Abstract

The invention provides a metal organic framework material containing dipyridyl carboxylic acid and a synthesizing method of the metal organic framework material, and belongs to the field of organic framework material electro-catalysis materials. The electro-catalysis material has the structural formula shown in the description, wherein L represents the element shown in the description, L1 represents coordinated water, and n represents multiple replication. The amount-of-substance mole ratio of 2,2-bipyridine-3,3-dicarboxylate to adipic acid to neodymium chloride is 2:(2-3):(1-3), 2,2-bipyridine-3,3-dicarboxylate, adipic acid and neodymium chloride are mixed and dissolved with water, stirring is carried out, the pH is regulated to be 4, the mixture is put into a sealed container for a constant temperature reaction at 145 DEG C for 96 h, the temperature is reduced to the room temperature at 1-2 DEG C / h, and purple transparent tabular crystals are obtained. The metal organic framework material containing dipyridyl carboxylic acid and the synthesizing method of the metal organic framework material are simple in synthesizing step, a complex has the ORR activity, and the metal organic framework material can serve as metal organic framework material electro-catalysis materials and has good application prospects.

Description

technical field [0001] The invention relates to a metal-organic framework material formed of 2,2'-bipyridine-3,3'dicarboxylic acid, adipic acid and metal neodymium, a preparation method thereof, and the application of the electrocatalytic properties of the material. Background technique [0002] MOFs (Metal-Organic Frameworks) materials are ordered network structures formed by bridging metal or metal cluster central ions and organic ligands. The Chinese name is metal-organic framework materials, also known as metal coordination polymers, because The designability and adjustability of its structure, easy functionalization and other characteristics have developed rapidly in the fields of energy storage, gas adsorption, optical, electrical, magnetic materials, catalysis, and drug carriers, and have broad application prospects. Among the ligands containing nitrogen and oxygen, pyridinecarboxylic acid ligands have nitrogen-containing heterocyclic rings and carboxylic acid groups,...
