| 英文摘要 | in this study, ir-fe/sio2 catalyst was prepared by coimpregnation and investigated for preferential oxidation of co under the presence of hi. it was found that the presence of h-2, even in a slight excess, led to a large increase in the reaction rate for co oxidation over the ir fe/sio2 catalyst, which was quite different from the case of ir/sio2. to reveal the promotional role of fe associated with the presence of h-2, quasi in situ mossbauer spectroscopy, in combination with in situ drifts and microcalorimetry, was employed. the results showed that the relative amount of fe2+ increased with increasing h-2 concentration in the reaction stream, well consistent with the trend of reaction rate for co conversion, strongly suggesting that fe2+ is the active site for oxygen activation. h-2 promoted co oxidation mainly via maintaining a substantial amount of fe existing as fe2+. |
