Research output: Contribution to journalArticlepeer-review


We presented a new characterization method for surface area, pore volume and pore size distribution of a solid based on the recently proposed concept of absolute accessible volume (Prasetyo et al. 2018). This method provides a coherent framework to characterize nanoporous atomic models. It gives an advantage over earlier methods in the sense that the accessible properties, volume, surface area and pore size distribution, follow a single set of rules that are based on the energy of interaction between a molecular probe and the solid. The derived parameters result in the Henry constant and the differential heat of adsorption approaching zero at extremely high temperatures as physically demanded, and we illustrated this new method with a range of porous solids.
