摘要：
Deviations of a pore shape from a slitlike one were analyzed for a variety of carbon adsorbents on the basis of calculations of pore size distributions (PSDs) with respect to the pore volume (fv(x)) used for estimation of the PSDs related to the specific surface area (fs(x)) applying several models of pores: individual slitlike pores and mixtures of slitlike and cylindrical pores and gaps between spherical particles. The use of complex pore models allows us to diminish the difference between S-BET and the specific surface area (S-sum) calculated from fs(x). (C) 2004 Elsevier Ltd. All rights reserved.
