Rechargeable sodium-ion batteries (SIBs) offer significant promise for the energy market due to their environmental friendliness, low cost, and high energy density. However, challenges such as volume expansion and sluggish reaction kinetics during charging/discharging limit the widespread practical development of SIBs. Herein, a hollow flower-like heterostructure composite material, g-Co 9 S 8 /MoS 2 @NS-C, was synthesized via a glucose-assisted hydrothermal method followed by a one-step water bath process, where g stands for glucose-derived carbon acting as the carbon structure. The hollow Co 9 S 8 framework derived from ZIF-67 provides structural stability, and accommodates volume changes during redox reactions. The Co 9 S 8 /MoS 2 heterointerface establishes a built-in electric field, which can promote the fast migration of electrons/ions. In addition, doped N and S heteroatoms within the carbon matrix and conductive carbon coating layer may cooperate synergistically not only to improve total conductivity, but also to generate more active sites. Consequently, when used as the anode of sodium batteries, the composite can exhibit a capacity value of 433.4 mAh g −1 after 200 cycles at 2 A g −1 , achieving superior capacity retention. Additionally, the electrode can still offer a particular capacity of 386.6 mAh g −1 at 5 A g −1 . Remarkably, it maintains 377.0 mAh g −1 after 200 cycles even at −30 °C under 50 mA g −1 , demonstrating exceptional low-temperature stability. This research can offer a possible route to high-performance anodes for SIBs.

Mo doping optimizes the electronic structure of ReS2. MoxRe(1–x)S2/MoS2 alloy heterojunction exhibits more favorable application prospects in photodetection due to its higher electrical conductivity than ReS2/MoS2 heterojunction. However, alloy heterojunctions are difficult to prepare controllably using conventional vapor-phase chemical vapor deposition (CVD), and the heterojunction growth mechanism remains unclear. Here, a vapor–liquid–solid temperature-gradient process is proposed to grow alloy heterojunctions within predeposited molten Mo precursor droplets. The sulfuration reaction between Re diffusing into the droplet and Mo atoms facilitates the formation of alloy structures. The growth temperatures TRe and TMo in the temperature-gradient significantly affect the growth patterns and morphology evolution of the heterojunction. The MoS2 morphology in vertical alloy heterojunctions becomes triangular as the growth temperature increases. The dimension of the top MoxRe(1–x)S2 alloy is positively correlated with the Re diffusion concentration. Moreover, lateral alloy heterojunctions and single alloys are formed at lower and higher growth temperature differences between TRe and TMo, respectively. These results provide a controllable strategy for the synthesis of isotropic/anisotropic van der Waals TMDC heterojunctions.

A sensitive fluorescence and colorimetric dual-mode detection method based on Eu 3+ and Fe 3 O 4 @MoS 2 nanocomposites was constructed. In this technique, tetracycline antibiotics (TCs) chelated with Eu 3+ to form a Eu 3+ -TCs complex which emits red fluorescence at 620 nm through the antenna effect. At the same time, Eu 3+ -TCs complex enhances the peroxidase-like activity of Fe 3 O 4 @MoS 2 to catalyze the oxidation of 3,3’,5,5’-tetramethylbenzidine (TMB) that can produce a colorimetric signal. This proposed strategy has been used to detect three antibiotics including oxytetracycline (OTC), tetracycline (TC), and chlortetracycline hydrochloride (HCl-CTC). The linear ranges of the new assay for OTC, TC, and HCl-CTC were 0.1–25 μM, 0.5–25 μM, and 0.05–5 μM with the detection limits of 0.016 μM, 0.039 μM, and 0.036 μM, respectively. Meanwhile, this new method was fast and convenient which can complete the detection in 22 min. The assay has been effectively applied to TCs detection in tap water, lake water and honey with satisfactory recoveries of 90.55–109.86%. Graphical

The development of efficient and cost-effective electrocatalysts for hydrogen production is crucial for advancing a carbon-neutral circular economy. The hydrogen evolution reaction (HER) performance of MoS 2 in alkaline media is hindered by its sluggish water-dissociation kinetics and inert basal planes. Herein, we report a novel ternary heterostructure, consisting of γ-FeOOH nanosheets and smaller Ni 3 S 2 nanosheets grown on vertical 1 T/2H MoS 2 nanosheets, that exhibits enhanced HER activity. Systematic investigations suggest that the enhanced HER performance is associated with the interfacial interactions among Ni 3 S 2 , γ-FeOOH, and MoS 2 , which involve strain coupling, electronic coupling, and functional synergy. Accordingly, the Ni 3 S 2 /γ-FeOOH/MoS 2 /CC electrode requires overpotentials of only 99.6 and 176.1 mV at 10 and 100 mAcm −2 , respectively. Remarkably, it outperforms commercial Pt/C at current densities exceeding 173.2mA cm −2 and requires an overpotential of only 213.9mV at 300 mA cm −2 , while also exhibiting robust operational stability at high current densities, highlighting its promise for further exploration toward practical alkaline water electrolysis systems. This work provides a promising strategy for designing high-performance, earth-abundant MoS 2 -based HER catalysts for alkaline water electrolysis.

A series of bacterial cellulose (BC) membranes modified with viburnum-like MoS 2 were successfully synthesized via a novel biomimetic design derived from the plant morphology of 3D viburnum flowers located on 1D branches. In a typical MoS 2 /BC composite, the BC scaffolds not only achieved high dispersion of MoS 2 microflower units, but also held excellent superhydrophobic potential owing to the abundant “windows” provided by the cross-linked BC fibers. By associating the results of characterizations and the surface wettability, the relationship between the morphology and properties of MoS 2 /BC was carefully investigated. Surface clean MoS 2 /BC had excellent light-driven water evaporation rate (3.01 kg· m −2 · h −1 ) under 1 sun irradiation. Besides, the bioinspired rough surface of organosilicon (POTS) modified MoS 2 /BC membrane exhibited superhydrophobicity with a water contact angle of 159°, which helped the 3D scaffolds “stand” on the water surface like a water strider. This flexible rough surface enabled the material to possess both self-floating and self-cleaning capabilities. In addition, the synergistic effect of the viburnum-like MoS 2 and the interconnected porous network of BC endows the membrane with excellent oil-water separation efficiency (still ∼95% after 20 cycles) as well as great potential for efficient dye adsorption. Notably, the flower-like 1 T@2H-MoS 2 in BC membrane could provide efficient antibacterial abilities for S. aureus and E. coli even without light irradiation. Meanwhile, possible mechanisms for the above multifunctions of the MoS 2 /BC membrane have been discussed. This unique biomass-derived route provided an ideal platform for further design of self-floating membrane with outstanding potential for water treatments.

The application of adhesive hydrogels with phototherapy-based antibacterial properties has been extensively exploited in the repair of infected tissues. However, bacterial stress-adaptation may compromise the antibacterial efficacy of photothermal therapy. Herein, an injectable hydrogel by integrating aldehyde-functionalized hyaluronic acid modified by methacrylic anhydride (AHAMA) with recombinant human type III collagen (rhCol III)-modified molybdenum disulfide (MoS 2 ) (namely AHAMA+rhCM hydrogel) was developed. rhCol III was cross-linked with AHAMA to form a double-network hydrogel that enhanced mechanical properties, as well as acting as a structural stabilizer of MoS 2 to improve dispersion stability, ensuring photothermal conversion and effective antibacterial properties. According to an experimental study on Staphylococcus aureus ( S. aureus )-infected wound healing, AHAMA+rhCM hydrogel under near-infrared (NIR) irradiation demonstrated the best wound healing efficiency in comparison to AHAMA and AHAMA+rhCM hydrogel without NIR exposure. This can be attributed to its potent antibacterial activity, attenuated inflammatory response, promoted angiogenesis, and optimized collagen deposition patterns, which collectively contributed to accelerated tissue regeneration and wound closure. In summary, the photothermal-driven AHAMA+rhCM hydrogel represents a promising therapeutic strategy for infected wound repair, offering a dual-action solution that integrates effective antibacterial properties with enhanced tissue regeneration capabilities.

Photocatalytic hydrogen production offers a potential route for transforming solar energy into energy. A key challenge lies in developing efficient, noble-metal-free cocatalysts that can simultaneously promote charge separation and catalysis reactions. Inspired by concept of “capacitance catalysis” and the high activity of molecular catalysts for proton reduction, herein, we construct a novel composite photocatalyst by integrating a capacitive MoS 2 cocatalyst and a cobaloxime molecular catalyst onto ZnIn 2 S 4 nanosheets. In the process, MoS 2 operates as an electron reservoir to separate and store photogenerated electrons from ZnIn 2 S 4 , effectively suppressing charge recombination. Meanwhile, the Co Ⅲ molecular catalyst provides abundant active sites for proton reduction. The optimal Co Ⅲ /MoS 2 /ZnIn 2 S 4 composite achieves an exceptional activity rate of 3685 μmol·h −1 ·g −1 , which is 9.2, 4.5, and 1.9 times that of ZnIn 2 S 4 , Co Ⅲ /ZnIn 2 S 4 , and MoS 2 /ZnIn 2 S 4 , respectively. Photoelectrochemical characterizations confirms the synergistic interplay between the two cocatalysts: the larger capacitance of MoS 2 facilitates electron storage and separation, while the Co Ⅲ molecular catalyst accelerates the release and utilization of these electrons for hydrogen production. This work demonstrates a step-by-step strategy of store and then catalysis operated by dual functionally complementary cocatalysts for designing high-performance, non-precious metal photocatalytic systems.

The decreased reaction activation energy and energetic carrier transfer kinetics behavior for H 2 O overall splitting concerning with the conducive chemisorption, and oriented conversion of *H and *OH are significantly important for efficiency and separation of H 2 generation. Herein, the concerns are addressed with crystal strain engineering induced by regulating Mo S and Ce O bonding lengths of CeO 2 /MoS 2 hetero photocatalysts to boost carrier transfer behavior and synergistically activate surface sites for eminent H 2 photocatalytic evolution. Ultrafast spatiotemporal atomic scale characterizations verify that CeO 2 /MoS 2 hetero photocatalysts endow an amplified polarization field pointing from the hexagonal MoS 2 {002} to cubic-phase CeO 2 {200} with an enlarged intensity to ~2.22 times, so prolonging the lifetime of charge carrier up to ~457 % on surface sites. Also, Mo 3 d and Ce 3 d as exposed surface redox sites by extending Mo S and Ce O promote chemisorption of *H and *OH, respectively, along with activation energy of H 2 O splitting down to ~73 %. Efficiencies for solar to H 2 from 1.30 % at 25 °C to 3.53 % at 60 °C under AM 1.5G are achieved, with the release of many H 2 bubbles. Our study highlights crystal strain engineering to synergistically regulate charge transfer behavior and surface site activation for photocatalytic H 2 production efficiency and releasing.

The rational application of piezoelectric polarization properties in non-centrosymmetric heterojunctions to improve charge separation efficiency is a novel approach for enhancing their photoelectrocatalytic capabilities for environmental purification. Herein, a noval 1T-2H MoS 2 QDs/Y-NaBi(MoO 4 ) 2 multiple heterostructures with two types S-scheme heterojunctions was formed by multi-functional materials NaBi(MoO 4 ) 2 with Y 3+ ion-doping and multi-phase state (1T, 2H and 1T-2H) MoS 2 quantum dots multi-interface polarization engineering. Material characterization and DFT calculations revealed that 1T-2H MoS 2 QDs/Y-NaBi(MoO 4 ) 2 multiple heterostructures produce highly-efficient Bi-S-Mo(IV) and Mo(IV)-S-Mo(VI) charge-transfer channels induced by multi-interface polarization engineering. 1T-2H MoS 2 QDs/Y-NaBi(MoO 4 ) 2 heterostructures were developed as photoanodes using the pressed tablet stainless-steel mesh (PT-SSM) method, and demonstrated conspicuous piezoelectric-photoelectrocatalytic (PZ-PEC) efficiency (99.88% removal within 40 min) for the degradation of organic pollutant phosphodiesterase-5 inhibitor (PDE-5i) under visible light illumination, direct-current external bias and mechanical force. This work provides new insight for synergy and mechanism between piezoelectric effect and photoelectrocatalysis for environmental clean-up.

As a crucial part of artificial photosynthesis, the design of the catalyst is important essential. Among them, the interface engineering between semiconductors and the construction of surface-active sites play a vital role in generating and transporting light-excited electrons, which can ultimately accelerate water decomposition. Therefore, the MoS 2 @MoO 3 step (S)-scheme heterojunction photocatalyst was prepared by in-situ partial sulfidation. The excellent interface engineering of MoS 2 @MoO 3 nanomaterials achieves a high surface reaction rate. The in-situ vulcanization strategy gradually corrodes from the outside to the inside. The introduction of sulfur atoms can replace oxygen atoms to build a sulfur-rich surface and generate molybdenum sulfide. The amount of thioacetamide is adjusted to control vulcanization and optimizing the experimental conditions, the best hydrogen production rate is 12416.8 µmol h −1 g −1 . An in-situ irradiation XPS experiments and DFT calculations provide a deeper understanding of the S-scheme electron transport mechanism in MoS 2 @MoO 3 . MoS 2 @MoO 3 interface interaction has penetrating electron channels and a strong interface interaction force, which effectively promotes the charge transfer between interfaces. This gradual surface vulcanization strategy provides new ideas for introducing synergistic surface-active sites and optimizing interface engineering photocatalyst projects.

A novel ultrasensitive electrochemical aptasensor was proposed for quantitative detection of Cd 2+ . To this end, flower-like polyethyleneimine-functionalized molybdenum disulfide-supported gold nanoparticles (PEI-MoS 2 [email protected] NPs) were used as substrates for the modification of bare gold electrodes (AuE). PEI-MoS 2 [email protected] NPs not only possessed excellent biocompatibility and large specific surface area to enhance the cDNA loading capacity, but also possessed good conductivity to accelerate the electron transfer rate. Furthermore, the preparation of dendritic platinum-palladium nanoparticles (PtPd NPs) can effectively load Cd 2+ -aptamer. Thionine and aptamers were loaded onto PtPd NPs to construct Thi-PtPd NPs-aptamer signal probes. The signal probes were captured by the cDNA immobilized on the electrode via base-pairing rule, and the signal of Thi was detected by differential pulse voltammetry (DPV). In the presence of Cd 2+ , aptamer-cDNA unwinded, and the combination of aptamer and Cd 2+ caused the signal probes to fall off the electrode and the electrical signal decreases. Under optimal conditions, the proposed aptasensor exhibited a linear relationship between the logarithm of Cd 2+ concentration and the current response over a wide range of 1 × 10 −3 nM to 1 × 10 2 nM, with a detection limit of 2.34 × 10 −4 nM. At the same time, the aptasensor was used to detect Cd 2+ in tap water with satisfactory results. In addition, it has good reproducibility, selectivity and stability, and has broad application prospects in heavy metal analysis.

Magnetic Fe 3 S 4 /MoS 2 composites with a visible light response were prepared, and their degradation activity was tested using tetracycline hydrochloride (TCH) as a simulated pollutant. The mass ratios of Fe 3 S 4 and MoS 2 , pH change, temperature, H 2 O 2 concentration, and catalyst addition were investigated to determine the mechanism of TCH degradation. The results show that the removal rate of TCH by the Fe 3 S 4 /MoS 2 composites is much higher than that of the pure Fe 3 S 4 or MoS 2 under pH values ranging from 1.2 to 13.2. The removal rate of TCH by Fe 3 S 4 /MoS 2 was 376.37 and 5.45 times higher than that of pure Fe 3 S 4 and MoS 2 when the mass ratio of Fe 3 S 4 and MoS 2 was 1:1 at pH 7.2. The main free radicals and metal leaching changes are analyzed. The removal mechanism of TCH was proposed by the free radical scavenger test and the metal leaching test. The mechanism proposed in this paper shows that the high catalytic activity of Fe 3 S 4 /MoS 2 composite is due to the acidic microenvironment near the surface of the composite, which reduces the production of ferric hydroxide sludge.
