This paper comprehensively elucidates the activation mechanisms of PAA and reviews cutting-edge activation strategies, including external energy input, metallic/non-metallic catalysts, and natural anion-mediated pathways. It also delves into the critical factors influencing PAA activation, analyzing their interplay in complex water quality conditions. Research indicates that PAA demonstrates robust oxidative capacity under various activation methods, markedly enhancing pollutant removal efficiency. However, in practical applications, complex water matrix components can significantly impact PAA activation, leading to quenching of reactive species and catalyst deactivation. This study further proposes optimization strategies for complex water matrices to improve the adaptability and stability of PAA-based advanced oxidation processes (PAA-AOPs). Furthermore, this paper highlights the synergistic activation mechanisms of PAA, wherein radical and non-radical pathways coexist and complement each other to enhance pollutant degradation efficiency. Such synergy not only broadens the reactivity spectrum of PAA but also improves its selectivity and stability under complex aqueous conditions. The review details how tailored combinations of activation methods facilitate multi-path oxidation, achieving improved removal of persistent pollutants and microbial pathogens. These insights underscore the transformative potential of synergistic activation in advancing next-generation water purification technologies.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"8 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145288659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, reduced graphene oxide (rGO) adsorbents were developed via controlled hydrothermal reduction of GO resulting, after optimizing the synthesis conditions with respect to the type of reducing agent and reduction reaction duration, in reversed selectivity for the removal of ethane from ethylene-rich mixtures. The optimum adsorbent, prepared by using hydrazine hydrate as reducing agent and a 4-h reduction treatment time (rGO-4-H), exhibited a high ethane capacity of 3.45 mmol/g at 273 K and 1 bar and a kinetic selectivity of 2.4, with low heat of adsorption (24 kJ/mol for C₂H₆) ensuring facile regeneration. Atomic force microscopy was used to measure the weak van der Waals interactions of ethane and ethylene with the rGO surface, while molecular dynamics simulations indicated that both ethane and ethylene exhibit heats of adsorption in the range of 10–40 kJ/mol that tend to increase with the oxygen content of the adsorbent, with ethane under certain conditions showing stronger adsorption than ethylene thus explaining the experimentally observed reverse selectivity.

In this study, a bacterial strain A-1 with exceptional glyphosate-degrading capacity was isolated and identified as <em>Ochrobactrum</em> sp. After optimization, this strain can completely remove 100 mg·L⁻¹ glyphosate within 24 h. During the degradation of low concentrations of glyphosate (50–400 mg·L⁻¹), A-1 maintained homeostasis between reactive oxygen species (ROS) generation and scavenging. However, high concentrations (&gt;800 mg·L⁻¹) induced cellular physiological dysfunction, as characterized by a decrease in cell membrane potential and a burst of ROS, ultimately leading to bacterial apoptosis. Genomic analysis revealed that A-1 has evolved multiple glyphosate metabolic pathways, with 41 identified degradation-related genes.

At 16 h post-inoculation, the degradation capabilities of the Δ<em>phn</em> mutant (which nearly lost all degradation ability) and the Δ<em>goxY6</em> mutant (exhibiting a 25.37 % reduction) were significantly lower compared to the wild type.

Metal-organic frameworks (MOFs) boast tunable pore structures, a high specific surface area, and numerous active sites, providing unique advantages for Na<img alt=\"single bond\" src=\"https://sdfestaticassets-us-east-1.sciencedirectassets.com/shared-assets/55/entities/sbnd.gif\" style=\"vertical-align:middle\"/>S batteries. This work describes the synthesis of nitrogen-doped porous carbon (N-MPC) through the pyrolysis and acid etching of the MIL-88-NH₂ precursor. This process achieves a high specific surface area and a hierarchical pore structure. The micropores effectively limit the dissolution of sodium polysulfides (NaPSs), while the mesopores create space for sulfur loading and ion transport channels. The nitrogen-doped sites serve as Lewis bases, thereby enhancing the chemical adsorption of NaPSs. The doping process introduces defects that improve the conductivity of the carbon matrix, and significantly diminish the shuttle effect. By combining <em>in situ</em> Raman spectroscopy and <em>ex-situ</em> XRD/XPS, the “solid-liquid-solid” reaction pathway (S₈ → Na₂S_4–8 → Na₂S) was uncovered, confirming the role of N-MPC in promoting the efficient conversion of long-chain polysulfides (Na₂S_4–8) to short-chain sulfides (Na₂S).

Thus, many strategies focus on strong, tough, stable, durable, antifreeze, etc. However, fabrication of all-around performance gel still faces a challenge. Usually, conductive gels hardly meet the above merits. Thus, we fabricate an organic gel with the merits of toughness without sacrificing strength, long-term stability, anti-freezing, and durability by direction-freezing assisted non-solvent solution quenching (DF-NSQ). Directional freezing promotes the alignment of PVA molecular chains in accordance with the temperature gradient direction. Poly (ethylene glycol) (PEG-200) as a non-solvent induces PVA-oriented ice crystal in-situ phase separation, promoting PVA chains closer and bolstering inter-chain interaction. Meanwhile, the synergistic coordination of ferric chloride (FeCl₃) enhances PVA aggregation. The resultant organic gel shows excellent mechanical properties (Strength: 8.25 MPa, Strain: 800 %, Toughness: 35 MJ/m³, Fracture toughness: 82.2 KJ/m², and Young's modulus: 2.35 MPa) and long-term stability (&gt;90 days) with 10%PVA and 1 % FeCl₃/PEG200 solution. Then, such an organic gel used as a flexible sensor exhibits freezing tolerance (Working at −20 °C), underwater sensing characteristics, electrical stability (cycles&gt;40,000 with 30 %), and a wide working window (0–800 %).

Their inherent sensitivity, selectivity, and long-term stability underpin their utility in gas-sensing technologies. This review presents a comprehensive assessment of recent advancements in ABO₃-based perovskite gas sensors, with a focus on contemporary synthesis techniques, structural modification strategies, and underlying sensing mechanisms that contribute to enhanced room-temperature operation. Particular attention is given to the role of surface morphology, nanostructure topography, and redox-driven interactions in materials such as BaSnO₃, CdSnO₃, ZnSnO₃, SrTiO₃, LaFeO₃, LaCoO₃, BaTiO_3, and CdTiO₃. Key enhancement strategies including transition metal doping, noble metal functionalization, nanostructuring, and heterojunction formation have enabled significant improvements in sensor sensitivity, selectivity, and operating temperature. Recent efforts to integrate ABO₃ perovskites with 2D materials, carbon nanostructures, and plasmonic catalysts have shown promise in addressing persistent challenges such as humidity interference, limited selectivity, and integration with flexible or miniaturized platforms. This review aims to deepen the understanding of gas-sensing mechanisms in ABO₃ perovskites, critically examine current progress, and propose future research directions for practical implementation.

While conventional adsorption techniques can effectively capture these particles, they often fall short of achieving complete mineralization. In contrast, photocatalytic degradation enables molecular-level breakdown but is frequently hampered by poor stability and recyclability. To overcome these limitations, research is increasingly turning to bio-based materials, porous functional frameworks, and their hybrid composites as sustainable platforms for comprehensive microplastic remediation. This review systematically examines the fundamental mechanisms of adsorption and photocatalytic degradation, highlighting recent advances in bio-based materials (e.g., cellulose, chitosan) and porous frameworks (e.g., MOFs, COFs, and HOFs), as well as their synergistic combinations. Bio-based materials offer advantages including environmental compatibility, abundant functional groups, and renewable sourcing. Porous frameworks contribute tunable pore architectures, high surface areas, and pronounced photocatalytic activity. The strategic integration of these components creates composites that leverage their complementary strengths—enhancing adsorption capacity, facilitating interfacial charge transfer, and improving structural integrity—thereby enabling efficient and recyclable removal under realistic conditions. Furthermore, this review critically assesses the ecotoxicological safety, potential for metal ion leaching, and associated environmental risks of these materials. It incorporates techno-economic (TEA) and life-cycle assessments (LCA) to evaluate their scalability and overall sustainability. Finally, we emphasize the promising “waste-to-product” strategy, which converts agricultural and industrial residues into functional hybrid frameworks, thereby aligning microplastic remediation with the principles of a circular economy.

While extensive efforts have been devoted to modulating color transitions from static to dynamic ordered states, reversible transformations between ordered and disordered states remain largely underexplored. Herein, drawing inspiration from microphase separation mechanisms, we report water-triggered dynamic stiffening and structural chromism in CPCs by integrating silica nanoparticles (SiNPs) into a PEG-gel network formed from Poly(PoMA-HEMA-AAc). The pronounced affinity contrast between PEG and water induces rapid and reversible stiffening upon hydration. Simultaneously, this dual-phase morphology disrupts the periodic arrangement of SiNPs, causing the structural color to fade from iridescent hues to a disordered, colorless white. Benefiting from the excellent commercial availability, modularity, and designability of the polymer components, these CPCs hold significant promise for biomedical applications. In particular, the hydration-induced mechanical reinforcement effectively reduces skin tension at wound sites, mitigating scar formation and accelerating healing. Moreover, the distinct chromism provides visual feedback on wound exudate absorption and healing progression, supporting its clinical potential for intelligent wound care with autonomous mechanical adaptation and real-time diagnostic capability. <em>In vivo</em> studies on murine full-thickness wounds demonstrate that the PEG-gel patch accelerates healing by 40 % compared to conventional hydrogels, achieving 96 % re-epithelialization and reduced scar formation.
