Embodiment 1

[0028] Example 1: Synthesis of Metal Organic Frameworks

[0029] Dissolve 0.048g of copper nitrate trihydrate in 1mL of water, dissolve 0.025g of pyromellitic acid in 4mL of water, mix the obtained copper nitrate trihydrate aqueous solution and pyromellitic acid aqueous solution, and stand for reaction at 60°C for 3 days, and then the obtained The reaction product was cooled to room temperature and subjected to suction filtration. During the suction filtration, 5 ml of ethanol was used to wash three times. The resulting filter cake was dried at 60° C. for 24 hours to obtain 0.031 g of the product, with a yield of 67.4%.

[0030] Structural characterization and performance tests were performed on the product obtained in Example 1.

[0031] refer to figure 1 , figure 1 This is the shape of the product under a microscope. It can be seen through observation that the product is a dark green crystal with a crystal length of about 0.201 mm.

[0032] refer to figure 2 , figure ...

Embodiment 2

[0051] Example 2: Synthesis of Metal Organic Frameworks

[0052] Dissolve 0.960g of copper nitrate trihydrate with 2mL of water, dissolve 0.600g of pyromellitic acid with 8mL of DMF, mix the obtained copper nitrate trihydrate aqueous solution and pyromellitic acid DMF solution, and let it stand for reaction at 60°C for 3 days, and then dissolve the obtained The reaction product was cooled to room temperature and subjected to suction filtration. During the suction filtration, 5 ml of ethanol was used to wash three times. The resulting filter cake was dried at 60° C. for 24 hours to obtain 0.628 g of the product, with a yield of 71.0%.

Embodiment 3

[0053] Example 3: Synthesis of Metal Organic Frameworks

[0054] Dissolve 192g of copper nitrate trihydrate in 400mL of water, dissolve 100g of pyromellitic acid in 800mL of DMF, mix the obtained aqueous solution of copper nitrate trihydrate and aqueous solution of pyromellitic acid, let it stand for a reaction at 60°C for 3 days, and then cool the resulting reaction product Return to room temperature and perform suction filtration. During the suction filtration, 50 ml of ethanol was used to wash three times. The resulting filter cake was dried at 60° C. for 24 hours to obtain 89.4 g of the product, with a yield of 54.2%.

Abstract

The invention relates to the technical field of materials, in particular to a metal organic framework material, a synthetic method and an application thereof. The X-ray diffraction peak positions of power of the framework material are as follows: 7.95+ / -0.5, 11.43+ / -0.5, 15.80+ / -0.5, 16.77+ / -0.5 and 18.89+ / -0.5; the 2theta angle range is between 5 degrees to 60 degrees. The material has the beneficial effects that the invention provides a novel metal organic framework material which has relatively high porosity, excellent water stability and heat stability and has a wide application prospect in the fields of photo-catalysis, hydrogen storage and ultraviolet resistance. Meanwhile, the synthetic material is low in price and easily available in raw material. The synthetic method is simple andlow in cost, can carry out amplified production on the premise of not affecting the product performance, and is suitable for industrial production and application.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a metal organic framework material, its synthesis method and application. Background technique [0002] Metal-organic framework materials (Metal-Organic Framewoks, MOFs) are organic-inorganic coordination polymers that have developed rapidly in recent years. The surface area has a wide range of applications in the fields of gas adsorption, gas separation, catalysis, and sensing elements. [0003] In the prior art, there are few types of metal-organic framework materials, and the yield of related synthesis methods is not high, it is difficult to scale up to industrial applications, and there is no practical application prospect. Contents of the invention [0004] The technical problem to be solved by the present invention is that there are few kinds of existing metal-organic framework materials, and the output of related synthesis methods is not high, it is difficult to scale...
