Abstract Engineering a catalytic membrane capable of efficiently removing emerging organic microcontaminants under ultrahigh flux conditions is significance for water purification. Herein, drawing inspiration from the functional attributes lymphatic vessels involved in immunosurveillance and fluid transport with minimal energy consumption, novel hierarchical porous engineered. This membrane, based on an innovative nitrogen‐rich conjugated microporous polymer (polytripheneamine, PTPA), synthesized using electrospinning coupled situ polymerization approach. The resulting bioinspired channels comprises thin layer (≈1.7 µm) crosslinked PTPA nanoparticles covering interconnected electrospun nanofibers. unique design creates intrinsic angstrom‐confined system activating peroxymonosulfate (PMS) to generate 98.7% singlet oxygen ( 1 O 2 ), enabling durable highly efficient degradation microcontaminants. Additionally, presence mesoporous structure between macroporous within interwoven nanofibers enhances mass transfer efficiency facilitates high rates. Notably, prepared demonstrates enduring high‐efficiency performance superior permeance (>95% >2500 L m −2 h −1 bar ) sustained over 100 h. work introduces pathway high‐performance membranes removal

In Situ Growth of Robust 2D ZIF‐67 MOF in Block Copolymer Membranes for Ultrafast Molecular Degradation

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 18, 2025

Abstract Membrane‐based advanced oxidation processes (AOPs) rely heavily on the configuration of membrane structures and catalysts. However, designing state‐of‐the‐art integrated with tailored catalysts for efficient AOPs remains a significant challenge. In this study, first time, hybrid membranes are constructed by in situ growth 2D ZIF‐67 onto nanopore walls 3D block copolymer (BCP) membranes. These feature highly tunable pore structures, leading to exceptional catalytic performance that surpasses previously reported The remarkable efficiency stems from predominant role non‐radical species, 1 O 2 , degradation, combined integration high‐surface‐area tortuous BCP resulting demonstrate robust performance, achieving stable permeance over 1800 L (m ·bar·h) −1 while completely degrading dyes during long‐term filtration. Notably, degradation is maintained at 90% even when adjusted 3070 . Additionally, exhibit excellent resistance both alkali acidic environments unaffected various background anions or types degraded molecules.
