[en] The adsorption behaviour of mesoporous SBA-15 and its plugged analogues (PHTS) were studied in detail. The SBA-15 materials consist of a 2-D hexagonally ordered array of long interconnected pore channels with diameters, which can vary within the range of 4.6 to 30 nm. The PHTS is an analogous materials to SBA-15 containing extra microporous amorphous silica nanoparticles (plugs) within the mesopores thus creating a material with superior mechanical stability. For both types of materials, the adsorption characteristics were evaluated using linear (n-hexane and n-heptane), branched (3-methylpentane), cyclic (c-hexane) and unsaturated (1-hexene) hydrocarbons. For n-hexane, c-hexane, 3-methylpentane and n-heptane the adsorption is mainly controlled by steric effects (size and shape of the molecules), structure of the adsorbed layer and the presence and location of plugs inside the mesoporous channel system. However, the sorption of unsaturated hydrocarbons is additionally governed by the hydrophobic/hydrophilic properties of the adsorbent. Furthermore, the effect of the surface topology in SBA and PHTS on the deposition of transition metal oxides, using the molecular designed dispersion (MDD) technique, was studied by the adsorption behaviour of VO (acac)2 and dimeric TiO(acac)2. In contrast to the SBA-15, the sorption in PHTS materials was mainly controlled by the size of the adsorbate and the sorption temperature. (authors)
