Metal halide perovskite quantum dots, with high light-absorption coefficients and tunable electronic properties, have been widely studied as optoelectronic materials, but their applications in photocatalysis are hindered by insufficient stability because of the oxidation agglomeration under light, heat, atmospheric conditions. To address this challenge, herein, we encapsulated CsPbBr3 nanocrystals into a stable iron-based metal–organic framework (MOF) mesoporous cages (∼5.5 4.2 nm) via sequential deposition route to obtain perovskite-MOF composite material, CsPbBr3@PCN-333(Fe), which were stabilized from aggregation or leaching confinement effect MOF cages. The monodispersed (4–5 within lattice directly observed transmission electron microscopy corresponding mapping analysis further confirmed powder X-ray diffraction, infrared spectroscopy, N2 adsorption characterizations. Density functional theory calculations suggested significant interfacial charge transfer dots PCN-333(Fe), is ideal for photocatalysis.
