Abstract
Changes in cyclohexane and water vapour adsorptions and enthalpies of immersion for a series of progressively oxidized porous carbons have been measured. The adsorption and thermal results are discussed in terms of the pore-filling mechanism of Dubinin and the influence of surface oxides on the water adsorption is examined. It is concluded that the important enthalpic contribution for cyclohexane comes from pore-filling while for water, the hydrogen bonding-like interaction around surface oxide sites plays the major role.
