- W225219148 abstract "The nature of aluminum species in activated and dealuminated HZSM-20 type zeolites has been investigated by high-resolution one-dimensional solid state 27Al MAS NMR and two-dimensional quadrupole nutation 27Al MAS NMR spectroscopy. Additionally, IR spectra of adsorbed pyridine were recorded and the catalytic activity of samples was tested in the n-hexane conversion. From NMR experiments it is concluded that during activation and following dealumiation different kinds of 4-, 5- and 6-coordinated extraframework aluminum species are formed strongly depending on conditions of activation and dealumination. Namely, after activation monomeric extraframework Al of very high mobility or of high local symmetry (cubic) seems to appear. This sample exhibits the highest catalytic activity suggesting that monomeric or at least low-condensed extraframework Al plays an important role as active species in acid catalyzed reactions." @default.
