| 英文摘要 | the effect of introducing extra-framework ga on the local structure of the metal sites in fe/zsm-5, resulting in enhanced reactivity toward n(2)o, was investigated using a combination of raman and x-ray absorption spectroscopies. the raman spectra indicate an increased abundance of oxo- and/or hydroxo-bridged diiron sites, whereas the fe k-edge xanes reveals more extensive reduction of fe(iii) to fe(ii). curvefits of the exafs at both the ca and fe k-edges are consistent with heterometallic oxo-clusters containing both ca-fe and fe-fe paths. the spectroscopic evidence suggests a tetranuclear [fe(2)ca(2)o(4)(2+)] core, possessing an open dicubane structure. |
