Embodiment 1

[0020] 3,5-pyridinedicarboxylic acid (3,5-PDA) (0.084 g, 0.5 mmol), CuCl 2 2H 2 O (0.085 g, 0.50 mmol), PbCl 2 (0.024, 0.16 mmol) and 5 mL DMF were mixed into a vial, sealed, and placed in an oven. Constant temperature at 80°C for 72 h, and then after 1.4 ° Cool down to 40 °C at C / h to obtain blue blocky crystals. The calculated yield was 40% based on metallic Cu.

Abstract

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.

Description

technical field [0001] The invention relates to the preparation technology of polymer materials, in particular to a porous copper coordination polymer material and its preparation method and application. Background technique [0002] The synthesis and properties of porous coordination polymers are one of the important research fields in inorganic chemistry and materials chemistry developed in the late 1990s. Due to the low density of coordination polymers with an open pore structure, which is only one-third of that of traditional metal hydrides, the use of porous coordination polymers as hydrogen storage media can greatly reduce the weight of hydrogen storage devices. This feature is especially in line with the hydrogen supply system requirements of hydrogen fuel cell vehicles. In addition, this type of material also has the characteristics of large specific surface area and large pore volume, so it is a new type of high-capacity lightweight hydrogen storage material, and h...
