| 英文摘要 | the influence of extra-framework al via alcl3 deposition on the structure of the active fe sites in fe/zsm-35 was investigated by si-29 mas nmr, uv-visible diffuse reflectance spectroscopy, infrared spectroscopy, uv raman spectroscopy, and fe-57 mossbauer spectroscopy combined with catalytic decomposition of n2o. it is found that high-temperature treatment considerably modifies the iron speciation. uv-visible diffuse reflectance spectra and in situ infrared spectra of no adsorption show that a significant amount of clustered and cationic fe species is transformed into extra-framework fe-o-al mixed oxide species by high-temperature treatment. uv raman spectra and fe-57 mossbauer spectra suggest the generation of a binuclear fe site stabilized by extra-framework al species with a feature raman band at 875 cm(-1), which is associated with the high activity of n2o decomposition. a possible explanation is that the addition of extra-framework al species is beneficial for the formation of binuclear active fe sites bound to extra-framework al.
