Confinement boosted heterogeneous advanced oxidation processes

Chemical Engineering Journal, Journal Year: 2023, Volume and Issue: 472, P. 144861 - 144861

Published: July 25, 2023

Confined catalysts with large surface areas and adjustable pore channel sizes have been recently used in advanced oxidation processes (AOPs) for water wastewater treatment. Typically, a confinement scale depends on the geometric structure of catalyst. In environment AOPs, hydrogen bond number, ionic hydration diffusion molecules, adsorption energy chemical length oxidants as well local concentrations migration distances active species can be strikingly affected, turn influencing catalytic degradation efficiency. catalysis will generally enhance interaction between pollutants, increasing reaction kinetics improving contaminant removal compared traditional non-confined catalysis. this review, we firstly summarized behaviors different confined systems. Then elaborated entire AOPs from oxidant activation, generation function catalysis, focusing changes molecular behavior elucidating mechanism activation at level At last, presented suggestions perspectives AOPs. This review was believed to shed new light design catalysts, contributing contaminants efficiently selectively

Conjugated Microporous Polymers‐Based Catalytic Membranes with Hierarchical Channels for High‐Throughput Removal of Micropollutants

Advanced Science, Journal Year: 2024, Volume and Issue: 11(29)

Published: June 3, 2024

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
