Water and ion transport in nanochannels is crucial for membrane-based technology biological systems. 2D materials, especially graphene oxide (GO), the most frequently used as starting material, are ideal building blocks developing synthetic membranes. However, selective exclusion of small ions while maintaining a pressured filtration process remains challenge GO Herein, novel "cation-recognition" effect introduced within reduced (rGO) membranes modified by ionic liquids (IL) to enhance desalination performance. The resulting IL-intercalated rGO (IL-rGO) exhibit remarkable stability even under prolonged exposure acidic basic conditions, without damage or delamination maintain approximately ultrahigh water permeance (≈32.0 L m

Nanofluidics is an interdisciplinary field of study that bridges hydrodynamics, statistical physics, chemistry, materials science, biology, and other fields to investigate the transport fluids ions on nanometric scale. The progress in this field, however, has been constrained by challenges fabricating nanofluidic devices suitable for systematic investigations. Recent advances two-dimensional (2D) have revolutionized development nanofluids. Their ultrathin structure photothermoelectric response make it possible achieve scale control, friction limitation, regulatory response, all which are challenging with traditional solid materials. In review, we provide a comprehensive overview preparation methods corresponding structures three types 2D material-based devices, including nanopores, nanochannels, membranes. We highlight their applications recent exploring physical mechanisms, detecting biomolecules (DNA, protein), developing iontronics improving ion/gas selectivity, generating osmotic energy. discuss facing prospects future advancements field.

Abstract Renewable osmotic energy between seawater and river water shows great potential in meeting global demand. Reverse electrodialysis (RED) technique using ion‐selective membrane is particularly outstanding for its easy operation. Preparing low‐cost large‐area membranes with excellent ion transport characteristics important to promote commercial applications. Herein, prepared by scraping slurry of flocculated GO (graphene oxide)/PAAS (sodium polyacrylate) solution then coated PVA (polyvinyl alcohol)/SA alginate) gel layer. The PVA/SA molecules can penetrate into the through unique micro/meso‐pores, which together increase selectivity, permeability, stability. This achieve a power density 8.65 W m −2 under 50‐fold salinity gradient (NaCl) simulating sea/river junction environment (with testing area 0.0314 mm 2 ). work significantly promotes application preparation membrane.
