Fig. 4: Grand canonical Monte Carlo (GCMC) simulation results of water adsorption.

a The adsorbed water molecules coordinating to aluminum atoms in EMM-8 at low pressure (P/P0 = 0.01). b Aggregation of hydrogen-bonded water molecules in the 12-ring channel at P/P0 = 0.3 from the top view. c The cross-section of the water-loaded channel. The cyan structure refers to the EMM-8 framework. The red and white spheres refer to oxygen atoms and hydrogen atoms of water molecules, respectively.
