Constructing new-generation ion exchange membranes under confinement regime

National Science Review, Год журнала: 2024, Номер 12(2)

Опубликована: Ноя. 29, 2024

ABSTRACT Ion exchange membranes (IEMs) enable fast and selective ion transport the partition of electrode reactions, playing an important role in fields precise separation, renewable energy storage conversion, clean production. Traditional IEMs form channels at nanometer-scale via assembly flexible polymeric chains, which are trapped permeability/conductivity selectivity trade-off dilemma due to a high swelling propensity. New-generation have shown great potential break this intrinsic limitation by using microporous framework for under confinement regime. In Review, we first describe fundamental principles charged from nanometer sub-nanometer scale. Then, focus on construction new-generation highlight effects sub-2-nm sub-1-nm further ultra-micropores. The enhanced properties brought intense size sieving channel interaction elucidated, corresponding applications including lithium flow battery, water electrolysis, ammonia synthesis introduced. Finally, prospect future development with respect intricate microstructure observation, in-situ visualization, large-scale membrane fabrication.

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

Regulation of Ion Binding Sites in Covalent Organic Framework Membranes for Enhanced Selectivity under High Ionic Competition

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Март 18, 2025

The strategic spatial positioning of ion affinity sites within biological channels and their cooperative binding with the targeted ions are pivotal for enhancing recognition ensuring exceptional selectivity in high ionic competition scenarios. However, application these principles to artificial remains largely unexplored. Herein, we present a series covalent organic framework (COF) membranes, engineered oxygen functional groups aligned along rims oriented COF pore varying sizes achieve precise arrangement sites. A notable membrane, featuring subnanometer pores decorated alternately carbonyl amide groups, demonstrated outstanding selectivity, achieving Li/Mg ratio 513 under equal mole electrodialysis conditions. Impressively, as Mg/Li source solution increased 16.6, rose 833, significantly exceeding reductions typically seen conventional selective nanofiltration methods. Both simulation experimental analyses indicate that this stems from between Li+ confined nanochannels, facilitating preferential transport ions. These findings provide promising approach designing extraction systems function effectively highly competitive environments.
