Abstract Polyester nanofiltration membranes highlight beneficial chlorine resistance, but their loose structures and negative charge result in poor cations retention precluding advanced use separation. This work designs a new monomer (TET) containing “hydroxyl‐ammonium” entities that confer dense positive to polyester membranes. The TET undergoes efficient interfacial polymerization with the trimesoyl chloride (TMC) monomer, resultant TET‐TMC feature one of lowest molecular weight cut‐offs (389 Da) highest zeta potential (4 mv, pH: 7) among all MgCl 2 rejection membrane is 95.5%, significantly higher than state‐of‐the‐art (<50%). Li + /Mg 2+ separation performance on par cutting‐edge polyamide membranes, while additionally, stable against NaClO though readily degrade. Thus first for

Abstract The application of homogeneous catalysts in water remediation is limited by their excessive chemical and energy input, weak regenerability, potential leaching. Heterogeneous catalytic membranes (CMs) offer a new approach to facilitate efficient, selective, continuous pollutant degradation. Thus, integrating filtration with heterogeneous advanced oxidation processes (AOPs) can promote thermodynamic kinetic mass transfers spatially confined intrapores diffusion‐reaction processes. Despite the remarkable advantages CMs, engineering practically restricted due fuzzy design criteria for specific applications. Herein, recent advances CMs are critically reviewed flow tempospatially proposed. Further, state‐of‐the‐art CM materials mechanisms reviewed, after which tempospatial confinement comprising nanoconfinement effect, interface transfer emphasized, thus clarifying roles construction performance optimization CMs. Additionally, fabrication methods based on pore sizes summarized an overview evaluations presented. Finally, future directions research treatment,

Thin-film composite polyamide (TFC PA) membranes hold promise for energy-efficient liquid separation, but achieving high permeance and precise separation membrane via a facile approach that is compatible with present manufacturing line remains great challenge. Herein, we demonstrate the use of lignin alkali (LA) derived from waste paper pulp as an aqueous phase additive to regulate interfacial polymerization (IP) process performance nanofiltration (NF) membrane. Various characterizations molecular dynamics simulations revealed LA can promote diffusion partition monomer piperazine (PIP) molecules into organic their uniform dispersion on substrate, accelerating IP reaction promoting greater instabilities, thus endowing formation TFC NF ultrathin, highly cross-linked, crumpled PA layer.

Abstract Covalent organic framework (COF) membranes featuring uniform topological structures and devisable functions, show huge potential in water purification molecular separation. Nevertheless, the inability of COF to be produced on an industrial scale their nonenvironmentally friendly fabrication method are bottleneck preventing applications. Herein, we report a new green industrially adaptable scraping‐assisted interfacial polymerization (SAIP) technique fabricate scalable TpPa membranes. The process used non‐toxic low‐volatility ionic liquids (ILs) as phase instead conventional solvents for synthesis layer support membrane, which can simultaneously achieve purposes (i) improving greenness membrane‐forming (ii) fabricating robust membrane that function beyond This approach yields large‐area, continuous (19×25 cm 2 ) with thickness 78 nm within brief period minutes. resulting exhibited unprecedented combination high permeance (48.09 L m −2 h −1 bar antibiotic desalination efficiency (e.g., NaCl/adriamycin separation factor 41.8), is superior commercial benchmarking
