Elastic behavior of all-silica Ferrierite: HP-induced hydration of a \u201chydrophobic\u201d zeolite

The HP structural investigations of an all-silica ferrierite showed that, in both experiments, the penetration of water and alcohols is achieved at very low pressure. All the species entering the pores are arranged in chains running along the central axes of the channels. The interactions among the extraframework molecular species and the framework oxygen atoms are very weak, due to the hydrophobicity of the framework walls
