Hydrogen peroxide (H 2 O 2 ), a common food disinfectant, poses health threats through residual contamination, necessitating a sensitive detection method. In this work, a molybdenum sulfide (MoS x ) film was in situ grown on carbon cloth (CC) via electrodeposition, followed by a post-annealing treatment to convert it into MoS 2 (MoS 2 /CC). The fabricated non-enzymatic H 2 O 2 electrochemical sensor demonstrated a wide linear range (1 μM–20 mM) with a detection limit of 1.1 μM. Additionally, the sensor was applied to detect H 2 O 2 in food samples, achieving recoveries of 98.02%–111.85% and RSD < 7.09%. Mechanistic investigation with computational methods revealed that the high activity of MoS 2 arises from the presence of active sites on its surface that interact with H 2 O 2 in a moderately to strongly favorable manner. This study theoretically elucidates the structure-activity relationship between the surface characteristics of MoS 2 and its adsorption behavior toward H 2 O 2 , offering a solid theoretical framework for the optimization of MoS 2 -based sensors.

Lightweight electromagnetic wave absorbing (EMA) materials with low filler loading and environmental adaptability are highly desirable for next-generation electromagnetic protection. Herein, a multilevel MoS 2 /CoNi@helical carbon nanotubes/N-doped hollow carbon foam (MCNC) was constructed for efficient EMA. Helical carbon nanotubes generated under controlled high-temperature conditions introduce chiral and tortuous conductive pathways within the 3D hollow carbon framework, promoting multiple scattering and dielectric loss. The incorporation of MoS 2 interrupts the excessively continuous conductive network, thereby improving impedance matching, while the conductivity and electronic structure differences between MoS 2 and the carbon framework enhance interfacial polarization through charge separation. Benefiting from the synergistic effects of geometric regulation and heterointerface engineering, MCNC achieves a minimum reflection loss of −51.90 dB and a maximum effective absorption bandwidth of 6.32 GHz at an ultralow filler loading of 5 wt%. In addition, MCNC exhibits a surface temperature of 139.0 °C under near-infrared irradiation and excellent corrosion resistance in simulated seawater. This work provides an effective strategy for developing low-loading and multifunctional EMA materials through multilevel structural and interfacial design.

Two-dimensional (2D) piezoelectric semiconductors, specifically molybdenum disulfide (MoS 2 ), have emerged as premier candidates for next-generation nanoscale tactile sensors due to their exceptional electron mobility, high polarization rates, and low power consumption. However, the inherent rigidity and structural brittleness of MoS 2 hinder its seamless integration into flexible, wearable platforms. Herein, we report a synergistic strategy combining mechanical ball milling and electrospinning to fabricate high-performance MoS 2 carbon nanocrystal/polyvinylidene fluoride (MoS 2 -CNCs/PVDF) nanofibrous membranes on textile substrates. By utilizing polyvinylpyrrolidone (PVP) as a macromolecular surfactant, we achieved superior filler dispersion and optimized interfacial bonding within the polymer matrix. At an optimal PVP concentration of 10%, the composite exhibits a piezoelectric coefficient ( d 33 ) of 34 pC/N—a 1.3-fold increase over pristine PVDF and delivers a peak output voltage of 2.12 V under a 0.5 N load with high linearity ( R 2 > 0.93). Furthermore, the hierarchical composite architecture yields robust mechanical properties, including a tensile strength of 19 MPa and 100% elongation at break, effectively overcoming the traditional brittleness of inorganic MoS 2 systems. Integrated into elastic textiles, the resulting sensor enables high-fidelity real-time monitoring of physiological signals, including radial pulse, respiratory rhythms, and joint kinematics. This work provides a scalable pathway for health diagnostics and human-machine interaction.

MoS 2 and LDH were successfully integrated into a two-dimensional/two-dimensional (2D/2D) structure. • PMA with electron-capturing capability was successfully intercalated into the two-dimensional nanosheet layers. • 10% LDH-PMA/MoS 2 shows superior light harvesting capacity, 6.45-fold higher than ZnAl-LDH. Addressing urgent environmental remediation and sustainable energy needs, this study enhances photocatalytic H 2 evolution via rational design of an efficient composite catalyst. In-situ synthesis controllably grew MoS 2 onto LDH-PMA surface, constructing ZnAl-PMA/MoS 2 photocatalytic system. Photocatalytic tests show 10% MoS 2 -loaded composite exhibits optimal light harvesting, achieving 4498.59 μmol g −1 h −1 H 2 evolution, 6.45 times pristine ZnAl-LDH and 3.1 times LDH-PMA, and retaining 3890 μmol g −1 h −1 after six cycles (24 h total), confirming excellent stability. This enhanced performance arises from 2D/2D heterostructure and intercalated PMA's electron trapping capability, facilitating photogenerated carrier separation, suppressing recombination, and boosting.

Qualitative and semi-quantitative detection and identification of multiple targets is of great importance in complex sample analysis, while surface-enhanced Raman scattering (SERS) could be an efficient strategy. Here, to efficiently promote the enhancement effect, Ni doping and Au nanoparticles (AuNPs) surface modification were adopted to develop a MoS 2 SERS substrate composed of intercrossed nanoflowers, named AuNPs@Ni-MoS 2 , which exhibits high SERS enhancement towards the Raman reporter (4-mercaptobenzoic acid, 4-MBA) with an enhancement factor (EF) of 10 8 . In complex matrices of different mushrooms, this substrate can also sensitively detect α -amanitin and β -amanitin with a limit of detection (LOD) of 10 −8 M for both, which laid a solid foundation for the accurate discrimination via the following machine learning-based approach. Meanwhile, based on the AuNPs@Ni-MoS 2 substrate, sensitive and specific detection of Hg 2+ was attributed to the formation of an Au-Hg alloy, which could greatly lower the catalytic potential required for the oxidation of the colorless chromogenic agent (3,3’,5,5’-tetramethylbenzidine, TMB) to a yellow oxidized TMB (TMB 2+ ). This study not only provides a reference model for improving charge transfer efficiency in SERS system but also offers technical support for rapid screening multiple analytes in complex samples.

Efficient decontamination of toxic mercury from water remains a critical challenge. MoS 2 nanoadsorbents exhibit significant advantages for mercury capture due to the strong soft-soft interactions between Hg(II) and sulfur. However, conventional MoS 2 nanosheets or MoS 2 -based nanocomposites are often hindered by practical limitations, including difficulty in separation and recovery, pore blockage, nanoparticle leaching, and high pressure drop in flow-through systems. Herein, we report a millimeter-sized nanocomposite (MoS 2 @PDA@CER) fabricated by coating MoS 2 nanosheets onto a cation exchange resin via a polydopamine (PDA) adhesive layer. The millimeter-scale architecture enables easy separation and superior hydraulics for flow-through operation. MoS 2 @PDA@CER exhibits broad pH applicability (1–8), ultra-high adsorption capacity (1168.18 mg/g at pH 5), rapid adsorption kinetics (equilibrium within 1 h), and exceptional selectivity toward Hg(II). These outstanding properties are attributed to the synergy between the unique millimeter-sized structure of the resin support and the strong affinity of MoS 2 for Hg(II). Furthermore, the nanocomposite demonstrates deep purification capability, effectively treating various trace mercury-contaminated waters to meet drinking water standards. It also shows excellent reusability, with no significant loss in adsorption capacity after 10 cycles. In fixed-bed column tests, MoS 2 @PDA@CER successfully treated ∼3000 BV of Hg(II)-spiked wastewater, with effluent complying with the Chinese integrated wastewater discharge standard (50 μg/L); notably, the first 900 BV even met the drinking water standard (1 μg/L). All the results indicate that MoS 2 @PDA@CER is a scalable and efficient adsorbent for the remediation of mercury-contaminated wastewater.

Piezoelectric photocatalysis is emerging as a promising approach for green environmental protection. Herein, a molybdenum disulfide/graphitic carbon nitride S-scheme heterojunction catalyst achieved a Rhodamine B degradation rate exceeding 99 % within 30 min under the synergistic effects of light and ultrasound, along with a hydrogen (H 2 ) production rate of 16.2 mmol g −1 h −1 . The synergy of ultrasound and light improved catalytic efficiency by approximately 45 % compared with light alone. Experimental characterizations, including Kelvin probe force microscopy, in situ X-ray photoelectron spectroscopy, and density functional theory calculations, confirmed the presence of dual built-in electric fields arising from band alignment and strain-induced polarization. These fields facilitated efficient electron–hole separation, thereby greatly enhancing the overall piezoelectric photocatalytic performance and resulting in efficient use of mechanical and solar energy for H 2 production and pollutant decomposition.

A facile one-step hydrothermal method was used to obtain MoS 2 /CuS composite catalyst, which was analyzed using multiple characterization techniques, such as XRD, SEM, TEM, SAD, FT-IR and XPS. As-prepared MoS 2 /CuS showed an enhanced peroxydisulfate (PDS) activation performance for tetracycline (TC) elimination compared with MoS 2 and CuS in a batch reactor. The incorporation of MoS 2 and CuS possess more active sites and low-valent S substances to facilitate the circulation of Mo 6+ /Mo 4+ and Cu 2+ /Cu + , thus promoting PDS activation and TC degradation. Mechanistic studies demonstrated that the free radical (SO 4 •− , ∙ OH and O 2 •− ) and non-free radical ( 1 O 2 ) oxidation pathways collectively led to TC degradation in MoS 2 /CuS-PDS system, and 1 O 2 played a primary role. The impact of important operating factors on TC elimination, the pathways of TC degradation and the toxicity of degradation intermediates were investigated. To facilitate the practical application of MoS 2 /CuS catalyst, it was uniformly loaded onto polyurethane (PU) sponge with a rich pore structure. As-obtained MoS 2 /CuS@PU catalytic sponge activating PDS could efficiently remove TC from the different water matrices in a continuous flow reactor; moreover, MoS 2 /CuS@PU can maintain a high level of stability after 20 h of continuous operation.

The alkaline hydrogen evolution reaction (HER) is an extremely important reaction in energy conversion and electrolytic industries. Pristine MoS2 exhibits poor alkaline HER activity due to weak water adsorption and dissociation. Precisely manipulating active water dissociation components to form a functional interface with MoS2 would be an effective strategy. Herein, in-plane intergrowth CoS2/MoS2 ultrathin nanosheets have been achieved via a one-step pyrolytic sulfurization of a small-sized Co/Mo-MOF precursor. The in-plane intergrowth structure produced abundant interfaces and modulated the interfacial electronic structure, demonstrating an accelerated water dissociation process. Ultralow overpotentials at both onset (16 mV) and 10 mA cm−2 (75 mV) have been obtained, which surpass those of most top-rated MoS2-based materials and are even proximate to those of commercial Pt/C (0 mV at onset and 60 mV at 10 mA cm−2, respectively). Under a large current density of 400 mA cm−2, the intergrowth nanosheet exhibited long-term stability, showing potential for applications in alkaline water splitting devices.

Flower-like intercalated MoS 2 nanomaterials have been successfully synthesized via a microemulsionmediated hydrothermal (MMH) method, and characterized by X-ray diffraction, Raman spectroscopy, element analysis, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and Fourier transform infrared spectroscopy in detail. Their catalytic performance for anthracene hydrogenation was evaluated using a slurry-bed batch reactor with an initial hydrogen pressure of 80 bar at 350 °C for 4 h. The intercalated MoS 2 nanoflowers synthesized from Na 2 MoO 4 (MoS 2 -S) and H 2 MoO 4 (MoS 2 -A) as molybdenum precursors have diameters of about 150 and 50 nm, respectively. MoS 2 nanosheets on MoS 2 -S and MoS 2 -A possess stacking layer numbers of 5–10 and 2–5, and slab lengths of about 15 and 10 nm, respectively. The interlayer distances of MoS 2 -S and MoS 2 -A are both enlarged from 0.62 nm to about 0.95 nm due to the intercalation of NH4 + and surfactant molecules. The MoS 2 nanoflowers have high catalytic activities for anthracene hydrogenation. The selectivity for octahydroanthracene, a deeply hydrogenated product, over MoS 2 -A is 89.8%, which is 31.0 times higher than that over commercial bulk MoS 2 . Fully hydrogenated product (perhydroanthracene) was also detected over MoS 2 nanoflowers with a selectivity of 3.7%. The enhanced hydrogenation activities of MoS 2 nanoflowers can be ascribed to the high exposure of catalytic active sites, resulting from the smaller particle size, fewer stacking layer, shorter slab length and enlarged interlayer distance of MoS 2 nanoflowers compared with commercial bulk MoS 2 . In addition, a possible growth mechanism of MoS 2 nanoflowers synthesized via the MMH method was proposed.

Dodecahedral gold nanocrystals (AuNCs) were synthesized by using a 1-(10-bromodecyl)-3-methylimidazolium bromide ionic liquid as functional monomer and protectant. AuNCs were self-assembled onto molybdenum disulfite (MoS 2 ) nanosheets to fabricate AuNCs/MoS 2 nanocomposite, which was drop-coated onto a glassy carbon electrode surface to generate an interface for transthyretin (TTR) immobilizing. With a similar chemical structure to thyroxine, tetrabromobisphenol A (TBBPA) was specifically recognized by transthyretin and the TTR/AuNCs/MoS 2 /GCE provides a sensing platform for TBBPA. Its sensing performance towards TBBPA was found significantly improved by the integration of AuNCs onto MoS 2 nanosheets. Three conditions for assay development, such as incubation time, incubation temperature, and pH value, were investigated and found the optimum conditions were 200 s, 35 °C, and pH 7.0 respectively. Under these conditions, the ratio [ R i = ( i 0 − i )/ i 0 ] between the photocurrent variation (△ i = i 0 − i ) and the original photocurrent ( i 0 ) is linearly related to the logarithm of TBBPA concentration ( c TBBPA ) from 0.1 nM to 1.0 μM. The linear relationship can be described by the following equation: R i = 0.09092 log c TBBPA (M) + 0.8976 (R = 0.993). The detection limit is calculated to be 0.045 nM (S/N = 3). The photoelectrochemical immunosensor was used to accurately determine TBBPA concentration in South-Lake spiked water samples.

Creating rich vacancies and designing distinct micro-morphology are considered as effective strategies for boosting the electrochemical performances of sodium ion battery (SIB) electrode materials . In this paper, a variety of MoS 2 nanostructures with different sulfur vacancies concentration and morphologies are successfully constructed by a hydrothermal method combined with various-temperature calcination treatment in a Ar/H 2 mixed atmosphere. Employed as a free-standing anode for SIBs, the flower-like MoS 2-x microspheres assembled by the intertwined nanosheet arrays (MoS 2-x -800) delivers highest specific capacity of 525.3 mAh g −1 and rate capability, as well as extraordinarily stable cycle life with almost no loss of capacity after 420 cycles. The favorable sodium storage properties are mainly ascribed to the cooperated effects of superior intrinsic conductivity and richer active sites generated by sulfur vacancies , and numerous interspace achieved by the intersection of neighbouring nanosheets. Meanwhile, through ex situ analyses, the reversible charge/discharge mechanism of the obtained MoS 2-x -800 is revealed reasonably. This work not only brings new insights into the design of high-performance electrode materials for SIBs, but also makes a great step forward in the practical applications of transition metal sulfides in energy storage systems.
