Firefighting clothing provides essential safeguards for firefighters while engaging in fire suppression and life rescue operations. However, the inability to actively detect hazardous gas and self-thermal degradation of conventional firefighting clothing induce critical safety threats to firefighters. Herein, we design a dual-mode perceptual sensor via programmable assembly of single-walled carbon nanotubes (SWCNTs) and Ti 3 C 2 T x MXene@MoS 2 nanocomposite in dual-mode triaxial structural aerogel fiber (DM-TSF) for both selective NH 3 and temperature monitoring. The DM-TSF is prepared through triaxial wet spinning, with an alternating p / n -type thermoelectric (TE) core, a signal decoupling aramid nanofibers layer, and an NH 3 sensing outer sheath. The TE core is composed of alternately interconnected p -type/SWCNT and n -type SWCNT/Polyethyleneimine, which exhibits high TE efficiency (8.44 μV K −1 for p -segment, 7.44 μV K −1 for n -segment) and wide-range (10–500 °C) temperature monitoring in DM-TSF. Furthermore, the abundant adsorption sites and high-density Schottky heterojunctions of the Ti 3 C 2 T x MXene@MoS 2 nanocomposite in the outer sheath enabled DM-TSF to exhibit an outstanding sensitivity (3.14% ppm −1 @20 ppm) and high selectivity for NH 3 . A portable wireless system based on DM-TSF was further developed and integrated into firefighting clothing for temperature and NH 3 monitoring, triggering alarms within 2 s and 28 s, respectively. This work sheds new light on the fabrication of intelligent multiplex hazard detection fibers that can respond to multi-hazard elements, thereby enhancing firefighters’ safety in complex fire scenarios.

The developments in hydrogen evolution reaction (HER) and supercapacitor technologies for electrochemical energy storage and conversion have received considerable attention. Although MoS 2 is electrochemically active for both HER and supercapacitors, limited active sites, slow ionic transport, and poor conductivity lead to its poor capacitance and electrocatalytic activity . Herein, hierarchical Ti 3 C 2 T x /MoS 2 /Ti 3 C 2 T x @CC (TMT@CC) composites were well-designed as electrodes for both HER and supercapacitors. Flexible TMT@CC electrodes with an area as large as ∼ 80 cm 2 and optimal mass-loading of 17.9 mg cm −2 were achieved. The inner layer Ti 3 C 2 T x in the composites provides ideal nucleation sites for the growth of MoS 2 arrays, and the outermost Ti 3 C 2 T x effectively anchors the vertically arrayed MoS 2 . The hierarchically vertical structure provides strong interfacial coupling and shortens ion diffusion paths, leading to high stability and fast ion/electron transport kinetics. Due to such a synergistic effect, the flexible binder-free TMT@CC electrodes exhibited high areal capacitance (5.06 F cm −2 at 5 mA cm −2 ) for supercapacitors and low overpotential (119 mV versus RHE at 10 mA cm −2 ) for HER catalyst. Furthermore, a high energy density of 0.125 mWh cm −2 at a power density of 1.5 mW cm −2 has been achieved from the TMT@CC-based symmetric supercapacitor . Our strategy can be expanded to other vertically arrayed hierarchical structures as electrode materials of efficient HER and supercapacitors.

Strategic engineering of heteroatomic doping configurations to precisely regulate the directional migration efficiency of photogenerated charge carriers has been demonstrated as a pivotal approach to overcome inherent kinetic limitations in semiconductor-based photocatalytic systems. Li/Co co-doped MoS 2 nanoflower structures (MLC2) were synthesized via a single-step hydrothermal protocol and applied for the photocatalytic degradation of chlorsulfuron in aqueous environments. Density functional theory analysis revealed that Li and Co atoms occupied Mo sites, generating electron-deficient centers that modified photogenerated electron transfer pathways. This strategic doping engineering enhanced charge separation efficiency, as evidenced by transient photocurrent response, electrochemical impedance spectroscopy, and Tafel curves. The optimized MLC2 catalyst demonstrated exceptional degradation performance, achieving 89.72 % chlorsulfuron removal within 360 min under visible light irradiation (λ ≥ 420 nm; 300 W), corresponding to quasi-first-order rate constants (k) 52.46-fold and 3.37-fold higher than those of undoped MoS 2 (k = 1.22 E −4 min −1 ) and Li-MoS 2 (k = 0.0019 min −1 ), respectively. The dominant role of photogenerated electrons, along with their generation and transfer pathways, had been experimentally validated. Furthermore, MLC2 demonstrated considerable potential in practical applications.

Osteomyelitis is considered as the most serious bone infection, which can lead to the bone destruction or fatal sepsis. Clinical treatments through frequent antibiotics administration and surgical debridement bring inevitable side effects including drug-resistance and disfigurements. It is urgent to develop an antibiotics-free and rapid strategy to treat osteomyelitis. Herein, a bifunctional sonosensitizer that consists of porphyrin-like Zn single-atom catalysts (g-ZnN 4 ) and MoS 2 quantum dots is developed, which exhibits excellent sonodynamic antibacterial efficiency and osteogenic ability. It is found that the construction of heterogeneous interfaces of g-ZnN 4 -MoS 2 fully activates the adsorbed O 2 due to the increased interface charge transfer, enhanced spin−flip, and reduced activation energy of O 2 . The generated 1 O 2 can kill methicillin-resistant Staphylococcus aureus (MRSA) with an antibacterial efficiency of 99.58% under 20 min of ultrasound (US) irradiation. The Zn single atoms immobilized in g-ZnN 4 can be released steadily in the form of Zn 2+ for 28 days within safe concentration, realizing the great osteoinductive ability of such a sonosensitizer. For the treatment of MRSA-infected osteomyelitis, the inflammation and bone loss can be significantly suppressed through sonodynamic ion therapy. This work provides another strategy for developing high efficiency sonosensitizer through ultrasound interfacial engineering.

In this study, ultrathin molybdenum disulfide (MoS 2 ) nanosheets with thickness of 1.6–8.8 nm were obtained by liquid-phase exfoliating bulk MoS 2 . Then, they were employed as cocatalyst to build ultrathin MoS 2 /g-C 3 N 4 heterojunction by self-assembly method. The degradation reaction of chlorimuron-methyl herbicide and tetracycline antibiotics under visible light was used to evaluate the photocatalytic properties of ultrathin MoS 2 /g-C 3 N 4 . The results showed that ultrathin MoS 2 /g-C 3 N 4 composite exhibit superior photocatalytic performance. The MoS 2 /g-C 3 N 4 composite with 15 wt% of ultrathin MoS 2 nanosheet exhibited the highest degradation efficiency with 90.4% for chlorimuron-ethyl and 91.7% for tetracycline in 45 min under simulated sunlight, which was 8.8 times and 13.4 times than that of bare g-C 3 N 4 , respectively. The outstanding photocatalytic activity of ultrathin MoS 2 /g-C 3 N 4 heterojunction thanks to the unique features of ultrathin MoS 2 nanosheet that it harvesting the entire visible light, increasing the contact surface area with the support and shortened the electron and ion migration length, as well as more exposed edge sulfur atoms as redox centers. The radical scavenger experiments showed that • OH and • O 2 - plays a key role in the photocatalytic degradation process. This study provides a new idea for the design of high-activity a co-catalyst, that is, ultrathin MoS 2 nanosheet has a significant influence on the photocatalytic performance of MoS 2 /g-C 3 N 4 heterostructure photocatalyst .

The effective removal of radioactive Sr 2+ and Cs + ions from wastewater is crucial for environmental remediation. Herein, a novel solar-enhanced adsorption platform based on a CoS 2 /MoS 2 /P-MXene/C composite aerogel has been developed that can efficiently remove Sr 2+ and Cs + ions. The constructed CoS 2 /MoS 2 heterointerface provides abundant active regions, while the hierarchical porous structure of the aerogel promotes the rapid transfer of ions and water molecules. In particular, the superior photothermal conversion ability of the CoS 2 /MoS 2 /P-MXene/C makes it capable of capturing solar energy for local heating effect, thereby increasing ion diffusion and accelerating mass transfer. This photothermal feature can greatly enhance the adsorption kinetics through the evaporation of the solution and the ion concentration at adsorption sites. The equilibrium of both Sr 2+ and Cs + was reached within 1 h under one-sun illumination. The measured maximum adsorption capacities were 98.7 and 150.6 mg/g for Sr 2+ and Cs + ions, respectively. In addition, it has excellent selectivity and recyclability as well as high performance in high-salinity solution. The CoS 2 /MoS 2 /P-MXene/C also shows promising potential in the fields of solar-driven seawater desalination and purification of wastewater containing dyes due to the multi-functionality. This work not only engineers an efficient adsorbent for treating nuclear wastewater, but also presents a generic design strategy for multifunctional adsorption system enhanced by external fields for environmental applications.

Transition metal sulfides are favored as anode materials for the next generation of lithium-ion batteries because of their high theoretical capacities and abundant natural resources. However, serious volume changes during charging and discharging pose great challenges to their stability. In this work, petal-like MoS2/Co9S8/C nanohybrids were synthesized via the immobilization of molybdyl acetoacetonate MoO2(acac)2 in ZIF-67 and subsequent combined vulcanization and thermolysis process. Benefiting from the homogeneous bimetallic sulfide and highly conductive carbon layer, the as-obtained MoS2/Co9S8/C nanohybrids exhibited a high initial discharge capacity of 988.3 mAh g−1 at 200 mA g−1 and a capacity retention > 99.9% after 50 cycles. Even at a high current density of 1000 mA g−1, the reversible capacity of MoS2/Co9S8/C is still as high as 754.6 mAh g−1, revealing extraordinary rate ability. This work can provide a general approach to design and synthesize other advanced bimetallic chalcogenides for boosting lithium-ion batteries storage performance.

This paper introduces a wireless passive humidity sensor based on a molybdenum disulfide (MoS 2 ) nanoflower and chitosan (CS) composite material, designed to address the limitations of traditional humidity sensors, including weak response, complex structure, and high cost, particularly in extreme humidity environments. The innovative MoS 2 /CS composite dielectric layer was developed by leveraging the high specific surface area and active sites of MoS 2 , in conjunction with the hydrophilicity and biocompatibility of CS. Experimental results demonstrate that an optimized composite material ratio (MoS 2 :CS = 1:20) yields an ultra-high sensitivity (660 kHz/%RH), faster response/recovery time (70 s/120 s), The device demonstrates a strong linear response within a humidity range of 40 %–60 %RH, evidenced by a linearity value of 0.98779. However, between the humidity range of 60 %–95 %RH, the resonant frequency exhibits a quintic relationship with humidity. In this range, the linearity R 2 value is 0.99656. and minimal hysteresis (approximately 3 %) across a broad humidity range (40 %–95 % RH). Furthermore, the chemical-physical synergistic adsorption mechanism of the composite material was elucidated using characterization methods such as FTIR, XPS, and SEM. Chemical adsorption (hydrogen bonding and coordination bonding) predominates at low humidity, while physical adsorption (swelling and interlayer hydration) is more prevalent at high humidity. The sensor offers several advantages, including low cost, long-term stability (no drift for 30 days), and environmental compatibility, thereby providing a high-performance solution for the Internet of Things and closed monitoring systems. This also expands the potential application of two-dimensional materials and biopolymers in the field of wireless sensing.

In present work, novel polyacrylamide immobilized molybdenum disulfide (MoS 2 @ [email protected] ) composites were synthesized via the mussel-inspired chemistry and surface initiated atom transfer radical polymerization (SI-ATRP). The as-prepared MoS 2 @ [email protected] composites were characterized by energy dispersive X-ray spectroscopy (EDX), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS). Characterization results provide sufficient evidences for the successful functionalization of MoS 2 with PAM. The products were used as adsorbents for removing of copper (II) ions. Results show the introduction of PAM onto MoS 2 could enhance the adsorption capacity of MoS 2 @ [email protected] towards copper (II) ions. The amount of adsorbed copper (II) ions by MoS 2 @ [email protected] composites is 2.5 times that of pristine MoS 2 . The effects of various experimental factors on the adsorption process, including contact time, initial copper (II) ion concentrations, solution pH and temperature, were also studied in this work. The batch experiments show that the adsorption of copper (II) ions onto MoS 2 @ [email protected] is dependent on time, pH and temperature. The optimum solution pH is observed at pH 7 and the increase of temperature is favorable for the adsorption of MoS 2 @ [email protected] towards copper (II). Based on the experiment data, the adsorption kinetics, isotherms and thermodynamics were also investigated. The kinetics and isotherm studies show that pseudo-second-order kinetic and Freundlich isotherm models could well fit with the adsorption data. The thermodynamic results show that the adsorption of copper (II) ions on MoS 2 @ [email protected] is a spontaneous and endothermic process. The adsorption process is mainly governed by the chemisorption involving the electrostatic interaction and/or chemical chelation between copper (II) ions and amino groups on the surface of MoS 2 @ [email protected] Taken together, it is proven that the PAM can be immobilized onto the MoS 2 nanosheets via the mussel-inspired chemistry and SI-ATRP, and it can enhance the adsorption performance of MoS 2 @ [email protected] composites, which might be used as adsorbents to remove heavy metal ions in real environment treatment.

Slurry-phase hydrocracking is one of the most advanced technologies for the conversion of inferior heavy oil to light fuel oil. In this work, MoS2 was combined with SiO2–ZrO2 mixed oxides to offer a new class of bifunctional catalysts for slurry-phase hydrocracking. In the bifunctional catalysts, SiO2–ZrO2 mixed oxides with abundant mesopores and acid sites act as cracking catalysts. They were presynthesized by a sol–gel-hydrothermal method and systematically characterized by X-ray diffraction (XRD), N2 adsorption, Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), NH3-temperature programed desorption (NH3-TPD), and in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The effect of Si/Zr molar ratios on the chemical structure, especially the acid properties of SiO2–ZrO2 mixed oxides were examined. Subsequently, a mixture of decalin–phenanthrene was selected as the model system to investigate the performance of bifunctional catalysts. It was found that the conversions of decalin and phenanthrene were significantly improved for MoS2/SiO2–ZrO2 bifunctional catalysts. Further analysis indicated that the Brønsted acid sites of SiO2–ZrO2 mixed oxides played an important role in the improvement of decalin and phenanthrene conversions.

The metallic phase MoS 2 (1T-MoS 2 ) supported metal-nanocatalyst is an appealing material system for accelerating the redox kinetics of non-aqueous Li | |O 2 batteries. However, the drawbacks associated with the surface orbital steric effect and the internal electron coupling results in a detrimental effect for the stability of 1T-MoS 2 , especially for the interface charge transfer. This makes it difficult to incorporate guest metal nanoparticles without compromising the 1 T phase support. To circumvent these issues, here we propose a p-block element (In-O) doping strategy to stabilize the 1 T phase MoS 2 by moderating the surface orbital steric effect and strengthening the internal chemical bonding, and thus for the epitaxial Ru nanocatalyst graft on the stabilized 1T-MoS 2 for Li | |O 2 batteries. The experimental and theoretical analyzes indicate that the In-O-MoS 2 @Ru enhances the O 2 dissociation and facilitates the adsorption of LiO 2 intermediates. This effect promotes the growth of weakly crystalline Li 2 O 2 films during oxygen reduction reaction, which can be more easily decomposed during the oxygen evolution reaction, thereby enhancing the bifunctional-catalytic kinetics. When employed at the positive electrode for non-aqueous Li | |O 2 batteries, In-O-MoS 2 @Ru shows an overpotential of 0.37 V and a cycling life of 284 cycles at 200 mA g −1 with a final discharge specific capacity of 1000 mAh g −1 at 25 °C.

Sodium-ion batteries (SIBs) and Sodium-ion capacitors (SICs) have great promise for large-scale energy storage. However, the mismatch of electrode kinetics and charge-storage capacity between anode and cathode materials remains a challenge. Here three-dimensional self-assembled MoS 2 /SnS 2 -reduced graphene oxide (MoS 2 /SnS 2 -RGO) anode material with fast Na-ion diffusion rate and pseudocapacitive charge storage has been successfully prepared via a facile hydrothermal method . With this particular structure, the Na-ion diffusion coefficient of MoS 2 /SnS 2 -RGO calculated by GITT achieves 5.53 × 10 −7 cm 2 s −1 during the desodiation process, which effectively improves the reaction kinetics for anode material. When tested against metal sodium in the potential window of 0.01–3.00 V, the optimized MoS 2 /SnS 2 -RGO delivers an excellent reversible capacity of 818.9 mA h g −1 at a specific current of 100 mA g −1 after 100 cycles and a superior rate capability of 555.4 mA h g −1 at 2000 mA g −1 over 500 cycles. So far, MoS 2 /SnS 2 -RGO possesses the highest reversible capacity among the reported anode materials . Furthermore, a SIC composed of optimized MoS 2 /SnS 2 -RGO anode and a CC cathode reaches a high specific energy of 113.9 W h kg −1 at specific power of 561.25 W kg −1 . Similarly, a SIB consisted of the MoS 2 /SnS 2 -RGO anode and a Na 3 V 2 (PO 4 ) 3 /C cathode displays the reversible discharge capacity of 56 mA h g −1 at the high rates of 2 C.
