Selective Photocatalytic C─H Oxidation Using All‐Inorganic Perovskite Quantum Dots Encapsulated in UiO‐Series MOFs

Abstract All‐inorganic cesium lead halide (CsPbX 3 , X = Cl, Br, I) perovskite quantum dots (PeQDs) are successfully incorporated within the cages of zirconium‐based UiO‐series metal–organic frameworks (MOFs) using in situ ship‐in‐a‐bottle method at room temperature under ambient conditions. The resulting mBPP‐MOF, which includes the 4,4′‐(2,2′‐bipyridyl‐5,5′‐diyl)dibenzoic acid (H 2 BPP) linker, features a larger cavity size than UiO‐66 and UiO‐67‐bpy, allowing for uniform accommodation of PeQDs within its cages. This PeQDs@MOF hybrid heterostructure enhances the separation and transfer of photogenerated charges, enabling the synthesized CsPbBr 3 @mBPP‐MOF to demonstrate highly selective and stable performance in the photocatalytic oxidation of toluene under visible light irradiation at 395 nm. This advancement represents a potential breakthrough in organic photocatalysis due to the material's low cost, ease of processing, high efficiency, and tunable bandgap.
