Abstract: Provided herein are methods of making the present metal-organic framework spheres and novel compositions produced by the same. In the present methods, sodium alginate and water are mixed to produce an aqueous sodium alginate solution. Metal-organic frameworks are added to the aqueous sodium alginate solution to produce an aqueous metal-organic framework alginate mixture. A calcium chloride solution is added to the metal-organic framework alginate mixture is added to form the metal-organic framework sphere. The metal-organic framework sphere produced has about 70 wt.% of metal-organic frameworks or less and a network of calcium alginate complexes and can withstand a crush strength of at least 44.5 N.

Abstract: Provided herein are methods of novel methods of synthesizing a metal-organic framework system by vapor-phase appending of a plurality of ligands appended to a metal-organic framework. Also, provided are methods of recycling metal-organic framework systems by detaching the ligand and re-appending the same ligand or appending a different ligand to the metal-organic framework to provide a recycled or repurposed metal-organic framework system.

Abstract: Provided herein are methods of making metal-organic frameworks comprising forming a suspension capable of producing metal-organic frameworks; inducing flocculation of the suspension to form a plurality of flocs; allowing the flocs to separate from the suspension and produce a solid phase comprising metal-organic frameworks and a supernatant liquid phase; separating the solid phase from the supernatant liquid phase; and recovering the metal-organic frameworks from the solid phase. The present methods include dissolving a metal salt and at least one ligand in a solvent to form the suspension.
