TLDR
In this paper, the difference between supercritical gas adsorption and supercritical vapor adorption is discussed in terms of surface excess adsorptive and absolute adsorbing, respectively.Abstract:
Adsorption-related concepts are explained together with important intermolecular interactions in physical adsorption. The vapor adsorption isotherms on flat surfaces or macropores, mesopores, and micropores are interpreted by multilayer adsorption, capillary condensation, and micropore filling, respectively. Recent studies on capillary condensation in small mesopores are described. The difference between vapor adsorption and supercritical gas adsorption is discussed in terms of surface excess adsorption and absolute adsorption. New aspects of physical adsorption are shown on water vapor adsorption in hydrophobic micropores, quantum molecular sieving effect, and gate adsorption and breathing phenomena on porous coordination polymers.read more
