Title: Modeling of the hysteresis phenomena in finite-sized slitlike nanopores. Revision of the recent results by rigorous numerical analysis
Abstract: The systematic investigation of the hysteresis phenomena in finite-sized nanopores via the Aranovich-Donohue (AD) lattice density theory (LDFT) is presented. The new reliable quantitative of the adsorption and desorption branch of the hysteresis loop, the formation and movement of the curved meniscus, is As a result, we find that our proposal, which closely mimics experimental findings, can reproduce a rounded shape of the branch of the hysteresis loop. On the basis of the exhausted we proved that the hysteresis loop obtained in the finite-sized slitlike geometry is of the H-1 type of the classification. This fundamental result and the other most results do not confirm the results of the recent studies of et al., whereas they fully agree with the recent lattice due to Monson et al. We recognize that the nature of the loops (i.e. position, width, shape, and the multiple steps) depends on the value of the energy of both the and adsorbate-adsorbent interactions; however, the one is critical for the appearance of hysteresis. Thus, for small adsorbate-adsorbate interactions, the process is fully reversible in the whole region of bulk density. We show that the strong adsorbate-adsorbent produce (also observed experimentally) multiple steps hysteresis loops. Contrary to the other studies of the hysteresis in confined geometry via the LDFT formalism, we constructed ascending and descending scanning curves, which are known from the observations. Additionally, we consider the problem of the of both the obtained adsorption and desorption branches of the computed hysteresis loop in finite-sized slitlike nanopores.
