| 中文摘要 | the partial oxidation of methane with molecular oxygen was performed on fe-mo/sio2 catalysts. iron was loaded on the mo/sio2 catalyst by chemical vapor deposition of fe-3(co)(12). the catalyst showed good low-temperature activities at 723-823 k. formaldehyde was a major condensable liquid product on the prepared catalyst. there were synergistic effects between iron and molybdenum in fe-mo/sio2 catalysts for the production of formaldehyde from the methane partial oxidation. the activation energy of mo/sio2 decreased with the addition of iron and approached that of the fe/sio2. the concentration of isolated molybdenum species (the peak at 1148 k in tpr experiments) decreased as the ion concentration increased and had a linear relationship with the selectivity of methane to formaldehyde. the role of fe and mo in the fe-mo/sio2 catalyst was proposed: fe is the center for the c-h activation to generate reaction intermediates, and mo is the one for the transformation of intermediates into formaldehyde. those phenomena were predominant below 775 k. |
