The regulation of peroxymonosulfate (PMS) activation by photo-assisted heterogeneous catalysis is under in-depth investigation with potential as a replaceable advanced oxidation process in water purification, yet it remains significant challenge. Herein, we demonstrate strategy to construct polyethylene glycol (PEG) well-coupled dual-defect V

We investigated the photocatalytic activity of TiO2 nanoparticles (TiO2-NPs) and nanotubes (TiO2-NTs) supported on a floating polyurethane (PU) foam for removing Bisphenol A (BPA) as model pollutant. fabricated TiO2-NPs by sol-gel method TiO2-NTs ultrasound-assisted hydrothermal method. Subsequently, photocatalysts were immobilized onto PU through wet chemical deposition process. The synthesized characterized contact angle, SEM-EDS, TEM, XRD, DRS, BET analyses. successfully deposited foam, creating denoted TiO2-NPs@PU TiO2-NTs@PU. Our findings indicated that nanotubular structure enhanced removal efficiency BPA relative to nanoparticles, resulting in complete pollutant over 180 min simulated sunlight irradiation. TiO2-NTs@PU was also stable after five reuse cycles. Moreover, h+ main scavenging reactive species during photocatalysis with

The separation and recovery of useful organics from wastewater have been a promising alternative to tackling water pollution resource shortages, while strategies that truly work rarely explored. Herein, reversible CO2 triggered sol–gel state transformation mediated selective uptake-release system using surface modified carbonitride (S-CN) is proposed exhibits remarkable performance wastewater. Results show can serve as cross-linker for linking S-CN particles form hydrogel by electrostatic interaction hydrogen bonding, which be recycled the pristine sol simply removing cross-linked with Ar purging. achieves nearly complete uptake valuable high selectivity at first sol-to-gel stage through interaction, π–π interactions together, it recovers 90% uptaked releasing them into concentrated solution second gel-back-to-sol stage.

Abstract Heteroatom‐bridged dual‐atom catalysts (DACs), featuring more flexible active sites and intermetallic interaction, provide an opportunity for sustainable environmental remediation. Herein, innovative oxygen‐bridged Co‐Cu DAC supported on nano‐alumina (CoOCu‐DAC) is fabricated using a straightforward two‐step process. The as‐prepared catalyst significantly enhances both decontamination kinetics peroxymonosulfate (PMS) utilization efficiency by 1–3 orders of magnitude toward monoethanolamine (MEA, p K = 9.5) compared to Co single‐atom (Co‐SAC) bulk metal catalysts, largely outperforms previously reported systems. In‐situ ATR‐FTIR theoretical investigations reveal that the secondary introduction Cu plays multiple important roles: it activates lattice oxygen trigger key proton transfer (PT) MEAH + via nucleophilic attack at interface subsequently favors deprotonated MEA as efficient electron donor accelerate (ET) enhancing orbital overlaps co‐activation O 2 PMS. Such stepwise proton‐coupled (PCET)‐enhanced catalytic pathway mediated CoOCu‐DAC fundamentally different from common route identified in Co‐SAC‐involved Fenton‐like system. established binary QSAR further substantiates universality PCET‐enhanced strategy versatile nitrogen‐containing organic compounds. This study offers new perspective water other related areas catalysis based rationalized design multifunctional atomic level.
