Layered metal-organic frameworks would be a diverse source of crystalline sheets with nanometer thickness for molecular sieving if they could exfoliated, but there is challenge in retaining the morphological and structural integrity. We report preparation 1-nanometer-thick large lateral area high crystallinity from layered MOFs. They are used as building blocks ultrathin sieve membranes, which achieve hydrogen gas (H2) permeance up to several thousand permeation units (GPUs) H2/CO2...
Molecular strainer: An ultramicroporous zeolitic imidazolate framework (ZIF-7) was tested for its gas-separation properties in membrane applications. ZIF-7 appended to an asymmetric alumina support using microwave-assisted seeded growth, and the resulting exhibits high H2 selectivity as a molecular sieve has excellent thermal stability.
Tailoring of the crystal size and morphology metal–organic framework (MOF) materials manipulation MOF films is possible by solvothermal synthesis route introduced here. A c-out-of-plane ZIF-7 membrane (see figure) obtained through evolutionary selection in a van der Drift–type growth originating from randomly oriented seed layers. Highly thin are important as molecular sieve membranes. Detailed facts importance to specialist readers published "Supporting Information". Such documents...
Abstract Fine‐tuning of effective pore size microporous materials is necessary to achieve precise molecular sieving properties. Herein, we demonstrate that room temperature ionic liquids can be used as cavity occupants for modification the microenvironment MOF nanocages. Targeting CO 2 capture applications, tailored cage ZIF‐8 between and N by confining an imidazolium‐based liquid [bmim][Tf N] into ZIF‐8’s SOD cages in‐situ ionothermal synthesis. Mixed matrix membranes derived from...
On the road to recovery: The dynamic apertures and superhydrophobic surfaces of metal–organic framework ZIF-8 result in its extraordinary ability selectively adsorb alcohols. When incorporated into a polymer matrix, nanoparticles provide preferential pathways for permeation organic compounds allow efficient pervaporative recovery bio-alcohols from fermentation broths (see picture).
Abstract Metal–organic framework (MOF) nanosheets could serve as ideal building blocks of molecular sieve membranes owing to their structural diversity and minimized mass‐transfer barrier. To date, discovery appropriate MOF facile fabrication high performance nanosheet‐based remain great challenges. A modified soft‐physical exfoliation method was used disintegrate a lamellar amphiprotic into with aspect ratio. Consequently sub‐10 nm‐thick ultrathin were successfully prepared, these...
The metal-organic framework ZIF-8, which undergoes hydrolysis under hydrothermal conditions, is endowed with high water-resistance after a shell-ligand-exchange-reaction. stabilized ZIF-8 retains its structural characteristics improved application performances in adsorption and membrane separation.
A new ZIF-8 membrane architecture with high performance supported on vertically aligned ZnO nanorods was successfully prepared. The aligned, single crystal were grown seamlessly from porous ceramic support to form an intermediate layer for the membrane. They provide multiple anchorages that are both strong and flexible. activated induce a uniform nucleation of ZIF nuclei their surface initiate guide growth defect-free Single gas permeations binary separations carried out investigate...
Abstract Two‐dimensional covalent organic frameworks (2D COFs) are considered as potential candidates for gas separation membranes, benefiting from permanent porosity, light‐weight skeletons, excellent stability and facilely‐tailored functionalities. However, their pore sizes generally larger than the kinetic diameters of common molecules. One great challenge is fabrication single‐phase COF membranes to realize precise separations. Herein, three kinds high‐quality β‐ketoenamine‐type...
With a series of merits, Prussian blue analogs (PBAs) have been considered as superior cathode materials for sodium-ion batteries (SIBs). Their commercialization, however, still suffers from inferior stability, considerable [Fe(CN)6 ] defects and interstitial water in the framework, which are related to rapid crystal growth. Herein, "water-in-salt" nanoreactor is proposed synthesize highly crystallized PBAs with decreased water, show both specific capacity rate capability SIBs. The...

A pioneering achievement is made in developing integrated Janus hydrogel electrolytes featuring gradient pores cross-section and varying hydrophilicities on surfaces. This novel enables Zn-ion batteries to exhibit excellent performance.
Rechargeable aqueous zinc-ion batteries (AZIBs) are gaining recognition as promising next-generation energy storage solution, due to their intrinsic safety and low cost. Nevertheless, the advancement of AZIBs is greatly limited by abnormal growth zinc dendrites during cycling. Electrolyte additives effective at suppressing dendrites, but there currently no additive screening criterion. Herein, we propose employing interfacial electrostatic adsorption strength ions for initial additives....
