Sub-nanoporous membranes with ion selective transport functions are important for energy utilization, environmental remediation, and fundamental bioinspired engineering. Although mono/multivalent ions can be separated by monovalent (MISMs), the current theory fails to inspire rapid advances in MISMs. Here, we apply transition state (TST) regulating enthalpy barrier (ΔH) entropy (ΔS) designing next-generation cation exchange (MCEMs) great improvement separation. Using a molecule-absorbed porous material as an interlayer construct denser layer achieve greater absolute value of ΔS Li

Nanofiltration (NF) membranes play a critical role in separation processes, necessitating an in-depth understanding of their selective mechanisms. Existing NF models predominantly include steric and Donnan mechanisms as primary However, these often fail elucidating the selectivity between ions similar dimensions same valence. To address this gap, innovative methodology was proposed to unravel new by quantifying nominal dielectric effect isolated from exclusion through fitted pore constants regression analysis. We demonstrated that encompassed unidentified significant relevance establishing correlation hindrance factors. Our findings revealed dehydration-induced ion-membrane interaction, rather than ion dehydration, played pivotal partitioning within membranes. This interaction closely linked nondeformable fraction hydrated ions. Further delineation showed favorable interactions membrane functional groups contributed entropy-driven selectivity, which is key factor explaining differences sharing size study deepens our sheds light on design highly for water wastewater treatment.

Abstract Sub‐nanoporous membranes with ion selective transport functions are important for energy utilization, environmental remediation, and fundamental bioinspired engineering. Although mono/multivalent ions can be separated by monovalent (MISMs), the current theory fails to inspire rapid advances in MISMs. Here, we apply transition state (TST) regulating enthalpy barrier (ΔH) entropy (ΔS) designing next‐generation cation exchange (MCEMs) great improvement separation. Using a molecule‐absorbed porous material as an interlayer construct denser layer achieve greater absolute value of ΔS Li + Mg 2+ transport, ΔH lower transport. This recorded performance /Mg perm‐selectivity 25.50 flux 1.86 mol ⋅ m −2 h −1 surpasses contemporary “upper bound” plot separations. Most importantly, our synthesized MCEM also demonstrates excellent operational stability during electrodialysis (S‐ED) processes realizing scalability practical applications.

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.
