Porous copper coordination polymer material as well as preparation method and application thereof

The invention relates to a porous copper coordination polymer material which is characterized in that a copper coordination polymer in a three-dimensional nanometer pore structure is synthesized by selecting 3,5-cinchomeronic acid (3,5-Pyridinedicarboxyli cacid) as a ligand; a chemical formula of the copper coordination polymer is expressed as [Cu3(3,5-PDA)2.5Cl(DMF)2] Solvent, wherein 3,5-PDA is 3,5-cinchomeronic acid, and DMF is N,N-dimethylformamide. The porous copper coordination polymer material is prepared through the following steps of: (1) placing a mixture of CuCl2.2H2O, PbCl2, 3,5-PDA and DMF into a hydro-thermal reaction kettle for reaction; (2) reducing temperature to 40 DEG C, thermally filtering, and washing with the DMF so as to obtain a target product. The porous copper coordination polymer is applied to a hydrogen storage material. The invention has simple process, high yield and very high thermal stability of products and is more superior compared with the traditional hydrogen storage material.
