LDH was in-situ embedded at the sponge skeleton surface. • Embedding LDH at a proper content resulted in smaller pore size, larger porosity, narrow pore size distribution. • The adsorption capacity of LDH epoxy sponge is as large as 8.10 mg/g. • After 15 times cycle adsorption, Li removal rate maintained as 47.87%. • The LDH embedded epoxy sponge showed excellent mechanical robustness and elasticity. Lithium-aluminum layered double hydroxide (Li-Al LDH) powders are still severely restricted in practical Li adsorption due to the unsatisfactory adsorption capacity, severe active component loss and inferior long-term cycling stability. Herein, we propose a novel Li-Al LDH-epoxy lithium adsorption sponge, which is fabricated via an in-situ embedding strategy, where active LDH components are uniformly anchored onto the skeleton surface of the sponge during the pore-forming process. The as-constructed LDH coating on the sponge skeleton presents an ultrathin filmy morphology with a thickness of only several micrometers, which not only well preserves the intrinsic elasticity of the pristine sponge matrix, but also significantly reinforces its mechanical strength. Meanwhile, the resultant hierarchical porous architecture further contributes to the prominent improvement of lithium adsorption performance. The optimized LDH sponge delivers a large specific surface area of 413.26 m 2 /g, a well-defined hierarchical pore system with dual pore sizes of 150 μm and 13.13 nm, and a high lithium adsorption capacity of 7.85 mg/g. More importantly, the composite sponge can stably withstand 50 compression-strain cycles under a high strain of 60% without obvious structural failure. This sponge-supported LDH composite porous system provides a brand-new design paradigm for developing high-performance adsorbents toward practical lithium extraction applications.

Ni/NiFeMo-LDH Schottky heterostructure was constructed by an electro-deposition method. • Accelerated charge transfer and reconstruction boost OER/HER kinetics. • Delivers 280 mV for OER and 250 mV for HER at 100 mA·cm −2 with long-term stability. Layered double hydroxides (LDHs) are promising OER catalysts but suffer from poor conductivity, slow interfacial charge transfer, and limited stability at high current densities. Here, we couple crystalline Ni-rich domains with an amorphous/poorly crystalline Ni-Fe-Mo hydroxide/oxyhydroxide-rich layered phase to form a conductive Mott-Schottky-type heterointerfacial architecture. The shift in XPS binding energy is consistent with interfacial electron coupling and possible charge redistribution. Electrochemical impedance measurements revealed a decrease in charge transfer resistance, and in situ Raman spectroscopy independently identified potential-induced reconstruction toward Ni(Fe)OOH-related active species. The resulting electrode achieves low overpotentials of 280 mV for OER and 250 mV for HER at 100 mA·cm −2 . Under near-industrial conditions (80 °C, 30% KOH), an AEM electrolyzer operates stably for 40 h with negligible decay, demonstrating its strong practical potential and providing guidance for the design of in situ catalytic electrodes via Schottky heterojunctions.

To address the challenge of balancing high energy density with long-term cycling stability in supercapacitor electrodes, this study proposes a collaborative design strategy that combines active-ion doping with conductive scaffold construction. Using a one-step hydrothermal method, redox-active Fe 3 + was introduced into the nickel-cobalt layered double hydroxide (NC-LDH) matrix and simultaneously anchored in situ on a highly conductive electrospun carbon nanofibers (CNFs) scaffold, yielding the NCF-LDH/CNF composite electrode. Within this architecture, the CNF skeleton not only effectively suppresses the aggregation of NCF-LDH nanosheets but also establishes continuous pathways for rapid electron transport. Meanwhile, Fe 3+ doping offeres additional electroactive sites and has a certain regulating effect on the electronic structure of the LDH layers. The combined benefits of these components significantly improve the electrochemical performance of the composite. Electrochemical tests demonstrate that at a Ni:Co:Fe mass ratio of 4:1:0.75, the resulting N 4 C 1 F 0.75 -LDH/CNF composite exhibits optimal performance, delivering a specific capacitance of 2457.4 F g −1 at a current density of 1 A g −1 . When configured as the positive electrode against an activated carbon (AC) negative electrode, an asymmetric supercapacitor based on this composite achieves an energy density of 56 Wh kg −1 at a power density of 800.6 W kg −1 , along with a capacitance retention of 85.1% after 8000 cycles at 3 A g −1 . The results highlight the N 4 C 1 F 0.75 -LDH/CNF composite is a promising candidate for high-energy-density and long- cycle -life energy storage devices.

This study addressed the critical need for antibiotic pollution control in industrial wastewater by successfully constructing a two-dimensional/two-dimensional NiFe-LDH/C 3 N 4 Z-type heterojunction photocatalyst with strong chemical bonding through an innovative interfacial chemical engineering strategy. Thermal activation was used to expose N active sites on the C 3 N 4 surface, and in-situ growth of NiFe-LDH nanosheets was achieved via co-precipitation. Stable Ni-N and Fe-N coordination bonds were constructed at the heterojunction interface, forming an efficient interfacial charge transport channel that significantly suppressed the recombination of photogenerated carriers. Material characterization showed that the catalyst possessed a broadened visible light response, enhanced specific surface area, and optimized charge separation efficiency. Photocatalytic experiments demonstrated excellent degradation performance for fluoroquinolone antibiotics such as norfloxacin, ciprofloxacin, and ofloxacin. Norfloxacin achieved a 90% removal rate within 120 minutes, with good cycling stability. Mechanistic studies revealed that the degradation process is primarily driven by superoxide radicals (·O 2 - ). This work not only proposed a novel method for constructing heterostructures through "surface active site design and in-situ interface bonding", but also experimentally revealed the key role of interfacial chemical bonding in regulating band structure, promoting charge separation and enhancing material stability, providing important theoretical and practical basis for the rational design of efficient and stable photocatalytic materials under the guidance of surface and interface science.

Active, stable, and low-cost alkaline oxygen evolution reaction (OER) catalyst is essential for large-scale hydrogen (H 2 ) production via electrochemical water splitting. Traditional catalyst design often relies on experience-driven, trial-and-error approaches, limits exploration efficiency. To overcome this, we present an artificial intelligence (AI)-assisted high-throughput framework combining large language models (LLMs)-based literature mining and Python-driven simulations. LLMs identifies FeNi-layered double hydroxide (FeNi-LDH) has excellent activity for OER while Python-based simulations propose a needle-like facilitate bubble detachment. In our experimental, the as-prepared FeNi-LDH exhibits good OER activity (237 mV at 10 mA cm −2 ). After growing FeNi-LDH on NiTe array, the needle-like FeNi-LDH-NiTe not only delivers enhanced activity (198 mV at 10 mA cm −2 ), but also exhibits faster bubble generation and migration, which allow it to stably work at high current density (1 A cm −2 ). The successful AI-guided catalyst design proposes a clear strategy to decouple kinetic and non-kinetic optimization for exploring excellent electrocatalyst.

The integration of inhibitor-encapsulated nanocontainers within organic coatings offers a viable approach for achieving sustained corrosion mitigation and extended protective functionality. In this study, a ZIF-8@LDH-P (ZLP) nanocontainer was developed, consisting of Ni-Co layered double hydroxide (LDH) derived from zeolitic imidazolate framework-8 (ZIF-8) precursors and incorporating trisodium phosphate (TSP) as a corrosion inhibitor. The release of phosphate ions from ZLP exhibited pH-responsive behavior, enabling triggered inhibitor release under corrosive conditions. When uniformly dispersed in the polyvinyl butyral (PVB) resin matrix and coated on Q235 carbon steel, the PVB/ZLP composite coating demonstrated an enhancement of two orders of magnitude in low-frequency impedance modulus (|Z| 0.01 Hz ) relative to pure PVB. Furthermore, the PVB/ZLP coating exhibited long-term protective capabilities, ascribed to the cooperative effect of regulated phosphate ions release for active corrosion inhibition, chloride ion entrapment by LDH interlayers, and the prolonged diffusion pathways for corrosive agents enabled by the lamellar structure of LDH. This study offers novel design strategies for ZIF-derived LDH nanocontainer-based anti-corrosion coatings with inhibitor loading.

To address environmental concerns of conventional flame retardants, MgAl-layered double hydroxide (LDH) was synthesized from hydro-magnesite. Utilizing hydrotalcite's structural memory effect, Cu was incorporated into LDH through acid activation and reconstruction. The obtained LDH was combined with ammonium polyphosphate (APP) into polyvinyl chloride (PVC). Composite thermal stability and flame retardancy were systematically evaluated. Results demonstrated that MgAlCu-LDH/APP/PVC exhibited optimal performance, with limiting oxygen index (LOI) increasing from 26.1% (pure PVC) to 31.4%, achieving UL-94 V-0 rating. Cone calorimetry tests showed 19.7% and 20.9% reductions in peak heat release rate (PHRR) and total heat release (THR), respectively. Peak smoke production rate (PSPR) and total smoke production (TSP) decreased by 27.8% and 48.9%. These enhancements originated from synergistic dilution of flammable gases by NH 3 (from APP decomposition) and CO 2 (from LDH). Additionally, APP's acidic sites and Cu's catalytic effect jointly promoted PVC dehydrochlorination and aromatization, forming a dense char layer that effectively suppressed heat and mass transfer. This acid activation–in situ replacement method provides a novel strategy for synthesizing MgAlCu-LDH and other ternary LDHs, demonstrating promising potential for improving polymer fire safety.

Spinal cord injury (SCI) induces the formation of a complex pathological microenvironment characterized by excessive reactive oxygen species (ROS) accumulation, persistent hypoxia and severe inflammatory responses, which severely impairs the processes of neural regeneration and functional recovery. To address these critical issues, we constructed a hydrogel system for the synergistic repair of SCI by integrating magnesium-manganese layered double hydroxides (MgMn-LDHs) into a ROS/pH-responsive GelMA-PBA/HA-DA hydrogel matrix. Harnessing the redox activity of Mn3+, MgMn-LDHs efficiently scavenge excess ROS and create a regenerative microenvironment favorable for neural repair. Meanwhile, Mg2+ promotes axonal elongation, myelination and the polarization of anti-inflammatory M2 macrophages by regulating key neural differentiation signaling pathways. The GelMA-PBA/HA-DA hydrogel, crosslinked via dynamic boronate ester bonds, enables the precise and controlled release of MgMn-LDHs in the acidic and highly oxidative pathological microenvironment post-SCI. In vitro experiments demonstrated that this hydrogel system could effectively support the proliferation and neurite outgrowth of PC12 cells under hypoxic and ROS-enriched conditions, inhibit the secretion of pro-inflammatory cytokines, and significantly promote vascular regeneration. In vivo studies in a mouse SCI model revealed that the hydrogel system markedly improved locomotor function, reduced the expression levels of inflammatory markers, ameliorated the inflammatory status of injured tissues, and effectively facilitated axonal regeneration and remyelination at the injury site. This MgMn-LDHs-loaded GelMA-PBA/HA-DA hydrogel system establishes a multifunctional and translatable therapeutic platform for SCI treatment, and also provides valuable insights for the research on therapeutic strategies against other neurodegenerative diseases.

Myocardial ischemia/reperfusion (I/R) injury represents a major global health concern, driven by excessive reactive oxygen species (ROS), which closely correlates with subsequent myocardial infarction and fibrosis. Combining ROS scavenging with ischemic myocardium revascularization holds therapeutic promise. However, developing multifunctional therapeutic agents that can simultaneously scavenge ROS and promote angiogenesis remains unreported. Herein, we propose MgSrCeAl-layered double hydroxide (LDH) nanosheets as a multifunctional ROS scavenger and angiogenesis promoter for efficient myocardial I/R injury treatment. MgSrCeAl-LDH nanosheets not only exhibit exceptional hydroxyl radicals (·OH) and superoxide anions (·O 2 − ) scavenging capabilities, which is 1.78 times and 1.61 times that of CeO 2 , respectively, but also respond to the ischemia-induced acidic microenvironment to release angiogenic Sr 2+ with a concentration of 32.65 ppm (pH 5.0), which is conducive to efficient angiogenesis. Specifically, the ROS levels in I/R-injured myocardium decreased to 66.2% of its original value following intervention with MgSrCeAl-LDH nanosheets, while the vascular density in the peri-ischemic myocardium increased by approximately 3.6-fold. Ultimately, the infarcted myocardial area is reduced 60.9% compared to the group without MgSrCeAl-LDH intervention. Mechanistically, MgSrCeAl-LDH nanosheets alleviate myocardial infarction and fibrosis caused by I/R injury through activating PI3K/Akt pathway and inhibiting TGF-β pathway, ultimately improving cardiac function and inhibiting ventricular remodeling.

Two-dimensional MXenes, with their accordion-like morphology and facile exfoliation into monolayers, offer an ideal platform for immobilizing electroactive materials. However, composites fabricated from MXenes through conventional methods exhibit inhomogeneous dispersion, sluggish charge redistribution, and poor interfacial coupling, limiting their potassium-ion storage performance. Herein, an interlayer-engineered CoGa-LDH/MXene heterostructure is fabricated via Peltier effect-driven rotational hydrothermal synthesis with tunable Co/Ga ratios. This approach ensures atomic-level confinement of layered double hydroxide (LDH) within MXene interlayers while strengthening interfacial coupling and ion transport kinetics. The resulting heteroarchitecture synergizes the high pseudocapacitance of CoGa-LDH and the metallic conductivity of MXene, enabling ultrafast ion/electron transport and suppressing self-aggregation. Optimized Co 1 Ga 1 -LDH/MXene delivers a remarkable specific capacitance of 1345.3 F/g and exceptional cyclability (85.13 % retention after 6000 cycles), surpassing most reported LDH-based supercapacitors. Density functional theory (DFT) calculations reveal that the heterointerface enhances K + -ion adsorption energy and modulates charge distribution, accelerating redox kinetics. When the Co 1 Ga 1 -LDH/MXene composite is assembled into an asymmetric supercapacitor (ASC), the device achieves an energy density of 77.4 Wh/kg at 1125 W/kg, with sustained performance under rigorous cycling. This work elucidates the confinement engineering of MXene-based compounds and their potassium storage mechanisms, providing critical references for high-energy-density supercapacitors in alkaline systems.

A series of novel Ce-modified MnCoAl layered double oxides (Ce/MCA LDOs) were prepared using solvothermal and impregnation methods for NH3-SCR denitration. Various characterizations, such as X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and H2temperature-programmed reduction (H2-TPR) were used to investigate their structural properties and the mechanism of ammonia selective catalytic reduction (NH3-SCR). The incorporation of Ce was found to effectively integrate into the LDO framework and enhance the catalytic activity over a wide temperature window. Moreover, the thermal stability and resistance of H2O and SO2were evaluated. In situ DRIFTS studies revealed that the reaction follows both the “Langmuir–Hinshelwood” (L–H) and “Eley–Rideal” (E–R) mechanisms. This work provides systematic insights into the design of LDO-based catalysts, demonstrating their potential for practical application in denitration.

Mesoporous g-C 3 N 4 /Zn–Ti layered double hydroxide (LDH)-laminated van der Waals heterojunction nanosheets were prepared by a facile one-step in situ hydrothermal method . Due to the strong electrostatic interactions between the positively charged Zn–Ti LDH and negatively charged g-C 3 N 4 nanocrystal , a laminated van der Waals heterostructure was successfully formed between Zn–Ti LDH and g-C 3 N 4 . The mesoporous g-C 3 N 4 /Zn–Ti LDH-laminated van der Waals heterojunction, which had a narrow bandgap of 2.41 eV extended the photoresponse to the visible light region. The obtained heterojunctions showed excellent visible-light-driven photocatalytic performance for the complete removal of ceftriaxone sodium (up to ∼97%) and a high hydrogen production rate (∼161.87 μmol h −1 g −1 ). This was mainly attributed to the formation of the laminated van der Waals heterojunctions, which favoured charge separation and the absorption of visible light, and the mesoporous structure, which provided more surface active sites. This facile strategy for preparing mesoporous g-C 3 N 4 /Zn–Ti LDH-laminated van der Waals heterojunctions offers new insights for the fabrication of high-performance van der Waals heterojunction photocatalytic materials.
