Abstract

The influence of the atom-wall interaction on adsorption in 4 nm cylindrical pores has been studied using Grand Canonical Monte Carlo simulations. A model with smooth ideal walls has been used to remove the influence of heterogeneous structures. It has been found that the layering transition pressures strongly depend on the atom-wall interaction. The interaction also defines the number of layers adsorbed below the capillary condensation pressure. It has been observed that the stability of adsorbed layers is modulated by the strength of the atom-wall interaction.
