Onset of the Henry constant for supercritical adsorption into carbonaceous porous materials

Article Abstract:

The Henry Law behavior of supercritical adsorbates in carbonaceous pores of different sizes is investigated and the conditions for the applicability of the Henry Law for carbonaceous adsorbents are determined. The result indicates that the porous carbonaceous materials show the presence of Henry Law region for adsorption and that Henry constant is a function of the pore structure of the adsorbent and can be calculated from the pore size distribution (PSD).

Theoretical study of the interaction of molecular hydrogen with PdCu(111) bimetallic surfaces

Article Abstract:

The interaction of molecular hydrogen with two different cluster models of PdCu(111) surface that corresponds to a different formal alloy composition, where both have a single Pd atom in the surface is studied using the density functional cluster model approach. The result exhibits the important role of the electronic or ligand effects in the activity of the PdCu(111) surface sites toward molecular hydrogen.
