[hal-01087717] Activation and structural and adsorption features of activated carbons with highly developed micro-, meso- and macroporosity

Three sets of activated carbons (ACs) were pre-pared with the same precursor but activated differently (by CO2or water vapour) with various burn-off levels. The ACs demonstrate increased deviation of the pore shape from the slitshaped model with increasing burn-off and contributions of pores of different sizes depending on the activation type. Significant re-arrangement of adsorption complexes, espe-cially of the Van der Waals type characteristic for nonpo-lar or weakly polar adsorbates (H2,CH4,CH2Cl2,CHCl3),occurs in both micropores and mesopores of ACs with de-creasing temperature. The behaviour of their mixtures with water and DMSO can strongly differ from that of individual adsorbates.
