Embodiment 1

[0031] Take 0.35mol / l AgNO 3 An equal volume of the aqueous solution was impregnated on 9.10g sorbitol, and after impregnating for 3 hours, it was dried at 100°C for 6 hours. Sorbitol loaded with silver ions and 2.41g Cu(NO 3 ) 2 ·3H 2 O. 6.48g of 2,6-naphthalene dicarboxylic acid was mixed thoroughly and stirred evenly; then 1.5g of hydrofluoric acid was added dropwise to the above mixture, and stirring was continued for 30min. Then transfer the mixture to the reactor, seal it, raise the temperature from room temperature to 100°C at 5°C / min, and treat it at a constant temperature for 2 hours; then raise the temperature to 200°C at a rate of 3°C / min, and treat it at a constant temperature for 5 hours; continue to heat up and keep at 3°C / min. The temperature was raised to 350°C and kept constant for 10 hours; then it was lowered to room temperature, and the cooling rate was maintained at 2°C / min. After the sample was cooled to room temperature, light green crystals were obt...

Embodiment 2

[0034] In embodiment 1, take 0.35mol / l AgNO 3 An equal volume of the aqueous solution was impregnated on 14.29 g of sorbitol, and other operating methods and material compositions remained unchanged to obtain a metal-organic framework material B containing Cu and Ag, which was determined to be the metal-organic framework material of the present invention by the analytical test method of Example 1 , where the molar ratio of Cu atoms to Ag atoms is 1:0.5.

Embodiment 3

[0036] In Example 2, the addition of 2,6-naphthalene dicarboxylic acid was increased to 21.60 g, and other operating methods and material compositions remained unchanged to obtain a metal-organic framework material C containing Cu and Ag. According to the analysis of Example 1 The test method is determined to be the metal organic framework material of the present invention, wherein the molar ratio of Cu atoms to Ag atoms is 1:0.3.

Abstract

A metal organic framework material and a preparing method thereof are disclosed. The metal organic framework material is formed by bridging a CuO4(OH)3Ag octahedron and naphthalenedicarboxylic acid in space, and has a chemical formula of Cu(OH)Ag(C10H6O4). A preparing process of the framework material includes: dipping polyol solid particles to a silver salt solution, drying, mixing with a copper salt and the naphthalenedicarboxylic acid, adding dropwise hydrofluoric acid, sealing and reacting, performing a specific constant-temperature processing, cooling, filtering, washing with water, drying and calcinating to obtain the metal organic framework material. The metal organic framework material has a specific pore structure, is particularly suitable for a natural gas storage process, and is characterized by improving capability of selective adsorption of methane and being large in storage amount and long in using period.

Description

technical field [0001] The invention relates to a metal-organic framework material and a preparation method thereof, more specifically to a novel metal-organic framework material for methane adsorption and a preparation method thereof. Background technique [0002] Natural gas, the main component of which is methane, is a clean, environmentally friendly, economical and affordable fossil energy. Natural gas reserves are abundant in the world. As far as China is concerned, according to the "China Energy Development Report (2010)" data, China's recoverable natural gas resources are 22 trillion cubic meters. In the next 10 years, China will accelerate into the era of natural gas energy, and the proportion of natural gas in China's energy consumption structure will also increase significantly. However, the storage density and energy density of natural gas are relatively low, which directly affects the recovery, storage, transportation and comprehensive utilization of natural gas...
