Metal organic framework material, preparation method thereof and use thereof

The present invention relates to a metal organic framework material, a preparation method thereof and use thereof, in particular to a metal organic framework material having a trivalent aluminum ion and a double bud ligand group, a preparation method thereof and use thereof.

Metal-Organic Frameworks (MOFs) are rapidly developing organic-inorganic coordination polymers in recent years. Generally, the metal organic framework material is bonded by a central metal and an organic ligand. Moreover, according to the stacking manner of the central metal and the organic ligand in the metal organic framework material, the metal organic framework material can further distinguish the one-dimensional, two-dimensional and three-dimensional array types.

The metal organic framework material is a porous material. In general, porous materials are often used in gas adsorption, gas separation, catalysis, sensing components, etc. due to their large pores and large specific surface area, especially in the adsorption and storage of carbon dioxide and hydrogen. field. For example, a user can place a porous material at the discharge of carbon dioxide to adsorb carbon dioxide to reduce the environmental impact of carbon dioxide. On the other hand, a porous material can also be used as a hydrogen storage material in place of a method of storing liquefied hydrogen through a steel cylinder.

Metal-organic framework material has structure compared to other kinds of porous materials The advantages of diversity. Therefore, the user can adjust the composition and pore size of the metal organic skeleton material according to his needs. In addition, at the application level, the metal-organic framework material has a high gas adsorption amount at low pressure, and the metal organic framework material also has the advantages of rapid gas absorption and desorption rate, environmental friendliness, and simple synthesis steps. Therefore, metal-organic framework materials are highly anticipated regardless of the adsorption of carbon dioxide or the storage of hydrogen.

In the current metal-organic framework materials, most of them use transition metals (for example, zinc, cobalt, copper, nickel, etc.) as the central metal. For example, MOF-5 consisting of zinc and 1,4-benzenedicarboxylic acid has a carbon dioxide adsorption capacity of about 5 wt% at normal temperature and pressure (298 K/1 bar), but the structure of MOF-5 is extremely sensitive to moisture. It will lose its crystallinity in a low humidity environment. Alternatively, in the case of MOF-177 consisting of zinc and 1,3,5-benzenetribenzoic acid, although MOF-177 can adsorb a large amount of carbon dioxide at a high pressure, the material is disintegrated after being placed in a general environment for three days.

That is to say, the metal-organic framework material centered on the transition metal still has considerable room for improvement in terms of heat resistance or moisture resistance. In addition, because transition metals are less environmentally friendly, additional procedures are required to handle the transition metals used.

Metal organic framework material disclosed in the embodiments of the present invention, and preparation method thereof And its use, because the use of aluminum and double bud ligands to prepare metal-organic framework materials, without the use of transition metals, is therefore more environmentally friendly. On the other hand, the coordination covalent bond between aluminum and the double bud ligand has strong bond energy, and the formed metal organic framework material has a special crystal system, space group and X-ray diffraction spectrum. It has a special peak, so the metal-organic framework material of the present embodiment has a strong structure and can be stably present at a high temperature of 300 °C. Secondly, since the metal organic framework material disclosed in the embodiment of the present invention has the above-mentioned structural characteristics, it has better resistance to moisture.
