Precise and ultrafast ion sieving is highly desirable for many applications in environment-, energy-, resource-related fields. The development of a permselective lamellar membrane constructed from parallel stacked two-dimensional (2D) nanosheets opened new avenue the next-generation separation technology because unprecedented diversity designable interior nanochannels. In this Review, we first discuss construction homo- heterolaminar nanoarchitectures starting materials to emerging preparation strategies. We then explore property-performance relationships, with particular emphasis on effects physical structural features, chemical properties, external environment stimuli transport behavior under nanoconfinement. also present existing potential 2D membranes desalination, recovery, energy conversion. Finally, challenges outline research directions promising field.

Light-responsive and ultrapermeable two-dimensional metal-organic framework membrane for efficient ionic energy harvesting

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: March 8, 2024

Abstract Nanofluidic membranes offer exceptional promise for osmotic energy conversion, but the challenge of balancing ionic selectivity and permeability persists. Here, we present a bionic nanofluidic system based on two-dimensional (2D) copper tetra-(4-carboxyphenyl) porphyrin framework (Cu-TCPP). The inherent nanoporous structure horizontal interlayer channels endow Cu-TCPP membrane with ultrahigh ion allow power density 16.64 W m −2 , surpassing state of-the-art nanochannel membranes. Moreover, leveraging photo-thermal property Cu-TCPP, light-controlled active transport is realized even under natural sunlight. By combining solar salinity gradient, driving force reinforced, leading to further improvements in conversion performance. Notably, light could eliminate need achieving 0.82 symmetric solution system. Our work introduces new perspective developing advanced solar/ionic extends concept notion energy.

Nanofiltration (NF) has the potential to achieve precise ion–ion separation at subnanometer scale, which is necessary for resource recovery and a circular water economy. Fabricating NF membranes selective ion highly desirable but represents substantial technical challenge. Dipole–dipole interaction mechanism of intermolecular attractions between polar molecules with dipole moment due uneven charge distribution, such an not been leveraged tune membrane structure selectivity. Herein, we propose novel strategy tunable surface polyamide by introducing solvent large during interfacial polymerization, in dipole–dipole acyl chloride groups trimesoyl (TMC) can successfully intervene amidation reaction alter density carboxyl layer. As result, prepared positively charged (PEI-TMC)-NH2 negatively (PEI-TMC)-COOH composite membranes, show similarly high permeance, demonstrate separations cations anions engineering applications, respectively. Our findings, first time, confirm that solvent-induced interactions are able type efficient separation.

Over the last few decades, developing ultra-permeable nanofiltration (UPNF) membranes has been a focus research area to support NF-based water treatment. Nevertheless, there have ongoing debates and doubts on need for UPNF membranes. In this work, we share our perspectives why are desired We analyze specific energy consumption (SEC) of NF processes under various application scenarios, which reveals potential reducing SEC by 1/3 2/3 depending prevailing transmembrane osmotic pressure difference. Furthermore, could potentially enable new process opportunities. Vacuum-driven submerged NF-modules be retrofitted existing water/wastewater treatment plants, offering lower cost compared conventional systems. Their use in membrane bioreactors (NF-MBR) can recycle wastewater into high-quality permeate water, enables energy-efficient reuse single step. The ability retaining soluble organics may further extend NF-MBR anaerobic dilute municipal wastewater. Critical analysis development huge rooms attain improved selectivity antifouling performance.
