Encapsulating pre-formed nanoparticles in metal-organic frameworks (MOFs) expands their application potential in catalysis, filtration, and sensing. Current methods have limitations in the choice of core-nanoparticles, but a new synthesis strategy using seven MOF-shells and six NP-cores can incorporate from single to hundreds of cores in mono-, bi-, tri-, and quaternary composites without requiring specific surface structures or functionalities. Regulating the rate of alkaline vapors diffusion triggers controlled MOF-growth and encapsulation of NP-cores. This strategy paves the way for exploring sophisticated MOF-nanohybrids using known MOF-architectures and core-compositions.
