Embodiment 1

[0038] 0.4g H 6 TTHA, 0.64g 4,4′-bipyridine and 0.8g Co(NO 3 ) 2 ·6H 2 O was added to 25 mL of deionized water. Then place it in an autoclave at 100° C. for 48 hours at a constant temperature. After cooling down to room temperature, crystals are precipitated, and the crystals are washed with deionized water for several times to obtain a cobalt complex. The cobalt complex is a pink blocky crystal. Elemental analysis data C 80 h 110 N 22 o 44 co 3 , Theoretical: C, 42.5; H, 4.9; N, 13.63%. Found: C, 42.9; H, 4.54; N, 13.25%. Main infrared data (KBr, cm -1 ): 3259(s); 2940(w); 1704(s); 1605(m); 1549(m); 1482(s); 1318(s).

[0039] Analyze the single crystal structure of the cobalt complex prepared in Example 1 of the present invention, collect the single crystal diffraction data with a Bruker Smart CCD diffractometer, and use a graphite monochromator to monochromatize Mo / kα rays Scan, obtain following result: the cobalt complex that the embodiment of the present in...

Embodiment 2

[0041] 0.4g H 6 TTHA, 0.64g 4,4′-bipyridine and 0.8g Co(NO 3 ) 2 ·6H 2 O was added to 25 mL of deionized water. Then place it in an autoclave at 140° C. for 72 hours at a constant temperature. After cooling to room temperature, crystals precipitate out. The crystals are washed with deionized water several times to obtain a cobalt complex. The cobalt complex is a pink blocky crystal.

[0042] The cobalt complex prepared in Example 2 of the present invention was analyzed by X-ray diffraction, and its diffraction peaks were consistent with the simulated diffraction peaks obtained by single crystal analysis in Example 1 of the invention, such as image 3 As shown, it is illustrated that the same substance is obtained according to the preparation methods of Example 1 and Example 2.

Abstract

The invention discloses applications of a cobalt complex as a greenhouse gas adsorption material. The molecular formula of the cobalt complex is {[Co<3>(H<3>TTHA)<2>(4, 4'-bipy)<5>(H<2>O)<8>*12H<2>O]}<n>, wherein H<3>TTHA is used for representing ligand 1, 3, 5-triazine-2, 4, 6-triamine-hexaacetate (H6TTHA) lost three protons, and 4, 4'-bipy is used for representing 4, 4'-dipyridyl molecules. Thecobalt complex possesses excellent adsorption performance on water vapour and CO2, the structure can be maintained to be stable at high humidity environment, recycling can be realized, and the cobaltcomplex is an excellent greenhouse gas adsorption material.

Description

technical field [0001] The invention relates to a gas adsorption material, in particular to a metal ion with cobalt (II) as the center, 4,4'-bipyridine and H 3 TTHA 3- Cobalt carboxylate (cobalt-carboxylic acid complex) composed of ligands is used as a greenhouse gas adsorption material and belongs to the technical field of environmental adsorption materials. Background technique [0002] In recent years, the greenhouse effect has become a hot issue of global concern, and many countries, institutions and organizations are committed to controlling human activities to prevent further deterioration of the environment. The critical value of greenhouse gases in the environment will have serious consequences, such as global warming, melting glaciers, and human discomfort or even death due to environmental pollution. Greenhouse gases mainly include H 2 O and CO 2 At present, in addition to restricting human industrial activities, the most important thing is to develop adsorptio...
