Krypton adsorption on (0001) graphite pre-plated with cyclohexane
Résumé
Krypton physisorption on (0001) graphite pre-plated with cyclohexane (C 6H12) also physisorbed has been studied between 71 and 83 K by means of classical volumetric methods. Krypton adsorption is strongly hindered by preadsorbed C6H12, and becomes significant at pressures definitely higher than on bare graphite. In the first layer range, a partial displacement of the preadsorbed C6H12 film by krypton adsorption, according to a first order phase transition process, was assumed, as well as 3D C6H12 crystallites formation and partial miscibility of the 2D phases. At higher coverages krypton adsorbs on itself.
