Embodiment 1

[0017] Example 1. Rapid preparation of Cu at room temperature 3 BTC 2 , Mn 3 BTC 2 nanomaterials

[0018] Put Cu(OAc) 2 ·H 2 O (copper acetate monohydrate), Mn (OAc) 2 ·4H 2 O (manganese acetate tetrahydrate) was dissolved in 2 mL of water to make the concentration 0.18M. BTC (1,3,5-trimellitic acid) was dissolved in 2 mL of ethylene glycol to make the concentration 0.1M. At room temperature, 2mL copper acetate (0.18M) and 2mL manganese acetate (0.18M) aqueous solutions were added to two 2mL BTC solutions in ethylene glycol, and mixed and stirred for 5 minutes. The resulting precipitate was washed with ethanol and centrifuged, and the supernatant was discarded. Repeat the above operation at least three times, and finally disperse with ethanol. Then it was characterized by SEM (see figure 1 ), it can be seen that the size of the material obtained is nanometer.

[0019] Cu 3 BTC 2 And Mn 3 BTC 2 The yields of nanomaterials were 93.9% and 97.7% (calculated as BTC, containing solven...

Abstract

The invention discloses a method for rapidly synthesizing a BTC (1,3,5-benzenetricarboxylic acid)-based nanoscale organometallic framework material at room temperature. The nanomaterial is prepared by the following steps: mixing metal acetate aqueous solution with BTC solution at room temperature, and reacting to obtain BTC-based organometallic framework nanoparticles. The method is rapid, simple and energy-saving; the yield is high; the used raw materials and solvents are inexpensive and easily available; the safety problem of commonly used nitrate is not caused; the method is favorable to the industrial production and has wide application prospects in the fields of catalysis, adsorption, drug carriers, building of nano devices and the like.

Description

Technical field [0001] The invention relates to a synthetic nano-level metal organic framework material M 3 (BTC) 2 Methods. Background technique [0002] Metal-organic frameworks (MOFs) are a unique class of metal-organic frameworks (MOFs) formed by self-assembly of metal ions or clusters of metal ions and suitable multidentate bridging ligands with controllable size and morphology Inorganic and organic hybrid porous materials have attracted more and more attention. Because the special topological structure and pore size of MOFs can be designed and adjusted artificially, and the interaction with guest molecules can be affected by the functionalization of the pore surface, it is used in gas storage and separation, catalysis, sensing, imaging, and drug carriers. Shows huge application prospects. [0003] At present, most MOFs are synthesized by traditional solvothermal method, which not only consumes time and energy, but the synthesized MOFs particles are mostly micron-sized. Stu...
