Solvent-supported compaction of metal-organic frameworks
Abstract:
Methods of forming a high surface area compacted MOF powder are disclosed, as well as MOF pellets formed thereby. The method may include synthesizing a metal organic framework (MOF) powder using a first solvent, exchanging the first solvent with a second solvent such that pores of the MOF powder are at least 10% filled with the second solvent, compacting the MOF powder having pores at least 10% filled with the second solvent into a pellet, and desolvating the compacted pellet to remove the second solvent. The pellet may maintain a specific surface area after compacting that is at least 80% its initial specific surface area. Compacting the MOF powder with a solvent at least partially filling its pores may prevent or reduce crushing of the MOF pore structure and maintain surface area, for example, for hydrogen or natural gas storage.
