Environmentally Benign Strategies to the Controlled Crystallization of MOF Sorbents

Year: 2026
Type: article
Abstract: Metal–organic frameworks (MOFs) are a vital class of porous materials with ultrahigh surface areas and tunable pore structures, yet conventional synthesis relies on toxic high-boiling organic solvents, hindering large-scale production and violating green chemistry principles.This work explores green aqueous synthesis of MOF sorbents via controlled nucleation and crystal growth. Using zirconium fumarate (MOF-801) as the model, zirconyl chloride-derived samples show optimal crystallinity and water uptake, reaching 470–490 mg g⁻¹ at 96.5–97.5% relative humidity. For aluminum fumarate, a modified aqueous route with controlled ligand addition avoids organic solvents and fluorine-containing reagents entirely.The strategy is extended to MIL-101(Cr) and MOF-199 by tuning crystallization kinetics and separating nucleation/growth stages, yielding highly crystalline porous materials with excellent adsorption performance. These approaches support sustainable MOF production for water purification, atmospheric water harvesting and related applications.
