Metal-organic frameworks (MOFs) are potential materials for gas adsorption/separation, catalysis, and sensing due to their remarkable porous characteristics. To enable their widespread utilizations, the challenge of continuous MOF synthesis for scaled production is addressed. The study focuses on recent advancements in the continuous synthesis and morphology control of MOF crystals through spray synthesis involving the creation of MOF crystals within sprayed droplets of precursor solutions during solvent evaporation. Through varying conditions and two apparatuses, continuous synthesis of HKUST-1 MOF is achieved with good production efficiency. Additionally, the spray-synthesis method demonstrates to synthesize nanocomposites of HKUST-1 with other functional nanomaterials as well as to fabricate thin films of HKUST-1 and self-standing nanocomposite films incorporating carbon nanotubes.
