| 英文摘要 | the effects of fe promotion were investigated on the activity and selectivity of rh/ceo2 catalyst for the direct synthesis of ethanol from syngas. the catalysts were comprehensively characterized by x-ray diffraction (xrd), n-2 adsorption-desorption, co uptake, h-2-tpr, temperature programmed surface reaction (tpsr), and ft-ir. xrd, co uptake and ft-ir measurements indicated that rh particles were well dispersed. tpsr results revealed that the addition of fe changed co dissociation behavior over the catalysts. ft-ir results showed that fe promoter stabilized both linear carbonyl and gem-dicarbonyl species, which could be responsible for the improved catalytic activity. the interaction between rh and fe species is proposed to play a crucial role in achieving higher ethanol selectivity. |
