Homogeneous and Heterogeneous Micropore Structures in Carbonaceous Adsorbents—Twenty Years Later

Characteristic adsorption functions and the surface structure of solid adsorbents

“…The DR interpretation implies linearizing the data in the form (13) ln(n s ) vs ln 1 P r 2 , as shown in Fig. 6a.…”

“…However, for these complex investigations, models or theories of adsorption are required that also reflect the structure of adsorbents. Fortunately, there are many methods for realizing this aim, especially those from which pore-size distribution and/or the energy distribution functions can be calculated [10][11][12][13][14]. Recently Tóth has proposed a thermodynamic model of physical adsorption [15].…”

Corrected thermodynamic description of adsorption via formalism of the theory of volume filling of micropores

“…The theory of volume filling of micropores of Dubinin et al [9,10] is still one of the most important tools for the evaluation of the parameters of adsorbents. Although it is thermodynamically inconsistent [11][12][13][14], this theory has been widely applied, modified, and extended on heterogeneous porous structures [15][16][17]. The fundamental paper by Chen and Yang [18] showed that the fundamental equation of the theory of volume filling of micropores (TVFM), called the Dubinin-Radushkevich equation (or in the generalized form the Dubinin-Astakhov equation), can be derived from statistical thermodynamics.…”

Thermodynamical model and prediction of gas/solid adsorption isotherms

“…The pore-filling theory (adsorption on carbons) led to exact definitions of the pore-size distribution (PSD) functions [18][19][20], which have been corrected and developed by Terzyk [21] and Gauden [22]. Collected works of these up-to-date models and theories are to be published in 2002 [23].…”
