Title:
IMPERFECT MOFS (IMOFS) MATERIAL, PREPARATION AND USE IN CATALYSIS, SORPTION AND SEPARATION
Document Type and Number:
WIPO Patent Application WO/2017/210874
Kind Code:
A1
Abstract:
A creation of defects (defect structures) in Metal organic frameworks (MOFs) which generates imperfect MOFs (iMOFs) and the quantization of the defects in iMOFs are disclosed. The catalytic activity of iMOFs is also disclosed. In particular, the crystal growth-driven creation of defects (amount and type) in metal-organic frameworks which result in iMOFs are disclosed by using different synthesis procedures. The type of synthesis procedure, such as solvothermal, room temperature, microwave or spray drying, affects the crystal growth of metal-organic frameworks (MOFs), and specifically the structure, morphology and other properties of iMOFs such as crystal size, particle shape, surface area, defect structures (defects) and gas adsorption capacity and affinity toward N 2, CO 2, CH 4 etc. Moreover, high performance of MOFs in various catalytic reactions can be correlated to the higher amount of defect structures because defects can possibly display acid and/or basic properties. The amount of generated defects depends on the synthesis procedure of iMOFs. While studies of MOF crystallinity confirmed that for a given type of MOF different synthesis methods generated samples of similar crystal structures their morphologies were different due to the differences in the crystallization rates associated with these methods.
