Abstract

The invention discloses a preparation of a hydrophobic double MOF-based porous carbon material. The method comprises the following steps: after uniformly mixing the MOF-5 material and another iron-based MOF material according to a certain ratio, carbonizing it at high temperature, namely The hydrophobic porous carbon material is obtained. The preparation process of the method of the present invention is simple, and the product has a large specific surface area and abundant pores. At the same time, the degree of graphitization of the porous carbon material is improved by the iron-catalyzed graphite method, thereby improving its hydrophobicity. It has a good application prospect in adsorption separation.

Description

technical field [0001] The invention belongs to the field of preparation of porous carbon materials, and in particular relates to the preparation of a hydrophobic double MOF-based porous carbon material. Background technique [0002] Metal Organic Frameworks (MOFs for short) are zeolite-like materials with a periodic network structure formed by self-assembly of organic ligands and metal ions through coordination and covalent bonds. Compared with traditional adsorption materials, this new material has high porosity and huge specific surface area (up to 7000m 2 / g), controllable pore structure design, and surface modification, it has great application prospects and development potential in gas storage, adsorption separation, and catalysis. However, since MOFs are crystals with a three-dimensional network structure formed by hybridization of coordination bonds with inorganic metal centers, the stability of MOFs materials is relatively poor compared with other porous materials....
