THE IMPROVED PREPARATION METHOD OF POROUS METAL ORGANIC FRAMEWORK

摘要

PURPOSE: A porous metal-organic framework, a manufacturing method thereof, and an adsorbent or a preservative of micromolecules using the same are provided to have large pores due to a long organic linking group, to be able to react the metal-organic framework with various materials using the functional groups existing in the organic linking group, and to be able to improve a higher specific surface area and yield. CONSTITUTION: A manufacturing method of a porous metal-organic framework comprises the following steps: a step of forming a metal-organic framework by dissolving metal salt in which a metal ion of 1-16 group and an anion of 14-17 group are combined, and organic ligand precursor in a mixing solvent of an organic solvent and water; a step of exchanging solvent to dip the metal-organic framework in a first solvent; a step of processing a continuous mixing supercritical treatment to the washed metal-organic framework using supercritical carbon dioxide and a second solvent; and a step of drying the metal-organic framework processed with continuous mixing supercritical treated at high temperature and reduced pressure.
