Mono-/multivalent ion-selective separation has become a common requirement at the water-energy nexus, including energy storage and conversion, water purification, sustainable industrial processes. In this review, we summarize theory of ion transport through membrane mechanisms selective in nanofiltration (NF) briefly. Recent advancing improving mono-/multivalent selectivity thin-film composite (TFC) NF via size sieving enhancement, electric charge property regulation co-enhancement properties are concluded. What's more, three material classes—surface assembly materials, nanomaterials biomimetic channels highlighted as candidates for preparation membranes. Lastly, design directions critical challenges developing high-selectivity membranes based on provided.

Fast permeation and effective solute-solute separation provide the opportunities for sustainable water treatment, but they are hindered by ineffective membranes. We present here construction of a nanofiltration membrane with fast permeation, high rejection, precise Cl-/SO42- spatial temporal control interfacial polymerization via graphitic carbon nitride (g-C3N4). The g-C3N4 nanosheet binds preferentially piperazine tiles water-hexane interface as revealed molecular dynamics studies, thus lowering diffusion rate PIP one order magnitude restricting its pathways towards hexane phase. As result, membranes nanoscale ordered hollow structure created. Transport mechanism across is clarified using computational fluid simulation. Increased surface area, lower thickness, identified key contributors to permeance 105 L m2·h-1·bar-1 Na2SO4 rejection 99.4% selectivity 130, which superior state-of-the-art NF Our approach tuning microstructure enables development ultra-permeability excellent ion-ion separation, purification, desalination, organics removal.

Abstract Current polyamide lithium extraction nanofiltration membranes are susceptible to chlorine degradation and/or low permeance, two problems that hard reconcile. Here we simultaneously circumvented these by designing a quaternized-spiro piperazine monomer and translating its beneficial properties into large-area (1 × 2 m ) via interfacial polymerization with trimesoyl chloride. The quaternary ammonium spiral conformation of the confer more positive charge free volume membrane, leading one highest permeance (~22 L −2 h −1 bar compared state-of-the-art Mg 2+ /Li + membranes. Meanwhile, membrane structures resistant as amine–acyl bonding contains no sensitive N-H group. Thus high performance is stable versus 400-h immersion in sodium hypochlorite, while control degraded readily. Molecular simulations show resistance, which were reproducible at module level, arise from secondary amine monomer.
