Alterations of fluid phase transitions in porous materials are conventionally employed for the characterization of mesoporous solids. In the first approximation, this may be based on the application of the Kelvin equation for gas-liquid and the Gibbs-Thomson equation for solid-liquid phase equilibria for obtaining pore size distributions. Herein, we provide a comparative analysis of different phase coexistences measured in mesoporous silica solids with different pore sizes and morphology.

Article Synopsis
  • Porous solids often have structural disorder that impacts how substances behave in their pores, making it crucial to understand these properties for practical applications.
  • This study examines recent advancements in understanding how phase states relate to geometric disorder in nanoporous materials through a simplified model of disordered pore networks.
  • The authors link their theoretical predictions with experimental data, providing insights into phase transitions in these materials and suggesting ways to enhance gas sorption and thermoporometry techniques for characterizing porous substances.

Nitrogen sorption and melting and freezing of water in a small pore size mesoporous glass with irregular pore structure is studied. The analysis of the experimentally obtained data is performed using the recently developed serially connected pore model (SCPM). The model intrinsically incorporates structural disorder by introducing coupling between nucleation and phase growth mechanisms in geometrically disordered mesopore spaces.
