A review. Gas adsorption is a widely used method for the characterization of mesoporous materials with regard to the detn. of surface area, pore size, pore size distribution, and porosity. Significant progress was achieved during recent years with regard to the understanding of sorption phenomena in narrow pores and the subsequent improvement in the pore size anal. of porous materials, mainly because of the following reasons: (i) the discovery of novel ordered mesoporous materials, such as MCM-41, MCM-48, SBA-15, which exhibit a uniform pore structure and morphol. and can therefore be used as model adsorbents to test theories of gas adsorption; (ii) carefully performed adsorption expts. (iii) the development of microscopic methods, such as the Non-Local D. Functional Theory (NLDFT) or computer simulation methods (e.g. Monte-Carlo - and Mol.-Dynamic simulations), which allow to describe the configuration of adsorbed mols. in pores on a mol. level. However, the influence of pore geometry, geometrical and chem. disorder (as present in many adsorbents) on adsorption, pore condensation and sorption hysteresis, and thus the shape of the sorption isotherm, remains under investigation.
