Abstract

The invention discloses a one-dimensional structure metal-organic framework compound and a preparation method thereof. The preparation method comprises the steps that 1, a supersaturated quantity of organic ligands are taken to be added into solvent, and heating is performed until the organic ligands are completely dissolved to prepare a supersaturated solution; 2, metal salt is added into the supersaturated solution for reacting, separating and drying are performed after full reacting is finished, and then the one-dimensional structure metal-organic framework compound is prepared. The prepared one-dimensional structure metal-organic framework compound is of a one-dimensional nanometer linear structure, the length is 100 nanometers-100 micrometers, and the diameter is 20 nanometers-10 micrometers. The one-dimensional structure metal-organic framework compound has the better mechanical property, the higher strength and the better toughness and has the special electrical property of a nanowire. The preparation method of the one-dimensional structure metal-organic framework compound is easy to operate, mild in condition, short in reaction time and suitable for scale production.

Description

technical field [0001] The invention belongs to the technical field of nanocomposite materials, and in particular relates to a one-dimensional structure metal organic framework compound and a preparation method thereof. Background technique [0002] Metal-organic frameworks (MOFs) are a new class of functional materials with a network topology. It is a type of composite material formed by the combination of metal ions and organic ligands through coordination bonds. The metal ions are located at the apex of the structure. The ligands are linked into a network. This special combination method makes the MOFs structure have a large number of micropores (less than 2nm), and the specific surface area of ​​some MOFs structures usually reaches 3000m 2 / g, it has great application value in gas adsorption, gas separation, catalyst, sensor, and drug carrier. [0003] The main synthesis methods of metal organic framework compounds are: hydrothermal method, solvothermal method, microwa...
