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

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
