Embodiment 1

[0030] A kind of microporous Cu-MOF material, its chemical formula is CuTIPA · n (DMF) (n=1-3), wherein TIPA 2- It is 5-(triazol-1-yl)isophthalic acid anion, DMF is N,N-dimethylformamide, TIPA 2- The simplified structure is as follows:

[0031]

Embodiment 2

[0033] A kind of preparation method of microporous Cu-MOF material as described in embodiment 1, comprises the following steps:

[0034] 11.6mg of H 2 TIPA was placed in a 20mL vial with a polytetrafluoroethylene lid, and 11.6mg of a mixed solvent was added to it, which was formed by mixing 1mL of water, 2mL of DMF, and 1mL of DMA, and then 50uL 1mol / L copper nitrate solution and added to the medium, sonicated until copper nitrate trihydrate and H 2 TIPA was mixed evenly, and then the above-mentioned vial was covered and placed in an oven at 85°C for three days to react to obtain blue rod-shaped crystals, which were microporous Cu-MOF materials.

Embodiment 3

[0036] The microporous Cu-MOF material as described in Example 2 is effective in the selective separation of CO 2 / N 2 and CO 2 / CH 4 in the application.

Abstract

The invention discloses a microporous Cu-MOF material, a preparation method and applications thereof, wherein the chemical formula of the microporous Cu-MOF material is CuTIPA.n(DMF) (n is 1-3), TIPA<2-> is 5-(triazole-1-yl)isophthalic acid anions, DMF is N,N-dimethylformamide, and the microporous Cu-MOF material has good water vapor stability and good organic solvent stability. According to the invention, gas adsorption test results show that the material has good selective adsorption performance on CO2, has good selective separation performance on CO2 / N2 and CO2 / CH4, and can be applied to the fields of capture and separation of CO2 in waste gas discharged by a power plant, purification of natural gas and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of metal-organic framework materials, in particular to a microporous Cu-MOF material and its preparation method and application. Background technique [0002] Since the industrial revolution, with the development of social industry, people have become more and more dependent on the combustion of fossil fuels such as coal, oil and natural gas to obtain energy, which has also led to the CO in the atmosphere 2 The sharp increase in the concentration of ions has caused a major impact on the climate and ecosystem, which will endanger the sustainable development of human society. According to statistics, currently 60% of the world's CO 2 Exhaust gas from power plants, the main component of the exhaust gas is CO 2 , N 2 and water vapor and other small amounts of impurity gases. So installing efficient, selective CO in coal or gas fired power plants 2 Capture device is very necessary, this move w...
