Three sphere packing (SP) and three particle packing (PP) silica xerogels, two silica aerogels (AERs), one all-silica mesoporous molecular sieve (MMS), one all-silica molecular sieve (MS), two high Si/Al relation molecular sieves, and an extremely high Si/Al relation molecular sieve were carefully studied with SEM, TGA, SAXS, DRIFTS, and adsorption of nitrogen at 77 K and carbon dioxide at 273 K. The study of different amorphous, ordered, and crystalline silicas, applying numerous powerful and complementary experimental methods and a proper theoretical methodology, is, by itself, an original approach that allows the recognition of the similar features exhibited by the surface of these materials. With the help of SEM, TGA, SAXS, and DRIFTS, it was found that the SP, PP, and AER samples present a complicated pore size distribution composed of micropores and mesopores formed by the agglomeration of primary nanoparticles.
