Nanoplastic (NPs) pollution represents one of the most persistent environmental crises of our time, requiring breakthrough material technologies for effective remediation. In this study, we engineer a semi-flexible micro-nano structured N-modified cellulose nanofibers@layered double hydroxide (N-CNF@LDH) composite aerogel through a dynamic hydrogen bonding and coordination interactions to achieve efficient removal of NPs, in which the LDH nanoflower clusters are uniformly anchored on the nitrogen-modified cellulose honeycomb skeleton. Under the action of dynamic hydrogen bonds, the structure undergoes spontaneous reorganization at new equilibrium positions upon release of external force, leading to a reversible opening-closing motion within the floral clusters. This design enables ultrahigh NPs adsorption (3648 mg·g −1 ) through reversible inter-petal channel opening, while compression-triggered petal contraction achieves instantaneous release (96% within only 10 s), exhibiting a desorption kinetics rate nearly three orders of magnitude higher than conventional adsorbents. Besides, the dynamic network enables rapid structural reconstruction of N-CNF@LDH through H-bond assembly, maintaining 80.4% NPs capacity and 95.2% shape recovery after 100 cycles. Exhibiting outstanding NPs removal performance in various real-world water systems while remaining cost-effective, this material breaks through the fundamental capacity-regeneration compromise in environmental remediation.

This study presents a facile one-pot hydrothermal strategy for the in-situ growth of a layered double hydroxide and ZIF-8 composite coating on anodic aluminum oxide. The synthesis temperature was optimized within the range of 110–130 °C, which enables the synchronous formation of a uniform and well-interlocked LDH/ZIF-8 microstructure. Subsequent modification with stearic acid (SA) effectively imparts hydrophobicity to the coating, yielding a water contact angle of 136.4 ± 0.10°. The obtained LDH/ZIF-8@SA coating exhibits remarkable anti-icing performance, delaying ice nucleation and complete freezing of a water droplet at -15 °C by 93% and 45%, respectively, compared to the bare AAO substrate. Electrochemical tests demonstrate excellent corrosion resistance, with the SA-modified coating showing a corrosion current density of 1.413 × 10 -9 A·cm -2 after 3 days of immersion, and a charge-transfer resistance up to 1.362 × 10 8 Ω·cm 2 after 14 days of immersion in 3.5 wt.% NaCl solution. Moreover, the coating possesses a low friction coefficient of 0.318 ± 0.045. Density functional theory calculations were performed to elucidate the interfacial bonding mechanism among ZIF-8, SA and LDH.

Mild hydrothermal strategy well preserves abundant O/N functional groups of Chitosan-derived amorphous carbon. • Chitosan-derived amorphous carbon efficiently stabilizes intrinsic Ni 3+ active sites. • Pre‑stabilized intrinsic Ni 3+ promotes the reconstruction of γ‑NiOOH. • Interfacial electronic modulation lowers UOR overpotential and delivers remarkable UOR activity. Replacing the sluggish oxygen evolution reaction (OER) with the urea oxidation reaction (UOR) offers a promising route for energy-efficient hydrogen production and the electrochemical treatment of urea-containing wastewater. However, the practical application of UOR is still hindered by insufficient anode durability and sluggish UOR kinetics. Herein, biomass chitosan was employed as the carbon precursor to fabricate amorphous carbon-modified coral-like NiFe layered double hydroxide (NiFe-LDH), which was in-situ anchored on nickel foam via a facile one-step hydrothermal strategy. The optimized catalyst achieved remarkable UOR electrocatalysis, requiring only 0.94 V and 0.96 V overpotential to reach 50 mA·cm −2 and 100 mA·cm −2 , respectively, accompanied by a small Tafel slope of 22 mV·dec −1 and outstanding long-term stability exceeding 1000 h at 100 mA·cm −2 . Operando spectroscopic characterizations and density functional theory (DFT) calculations indicated that electron-withdrawing functional groups on chitosan-derived amorphous carbon induced interfacial electron transfer, which stabilized electron-deficient Ni 3+ sites. This pre-stabilized Ni 3+ facilitated the in-situ generation of active γ-NiOOH at low potential, while γ-NiOOH served as the catalytic phase to drive the UOR; the complementary synergy between the two significantly enhanced the overall catalytic performance. This study affords a versatile interfacial modulation protocol for designing high-performance crystalline/amorphous hybrid electrocatalysts, which may offer a promising route for sustainable energy conversion and the electrochemical treatment of urea-containing wastewater.

An interface-engineered S-scheme BiOBr/CoFe-LDH heterojunction photocatalyst was fabricated via a facile one-pot hydrothermal method to boost CIP degradation. The crystal structure, morphology, optoelectronic properties and interfacial charge transfer behavior were systematically characterized by XRD, TEM, XPS, photoelectrochemical measurements and density functional theory (DFT) calculations. The optimized 5-BOB/LDH/PMS/Vis system achieved ∼90% CIP removal within 60 min for 20 mg L −1 CIP solution, with an apparent rate constant 1.7-fold and 11.3-fold higher than those of pristine CoFe-LDH and BiOBr, respectively. The catalyst exhibited excellent practical applicability: it retained 81.5% activity after 5 consecutive cycles, maintained high degradation efficiency over a broad pH range (4–11) and showed universal degradation capability toward tetracycline, rhodamine B, acetaminophen and sulfadiazine. Mechanistic studies revealed that the constructed S-scheme heterojunction not only suppressed charge carrier recombination but also upshifted the d-band center of Fe species, enhancing PMS adsorption and accelerating the synergistic redox cycle between Co and Fe active sites. This work provides a rational design strategy for high-performance PMS-activating photocatalysts and demonstrates great potential for the advanced treatment of antibiotic-containing wastewater.

Time-dependent phosphorescence color (TDPC) materials, characterized by persistent luminescence, high quantum yield, and superior optical performance, have attracted increasing attention for information encryption applications. However, achieving high performance room-temperature phosphorescence (RTP) remains challenging, as oxygen readily quenches triplet excitons and nonradiative decay pathways arising from molecular vibrations and rotations further suppress phosphorescence. In this study, we designed and integrated three functional components: luminescent carbon dots (CDs), layered double hydroxides (LDHs), and the polymer matrix poly(vinyl alcohol) (PVA). Owing to the synergistic interplay of multiple interactions, the CDs-LDH composites exhibit pronounced TDPC behavior. The confinement within LDHs and the electrostatic interactions between LDHs and CDs effectively restrict the motion of CDs and suppress aggregation-induced quenching, thereby laying the groundwork for RTP properties. Furthermore, interfacial electrostatic repulsion and hydrogen bonding within the CDs-LDH@PVA system collaboratively generate a rigid architecture that suppresses nonradiative decay pathways of triplet excitons, thereby enhancing TDPC. Benefiting from these synergistic effects, the CDs-LDH@PVA composite demonstrates an ultralong RTP lifetime of 87.81 ms, representing a significant performance breakthrough and providing a novel strategy for the design of high-efficiency organic–inorganic TDPC materials.

Background Conventional single-layer coatings offer limited durability and lack active self-healing, making them inadequate for protecting copper in aggressive environments. A multilayer strategy combining passive barriers with responsive inhibitor release is therefore essential for enhanced corrosion resistance. Methods A hierarchical self-healing coating was constructed by combining an in-situ grown, silane-modified layered double hydroxides (LDH) film, core–shell PVDF@BTA (PB) nanofibers, and an epoxy (EP) topcoat. The LDH layer extended ion-diffusion pathways and enhanced adhesion, while the nanofibers enabled controlled BTA release upon damage. Interfacial interactions were examined using spectroscopy, SEM/EDS, XRD, FTIR, and molecular dynamics (MD) simulations. Anticorrosion and self-healing performance were evaluated by EIS, OCP, polarization testing, and BTA-release kinetics . Significant Findings The LDHA/PB/EP coating exhibited outstanding long-term corrosion resistance, achieving a high |Z| 0.01 Hz of 4.32 × 10 9 Ω·cm 2 and maintaining stability after 60 days of immersion. Upon mechanical damage, the coating restored up to 90.3% of its original corrosion resistance through synergistic formation of LDHA–BTA and Cu–BTA protective complexes. MD simulations and electrochemical tests confirmed ATES-enhanced BTA adsorption, enabling dense inhibitor films. This multilayer design affords both passive barrier protection and active self-healing, offering a promising strategy for high-performance, intelligent anticorrosion coatings for copper systems.

A novel S-scheme heterojunction N,S-NiFe-LDH/N-Bi₂MoO₆ was successfully constructed. • 5 wt% N,S-NiFe-LDH/N-Bi₂MoO₆ showed the highest activity, degrading 86.3% of TC in 100 min under visible light. • Element doping and interface engineering synergistically enhanced visible-light absorption and charge separation. • ·OH and ·O₂ − were the dominant active species responsible for TC degradation. A step-scheme (S-scheme) heterojunction photocatalyst was constructed via a hydrothermal method, consisting of N,S co-doped NiFe layered double hydroxide (N,S-NiFe-LDH) and nitrogen-doped bismuth molybdate (N-Bi₂MoO₆). The morphology, crystal structure, optical properties, elemental valence states, and charge separation/transport performance of the composite catalyst were systematically investigated using various characterization techniques, including SEM, TEM, HRTEM, XRD, UV–Vis DRS, XPS, and EIS. Its photocatalytic activity was evaluated through tetracycline (TC) degradation experiments under visible light irradiation, and the catalytic mechanism was elucidated by EPR radical detection. The results showed that the incorporation of N,S-NiFe-LDH enhanced the photocatalytic performance of the composite catalyst. Among the tested samples, the 5 wt% N,S-NiFe-LDH/N-Bi₂MoO₆ composite exhibited the highest degradation efficiency, achieving 86.3% TC removal within 100 min. The synergistic interaction between N,S-NiFe-LDH and N-Bi₂MoO₆ promoted the separation efficiency of electrons and holes, thereby significantly enhancing the photocatalytic activity.

Ga-doped zinc oxide (GZO) has attracted considerable interest for applications in electronic transport owing to its superior electrical properties. In this study, we report a low-temperature (<100°C) aqueous open-system route for the in-situ synthesis of GZO powders. The efficient substitutional doping of Ga 3+ into the ZnO lattice is achieved via a formation, in-situ transformation and dissolution–reprecipitation pathway of ε-Zn(OH) 2 or ZnGa-layered double hydroxide (ZnGa-LDH) intermediates, which simultaneously endows the products with unique flower-like or bundle-like morphologies. Chemical equilibrium calculations and time-dependent experiments reveal that the ionic species Zn(NH 3 ) 4 2+ and Ga(OH) 4 - , formed in the aqueous solution under high ammonia concentration, serve as reactive monomers that facilitate the formation and transformation of the intermediate phases. Electrical measurements combined with UV-Vis-NIR, EPR, and PL spectroscopic analyses indicate that Ga doping introduces shallow donor-type defects alongside zinc vacancy-related acceptor defects into the ZnO lattice, narrowing the optical bandgap and enhancing the electrical conductivity of the resulting powders. The GZO powder with a nominal doping ratio of 5% exhibits the lowest resistivity (Surface resistivity measured by the four-probe method is 3.43 × 10 4 Ω/□). This work provides a new pathway for the controllable preparation of functional conductive oxide powders.

To address the limited activity and durability of oxygen evolution reaction (OER) electrocatalysts, we present an integrated in situ strategy for constructing a three-dimensional Ni-Co dendritic electrode matrix coupled with a surface amorphous Ni-Co-Fe layered double hydroxide (LDH) catalytic layer. A Ni-Co dendritic matrix (NCDEM) with enhanced electrolyte accessibility and mass transport properties is first fabricated via jet electrodeposition, followed by the in situ hydrothermal growth of Ni-Co-Fe LDH nanosheets to construct a Ni-Co-Fe dendritic electrode (NCFDE). The introduction of NaBO₂ during the hydrothermal process regulates surface etching kinetics and the Fe³ ⁺ coordination environment, promoting uniform nanosheet growth and triggering the crystalline-to-amorphous transition of the LDH structure. The amorphous LDH layer increases the accessible active surface area, facilitates the formation of reconstructed NiOOH active species during OER, and enhances structural stability during prolonged electrochemical operation. The optimized B2-NCFDE exhibits outstanding OER performance in 1 M KOH, requiring an overpotential of only 215.34 mV to achieve 100 mA cm⁻², with a Tafel slope of 38.29 mV dec⁻¹ and stable operation at 500 mA cm⁻² for 2000 h. Furthermore, the B2-NCFDE||B2-NCFDE electrolyzer achieves 100 mA cm⁻² at a cell voltage of 1.822 V and demonstrates excellent durability for overall water splitting. This work provides a scalable strategy that integrates electrode architecture engineering with amorphous LDH regulation for efficient and durable hydrogen production.

The extraction and recovery of uranium play a crucial role in ensuring the sustainable supply of nuclear energy and safeguarding environmental security. The ideal uranium adsorbent should have high adsorption capacity, excellent selectivity, and good reusability. In this study, by employing the strategy of using MIL-100(Fe) as an intermediate linker, the core shell, structured of Fe3O4@NiFe-LDH, was successfully accomplished via a solvothermal method. The as-prepared Fe3O4@NiFe-LDH shows great potential in the field of uranium adsorption.On one hand, MIL-100(Fe) can act as an iron source for NiFe-LDH, making the core-shell structure more stable. It was observed that after four adsorption-desorption cycles, the adsorption efficiency of Fe3O4@NiFe-LDH could still reach 75% in the fifth cycle. By contrast, materials without the MIL-100(Fe) intermediate layer exhibited a relatively lower adsorption cycle efficiency for three cycles. On the other hand, the porous structure of metal organic framework (MOF) doubles the specific surface area of Fe3O4@NiFe-LDH compared to Fe3O4/NiFe-LDH without a MOF intermediate layer.The abundant hierarchical pore structure further enhances the performance of Fe3O4@NiFe-LDH from 615.6 mg·g−1 of Fe3O4/NiFe-LDH(8:1) to 862 mg·g−1. Additionally, in-depth studies on adsorption kinetics and adsorption thermodynamics suggest that the adsorption process is more inclined to monolayer adsorption and is dominated by chemical adsorption, which is a spontaneous endothermic process. When conducting ion competition tests on the adsorbent, it was found that the adsorbent has high adsorption selectivity for U(VI) and good regeneration ability. Therefore, the addition of the intermediate MOF improves the adsorption capacity and stability of the material, indicating that Fe3O4@NiFe-LDH has potential advantages in practical applications.

Uranium (U) contamination in natural waters poses a serious threat to both ecosystems and human health. However, the efficient adsorption and separation of U(VI) remains significantly challenging due to its extremely low concentrations and the complexity of coexisting ions. Herein, we demonstrated that MgAl-LDH/CNT composites with synergistic interfacial properties were successfully synthesized via a hydrothermal method, enabling efficient adsorption and separation of U(VI) from various natural waters while maintaining excellent chemical stability and anti-interference capacity. The evaluation of adsorption performance indicated that U(VI) adsorption by MgAl-LDH/CNT composites reached equilibrium within 10 min at pH 3, exhibiting a maximum adsorption capacity of 126.4 mg/g at 298 K. Furthermore, MgAl-LDH/CNT composites exhibited excellent resistance to coexisting ions, maintaining the adsorption efficiency over 95 % after five adsorption-desorption cycles. The adsorption mechanism studies based on FT-IR, XPS, and DFT revealed that the -OH function groups in MgAl-LDH/CNT composites were involved in U(VI) complexation with a binding energy of 3.69 eV. U(VI) was preferentially enriched on the MgAl-LDH surface and its interface with CNT, confirming the interface-dominated adsorption mechanism of MgAl-LDH/CNT composites. This work provides a promising strategy for efficient adsorption and separation of U(VI) from natural waters, while offering valuable insights into environmental remediation and sustainable nuclear resource management.

The performance of mixed matrix membranes (MMMs) depends largely on the structure and composition of incorporated nanofillers. However, it remains challenging to achieve efficient separation performance with uniform filler dispersion and strong interfacial compatibility within the polymer matrix. In this study, an ionic liquid-modified hollow microsphere of tartaric acid anion-intercalated layered double hydroxide (IL@HMS TA-LDH) was designed and embedded into a PIM-1 matrix to fabricate IL@HMS TA-LDH/PIM-1 MMMs for efficient CO 2 separation. The hollow microstructure and anion-rich interlayers of LDH provide multiple facilitated transport pathways for CO 2 significantly enhancing both permeability and selectivity. Experimental and theoretical calculation results confirm that IL modification on HMS TA-LDH not only improved the interfacial compatibility between the polymer and the filler but also enhanced CO 2 affinity and the CO 2 /N 2 selectivity. The resulting MMMs surpassed the 2019 Robeson upper bound and showed good stability. The separation efficiency of the optimal 5.0 % IL@HMS TA-LDH/PIM-1 MMMs was the best (CO 2 permeability was 8550.73 ± 367.54 Barrer, CO 2 /N 2 selectivity was 40.75 ± 1.83), outperforming most of the other reported MMMs. This work offers a new strategy for designing high-performance CO 2 capture membranes by combining hollow-structured LDH with functionalized ionic liquids.
