To address this issue, a series of CuZn layered double hydroxide/carbon nitride (denoted as CuZn/CN-x) heterojunction adsorbents with varying CuZn/CN ratios was fabricated through a facile one-step hydrothermal protocol. These materials were comprehensively characterized using multiple analytical techniques, and their adsorption performances were assessed for the removal of tetracycline hydrochloride (TC). Experimental results showed that all synthesized CuZn/CN-x composites exhibited typical hydrotalcite-like structures and graphite-like conjugated frameworks. Under optimal conditions, the maximum adsorption capacity of the CuZn/CN-150 reached 3841 mg·g‒1. Thermodynamic and kinetic investigations demonstrated that the adsorption process followed the pseudo-second-order kinetic and Langmuir isotherm models, suggesting a spontaneous and endothermic reaction that is susceptible to solution pH and coexisting ions. The adsorption mechanism was found to be driven by the synergistic effect of multiple interactions, including electrostatic attraction, hydrophobic interaction, and weak metal complexation. Moreover, the CuZn/CN-150 sample displayed outstanding recyclability and structural stability, maintaining a TC removal efficiency of over 90% even after 10 successive adsorption-desorption cycles.

In this work, exsolution of Ni from NiAl-layered double hydroxide (LDH) produces a well-defined family of Ni/Al2O3 catalysts for the steam reforming of methane (SRM) to hydrogen. Increasing the calcination temperature of 40 wt% NiAl-LDH from 400–900 °C (prior to a common reduction protocol) resulted in exsolved Ni nanoparticles of systematically increasing size from 4 to 18 nm diameter on an amorphous alumina support. In contrast, wet-impregnation of commercial alumina by Ni(NO3)2 resulted in ∼39 nm Ni nanoparticles at a similar metal loading. SRM exhibited a strong structure-sensitivity, being favored over smaller particles with 80 % methane conversion and a high specific hydrogen productivity of 0.37 mmol.g−1Ni.s−1 for Ni particles ≤8 nm at 700 °C, falling to 40 % conversion and 0.08 mmol.g−1Ni.s−1 for 39 nm particles (for wet-impregnated Ni/Al2O3). Selectivity to H2 versus CO/CO2 mirrored this structure-sensitivity, with smaller Ni particles delivering ≥75% selectivity >450 °C, falling to 65 % over large particles. Exsolved Ni particles derived by 500 °C calcination exhibited excellent stability for at least 24 h time-on-stream, with negligible coking, offering Earth-abundant catalysts for hydrogen production from simple precursors.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"18 13","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.70874","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148373088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigates how microemulsion structure, governed by surfactant identity, controls the formation and catalytic behavior of Au, Pt, and Au–Pt/TiO2 nanoparticles in base-free glucose oxidation. Two contrasting surfactants were examined: AOT (rigid ionic film) and Triton X (flexible nonionic film). TEM analysis showed that AOT produces significantly smaller and more uniform nanoparticles than Triton X (Au: 6.5 vs. 12.0 nm; Pt: 1.6 vs. 15.6 nm; Au50Pt50: 4.7 vs. 8.6 nm). STEM–EDX and XPS indicate that AOT favors compositionally heterogeneous structures with Au-rich cores and Pt-enriched surfaces, while Triton X leads to alloy-like particles. These structural differences result in distinct catalytic behavior: AOT-derived catalysts exhibit higher activity due to smaller size and greater surface accessibility. Au-AOT achieves near-complete glucose conversion with 88.7% selectivity toward gluconic acid, while Pt primarily tunes selectivity toward deeper oxidation products. Stability studies suggest deactivation arises mainly from surface restructuring and metal redistribution rather than sintering. Overall, surfactant-controlled synthesis provides an effective strategy to tune activity and selectivity in Au–Pt/TiO2 catalysts.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"18 13","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.70893","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148373090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular docking revealed that the mutations widened and enhanced the hydrophobicity of the amine-binding pocket, strengthening interactions with bulky aliphatic amines.

Compared with conventional hydroxyl radical–dominated systems, persulfate activation can generate a wider spectrum of reactive species, including sulfate radicals, hydroxyl radicals, singlet oxygen, high-valent metal–oxo species, and surface-mediated reactive species. While this mechanistic diversity provides opportunities for efficient pollutant degradation, the simultaneous presence of multiple pathways often leads to complex reaction networks and obscures mechanistic interpretation. Recent studies therefore emphasize controlling, rather than maximizing, reactive species generation by steering the system toward a dominant pathway. This review summarizes recent progress in regulating persulfate activation pathways through both catalyst design and reaction environment. Intrinsic strategies, such as heteroatom doping, defect engineering, coordination modulation, and nanoconfinement, regulate the electronic structure of catalysts and determine the preferred activation mode. Extrinsic factors, including water matrix composition, external fields, and pollutant properties, can further shift the balance between radical and non-radical pathways.
