the results of in situ diffuse reflectance infrared fourier transform spectroscopy (drifts) and temperature-programmed reaction (tpreaction) reaction illustrated that h(2)o in the feed supplies sufficient oh groups in the presence of o(2), which can react with adsorbed co on pd species to produce co(2). moreover, h(2)o may also enhance the adsorption of co and suppress the formation of some carbonate species. |
