The oxygen evolution reaction (OER) hindered by its intrinsic sluggish kinetics remains a critical bottleneck in advancing water electrolysis and metal-air battery technologies. To address this challenge, herein, a Ru single-atom-anchored MoS 2 nanosheet array on carbon cloth (Ru–MoS 2 /CC) is rationally designed to regulate the local electronic structure at the atomic scale. The isolated Ru atoms induce substantial electronic reconstruction of the MoS 2 matrix, manifested by charge redistribution, work-function reduction, enhanced electronic states near the Fermi level, orbital hybridization, and optimized d -band configuration. Such synergistic electronic modulation effectively tailors the adsorption energetics of key HER/OER intermediates (H* and OOH*), leading to markedly improved bifunctional electrocatalytic activity. Consequently, the optimized Ru-MoS 2 /CC delivers low overpotentials of 230 mV at 50 mA‧ cm −2 for OER and 103 mV at 10 mA‧ cm −2 for HER in 1 M KOH. This work highlights atomic-scale electronic engineering as an effective strategy for developing high-performance MoS 2 -based bifunctional electrocatalysts and provides fundamental insights into structure–activity relationships for sustainable water electrolysis.

A three-dimensional particle electrode was established by integrating MoS 2 with nitrogen-doped Fe Mn biochar (MoS 2 /NFMB-1.0), enabling efficient electrochemical oxidation of tetracycline (TCH) in aqueous environments. Under optimized conditions, the MoS 2 /NFMB-1.0 achieved a TCH removal efficiency of 96.60%, substantially outperforming the two-dimensional electrode system. After five successive cycles, the degradation efficiency remained at 89.65%. The MoS 2 /NFMB-1.0 also promoted stronger mineralization, with a TOC removal of 74.31%, outperforming NFMB (65.21%), MoS 2 (38.43%). Reactive oxygen species (ROS) analysis revealed that the reaction was primarily driven by 1 O 2 (39.37%), accompanied by O 2 ·- (31.73%) and ·OH (28.90%). The incorporation of MoS 2 facilitated the Fe/Mn redox cycle and ensured continuous ROS generation throughout the reaction. The 3D/MoS 2 /NFMB-1.0 system maintained strong reactivity across a broad pH range from 3 to 11 and remained effective toward several representative antibiotics. Liquid chromatography-mass spectrometry (LC-MS) further clarified the transformation pathways of TCH, while ecotoxicity prediction confirmed that the toxicity of intermediates progressively declined as the reaction proceeded. These results highlight the significant potential of the MoS 2 /NFMB-1.0-based 3D particle-electrode system for future electrochemical water treatment.

An NO 2 fiber-optic sensor with integrated humidity compensation functionality was proposed. • Excellent NO 2 detection performance with a detection limit as low as 10 ppb. • SnO 2 /MoS 2 composite significantly enhances sensitivity. This study proposes an evanescent wave fiber-optic sensor based on an SMF-CLF-TCF-CLF-SMF interferometric structure and a SnO 2 /MoS 2 composite sensitive film, which responds to NO 2 concentration and environmental humidity through changes in transmitted light intensity and interference wavelength shift, respectively, exhibiting dual-parameter differential spectral response characteristics. The structure utilizes a coreless fiber for mode conversion and employs a Thin-core Fiber as the region for evanescent field excitation and sensitive material coating. SnO 2 and MoS 2 nanomaterials were synthesized via hydrothermal methods, and SnO 2 /MoS 2 composites with varying MoS 2 loading ratios were prepared using ultrasonic mixing. Under conditions of 25 ℃ and 20% RH, the SnO 2 /1.0 wt% MoS 2 sensor demonstrated optimal overall NO 2 sensing performance: achieving a sensitivity of 2.26 dB/dec over the 10–5000 ppb range—approximately 9 times higher than that of pure SnO 2 sensors—with a minimum detectable concentration of 10 ppb, response and recovery times of approximately 16 s and 12 s, respectively, and excellent long-term stability. Humidity experiments were independently conducted at 25 ℃; as relative humidity increased from 20% to 80%, the interference spectrum continuously shifted toward shorter wavelengths, reaching a maximum wavelength shift of 16.45 nm. Experimental results indicate that changes in NO 2 concentration primarily manifest as variations in transmitted light intensity, whereas humidity changes mainly result in shifts in the interference wavelength. This research provides an experimental foundation for high-sensitivity, ppb-level NO 2 fiber-optic detection at room temperature and dual-parameter sensing of both NO 2 and humidity.

The rising contamination of water resources by levofloxacin (LEV) requires advanced remediation strategies that exceed the capabilities of the conventional methods. This study reports the rational design of a novel, multi-functional cellulose-phytic acid/Fe-MoS 2 (cellulose-PA/Fe-MoS 2 ) hybrid composite for the highly efficient removal of LEV via synergistic adsorption and photocatalysis. Cellulose served as sustainable substrate and phytic acid acted as a natural cross-linker to enhance the integration and distribution of Fe-MoS 2 onto cellulose substrate. This designed architecture results in enhanced hydrophilicity, minimized MoS 2 aggregation, and a maximized density of active sites, as confirmed by comprehensive characterization (SEM, XRD, FTIR, XPS, BET, LC-MS, EPR). The prepared composite demonstrated exceptional, temperature-dependent LEV adsorption capacities of up to 210.97 mg/g (95%) within 40 min, with kinetics and isotherms best described by pseudo-second-order and Langmuir models, indicative of chemisorption. The adsorption mechanism driven by a combination of electrostatic attraction, π–π stacking, hydrogen bonding, and coordination complexation, resulting in effective removal across a broad pH range (3−10). The cellulose-PA/Fe-MoS 2 exhibited photocatalytic effect, achieving efficient degradation of levofloxacin (LEV) (98.5%) within short time (15 mins) into small molecules (CO 2 , H 2 O, NH 3 , NO 3 , F, …etc.) as confirmed with LC-MS, driven primarily by reactive species (•O 2 − , •OH, h + ). In addition, it was demonstrated good recyclability, maintaining high performance over five consecutive cycles. These findings suggest that the designed cellulose-PA/Fe-MoS 2 composite could be used as a green and sustainable multifunctional material to simultaneously remove and degrade antibiotics from water environments.

Membrane fouling, especially the composite pollution caused by inorganic scaling and biological fouling, is a key challenge in the treatment of underground karst water with high salinity and high hardness. This study reports a polyethersulfone (PES) ultrafiltration (UF) membrane modified by molybdenum disulfide-tannic acid@copper ions (MoS2-TA@Cu2+) bionanomaterial. By blending MoS2-TA@Cu2+ nanoparticles into the PES matrix, the membrane's structure and comprehensive properties were systematically controlled. Scanning electron microscopy (SEM) and static water contact angle measurements were employed to characterize the morphology and surface properties of the membranes. Characterization analysis confirmed that the hydrophilicity of the modified membrane was enhanced (the water contact angle [WCA] was reduced from 69° to 56°), and it showed high antibacterial properties (the antibacterial rate against Escherichia coli [E. coli] reached 95%). The core contribution of this study is to systematically elucidate the tunable trade-off mechanism between key membrane properties dominated by nanoparticle loading. Specifically, a loading capacity of 10 g/m2 achieved optimal anti-fouling stability, with a flux recovery rate (FRR) as high as 81.5% (40.5% higher than that of the original membrane). In contrast, a loading capacity of 15 g/m2 showed the superior permeation and separation performance, with a turbidity removal rate of 92.9% in actual karst water and a silt density index (SDI) reduction value of 5.3, fully meeting the stringent requirements of reverse osmosis pretreatment. Both static and dynamic anti-fouling experiments confirmed its excellent performance, with the CaCO3 scaling amount reduced by up to 65.2%. This study provides an effective strategy for the development of multifunctional UF membranes that can cope with complex water quality challenges by revealing the inherent trade-off between separation efficiency and anti-fouling stability. This paper provides the key theoretical basis and practical guidance for the precise design of high-performance multifunctional membranes.

Flexible and application-oriented surface-enhanced Raman spectroscopy (SERS) substrates are in high demand for trace-level molecular detection in complex environmental matrices. Herein, we report the development of a flexible hybrid SERS substrate supported on polydimethylsiloxane (PDMS), integrating phase-engineered 1T/2H-MoS2 nanoclusters decorated with Au nanoparticles (denoted as PDMS@1T/2H-MoS2@Au). Benefiting from the synergistic coupling between localized surface plasmon resonance (LSPR) of Au nanoparticles and charge-transfer-induced chemical enhancement from 1T/2H mixed-phase MoS2, the as-fabricated substrate exhibits strong and tunable SERS responses under multiwavelength excitation. Systematic SERS performance evaluations demonstrate that the substrate achieves high sensitivity with a detection limit down to 10–10 M for methylene blue (MB), excellent signal uniformity with a relative standard deviation (RSD) of 6.57%, and long-term stability with negligible signal degradation over 2 months, outperforming most flexible SERS substrates. Notably, multivariate analysis based on principal component analysis (PCA) reveals selective signal amplification toward MB in multicomponent dye systems, where the first principal component shows a strong correlation with the Raman fingerprint of MB. After spectral normalization, the PCA score plots further confirm the reliable molecular discrimination capability among multiple dye molecules. Importantly, the practical applicability of the flexible PDMS@1T/2H-MoS2@Au substrate is validated by the trace-level detection of the pesticide thiram on real apple surfaces through conformal contact, achieving a detection limit as low as 10–9 M. This work presents an application-focused sensing workflow, from the elucidation of the enhancement mechanism to real-sample analysis, highlighting the great potential of flexible MoS2–Au hybrid SERS substrates for advanced environmental and food safety molecular sensing.

Two-dimensional materials hold great promise for postsilicon electronics, but their conventional high-temperature synthesis hinders integration with back-end-of-line processes. Here, we present an enclosed chemical vapor transport (ECVT) process for growing centimeter-scale uniform and continuous monolayer MoS2 and WS2 films at temperatures as low as 280 and 350 °C, respectively. The confined geometry of the ECVT system enhances the partial pressure of active molecular species, thereby reducing the energy barriers for both atomic nucleation and lateral migration of 2D materials on the substrate. The ECVT-synthesized MoS2 nanoflakes at 350 °C exhibit a single-domain size of ∼7 μm, an ultralow defect density of 1.14 × 1013 cm–2, a room-temperature mobility of ∼20 cm2 V–1 s–1, and an on/off ratio of ∼107 of the related transistors. This work may provide a viable pathway for BEOL-compatible 2D material integration.

Xanthine (XA) and hypoxanthine (HA) are key biochemical markers of meat freshness, yet rapid, wide-range, and enzyme-free quantification in complex meat matrices remains challenging. Here we report a density functional theory (DFT)-guided Cu–MoS 2 /g-C 3 N 4 heterostructure electrochemical sensor for broad-range non-enzymatic detection of XA and HA. The heterojunction prepared via a hydrothermal and ultrasonic strategy provides an efficient charge-transport pathway and enriched catalytic interfaces. DFT calculations reveal pronounced interfacial charge redistribution and strong adsorption of XA and HA on the Cu–MoS 2 /g-C 3 N 4 surface, with adsorption energies of − 0.98 eV for XA and − 2.16 eV for HA, explaining the boosted electrooxidation response. The sensor achieves low detection limits of 0.15 μM for XA and 0.28 μM for HA and wide linear ranges from 0.913 to 1643.5 μM and from 0.918 to 1653.1 μM, respectively, and enables simultaneous quantification from 0.5 to 400 μM with excellent linearity. Good stability, reproducibility, and anti-interference capability are obtained. In real meat samples, recoveries from 90.7% to 108.3% for XA and from 91.3% to 111.4% for HA agree well with high-performance liquid chromatography, supporting rapid meat freshness evaluation.

Defect-rich heterointerfaces integrated with adjustable crystalline phases and atom vacancies as a promising strategy to boost electromagnetic wave (EMW) absorption. However, challenges remain in precisely controlling the balance between construction and the electromagnetic loss mechanism. In this study, an innovative Co-MoS2-xOx@NC core-shell fiber with multiple loss mechanisms was synthesized through an in-situ growth and carbonization process. This structure ingeniously combines ZIF-67 with a carbon fiber (CNF) conductive network to form continuous conductive pathways, providing an ideal medium for conduction loss. Simultaneously, Co ions embedded between MoS2 layers induce strong lattice distortion and abundant vacancies, forming numerous heterointerfaces between Co, MoS2, and CNF. Significant differences in electron density and charge redistribution at the interface greatly enhance interfacial polarization loss. MoS2 stacked nanosheets extend the transmission path of EMWs, dissipating electromagnetic energy by enhancing multiple reflections and scattering. Consequently, Co-MoS2-xOx@NC fibers achieve a strong EMW with a minimum reflection loss of −66.43 dB at 1.98 mm and a wide effective absorption bandwidth of 5.80 GHz at 1.87 mm. This study highlights synergistic effects of lattice vacancies and heterogeneous interfaces, offering a promising solution for constructing an advanced CNF matrix wave-absorbing material.

Monolayer transition metal dichalcogenide (TMD) alloys with tunable band gaps exhibit huge potential in nanoelectronics, optoelectronics, and photonics. The scalable production of uniform atomically thin TMD alloys is a key step for the realization of their device applications but remains a large challenge so far. Here, we report oxygen-assisted chemical vapor deposition (CVD) of uniform atomically thin MoS2(1–x)Se2x semiconductor alloys via a vertical Mo-precursor supply strategy. The growth scheme leads to the formation of highly crystalline MoS2(1–x)Se2x monolayer films within a short growth time of 8 min, which benefits from a stable and homogeneous Mo-precursor feeding environment and the synergic effect of NaBr and oxygen carrier on the growth. The high-resolution spectral characterizations and density functional theory calculations demonstrate that the chemical composition of the as-grown MoS2(1–x)Se2x monolayers can be continuously tuned from x = 0 to 1, leading to the corresponding band gap being gradually changed from 1.81 to 1.55 eV. This work provides an efficient strategy to obtain large-area uniform MoS2(1–x)Se2x monolayer alloys with tunable compositions and optical properties, which is essential for driving their applications in various functional optoelectronic devices, especially for high-performance flexible photodetectors.

The moderate working voltage and high capacity of transition metal dichalcogenides (TMDs) make them promising anode materials for aqueous calcium-ion batteries (ACIBs). However, the large radius and two charges of Ca2+ cause TMDs to exhibit poor performance in ACIBs. Therefore, effective regulation strategies are crucial for enabling the application of TMDs in ACIBs. Herein, MoS2 with expanded interlayer spacing and an enriched 1T phase (ES-1T-MoS2) is constructed by molecular engineering and reported as an anode material for ACIBs. Molecular engineering increases the capacity of MoS2 from 29.4 to 91.2 mAh g–1 and improves its rate performance from 20 to 76.1 mAh g–1 at 2.0 A g–1. ES-1T-MoS2 also shows a −20 to 50 °C wide temperature working capability. Furthermore, the capacity improvement reasons and the calcium storage mechanism of ES-1T-MoS2 are revealed through density functional theory calculations and in situ/ex situ characterizations. Finally, a “rocking-chair” aqueous calcium-ion pouch cell with a Prussian blue analogue cathode and ES-1T-MoS2 anode is assembled. The pouch cell exhibits a life of 150 cycles with over 90.8% capacity retention at 0 and 25 °C. This work demonstrates that molecular engineering is an effective strategy to improve the calcium storage performance of TMDs and promotes the advancement of ACIBs.

Using water flow energy in the environment for water treatment is a feasible solution to alleviate energy shortages and environmental pollution. This work prepared a Cu 2 O@MoS 2 /PVDF modified pipeline with superior piezoelectric properties for norfloxacin (NOR) degradation. The piezoelectric coefficient d 33 of Cu 2 O@MoS 2 /PVDF increased by 27.7 % compared with PVDF. The piezoelectric current response test demonstrated that Cu 2 O@MoS 2 /PVDF had a higher current response than PVDF. FTIR showed that the presence of Cu 2 O@MoS 2 significantly increased the piezoelectric β -phase content of PVDF. The Cu 2 O@MoS 2 /PVDF pipeline exhibited the best degradation efficiency of 99.3 % within 40 min when the flow rate reached 1.389 L min −1 . O 2 – and OH have been shown to play an important role in NOR degradation and the possible degradation mechanism and pathways of NOR were proposed. This work provides a promising method for the efficient and green treatment of organic pollutants in water by using water flow energy and has practical application significance.
