Abstract
A metal organic framework glass membrane and a preparation method thereof are provided. The preparation method includes a step of heating a crystalline metal organic framework material to the melting temperature at a rate of 1-15° C./min and then naturally cooling the crystalline metal organic framework material. The crystalline metal organic framework material contains a metal node and a ligand A. The metal node is a zinc ion and/or a cobalt ion and the ligand A is imidazole or phosphoric acid. The metal organic framework glass membrane has a wide range of membrane-forming conditions, and the material thereof can be melted without being decomposed within a control range to form a continuous glass layer with good repeatability.
Claims9
