Abstract

The fractal dimension D of a mesoporous silica gel was determined by three independent approaches: (1) adsorption methods based on (a) tiling of the surface with molecules of different cross-sectional area and (b) analysis of the change in measured surface area as a function of the size of the silica particles; (2) analysis of one-step dipolar energy transfer between adsorbed rhodamine B and malachite green; (3) measurements of power-law small-angle x-ray scattering. All three techniques indicate that the surface is extremely rough and irregular, with a fractal dimension D nearly equal to 3.
