Abstract: The present invention provides a metal-organic framework material for the adsorptive separation of acetylene/ethylene mixture and preparation method therefor. The metal-organic framework material is named TJE-2 with a chemical formula of [Ni(pyc)(apyz)]n, wherein, Ni represents nickel as a metal center, pyc represents the organic ligand 1H-pyrazole-4-carboxylic acid, and apyz represents the organic ligand 2-aminopyrazine. The preparation method is as follows: thoroughly dissolving pyc, apyz and Ni(NO3)2·6H2O, transferring the mixture to a pressure-resistant closed container for heating reaction, followed by solvent exchange and activation to obtain a homogeneous powder material. The ultra-microporous metal-organic framework material prepared by the present invention features a significantly high C2H2 adsorption capacity, good selectivity, and low raw material costs, and therefore can realize C2H2/C2H4 separation at lower costs.
