“…The isotherms were described by DA model in the range of the relative pressure up to 0.1 (this range is also widely used in the case of fitting the real adsorption isotherms). During the fitting, the genetic algorithm proposed by Storn and Price [65] was employed (this method was previously successfully used for fitting different data sets [66][67][68][69][70][71][72][73]). The goodness of the fit was estimated using the determination coefficient (DC) defined as [46]:…”

Using simple Metropolis Monte Carlo simulations, the series of virtual porous carbons (VPCs) is generated. During the computations, the carbon EDIP potential is employed. Structures in the series have systematically changing porosity due to the differences in the carbon density. The obtained VPCs are similar to the model proposed by Harris et al., but they do not show its main drawback, because they contain curved fullerene-like sheets, which are interconnected and form one three-dimensional structure. The porosity of VPCs is characterised using a simple geometrical method proposed by Bhattacharya and Gubbins. In order to confirm the reality of the obtained new model carbons and their usefulness for modelling of adsorption phenomena, Monte Carlo simulations of argon adsorption on them are performed. The obtained isotherms are analysed using standard adsorption methods like αs-plots, adsorption potential distributions curves and Dubinin-Astakhov model. The results reveal a close relationship between the systematic changes in the porosity and the adsorption properties. The observed regularities correspond with experimental observations and theoretical studies.

“…Simulated isotherms were fitted by the CMMS model (Eqs. (6) and (7)) using the genetic algorithm proposed by Storn and Price [29] which was previously successfully applied by us for the description of different experimental data sets (see for example [30][31][32]).…”

The influence of the gradual oxidation of carbons on SO 2 physisorption was studied, by comparison of experimental and simulated SO 2 adsorption isotherms. The results confirmed a significant impact of surface groups on the SO 2 adsorption. The simulations also revealed a similar, to that observed experimentally, effect of the increase in the percentage of the smallest micropores on adsorption isotherms. The isotherms were analysed using the CMMS model. The conclusion is that this model seems to be a good and sensitive tool for studying SO 2 physisorption mechanism since a very good qualitative agreement between the experimental and simulated data was observed.

“…Such molecules become the secondary adsorption centres allowing multilayer adsorption. Although the GDW equation was initially derived to describe water adsorption on carbonaceous materials [15], this equation (and/or its modifications) has also been successfully used to fit adsorption isotherms of different gases on different materials [15][16][17], also on CNTs [14]. One of the original GDW equation modifications is the multi-site GDW model (MSGDW) [15].…”

In this paper, new results of calorimetric study on benzene adsorption from the gaseous phase are presented. According to some of recently published reports, the energy of solid-fluid, interactions increases with the rise in carbon nanotube curvature during adsorption. The recent considerations [Chem. Phys. Lett 619 (2015) 219] on thermodynamics of adsorption from aqueous solutions on a series of carbon nanotubes have confirmed this observation. Although comparable "energy-tube diameter" relations for benzene adsorption from the solution and from the gaseous phase are observed, remarkable differences between the mechanisms of the both processes caused by surface heterogeneity are noticeable.
