Title:
METAL-ORGANIC FRAMEWORK MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/233065
Kind Code:
A1
Abstract:
The present invention pertains to the field of inorganic materials, and in particular relates to a metal-organic framework material. The present invention provides a metal-organic framework material, comprising a plurality of linked M-O-L secondary structural units, wherein M is selected from metals, O is an oxygen atom of a carboxylate radical-based linking cluster, L is an organic linking ligand, and the organic linking ligand includes a flexible triangular ligand and two or more linear ligands with different lengths. The metal-organic framework material provided by the present invention has an ultra-high specific surface area, an appropriate pore shape/size, and a properly functionalized inner pore surface chemical environment, and has an ultra-high storage capacity for gas molecules, especially methane gas, and is applicable to high-density and small-volume effective storage of on-board natural gas of a natural gas vehicle, greatly increasing the cruising range of the vehicle.
