Problems solved by technology

Due to the disordered distribution of carboxyl groups in the polymer macroporous microspheres functionalized with carboxyl groups and the high arrangement density of carboxyl groups, Co 2+ When coordinating with the carboxyl group, it is easy to undergo excessive coordination complexation, that is, changing the ZIF (Co 2+ )-type metal-organic framework materials should have a spatial coordination structure, resulting in a decrease in adsorption capacity
At the same time, this method cannot guarantee that Co 2+ Effectively go deep into the internal coordination of carboxyl-functionalized polymer macroporous microspheres, so the coordination mainly occurs on the outer surface of carboxyl-functionalized polymer macroporous microspheres, that is, the physical and chemical properties are not high

Abstract

The invention relates to a hybrid material containing a metal organic framework material, and a preparation method thereof. The preparation method comprises: (1) carrying out acid treatment on an aluminosilicate carrier, washing to achieve a neutral state, and drying; (2) immersing the carrier in an organic ligand solution, and impregnating; (3) transferring the material into a reactor containinga copper salt solution while supplying a trimesic acid solution, and carrying out stand treatment at a low temperature; and (4) transferring the reactor into a drying oven, drying, taking the mixtureout of the reactor, filtering, washing, and drying to obtain the hybrid material containing the metal organic framework material. According to the present invention, the copper-based metal organic framework material HKUST-1 in the hybrid material grows uniformly, and the hybrid material has high ethylene adsorption capacity and selective ethylene / ethane adsorption separation effect, and further has good mechanical strength.

Description

technical field [0001] The invention belongs to the field of organic materials, in particular to a hybrid material containing a metal-organic framework material and a preparation method thereof. Background technique [0002] The copper-based metal-organic framework material HKUST-1, also known as Cu-BTC, was synthesized by the Williams team of Hong Kong University of Science and Technology in 1999. This electrically neutral material consists of web-shaped Cu 2 (COO) 4 It is composed of structural units, and the structural units are connected to each other to form a three-dimensional three-dimensional channel structure with a face-centered cubic space lattice type. When the copper ion-bound water is removed from the framework, HKUST-1 will have unsaturated metal coordination sites, and the main pore size of this structure is 0.9 nm. Since HKUST-1 possesses two typical cavities, it is an excellent material for the adsorption and separation of gas molecules. In addition, th...
