Hierarchically porous metal-organic frameworks (H-MOFs) are regarded as promising candidates for the fabrication of Pickering emulsions because of the features of tunable porosity, high specific surface area and structure diversity. However, CO<sub>2</sub>-switchable Pickering emulsions formed by hierarchically porous zirconium-based MOFs have never been seen. In this work, a novel kind of the amine-functionalized hierarchically porous UiO-66-(OH)<sub>2</sub> (H-UiO-66-(OH)<sub>2</sub>) has been developed using a post-synthetic modification of H-UiO-66-(OH)<sub>2</sub> by (3-aminopropyl)trimethoxysilane (APTMS), 3-(2-aminoethylamino)pMaterials (Basel, Switzerland)CO<sub>2</sub>-Switchable Hierarchically Porous Zirconium-Based MOF-Stabilized Pickering Emulsions for Recyclable Efficient Interfacial Catalysis.PMC9960431No22003055Liu JXie YXu DPei XSong WWang ZfalseCO<sub>2</sub>-Switchable Hierarchically Porous Zirconium-Based MOF-Stabilized Pickering Emulsions for Recyclable Efficient Interfacial Catalysis.Stimuli-responsive Pickering emulsions are recently being progressively utilized as advanced catalyzed systems for green and sustainable chemical conversion.
