Embodiment 1

[0036] In this example, a composite material of MOF, porous metal titanium, and Ni-Co-Mn ternary alloy is prepared by chemical compounding. The specific preparation method is as follows:

[0037](1) Activate the porous metal titanium and the Ni-Co-Mn ternary alloy, wherein the porous titanium is treated with 0.1mol / L hydrofluoric acid for 15 minutes, and the Ni-Co-Mn ternary alloy is treated with 0.2mol / L hydrochloric acid Treat for 20 minutes to remove the oxide film on the surface and expose the metal.

[0038] (2) Preparation of MOF-Y: Accurately weigh H 5 L (0.018g, 0.04mmol) and Zn (NO 3 ) 2 6H2O (0.1mmol, 0.030g), dissolved in 2mL of N,N-dimethylformamide (DMF) and water mixed solvent (V(DMF):V(H2O)=3:1), stirred evenly, packaged in In a reaction kettle lined with polytetrafluoroethylene, heated to 105°C for 72 hours, then cooled to room temperature at a cooling rate of 5°C, washed with DMF solvent, and dried at room temperature to obtain colorless blocky crystals.

Abstract

The invention relates to a compounding method of porous MOFs (metal-organic frameworks). The method comprises the following steps: S1, a porous metal interface is activated; S2, MOF-Y is prepared; S3, porous metal Ti and a Ni-Co-Mn ternary alloy which are activated in the step S1 are chemically compounded with MOF-Y, and compounding is realized; S4, the composite is represented. The invention further provides an application of the material prepared with the compounding method of the porous MOFs in hydrogen adsorption. The compounding method and the application have the following advantages: a novel technology and a novel thought are provided for preparation of the MOFs, porous metal Ti and Ni-Co-Mn ternary alloy composite, the novel composite which has wide application prospect in hydrogen adsorption is obtained, a good boost function is realized for acceleration of further practical application of MOFs, and important material support is provided for a hydrogen storage technology, so that the method and the application have very important practical values.

Description

technical field [0001] The invention relates to the field of synthesis of inorganic composite materials, in particular to a composite method of porous metal and organic framework compound and its application in hydrogen adsorption. Background technique [0002] Hydrogen is an ideal green and clean energy, and hydrogen has a very high combustion calorific value. The heat generated by burning 1kg of hydrogen is equivalent to the heat generated by burning 2.4kg of methane or 3kg of gasoline. The high energy makes hydrogen one of the important fuels to propel spacecraft, fuel cells, etc. Hydrogen itself is non-toxic, and the combustion product is water, which is non-polluting and can be recycled. Hydrogen can be used in many forms, and can appear as gaseous, liquid or solid metal hydrides, which can meet the different requirements of storage, transportation and various application environments. Therefore, it can be said that hydrogen energy is the most ideal and perfect energy...
