摘要The Fe - substituted mordenite was hydrothermally synthesized and characterized by XRD, FT IR, TPR and XAFS. The FT - IR spectra and powder X - ray diffraction patterns showed that the as synthesized samples were well crystalline mordenite and the incorporation of Fe into the framework of zeolite was verified. The local structure of Fe in the framework was characterized by XAFS. The pre - edge peaks appeared in the XANES spectra of (Si, Fe) - MOR suggested the tetrahedral structure of Fe, and confirmed the incorporation of Fe into the framework of zeolites. The results calculated from the XAFS indicated that the Fe had a tetrahedral structure with an Fe-O distance of 0.188 similar to 0.189nm, which accorded well with the stable structure of as - synthesized zeolites. The peaks at 0.320nm and 0.338nm were assigned to the coordinated Si atoms in the framework.
