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.
