Streszczenie: By means of ATR FTIR and high temperature diffusive reflectance FTIR investigated the structure of o zeolite H-ZSM-5 at 25 and 350 C temperature treatment in inert atmosphere (in situ). Spectral changes were observed when H-ZSM-5 mixing with Al2O3 and modifying with Mg and Rh salts. Absorption bands of free and associate OH groups on the zeolite surface were identified after water removal and zeolite modification. Using quantum chemical calculations theoretical spectra of the zeolite models isolated or bonded OH surface groups found.
