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.

Two-dimensional molybdenum disulfide (MoS 2 ) nanosheets are promising nanofillers for improving the properties of polymers, but low-cost, facile and green methods need to be further explored to meet the requirements for large-scale production of modified MoS 2 nanosheets. Here, we developed a new idea that is, to prepare MoS 2 @Ag by modifying the surface of MoS 2 using radiative reduction. It is noteworthy that the modified MoS 2 @Ag can effectively improve the mechanical strength of ethylene-vinyl acetate (EVA) composites. In addition, the addition of MoS 2 @Ag was able to substantially improve the flame-retardant properties of EVA, resulting in a significant reduction in the amount of heat and smoke released from its combustion. When two parts of MoS 2 @Ag were added, the peak heat release rate and total smoke release of EVA/2.0MoS 2 @Ag composites were reduced by 29.7% and 39.2%, respectively, compared with that of pure EVA. At the same time, the toxic gases (e.g., CO) produced by the combustion of EVA composites were significantly reduced, which indicates an improvement in their fire safety.

This paper introduces a novel hybrid material, MoS 2 @Ag@PA, with a core–shell structure aimed at improving the fire safety and critical properties of ethylene vinyl acetate (EVA). The incorporation of 2% of this hybrid material results in a remarkable enhancement in both thermal conductivity and tensile strength of EVA composites, increasing by 52.4% and 22.6%, respectively. Furthermore, the inclusion of 2% of this material leads to a significant reduction in the peak of heat release rate, total heat release, and total smoke production of the EVA composites by 36.2%, 28.1%, and 29.7%, respectively, compared to pure EVA. This indicates a substantial improvement in fire safety, mechanical properties, and thermal conductivity of the EVA composites. The enhanced flame retardancy of the EVA composites is primarily attributed to the synergistic effect of various substances within the hybrid material. Therefore, the design of these hybrids presents a promising approach to enhance the overall performance of EVA.

The traditional Electro-Fenton (EF) is an efficient technology for wastewater treatment but suffers from the acidic condition requirement and external catalyst addition. To overcome these challenges, a GF@MoS 2 @FeOCl cathode was fabricated using a facile method. The as-prepared GF@MoS 2 @FeOCl cathode showed excellent performance for ciprofloxacin (CIP) degradation in EF process with RuO 2 /Ti electrode as the anode. H 2 O 2 was electro-generated and activated on-site at the cathode at mild pH without adding Fe 2+ . CIP was 100% removed with 74.4% of mineralization in 90 min at pH 6. The GF@MoS 2 @FeOCl cathode exhibited good reusability after consecutive runs of degradation. The degradation intermediates were investigated, and the possible mechanism was proposed. This work demonstrated that the prepared GF@MoS 2 @FeOCl cathode is a promising candidate for contaminants treatment in an EF system.

The development of an integrated air cathode is fundamental to flexible zinc-air batteries (ZABs) for wearable electronics. Nevertheless, its sluggish kinetics and multiple complex steps in electrochemical reaction make it necessary to persue highly active and durable electrocatalysts to meet practical application requirements. A simple one-pot hydrothermal strategy is proposed to prepare a cobalt and ruthenium dual-doped MoS 2 (Co,Ru/MoS 2 ) supported by nitrogen-doped carbon foam (NCF) catalyst for use as the air cathode in flexible ZABs. The resulting catalyst features abundant catalytic active sites and an oriented structure, demonstrating excellent OER and ORR catalytic activity. The Co,Ru/MoS 2 @NCF exhibits an excellent overpotential of 1.57 V at 10 mA cm -2 in OER, half wave potential of 0.75 V in ORR, along with outstanding long-term cycling stability both in OER and ORR under alkaline environments. The flexible ZABs based on Co,Ru/MoS 2 @NCF catalyst achieved a large open-circuit voltage (1.32 V) as well as peak power density (36 mW cm -2 ), outperforming Ru/MoS 2 @NCF and Co/MoS 2 @NCF in performance. Meanwhile, the flexible ZABs maintained stability even after over 1000 charge-discharge cycles (335 h). This achievement provides new insights for the development of flexible metal-air batteries.

Developing stable, noble-free SERS substrates with high selectivity and reproducibility remains a major analytical challenge. Herein, a novel noble-free substrate of TiO 2 decorated flower-like 2H-MoS 2 (2H-MoS 2 /TiO 2 ) heterostructure was fabricated for sensitive and selective analysis of mercury ion (Hg 2+ ) in environmental water, demonstrating high potential for monitoring real water samples following standard pretreatment. The 2H-MoS 2 /TiO 2 heterostructure can be simply prepared by two-step hydrothermal method, as well as exhibiting high SERS activity with low minimum detectable concentration (1.0 μg/L) and promising enhancement factor (about 10 5 ) for Rhodamine 6G and derivatives. The good Raman enhancement attributes to multiple synergistic effect of high adsorbability of 2H-MoS 2 /TiO 2 , molecular resonance and significant charge transfer effect, which was investigated by experiments and density functional theory simulations. The indirect analytical method for Hg 2+ based on good SERS activity and specificity of R-NH 2 for Hg 2+ was established. The low limit of detection (0.16 μg/L) with linearity of 0.5 μg/L–1.0 mg/L for Hg 2+ can be obtained. The recoveries of Hg 2+ in environmental water is 82.3–106.7 % with low relative standard deviations of 2.1–6.3 %. More than just a high-performance substrate, this work provides a general design strategy for constructing stable and practical noble-free heterojunctions, significantly advancing the development of reliable SERS methodologies for on-site environmental analysis.

Dielectric materials are promising candidates for electromagnetic wave (EMW) absorption due to the significant contribution of dielectric loss to EM energy dissipation. However, dielectric materials with single component usually exhibit limited EMW absorption performance because of their impedance mismatching and insufficient EMW attenuation capability. Reasonable designs of structure and composition are required to improve their EMW absorption performance. Herein, the rGO/MoO 2 /MoS 2 (RMM) composite with MoO 2 /MoS 2 heterogeneous microspheres grown in situ on reduced graphene oxide (rGO) is prepared through intermolecular hydrogen bonding and thermal reduction. The introduction of MoO 2 /MoS 2 microspheres not only endows the composite with abundant mesopores and large specific surface area, but also facilitates the formation of heterogeneous interfaces and structural defects. By manipulating the relative component content of MoO 2 and MoS 2 , RMM achieves excellent EMW absorption. At a relatively thin thickness of 1.70 mm, the reflection loss (RL) and effective absorption bandwidth of the composite reach −74.81 dB and 4.37 GHz. Correspondingly, the specific RL (RL/t) of the composite comes to −440.06 dB/cm, which is at the forefront among other typical dielectric microwave absorbers. This work provides a universal strategy to develop high-performance dielectric-type EMW absorption materials.

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.

The design and synthesis of non-precious metal catalysts that effectively convert water into molecular hydrogen in an acidic environment is essential to reduce the energy loss in the water splitting process. Among them, molybdenum disulfide (MoS 2 ) is considered as an effective alternative to Pt-based materials due to its excellent structure properties. Here, by using metal-organic framework (MOF) as the precursor, sodium molybdate as molybdenum sources and thiourea as sulfur sources, a hollow structure of Co–MoS 2 electrocatalyst was prepared on highly conductive carbon nanowire arrays/carbon cloth (CA/CC) by hydrothermal reaction . The combination of carbon nanowire arrays and carbon cloth ensures the high conductivity, while the hollow Co–MoS 2 structure promotes the penetration of electrolytes and the release of hydrogen bubbles . The overpotential is only 296 mV when the current density was ~1500 mA/cm 2 , which shows excellent catalytic hydrogen evolution activity of the material. In addition, the three-dimensional hollow structure avoids the use of adhesives between the active material and the self-supporting material, which can improve the stability of the material and provides a new idea to design commercial electrocatalysts.

In this paper, we report the fabrication of ionic liquid (IL)-modified molybdenum disulfide (MoS 2 ) composites via a simple but effective method, that relied on Gamma-ray-initiated polymerization of polydopamine (PDA) modified MoS 2 nanosheets using IL as a monomer. The adsorptive removal of Congo red (CR) from aqueous medium by MoS 2 @PDA@IL composites was investigated. Batch experiments were carried out thoroughly to explore the effects of various experimental factors, such as contact time, containment initial concentration, and the function of pH and system temperature on the adsorption of MoS 2 @PDA@IL composites towards CR. Based on the experimental data, the adsorption kinetics, isotherms (Langmuir and Freundlich) and thermodynamics were also studied. We demonstrated that the adsorption of CR on MoS2@PDA@IL is a spontaneous and endothermic process. The amount of adsorbed CR of the MoS 2 @PDA@IL composites (Q e, max = 112.16 mg/g) is 2.77 times that of pristine MoS 2 (Q e, max = 40.54 mg/g). The above results demonstrated that PIL functionalized MoS 2 nanosheets are promising for adsorptive removal of environmental pollutants. More importantly, owing to the universal adhesion capability of polydopamine, the method might also be extended for the fabrication of other polymeric composites with different functions for various applications. Therefore, this work will attract interest from scientists in the materials, chemistry and environmental fields.

A carbon layer usually covers the outside of SnS/MoS2 nanosheets produced by a traditional C-layer cladding process, resulting in a material with a lower specific surface area and fewer active sites. Therefore, it is difficult for these as-obtained SnS and MoS2 materials to be directly employed as electrode materials. There is a great need to develop a new C-layer coating process that can effectively coat active materials and simultaneously increase the specific surface area. In this study, novel SnS@C/MoS2 nanotubes were designed and synthesized by a self-sacrificing template method (SSTM). Specifically, MoO3 nanoribbons were first coated with Sn to produce Sn-MOF, and SnS@C/MoS2 nanotubes with a particular nanosheet architecture preserved were achieved via an elegant SSTM vulcanization strategy. This SSTM preparation method not only retains the nanosheet microstructure of the surface but also leaves a thin layer of amorphous carbon on the surface, which greatly improves the conductivity and effectively improves the cycling stability. In addition to above-mentioned advantages, there is a synergistic effect between the various components of the SnS@C/MoS2 nanotubes, which has a positive effect on the electrochemical performance. When used as the anode of a lithium-ion battery (LIB), the SnS@C/MoS2 composite can maintain a specific discharge capacity of 970.9 mAh g−1 after 500 cycles at a current density of 1 A g−1, and a specific discharge capacity of 778.1 mAh g−1 even after 1000 cycles at a current density of 2 A g−1. This method provides a reference for the synthesis of other nanostructured materials.

A hierarchically 3D structured milled lamellar MoS 2 /nano-silicon@carbon hybrid with medium capacity and long-term lifespan is designed by a green and scalable approach using ball milling process and spray-drying/pyrolysis routes. The microspheres consist of low-content nano-silicon (20 wt%), milled lamellar MoS 2 sheets and porous carbon skeletons. A mixture of silicon nanoparticles and MoS 2 flakes serves as an inner core, while porous carbon pyrolyzed from petroleum pitch acts as a protective shell. The particular architecture affords robust mechanical support, abundant buffering space and enhanced electrical conductivity , thus effectively accommodating drastic volume variation during repetitive Li + intercalation/extraction. The Si/MoS 2 @C hybrid delivers a high initial discharge specific capacity of 1257.8 mA h g −1 and exhibits a reversible capacity of 767.52 mA h g −1 at a current density 100 mA g -1 after 250 cycles. Most impressively, the electrode depicts a superior long-cycling durability with a discharge capacity of 537.6 mA h g −1 even after 1200 cycles at a current density of 500 mA g -1 . Meanwhile, the hybrid also shows excellent rate performance such as 388.1 mA h g −1 even at a large current density of 3000 mA g -1 .
