In the same manner as in the previous works of Cailliez we tune the hydrophobicity of the framework by introducing various amounts of hydrophilic defects, modeled as silanol nests, to qualitatively reproduce the change in adsorption thermodynamics in zeolites as a function of the number and strength of defects. These defects cause the zeolites to become less hydrophobic and more hydrophilic, because the water-zeolite interaction energy increases and becomes higher than the bulk cohesion energy of water (which is of -44 kJ.mol -1 in the TIP4P model). Starting from equilibrated zeolite-water systems, we attempt to introduce electrolyte pairs (or triplets in case of divalent-cation electrolytes) inside the frameworks. Our simulations highlight that silanol defects have very little influence on electrolyte solvation compared to defect-free zeolite frameworks: the thermodynamic work performed to introduce a first electrolyte unit in the system is similar to that in defectfree frameworks. We conclude that point defects, such as silanol nests, do not provide a satisfactory explanation per se for the electrolyte intrusion in zeolites observed in some experimental cases.
