A combination of techniques—mainly immersion calorimetry and adsorption from the vapor phase—provides independent data for the assessment of micropore sizes and their distribution in relation to parameters E0 and n of the Dubinin-Astahhov (D-A) equation. It is shown that carbons described by the Dubinin-Radushkevich (D-R) equation (n = 2) present some heterogeneity, which... Plus

    Summary
    A combination of techniques—mainly immersion calorimetry and adsorption from the vapor phase—provides independent data for the assessment of micropore sizes and their distribution in relation to parameters E0 and n of the Dubinin-Astahhov (D-A) equation. It is shown that carbons described by the Dubinin-Radushkevich (D-R) equation (n = 2) present some heterogeneity, which can be expressed in terms of contributions from true molecular-sieve carbons with n = 3.
