Utilizing pore and interlayer engineering within nanoconfined interlaminar channels represents an ingenious approach to design highly permselective MXene (Ti3C2TX) membranes. Herein, the tannic acid (TA) etched ZIF-8 (TZIF-8) nanocrystals with hollow structures were effectually inserted into spacing of First, density functional theory (DFT) results demonstrated reaction mechanism between TA ZIF-8. Then, underlying enhanced water-adsorptive properties for MXene/TZIF-8 membrane was due higher binding energy water/TZIF-8 system than that water/ZIF-8 system, elucidated by molecular dynamic simulation. Furthermore, low mass transfer resistance abundant pathways comprehensively proved various experimental conclusions, characterizations simulation calculations. As a result, optimal exhibited high water permeance concurrently satisfactory separation efficacy toward oil/water emulsions. This work is anticipated deepen comprehension high-efficiency transport along interbedded nanochannels in

Spatial Size Manipulation of 1D/2D Channels in Covalent Organic Framework Membranes Through Dopamine Chemistry for Ion Separations

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Окт. 22, 2024

Abstract Covalent organic framework (COF) membranes feature with well‐developed 1D in‐plane pores and parallelly arranged 2D interlayer gallery, presenting promising platform for precise separations. However, it remains a formidable challenge to construct regulate membrane channels at angstrom scale. Herein, pH‐sensitive dopamine is taken advantage elaborately engineer the spatial size of 1D/2D in COF separations alkali metal ions. Acid treatment allows monomolecular segment membrane, achieving ultramicroporous regulation from 1.25 nm 0.71 nm, which enables high selectivity 18.7 K + /Li separation. Molecular dynamics simulations reveal higher dehydration degree, weaker channel‐cation interaction faster diffusion coefficient than Li . For alkaline treatment, self‐polymerizes form nanoparticles between layers, enlarges 0.33 0.45 enabling high‐permeance ion/molecule The water permeance increases 86.7% 404 L m −2 h −1 bar , without sacrifice sieving ability. Both cation separation performances outperform current state‐of‐the‐art membranes. This dopamine‐mediated channel engineering strategy may provide new insights design
