The transport of hydrated ions across nanochannels is central to biological systems and membrane-based applications, yet little known about their structure during due the absence in situ characterization techniques. Herein, we report experimentally resolved ion dehydration transmembrane using modified liquid ToF-SIMS combination with MD simulations for a mechanistic reasoning. Notably, complete was not necessary occur membranes sub-nanometer pores. Partial shedding water molecules from...
Dehydration is a basic phenomenon in ion transport through confined nanochannels, but how it affects trans-membrane selectivity has not been understood due to lack of characterization techniques and suitable pore structures. Herein, hydration number distributions typical alkali metal ions were characterized by combining uniform subnanochannels ZIF-8-based membranes with the situ liquid time-of-flight secondary mass spectrometry (ToF-SIMS) technique, revealing that steric hindrance induced...
A novel electrocoagulation membrane reactor (ECMR) was developed, in which ultrafiltration (UF) modules are placed between electrodes to improve effluent water quality and reduce fouling. Experiments with feedwater containing clays (kaolinite) natural organic matter (humic acid) revealed that the combined effect of coagulation electric field mitigated fouling ECMR, resulting higher flux than conventional combination UF separate units (EC-UF). Higher current densities weakly acidic pH EMCR...
Enhanced Donnan repulsion through increase in capacitive ions contributes to the remarkable salt rejection ability of GCM under electrochemical assistance.
Electrocatalytic oxidation offers opportunities for sustainable environmental remediation, but it is often hampered by the slow mass transfer and short lives of electro-generated radicals. Here, we achieve a four times higher kinetic constant (18.9 min-1) 4-chlorophenol on reactive electrochemical membrane reducing pore size from 105 to 7 μm, with predominate mechanism shifting hydroxyl radical direct electron transfer. More interestingly, such an enhancement effect largely dependent...
Antibacterial modification is a chemical-free method to mitigate biofouling, but surface accumulation of bacteria shields antibacterial groups and presents significant challenge in persistently preventing membrane biofouling. Herein, great synergistic effect electrorepulsion quaternary ammonium (QA) inactivation on maintaining activity against biofouling has been investigated using an electrically conductive QA (eQAM), which was fabricated by polymerization pyrrole with compounds. The...
