Abstract

The microporosity of chromia- and TiO2-pillared clays differing in pillar d. was explored. Nitrogen adsorption data detd. at very low relative pressures were used. These data were analyzed by the as method and the BET, Langmuir, Dubinin-Radushkevich and Dubinin-Stoeckli approaches. The applicability of these methods for detn. of the PILCs' microporosity was studied. The surface area calcd. by the as method can be considered as a total surface area of the materials studied. The BET method underestimates, whereas the Langmuir approach overestimates, the total surface area of these solids. The Dubinin-Radushkevich method can be applied only to characterize textural features of PILCs exhibiting homogeneously distributed narrow micropores (
