Title:
METAL ORGANIC FRAMEWORK DERIVED CARBON MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/065375
Kind Code:
A1
Abstract:
A metal organic framework (MOF) derived carbon material, a preparation method therefor and an application thereof, relating to the technical field of radioactive gas adsorption and removal. The MOF derived carbon material is obtained by heating and carbonizing a zeolite imidazole framework precursor in an inert gas environment. The MOF derived carbon material inherits the inherent network connection of a precursor MOFs material, and compared with traditional activated carbon materials, the MOF derived carbon material has the characteristic that the pore structure is adjustable, greatly improving adsorption selectivity of radioactive gas radon. Meanwhile, high-temperature carbonization is carried out by means of a proper path, thereby increasing the effective pore volume of the material, increasing the adsorption capacity of the material to radon, and also improving adsorption efficiency of the material.
