Реферат:
Potential adsorption theory (PAT) suggested by Polanyi back in 1914 is till date one of the most widely used practical methodologies for the treatment of gas adsorption on microporous materials. Here, we extend PAT to the description of the phenomenon of adsorption-induced deformation, which has been recently attracting widespread interest of various scientific communities, from adsorption separations and energy storage to hydrocarbon recovery and carbon dioxide sequestration to drug delivery and actuators. A universal relationship is established between the stress caused by the interactions of guest molecules with the pore walls and the adsorption isotherm. It is shown that in the course of adsorption, microporous solids exhibit a non-monotonic deformation, with contraction at low gas pressures and expansion as the pressure increases. The proposed theory is verified with the experimental data on benzene and n-hexane adsorption on AR-V microporous carbon over a wide range of temperatures. It allows for predicting the adsorption deformation at different temperatures and with different adsorbates and can be applied to a wide class of microporous solids.
