“…Typical fabrication methods for functionalizing IEMs with noble metal NPs can be categorized into physical and chemical methods (details are provided in Table S3). Physical methods (e.g., physical vapor deposition (PVD), dip coating, spray coating, and filtration coating) utilize physical processes such as adsorption, complexation, or hydrogen bonding to form a coating layer on the membrane surface. − Chemical methods form chemical bonds between noble metal NPs and the IEM surface, improving the stability of the noble metal NPs . Currently, PVD, filtration coating, dip coating, electroplating, and sol–gel have been applied to functionalize the IEM with noble metal NPs. ,,,, In this section, we briefly review the current and potential methods that can be used in fabricating noble metallic IEMs.…”

Decentralized water systems necessitate intensified, robust, and modular water treatment technologies for enhanced efficacy and resilience of the water purification process. Inorganic electrified membranes (IEMs) are gaining momentum in decentralized water systems by combining the versatility of electro-filtration processes with the favorable properties of inorganic materials, namely, strong mechanical strength, chemical stability, and hydrophilicity. This review quantitatively assesses three mainstream IEMs (i.e., Ti4O7, carbon, and metallic IEMs) from a fundamental perspective of the intrinsic electrochemical properties of the IEM materials and their translation into the IEM performances. We specifically (i) analyze the •OH production selectivity by Ti4O7 IEMs based on electrochemical thermodynamics and material science; (ii) differentiate degradation mechanisms of carbon IEMs in the context of various water matrices and propose strategies to address major concerns of avoiding membrane passivation and improving Faradaic efficiency of carbon IEMs; and (iii) highlight metallic IEMs doped with Ag or Pd, i.e., elucidate the combined sterilization mechanism by Ag-IEM via Ag+ dissolution and electro-phenomena, and unravel the unique hydrogenolysis ability of Pd-IEM for hydrodeoxygenation and persulfate electro-activation. We conclude by identifying the remaining obstacles of IEMs and present possible interdisciplinary approaches for IEM optimization.

In this research, the CuFeS2/MXene-modified polyvinylidene fluoride (PVDF) membrane was prepared to activate peroxymonosulfate (PMS) to remove moxifloxacin (MOX) and its morphology; surface functional groups and hydrophilicity were also studied. The parameters of the catalytic membrane/PMS system were optimized, with an optimal loading of 4 mg/cm2 and a PMS dosage of 0.20 mM. High filtration pressure, alkaline conditions, and impurities in water could inhibit MOX removal. After continuous filtration, the removal efficiency of MOX using the catalytic membrane/PMS system and PVDF membrane was 68.2% and 9.9%, respectively. Batch filtration could remove 87.8% MOX by the extra 10 min contact time between the catalytic membrane and solution. During the filtration process, CuFeS2/MXene on the surface of the catalytic membrane activated PMS to produce SO4•−, HO•, and 1O2, and MOX was removed through adsorption and degradation. Taking humic acid (HA) as the model foulant, reversible fouling resistance in the catalytic membrane/PMS system was 22.8% of the PVDF membrane. The catalytic membrane/PMS system weakened the formation of the cake layer by oxidizing HA into smaller pollutants and followed the intermediate blocking cake filtration model. The novelty of this research was to develop a CuFeS2/MXene–PVDF membrane-activated PMS system and explore its application in antibiotics removal.

“…Membrane technology, especially the low-pressure membranes (LPMs) including microfiltration (MF) and ultrafiltration (UF), has been widely applied for surface water treatment on account of its merits, including highly selective separation, easy scale-up, and sustainability. , However, the various organic components in surface water, such as natural organic matters (NOMs) and anthropogenic organic microcontaminants (e.g., pharmaceuticals, pesticides, and dyestuffs), inevitably exacerbate the fouling of the membranes and leakage of organic microcontaminants, resulting in attenuated efficiency and higher energy consumption, hampering its efficient application. , To address these issues, various LPM-based techniques have been proposed and developed. Advanced oxidation processes (AOPs) as oxidative reactive oxygen (ROS)-mediated technology can mineralize the organic components into harmless substances. , For instance, hydroxyl radicals (•OH, E 0 = 2.80 V/NHE) generated from the reaction between H 2 O 2 and Fe(II) in the electro-Fenton (EF) process have strong oxidized capabilities, which can achieve robust decontamination performance .…”

Regulation of the fast electron transport process for the generation and utilization of reactive oxygen species (ROS) by achieving fortified electron "nanofluidics" is effective for electrocatalytic oxidation of organic microcontaminants. However, limited available active sites and sluggish mass transfer impede oxidation efficiency. Herein, we fabricated a conductive electrocatalytic membrane decorated with hierarchical porous vertically aligned Fe(II)-modulated FeCo layered double hydroxide nanosheets (Fe(II)-FeCo LDHs) in an electro-Fenton system to maximize exposure of active sites and expedite mass transfer. The nanospaced interlayers of Fe(II)-FeCo LDHs within the microconfined porous structure formed by its vertical nanosheets highly boost the micro/nanofluidic distribution of target pollutants to active centers/species, achieving accelerated mass transferability. Aliovalent substitution by Fe(II) activates in-plane metallics to maximize the available active sites and makes each Fe(II)-FeCo LDH nanosheet a geometrical nanocarrier for constructing a fast electron "nanofluidic" to accelerate Fe(II) regeneration in Fe(III)/Fe(II) cycles. As a result, the Fe(II)-FeCo LDHs exhibited improved reactivity in catalyzing H 2 O 2 to •OH and 1 O 2 . Accordingly, the membrane exhibited a higher atrazine degradation kinetic (0.0441 min −1 ) and degradation rate (93.2%), which were 4.7 and 2.1 times more than those of the bare carbon nanotube membrane, respectively. Additionally, the enhanced hydrophilic and strongly oxidized reactivity synergistically mitigated the organic fouling occurring in the pores and surface of the membrane. These findings clarify the activation mechanism of ROS over an innovative electrocatalytic membrane reactor design for organic microcontaminant treatment.
