We now turn our attention to the impact of these weak and strong defects on the adsorption of electrolytes inside the nanopores of the zeolites. Despite the large body of literature on 13 the intrusion of electrolyte solutions in zeolites, there have been very few studies attempting to characterize the composition of the intruded fluid, especially as a function of the intrusion pressure. The behavior most commonly observed is that water molecules penetrate the nanoporous volume at intrusion pressure, potentially followed by electrolyte penetration at a much higher pressure (e.g., around one order of magnitude of increase in case of 2 mol/L NaCl solution in chabazite ). Because previous molecular simulations of electrolyte intrusion in defect-free zeolites showed that ions intrusion is thermodynamically unfavorable in the sub-GPa range of pressure, our goal was to probe electrolyte intrusion in those same zeolites in the presence of point defects.
