General Scaling Phenomena in Porous Silica Gels as Probed by Saxs and Molecular Adsorption (Tiling)

Abstract

ABSTRACTUsing N2 adsorption (B.E.T.), small angle X-ray scattering and molecular adsorption (tiling) we attempt to describe the internal pore morphology and surface structure of three porous silica gels. The results are analyzed from both a classical euclidian and a fractal scaling viewpoint. The applicability of both viewpoints are shown to be limited but important in describing the structure of porous silicas.
