Water adsorption on high silica zeolites, Formation of hydroxonium ions and hydrogen-bonded adducts
Original language description
An in situ high-pressure/high-temperature FTIR spectroscopy technique was used for analysis of water adsorption on ZSM-5 and ferrierite zeolites. Adsorbed water in zeolite channels is present in neutral hydrogen-bonded adducts at low coverage, whereas athigher coverage protonated species H+(H2O)n are formed. The protonated species are easily stabilized in narrow zeolite channels and at higher density of aluminium atoms in the zeolite framework. Moreover, formation of hydroxonium ions is supported by increasing overall pressure. Conditions combining the temperature and pressure for manifestation of both forms of water adsorption have been analyzed.
