Some remarks on the calculation of the pore size distribution function of activated carbons

Reliable prediction of pore size distribution for nano-sized adsorbents with minimum information requirements

“…3OSI-6OSI, the new proposed method (SHN2) provides excellent prediction for pore size distributions [30], (c) C873Cu [30], (d) Si-100 [35], (e) carbosil ab-1 [30], (f) carbosil ab-4 [30], (g) C873 [30], (h) PICA HP [36], (i) MCM-41 [37], (j) PAN ACF 2 [30], (k) PAN ACF 3 [30], (l) CMC-1 [26], and finally (m) adsorption of benzene on Si-100 [35] when appropriate order of regularization with optimum regularization level have been employed.

“…Fig. 8 shows various measured isotherms for adsorption of nitrogen on different adsorbents [30,[35][36][37]. These real isotherms are used to compare the performances of several available techniques (including ours) for PSD recovery.…”

Adsorption models and structural characterization for activated carbon fibers

“…Wang et al [4] proposed the molecular potential calculation method to investigate the interaction potential of a dispolar SO 2 molecule in graphitic slit pores. Gauden et al [5] developed the Nguyen and Do method, which was utilized to assess the porosity of activated carbon. Stoeckli et al [6] used Brunauer-Emmett-Teller (BET) method and immersion calorimetry to determine the surface area of activated carbon.…”

Bimodal pore size distributions for carbons: Experimental results and computational studies

“…This fact can be explained by conditions of carbon preparation; for example, by creation of the porous structure during activation process [8]. As it was mentioned previously [9][10][11][12][13][14][15][16][17][18][19][20][21], it is amazing that different carbon materials obtained from different precursors have similar (still bimodal) porous structure with the gap between the peaks reflecting to the filling of primary and secondary micropores. Since the recent recipes for the preparation and manufacturing of new carbonaceous adsorbents are still developed, the studies of the methods for porosity characterization should be improved and this improvement should enhance the method sensitivity.…”

“…In recent studies [18] some systematic investigations of the influence of pore structure and the adsorbate-adsorbate and adsorbate-adsorbent parameters on the pore-size distribution functions were performed. Thus, it was shown on the basis of experimental and theoretical data that the change in the shape and behavior of the local adsorption isotherm do not guarantee the differences between the evaluated PSDs except the strictly microporous adsorbents.…”
