MANUFACTURING METHOD OF CHROMIUM-BASED METAL ORGANIC FRAMEWORKS

摘要

The present invention relates to a manufacturing method of a chromium-based metal organic framework, which comprises the steps of: pulverizing chromium salt and obtaining pulverized chromium salt; mixing the pulverized chromium salt with an organic ligand and obtaining a chromium salt-organic ligand mixture; and pulverizing the chromium salt-organic ligand mixture and obtaining a pulverized chromium salt-organic ligand product. In the present invention, a chromium-based metal organic framework having high specific surface area greater than or equal to 4,100 m^2/g and a yield rate greater than or equal to 90% can be obtained through a two-step pulverizing dry-gel conversion method, while significantly shortening a complicated refining process.
