Metal-organic frameworks (MOFs) are a class of crystalline materials with a structure of inorganic nodes connected by organic ligands. There are currently more than 60,000 known MOFs, and they are being investigated as promising materials for gas storage, including CO2 sequestration and hydrogen storage, and can even be used to harvest water in the desert. Research so far has concentrated on MOFs in the solid state, but these soft, microcrystalline powders are hard to process industrially, as they can’t be sintered and are hard to form into pellets.
