“…Cyclic carbonates (CCs) are high value-added chemicals that have numerous applications in polymerization reactions, lithium-ion batteries, and the preparation of cosmetics and pharmaceuticals. − In this context, direct conversion of alkenes and CO 2 to CCs has attracted great interest owing to its high atom economy and the reduction in the levels of greenhouse gases. Typically, one-pot synthesis of a CC from styrene and CO 2 involves a two-step process, involving a selective oxidation reaction of styrene to form the corresponding epoxide and then subsequent cycloaddition of the epoxide with CO 2 to generate the CCs.…”

Catalysis has played a decisive role in the development of unique chemical reactions to produce important chemicals. However, conventional stepwise synthetic routes that rely on individual catalysts to promote each step often suffer from ponderous processes for the isolation of intermediates that result in massive material losses and large economic expenditures. In addition, traditional powder forms of these catalysts suffer from poor processability and recoverability. Herein, we designed and prepared a hierarchical metal−organic framework (MOF) composite monolithic catalyst IL-Au@UiO-66-NH 2 /CMC that contains integrated acid (Zr 4+ ), base (ionic liquid (IL)), and metal sites (Au nanoparticles (NPs)) to promote the one-pot preparation of cyclic carbonates from styrene derivatives and CO 2 . Highly dispersed Au NPs, IL 1-aminoethyl-3-methylimidazolium bromide ([C 2 NH 2 MIM] [Br]), and MOF-positioned Lewis acid sites within this composite aerogel are separately responsible for catalyzing selective epoxidation of the styrene derivatives and the subsequent cycloaddition reaction of CO 2 with intermediate styrene oxides. Importantly, inclusion of the imidazolium-based IL effectively modulates the size and chemical microenvironment of the Au NPs via electrostatic protection, leading to catalyst stability and its selective oxidation of styrene. Benefiting from the rapid mass transfer and high exposure of active sites within the pore-rich hierarchical nanostructure, IL-Au@UiO-66-NH 2 /CMC promotes high conversion (90.5%) of the styrene and selectivity (80.5%) for styrene carbonate (SC) formation in the one-pot process, a performance level that far exceeds those of related catalysts containing only Au NPs or IL (the selectivity of SC < 42%). Furthermore, the composite aerogel catalyst can be readily separated and recycled at least five times without a remarkable loss of activity and selectivity. The controllable integration of various active components in the hierarchical MOF composite aerogel herein should serve as the foundation for the design of multifunctional monolithic catalysts for other valuable tandem processes.

“…As an emerging class of porous adsorbent, metal–organic frameworks (MOFs) composed of metal clusters/ions interconnected by organic ligands have the advantages of large specific surface area, adjustable pore size, and easy functionalization, − which make them widely used in many fields such as gas separation and storage, , catalysis, , etc. − MOFs can precisely distinguish similar materials with only slight diversities because of their powerful reticular chemistry, which is often difficult for traditional adsorbents to achieve. Therefore, it has considerable advantages in separating gas mixtures with similar structural similarities and small molecular size differences.…”

Separation of the ethane/ethylene mixture is one of the most important but challenging processes in the petrochemical industry owing to their closely resembling physical and chemical characteristics. The remarkable characteristics of customized pore aperture and functionality endow metal−organic frameworks (MOFs) with great prospects in the adsorption separation of an ethane/ethylene mixture. However, large fixed-bed pressure drops, dustiness, transportation, and handling challenges of the powdered MOFs have largely restricted their large-scale industrial applications. Herein, we successfully prepared a silver-functionalized MOF pellet adsorbent using renewable carboxymethyl cellulose (CMC) as the binder and explored its feasibility for adsorptive separation of C 2 H 4 /C 2 H 6 in the industry via both single-component adsorption isotherms and breakthrough experiments. Scanning electron microscopy and N 2 adsorption isotherms revealed the "solid bridge" formed by CMC between MIL-101-SO 3 Ag@CMC pellets that tightly hold MOF crystals together while minimizing pore blockage. In addition, the pellets also attained excellent mechanical strength and stability sufficient to meet industrial application standards. Due to the formation of πcomplexation between Ag(I) ions and the ethylene, MIL-101-SO 3 Ag@CMC pellets demonstrated a moderate-high ethylene adsorption capacity of 2.23 mmol/g at 298 K and 1 bar and an excellent separation performance for ethylene/ethane. Significantly, the ideal adsorbed solution theory selectivity of the ethylene/ethane (50:50, v/v) mixture for pellets was 25.2 at 298 K and 10 kPa, far exceeding most reported adsorbents. Furthermore, breakthrough experiments and humid adsorption experiments verified that MIL-101-SO 3 Ag@CMC can achieve high-purity ethylene (>99.9%) from the binary ethane/ethylene (50:50, v/v) mixture, indicating that MIL-101-SO 3 Ag@CMC is a promising adsorbent with both efficient C 2 H 4 /C 2 H 6 selectivity and excellent stability.

“…In comparison to traditional materials, metal–organic frameworks (MOFs, Table S2 for abbreviations) possess many unique properties [ 7 , 8 ]. Their large pore volume, high porosity, and high surface area not only facilitate the higher loading of fragrances or guest molecules but also offer advantages such as high biocompatibility, good biodegradability, ease of functionalization, and higher water solubility.…”

To facilitate the integration of a fragrance encapsulation system into different products to achieve effective releases, a dual-responsive release system with pH and thermal trigger control is designed in this work. A series of ZIF-8 (M) and bilayer ZIF-8-on-ZIF-8 (MM) materials are synthesized by a solvent method at room temperature. The fragrance is encapsulated into the ZIFs by dynamic adsorption or in situ encapsulation combined dynamic adsorption. The fragrance loading contributed by dynamic adsorption was as high as 80%. The fragrance loaded in the double-layer MM host was almost twice that of the monolayer host M due to the stronger electrostatic interaction between MM and vanillin. In the pH and thermal trigger response release experiments, the second MOF layer in the MM host, as a controlled entity, greatly improved the load and kinetic equilibrium time of vanillin, and realized the controlled release of guest molecules. The developed dual-responsive release system in this work exhibits great potential in daily chemical products.
