Rechargeable magnesium batteries (rMBs) are promising techniques suitable for large-scale energy storage systems with low-cost and high safety. However, their development is severely hindered by strong coulombic effect between bivalent Mg 2+ and cathode materials . In this work, two dimensional hierarchical nano-micro hybrids are synthesized by in-situ generating VS 4 nanosheets on carbon-coated Ti 3 C 2 MXene matrix (denoted as VS 4 @Ti 3 C 2 /C). A high-performance rMB system is built by using the hierarchical nano-micro hybrids cathode, magnesium foil anode, and 0.25 M methylpyrrolidinium chloride in 0.25 M 2PhMgCl-AlCl 3 /tetrahydrofuran as the electrolyte. The existence of V–C bond proves that VS 4 is anchored on the surface of Ti 3 C 2 via a strong chemical bond, rather than simply by adsorption. The unique hierarchical nano-micro structure improves the accessibility of the electrolyte and reduces the charge transfer resistance, leading to a high discharge capacity of 492 mA h g −1 at 50 mA g −1 , an outstanding rate performance of 129 mA h g −1 at 1000 mA g −1 , and excellent cycling performance (over 900 cycles at 500 mA g −1 ). Moreover, reversible intercalation of MgCl + into VS 4 @Ti 3 C 2 /C is revealed by investigating the evolution of the hybrids during different electrochemical states. This study will shed light on designing high-performance MXene-based cathode materials for multivalent batteries.

Catalysis is an effective means to improve the slow kinetics of hydrogen absorption and desorption, as well as the poor cycle life of the 2LiBH 4 +MgH 2 composite system. In this study, The TiVC MXene was obtained by etching TiVAlC and introduced into 2LiH + MgB 2 by ball milling. Products obtained were heated and hydrogenated to prepare the 2LiBH 4 + MgH 2 (LMBH) system, which exhibits distinguished kinetic performance and capacity retention rate. In the LMBH + 6 wt% TiVC, a 9.3 wt% hydrogen is released within 35 min at 400 °C as well as hydrogenation is completed within 30 min at 350 °C, 9 MPa. Moreover, the capacity retention rate was up to 96 % after the 15 th cycle. During the heating and hydrogenation process, the TiH and V 8 C 7 are generated in-situ as active products, and stably exist in the subsequent process to catalyze the hydrogen absorption-desorption reactions of the composite. The presence of TiH/LiH/V 8 C 7 /MgB 2 interface improves the kinetic performance of the system. Reversibility is improved by inhibiting the generation of polyborane and the aggregation during the hydrogen absorption-desorption process. The interface structure-activity relationship is first elucidated that between bimetallic MXene and 2LiBH 4 + MgH 2 composite system during hydrogen absorption-desorption processes, providing a novel viewpoint and optimization path for the modification research of 2LiBH 4 + MgH 2 composites.

Surface-enhanced Raman scattering (SERS) is a novel spectroscopic technique that enables the identification of analytes through analysis of their unique chemical signatures. Its high sensitivity, specificity, and rapid response make it a valuable tool in a range of fields, including biological detection, food safety, and environmental monitoring. However, traditional SERS nanoparticle substrates are susceptible to instability and agglomeration. In this study, Ta4C3 MXene/gold nanostar (AuNSs) hybrids were prepared as SERS substrates. By optimizing the experimental conditions of AuNSs, the optimal preparation method for the Ta4C3 MXene/AuNSs composite structure was identified. The addition of MXene to the Ta4C3 MXene/AuNSs hybrid substrates was found to enhance the sensitivity of the composite for Raman detection, as evaluated using 4-aminothiophenol (PATP) as a Raman molecule. This improvement in sensitivity is attributed to the enhanced electromagnetic properties of the hybrid substrates, which facilitate more efficient charge transfer and enhance the Raman scattering process. The limit of detection (LOD) of Ta4C3 MXene/AuNSs is 10–9 M for PATP and 10–7 M for thiram solutions. In addition, good reproducibility and spatial uniformity were obtained for the Raman signals of Ta4C3 MXene/AuNSs. Furthermore, Ta4C3 MXene/AuNSs were combined with filter paper to create paper-based SERS substrates that could be used for detection. By directly wiping the apple peel and subsequently detecting the thiram residues using Ta4C3 MXene/AuNSs, the level of detection of thiram residues on the peel surface was down to 7.8 ng/cm2.

Designing transition metal phosphides (TMPs) with remarkable performance and high stability for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) plays a significant role in the commercial application of water splitting. Bimetallic phosphide (NiCoP) exhibits favorable electrocatalytic activity; however, it still suffers from intrinsic limitations such as insufficient intrinsic activity, inferior electrical conductivity, and a tendency toward particle agglomeration. To address these issues, a CeO 2 modified NiCoP particle catalyst (referred to as CeO 2 -NiCoP/Ti 3 C 2 T x ) loaded on a few layers of Ti 3 C 2 Tx MXene was synthesized using an HCl/LiF etching and hydrothermal phosphorization method. The CeO 2 -NiCoP/Ti 3 C 2 T x catalyst exhibits significantly lower overpotentials (287 mV for OER and 147 mV for HER) to achieve a current density of 10 mA cm −2 . Moreover, the catalyst demonstrates outstanding durability, with 93.6% and 84.6% retention of its activity after 27 h of OER and 25 h of HER, respectively.The favorable performance of CeO 2 -NiCoP/Ti 3 C 2 T x in HER and OER can be attributed to several advantages. Few-layer Ti 3 C 2 T x enhances the electrical conductivity of the material, and its large specific surface area prevents particle agglomeration, thus improving the material stability.The -O/-OH functional groups on the surface of Ti 3 C 2 T x endow the material with strong hydrophilicity, which facilitates the full contact between active sites and the electrolyte and accelerates the mass transfer and charge transfer kinetics. CeO 2 effectively optimizes the adsorption energy of NiCoP toward hydrogen intermediates by regulating the microelectronic structure of NiCoP, thereby boosting the HER kinetics.

Size-controllable Cu 2 O nanocubes grow in-situ on AMXene via Oswald-ripening mechanism. • Cu 2 O induces MXene amorphization, generating edge-ligand unsaturated sites for HER. • The electron-rich Cu + boosts orbital hybridization for selective glycerol oxidation. • The catalyst requires only 1.31 V electrolyzer voltage with stability exceeding 150 h. Glycerol oxidation reaction (GOR) is a mild, sustainable pathway with great potential for producing high-value chemicals such as formic acid (FA). Integrating GOR with hydrogen evolution reaction (HER) circumvents the high energy barrier of anodic oxygen evolution in traditional water splitting. However, achieving selective C C bond cleavage in glycerol-to-FA conversion remains a major technical and scientific challenge. Here, via the Ostwald ripening mechanism, size-tunable cuprous oxide nanocubes are in-situ grown on amorphous MXene (Cu 2 O/AMXene), creating well-defined dual active sites with clear functional division: electron-rich Cu + for GOR and Ti sites for HER. The optimized Cu 2 O-0/AMXene (28 nm Cu 2 O) delivers a HER overpotential of 32 mV at 10 mA cm −2 , a GOR potential of 1.13 V at 10 mA cm −2 , and a full electrolyzer voltage of 1.31 V, while maintaining excellent catalytic efficiency after 150 h of continuous operation. Cu 2 O growth induces MXene amorphization, generating edge ligand-unsaturated Ti sites that enhance water dissociation for proton supply, while Ti 4+ promotes hydrogen spillover to transfer protons to Ti 3+ for efficient HER. Electron-rich Cu + forms asymmetric Ti-O-Cu interactions via electron donation from AMXene, enhancing orbital overlap with p orbitals of glycerol oxygen atoms for GOR. This electron-rich environment inhibits Cu + oxidation to Cu 2+ at high anodic potentials, stabilizing the active s - p hybrid configuration. This work also highlights the critical role of O-functional groups on AMXene and lattice O atoms in Cu 2 O for strengthening metal-support interactions.

V 4 C 3 T x MXene/GCE for highly sensitive detection of Cd 2+ , Pb 2+ , and Cu 2+ in water. • LODs of Cd 2+ , Pb 2+ , and Cu 2+ were 2.18 μg/L, 2.02 μg/L and 1.85 μg/L, respectively. • The electrodes possess good reproducibility, storage stability, and selectivity. Water pollution induced by heavy metal ions is growing increasingly severe and endangers human health significantly. Here, a high-performance electrochemical sensor for Cd 2+ , Pb 2+ and Cu 2+ detection in aqueous samples was fabricated by modifying V 4 C 3 T x MXene on a glass carbon electrode (GCE). V 4 C 3 T x was prepared through selective etching, and its structure and chemical compositions were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The results demonstrated that the distinctive two-dimensional lamellar architecture and multivalent vanadium of V 4 C 3 T x MXene provided an ideal platform for efficient heavy metal ion enrichment and electrochemical response. The limit of detection (LOD) was 19.4 nM for Cd 2+ , 9.7 nM for Pb 2+ , and 29.1 nM for Cu 2+ . Besides, the V 4 C 3 T x /GCE was utilized to detect Cd 2+ and Pb 2+ simultaneously, with the LODs to be 24.1 and 12.2 nM. Similarly, the V 4 C 3 T x /GCE was applied for the detection of Pb 2+ and Cu 2+ simultaneously, and the LODs were 12.6 and 34.5 nM, respectively.

Fluorosilicone rubber (FSR) has emerged as a promising matrix for actuator composites, while the trade-off between dielectric performance and mechanical robustness restricts its practical applications. Herein, we report a series of FSR/Ti 3 C 2 T x MXene composites modified with nano-sized BaTiO 3 (nBT) and micro-sized BaTiO 3 (μBT) to investigate the size-dependent effects of BaTiO 3 on composite performance. Owing to the coordination effect between MXene and BaTiO 3 , uniform dispersion of fillers was achieved, and the composites exhibited thermal stability exceeding 400°C. The FSR/MXene composite with 8 phr (parts per hundred rubber) nBT showed a tensile strength of 486 kPa, elongation at break of 194%, and elastic modulus of 356 kPa, superior to the μBT-modified composite. It also possessed a higher dielectric constant (12.85 at 10 3 Hz) and lower dielectric loss (0.00522) than μBT-modified counterparts, attributed to stronger interfacial polarization and less particle agglomeration. Notably, an actuated strain of 19.58% at 45 kV mm −1 was achieved, 35.7% higher than the μBT-modified composite. This work reveals that BaTiO 3 particle size significantly regulates the synergistic interaction between ceramic particles and conductive MXene, providing a feasible strategy for designing high-performance FSR-based composites toward soft actuator and sensor applications.

Separation membranes intended for micro/nanoplastics (MPs) removal from drinking water are still-largely constrained-by-low permeability, poor antibacterial activity, and insufficient cycling stability. In-this work, silver nanoparticles (AgNPs) were reduced in situ on graphene oxide (GO) to-form AgrG composite which were then hybridized-with MXene to fabricate AgrG-M membrane for efficient-MPs removal-from water. The AgrG-M membrane features a-large interlayer spacing, resulting in-high permeability (353.95 L m −2 h −1 bar −1 ) and a satisfactory MPs removal efficiency of over 99.9%. In addition, the incorporation of AgNPs endows the hybrid membrane with excellent broad-spectrum antibacterial activity, and the leaching concentration of silver ions in the effluent fully complies with the limits of drinking water standards, which guarantees the biosafety for practical application. Further stability evaluations confirm that the membrane maintains outstanding stability in solutions with a wide pH range of 3–11; long-term separation tests show that the MPs removal rate remains above 99.9% during 48 h of continuous operation, and the membrane permeability only declines by 10.4% after 20 consecutive filtration cycles. Under real-world conditions, the membrane also shows remarkable MPs removal performance in tap water and rainwater. In summary, the prepared AgrG-M hybrid membrane exhibits significant application potential and practical value for the advanced purification of drinking water containing MPs.

Chronic bacterial infections pose a therapeutic challenge in eliminating bacteria while suppressing inflammation. Conventional antibiotics are often limited by drug resistance and poor biofilm penetration, contributing to a global health threat of antibiotic misuse. Reactive oxygen species (ROS) modulation offers a promising alternative, yet requires precise balance: insufficient ROS compromises antibacterial efficacy, but excess exacerbates inflammation. Here, we present a bidirectional ROS-regulation strategy for programmed antibacterial and anti-inflammatory therapy using Au-edged cuprous oxide (Cu 2 O) nanocubes on MXene (Au-Cu 2 O/MXene). Under near-infrared (NIR) irradiation, this nanocomposite induces moderate ROS, eliminating >99% of planktonic bacteria and >97% of mature biofilms. After cessation of NIR irradiation, the nanocomposite itself switches to scavenge the residual excessive ROS in the inflammatory microenvironment, which alleviates oxidative stress. Our skin wound infection model further demonstrates that Au-Cu 2 O/MXene markedly reduces bacterial burden, suppresses inflammatory responses, and accelerates wound closure. Theoretical computations reveal that Au-capping weakens O 2 adsorption through weak O 2p-Au 5d orbital hybridization and hinders photogenerated electron transfer with high work function, suppressing ROS overproduction; it also lowers the free energy barrier for H 2 O/O 2 desorption, promoting ROS decomposition. This work offers an effective antibiotic-free immunomodulation strategy for programmed biofilm eradication, infected wound repair, and inflammation suppression via context-dependent ROS modulation.

BiOI/Bi 2 WO 6 /MXene composite was successfully synthesized via a solvothermal method, confirmed by XPS/XRD. • Optimal composite degraded 89.3% ranitidine and mineralized 56.0% in 2 h. • EPR analysis indicated that superoxide radicals (•O₂ − ) dominate the degradation process. Ranitidine, a widely used acid-suppressing drug, can undergo nitrosation in aquatic environments to generate N -nitrosodimethylamine (NDMA), a potent carcinogen that poses a serious threat to aquatic ecosystems. To address its persistence against natural degradation, a ternary BiOI/Bi₂WO₆/MXene composite was fabricated via a one-pot solvothermal synthesis. Heterojunction construction effectively broadened its visible-light harvesting capacity. Characterizations by SEM, TEM, XRD, and UV–Vis DRS confirmed the successful formation of the heterojunction with markedly enhanced visible-light absorption. Combined with band structure analysis and radical trapping experiments, a Z -scheme charge transfer mechanism was proposed. Visible-light photocatalytic tests showed that the optimal sample exhibits a high degradation efficiency of 89.3% for RAN, with a 47% relative enhancement compared with pristine BiOI. Radical identification revealed that superoxide radicals (·O₂ − ) were the dominant reactive species. The synergistic effect between the electron-conductive MXene and the interfacial heterojunction accelerated photogenerated carrier separation and ·O₂ − production. Moreover, the composite retained 72.35% of its degradation efficiency after three cycles, demonstrating good stability. This work provides a novel material design strategy for visible-light-driven ranitidine degradation and offers a theoretical basis for mitigating NDMA formation risks.

Polymer-based nanocomposite coatings capable of reducing abrasion and inhibiting corrosion simultaneously have great potential in marine metallic equipment. However, realizing composite coatings interfacial adaptability to external dynamic load and saltwater erosion still faces significant challenge. Herein, a marine environment self-adaptive nanocomposite coating was developed, leveraging frictional heat-driven solid-liquid phase transition of hierarchical MXene-polyethylene glycol (PEG)/fluroresin. The coating takes fluorocarbon resin (FR) as the matrix, incorporating MXene nanosheets chemically grafted with polyethylene glycol (PEG) of different molecular weights. Notably, this coating maintains exceptional lubricity across varying external loads (3N ∼ 5N), achieving a low friction coefficient of 0.047 and wear rate of 11.8×10 − 5 mm 3 /N·m. The low-friction behavior is primarily attributed to the hierarchical self-adaptive lubrication strategy: MXene deal with low-load friction, while higher loads generated friction is resolved through the phase transition capability of PEG. Theoretical calculation results also proved that frictional heat drives the directional migration of MXene-PEG towards the frictional interface, ensuring self-adaptive interface. Meanwhile, electrochemical impedance spectroscopy (EIS) measurements confirmed that the coating exhibits outstanding anti-corrosion performance. This work develops a hierarchical self-adaptive coating based on MXene interlayer sliding and PEG solid-liquid phase transition, enabling the coating to provide reliable anti-corrosion and wear-resistant for equipment under complex alternating load conditions.

Lithium−sulfur (Li−S) batteries are regarded as one of the most promising next-generation energy-storage systems owing to their ultrahigh theoretical energy density and the natural abundance of sulfur. However, their practical application is severely hindered by the intrinsically low electrical conductivity of sulfur, sluggish conversion kinetics of lithium polysulfides (LiPSs), and the shuttle effect of LiPSs. To address these challenges, we constructed a three-dimensional (3D) MXene/CNT−Co composite cathode host that integrates strong adsorption with efficient catalysis. The interconnected 3D MXene/CNT conductive framework effectively mitigates the restacking of MXene and establishes continuous electron/ion transport pathways. Meanwhile, the introduced Co provides highly active catalytic sites that markedly accelerate the reversible conversion of LiPSs, enhance chemical adsorption, and suppress polysulfide shuttling. Benefiting from the synergistic regulation of structure and catalysis, the S@MXene/CNT−Co electrode delivers promising electrochemical performance, exhibiting an initial specific capacity of 877.8 mAh g−1 at 1.0 C and retaining 381.2 mAh g−1 after 1000 cycles, corresponding to a capacity retention of 43.4 % and a capacity decay rate of 0.057 % per cycle. In addition, S@MXene/CNT−Co shows excellent rate capability, delivering 443.8 mAh g−1 at 2.0 C, which corresponds to 77.6 % of the initial capacity at 0.2 C. This work provides a viable strategy and rewarding perspective for designing high-performance MXene-based cathode materials for Li−S batteries.
