Preparation method of metal organic polymer material

Abstract

The invention discloses a preparation method of a metal organic polymer material. The preparation method comprises the following steps: in an electrolytic cell, using ionic liquid as electrolyte, using a metal electrode or a titanium-based oxide electrode as an anode, using a titanium plate as a cathode, turning on a power supply, controlling the temperature and current density to carry out electric synthesis, carrying out solid-liquid separation, washing the product through a solvent, and then, washing the product through chloroform, and drying the product to obtain the metal organic polymer material; and finally, removing organic ligands, metal salt ions and solvent molecules out of pores of the synthesized metal organic polymer material and from surfaces of the pores to prepare the metal organic polymer material. The method of the invention is carried out under normal temperature and normal pressure, thereby having the advantages of mild reaction conditions, simple process, easiness for controlling the reaction, no secondary pollution, etc and is clean, sanitary and friendly to the environment.

Description

technical field [0001] The invention relates to a method for preparing a metal organic polymer material, in particular to a method for preparing a metal organic polymer material by an electrochemical method in an ionic liquid. Background technique [0002] Metal-organic polymer materials are one of the important functional materials in the high-tech field, and are widely used in gas separation, hydrogen storage, catalysis and other fields. At present, it is mainly synthesized by hydrothermal / solvothermal method with high temperature, high pressure and high energy consumption. Professor Wu Zhensen from Xidian University synthesized two-dimensional coordination polymer [Pb(ima) by sol-gel diffusion 2 ] n single crystal, and the internal structure of the crystal was measured by single crystal XRD. This method is easy to obtain high-quality single crystals, but this method is time-consuming, usually the reaction lasts for dozens of days, and the reaction conditions are relati...
