Ferrisilicate molecular sieve with the MCM-22 structure, has been carried out by different methods, using HMI as a source of organic template, different silica and iron sources. Fe-MCM-22 zeolite has been synthesized as a unique phase for Si/Fe=16. The trivalent elements isomorphous substitution was demonstrated by X-ray powder diffraction, BET, H2 temperature programmed reduction (TPR), infrared spectroscopy (FTIR), x-ray photoelectron spectroscopy (XPS). A comparison of Si/Fe ratios determined by chemical analysis and XPS method were studied. Calcination leads to complete removal of the template. During this process a significant fraction of iron is dislodged to extraframework positions. H2TPR indicates that the presence of different forms of iron. XPS spectra of N1s binding energies showed two types of sites: Brönsted and Lewis.
