Rapid Production of Metal−Organic Frameworks via Microwave-Assisted Solvothermal Synthesis

Abstract

This paper describes a very rapid technique for the production of metal-organic frameworks (MOF). The method uses a conventional microwave to nucleate crystal growth. A MOF synthesis that used to take hours or days can now be completed in 30 s to 2 min. The yield goes from approximately 30% to over 90%. Novel MOFs can be made, since the growth process is no longer dependent on the walls or dust particles for nucleation. Particle sizes have a narrower distribution. Further, the particle size can be controlled by varying the precursor concentration.
