Document Type and Number:
WIPO Patent Application WO/2024/019398
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a metal-organic framework, the method enabling storage capacity of a functional material such as acetylene to be increased. The present invention relates to a method for preparing a metal-organic framework comprising coordination products of metal ions and organic ligands, the method comprising the steps of: (a) reacting a metal precursor and an organic ligand in a first solvent, thereby generating an intermediate; and (b) immersing the intermediate in a second solvent for a predetermined time, thereby removing impurities while simultaneously generating a crystallized metal-organic framework from the intermediate.
