In Search of Scaling Laws in Porous Silica Gels
The role of surface morphology in adsorption processes has been a long standing problem. When adsorption takes place on the interior surface of porous materials (i.e. silica gel, alumina oxide, phase separated glasses, etc.), describing the adsorption process through the thermodynamics of the adsorbates/surface interactions can be complex, making it difficult to interpret the chemical behavior of these systems. These types of porous materials are used in both separation and/or catalytic processes throughout the chemical industry. The selection of a porous material for a specific application is done in part by understanding the interplay between the morphological features of the pore interface and the adsorption and transport properties of adsorbates confined within these pore networks1–3.
