In the field of airship, water vapor is a resource with very good use value, and the water vapor is collected by high-quality MOFs, so that the MOFs material is required to have water stability to ensure that the MOFs material is not decomposed when meeting water and hydrophilic and can efficiently absorb the water vapor.
The stability of the MOFs is generally determined by pairing and constructing a hard alkali ligand and a hard acid metal ion or a soft alkali ligand and a soft acid metal ion, and the metal organic framework material has better stability and ensures the normal operation of material water collection. Otherwise, the coordination bonds in the material can be destroyed by water molecules, so that the material no longer has a complete structure.
