Special Issue Information

Dear Colleagues,

Adsorption and other interface phenomena are very important in many areas, including chemical engineering, catalysis, environmental protection, separation technology, medicine, biochemistry, electrochemistry, analytical chemistry, and others. Experimental studies in these fields are successfully complemented by theoretical approaches. Applications of molecular simulations and/or mathematical models enable analysis, better understanding, and explanation of interface processes. Such methods also make it possible to design and/or predict new phenomena, materials, and applications. Molecular simulations, e.g., Monte Carlo techniques and molecular dynamics, give direct insight into the mechanism at the molecular level, which is generally difficult to achieve in experimental studies. Theoretical models, for example, of adsorption isotherms or kinetic curves are very useful tools to analyze experimental data. They facilitate quantitative studies and comparison of different data.

This Special Issue welcomes original papers and reviews reporting all the aspects of molecular simulations and/or mathematical models applications in studies on adsorption and interface science. Both strictly theoretical papers as well as those combining experimental results with a theoretical approach are invited.

Abstract: The finite pore volume GAB (fpv-GAB) adsorption isotherm model has been considered as a simple tool which not only enables to analyze the shape of isotherms theoretically, but also provides information about the pore diameter. The proposed methodology is based on the geometrical considerations and the division of adsorption space into two parts: the monolayer and the multilayer space. The ratio of volumes of these two spaces is unambiguously related to the pore diameter. This ratio can be simply determined from N2 adsorption isotherm by its fitting with the use of fpv-GAB model. The volume ratio is equal to the ratio of the adsorption capacities in the monolayer and the multilayer – two of the best-fit parameters. The suggested approach has been verified by the use the series of isotherms simulated inside ideal carbon nanotubes. The adsorption data for some real adsorbents has also been used during tests. The performed studies have proven that diameters estimated with the use of the proposed method are comparable with the geometrical sizes or diameters published by others and based on the application of more sophisticated methods. For pores wider than 3 nm, the relative error does not exceed a few percent. The approach based on the fpv-GAB model, well reflects the differences in pore sizes for the series of materials. Therefore, it can be treated as a convenient tool to compare various samples.
