Abstract
The adsorption structure of water on H-ferrierite at room temperature was i nvestigated with Fourier transform infrared spectroscopy using (H2O)-O-16 a nd (H2O)-O-18. From the isotope shifts, three bands from 3000 to 1500 cm(-1 ) were conclusively assigned to the so-called A, B, C triplet of the hydrog en-bonded complex of water and the Bronsted acid hydroxyl groups on zeolite s. The shifts of other bands also confirmed that the structure of adsorbed water molecules on H-ferrierite is the hydrogen-bonded one. (C) 1999 Elsevi er Science B.V. All rights reserved.
