Abstract

This paper presents the differential heat of water adsorption on the AgZSM-5 zeolite at a temperature of 303 K. A correlation between the adsorption-energy characteristics is found and the molecular mechanism of water adsorption in the AgZSM-5 zeolite is revealed in the entire filling region. The stepwise nature of the heat of water adsorption is revealed. It has been determined that water molecules with silver cations in zeolite form a high-energy nano-ion-molecular complex in the first coordination sphere. It was also found that water molecules are adsorbed only in the first and second coordination spheres corresponding to saturation.
