Electronic-interface-confinement synergy enables full CO 2 -to-CH 4 conversion. • Achieves 65.4% CH 4 FE and 100 h stability with non-Cu catalyst, a new benchmark. • Nanoconfinement steers CO 2 -to-CH 4 by stabilizing intermediates and lowering HCOOH→HCO→H 2 CO* barrier. • S-vacancies and FeCo/Mo-edge electronic synergy boost activity and selectivity. • Topological transformation constructs tunable multi-shelled confinement nanoreactors. The electrochemical CO 2 reduction reaction (CO 2 RR) still faces critical challenges in achieving rapid product conversion and precise selectivity control due to kinetic limitations and thermodynamic competition. To overcome these limitations, this study develops a hierarchical hollow multi-shell FeCo@MoS 2 catalyst that integrates electronic modulation with nanoconfinement, thereby achieving kinetic enhancement and directional steering of methane production. This enhanced performance stems from two factors: sulfur vacancy-rich monolayer MoS 2 that enhances carrier mobility, and the synergistic effect of strong Mo-edge/FeCo coupling combined with nanoscale confinement for site stabilization. The optimized FeCo@MoS 2 -p30 (with pore size ≈30 nm) delivers a high methane Faradaic efficiency of 65.4% with 80 mA cm −2 at −1.0 V vs. RHE and exceptional operational stability for over 100 h. The computational results reveal that FeCo@MoS 2 -p30 promotes efficient methane production by steering the reaction pathway through a sequence of key intermediates. The nanoconfinement effect selectively stabilizes the adsorption of HCOO*, HCOOH*, HCO*, and H 2 CO* (favoring the HCOO* pathway over COOH), thereby redirecting the selectivity toward CH 4 . This is achieved by substantially reducing the energy barrier for the rate-determining HCOOH* → HCO* hydrogenation steps. Download: Download high-res image (167KB) Download: Download full-size image

A novel coaxial wet spinning strategy is reported to fabricate shape stabilized phase change aerogel fibers (C f PCF). • The fibers feature hierarchically porous flower-like PUPCM clusters engineered by CNC-directed hydrogen bonding. • The C f PCF exhibits a high phase change enthalpy (115.6 J/g), ultralow thermal conductivity (0.076 W·m −1 ·K −1 ). • The C f PCF fabrics enable outstanding infrared stealth (Infrared detection temperature decreased by 51 °C). The escalating demand for advanced fibrous materials integrating dynamic thermal management and infrared stealth has spurred continuing innovation. Traditional porous phase change fibers (PCFs) suffer from two critical deficiencies: solid-liquid phase change materials (SLPCMs) leakage and gas-solid interface degradation. Herein, we present a novel coaxial wet spinning strategy to fabricate porous shape stabilized phase change fibers (C f PCFs). The aerogel core is prepared via cellulose nanocrystals (CNCs)-directed crystallization of polyurethane-based shape stabilized PCMs (PUPCMs) that were synthesized through crosslinking polyethylene glycol with hexamethylene diisocyanate, inherently eliminating liquid leakage. Thanks to strong intermolecular hydrogen bonding interactions between CNCs and PUPCMs, in-situ crystallization and assembly of PUPCMs proceed on CNC-directed three-dimensional scaffolds via ice templating, generating flower-like crystal clusters with hierarchical porosity. This unique structure offers dual benefits: 1) Robust anchoring of shape stabilized PUPCM to prevent leakage; 2) Excellent properties of high phase change enthalpy (115.6 J/g) and porosity (69.35%), ultralow thermal conductivity (0.076 W·m −1 ·K −1 ), and superior thermal stability (91.35% enthalpy retention after 600 cycles). The as-woven C f PCF fabric demonstrates exceptional thermal buffering performance, achieving a temperature lag of up to 750 s at 80 °C. This effect stabilizes the temperature through phase-change endothermy and reduces infrared-detected temperatures by 51 °C. This work presents a new pathway for developing next-generation intelligent fibrous materials with integrated functionality.

Reducing soluble U(VI) to insoluble U(IV) is an efficient uranium extraction strategy. However, the two axial oxygen atoms in uranyl (UO 2 2 + ) create a kinetic barrier to electron transfer, hindering U(VI) reduction. Here, we present an innovative strategy that leverages the hydrogen evolution reaction (HER) to generate a localized alkaline microenvironment at the catalyst surface; OH⁻ accumulation rapidly precipitates UO 2 2 ⁺ as insoluble UO 2 (OH) 2 , enabling efficient uranium extraction from water. In this process, the S-rich hollow MoS 2+x with high HER activity, which was derived from the Mo-MOF grown on carbon felt (CF), was used as the cathode (MoS 2+x /CF) in a photovoltaic-driven electrocatalytic system. The anode consists of a TiO 2 nanorod array on FTO glass, coupled with a rear-mounted silicon solar cell. Due to the localized alkaline microenvironment formed by the HER on the MoS 2+x /CF cathode surface, this electrocatalytic system achieves 99.8% uranium removal from uranium-containing wastewater within 30 min of illumination. Density functional theory (DFT) calculations and experimental results confirm that unsaturated edge S atoms in MoS 2+x significantly enhance HER activity. Additionally, the electron transfer between uranium and edge S enhances uranium adsorption and promotes its interfacial reaction with OH*. This work opens new perspectives for uranium extraction from aqueous solutions.

In-situ 1 T/2H MoS 2 heterointerfaces synergistically combine 2H light-harvesting with 1 T conductivity for enhanced charge separation. • Optimized MoS 2 features expanded interlayer spacing and abundant active sites, accelerating Zn 2+ diffusion and redox kinetics. • The PRZIB delivers 340 mAh g −1 under illumination (vs. 237 mAh g −1 in dark) and achieves 1.2% photoconversion efficiency. • Photo-recharging couples Zn 2+ extraction with photoelectron-driven Zn deposition, while flexible devices demonstrate stable power output for LEDs. Photo-rechargeable Zn-ion batteries (PRZIBs) are constrained by photocathodes lacking efficient light harvesting, fast transport, and reversible Zn 2+ storage. Herein, we develop a temperature-controlled hydrothermal strategy to construct in-situ 1 T/2H MoS 2 photocathodes with tunable interlayer spacing and defect density. The optimized sample synthesized at 140 °C exhibits enlarged interlayer spacing, abundant active sites and an intimate 1 T/2H phase interface, which accelerate Zn 2+ diffusion and redox kinetics. Moreover, the semiconducting 2H domains absorb light while metallic 1 T domains extract photogenerated electrons, enabling synergistic charge separation. Consequently, the PRZIB achieves a photoconversion efficiency of 1.2% and a discharge capacity of 340 mAh g −1 under illumination, versus 237 mAh g −1 in the dark at 0.1 A g −1 . Mechanistically, quasi-in-situ XRD reveals that photo-recharging couples Zn 2+ extraction with photoelectron-driven Zn deposition, while discharge reverses via intercalation/stripping, as confirmed by reversible (002) reflections. Additionally, flexible devices demonstrate stable power output, driving a biomimetic bird and an LED. Overall, this work highlights heterophase junction engineering as a promising route for integrated photo-rechargeable systems.

Silicone rubber is widely recognized for its hydrophobic and mechanical properties, making it a suitable material for high-voltage insulation. This study investigates a novel approach to improving these properties by incorporating two-dimensional (2D) nanomaterials into liquid silicone rubber (LSR). Particularly, exfoliated tungsten disulfide (WS 2 ) and molybdenum disulfide (MoS 2 ) nanosheets are implemented and contrasted with their nanoparticle counterparts. To improve dispersion and interfacial bonding, all fillers were surface-functionalized using (3-aminopropyl) triethoxysilane (APTES). The results demonstrate that the incorporation of 2D nanosheets leads to substantial enhancement in hydrophobicity, mechanical strength, and electrical insulation. The composites achieved the highest hydrophobicity classification (HC1) according to the IEC TS 62073 standard, with a maximum contact angle of 139.9°, a 32% improvement over nanoparticles and unfilled samples. Mechanical tests according to ISO 37 showed increases of up to 68% in tensile strength and 72% in elongation at break. Furthermore, electrical insulation tests demonstrated that breakdown voltage improved by 17.9% and flashover voltage by 17.3% for nanosheet-filled samples. The results emphasize the efficacy of APTES-functionalized 2D nanosheet materials in the advancement of silicone rubber insulators for outdoor high-voltage applications, leading to a substantial enhancement in their performance and longevity.

Layered transition metal dichalcogenides (TMDs) have gained considerable attention as promising cathodes for aqueous zinc-ion batteries (AZIBs) because of their tunable interlayer architecture and rich active sites for Zn2+storage. However, unmodified TMDs face significant challenges, including limited redox activity, sluggish kinetics, and insufficient structural stability during cycling. These limitations are primarily attributed to their narrow interlayer spacing, strong electrostatic interactions, the large ionic hydration radius, and their high binding energy of Zn2+ions. To address these restrictions, an in situ organic polyaniline (PANI) intercalation strategy is proposed to construct molybdenum disulfide (MoS2)-based cathodes with extended layer spacing, thereby improving the zinc storage capabilities. The intercalation of PANI effectively enhances interplanar spacing of MoS2from 0.63 nm to 0.98 nm, significantly facilitating rapid Zn2+diffusion. Additionally, the π-conjugated electron structure introduced by PANI effectively shields the electrostatic interaction between Zn2+ions and the MoS2host, thereby promoting Zn2+diffusion kinetics. Furthermore, PANI also serves as a structural stabilizer, maintaining the integrity of the MoS2layers during Zn-ion insertion/extraction processes. Furthermore, the conductive conjugated PANI boosts the ionic and electronic conductivity of the electrodes. As expected, the PANI–MoS2electrodes exhibit exceptional electrochemical performance, delivering a high specific capacity of 150.1 mA h g−1at 0.1 A g−1and retaining 113.3 mA h g−1at 1 A g−1, with high capacity retention of 81.2% after 500 cycles. Ex situ characterization techniques confirm the efficient and reversible intercalation/deintercalation of Zn2+ions within the PANI–MoS2layers. This work supplies a rational interlayer engineering strategy to optimize the electrochemical performance of MoS2-based electrodes. By addressing the structural and kinetic limitations of TMDs, this approach offers new insights into the development of high-performance AZIBs for energy storage applications.

To overcome the limitations of high energy consumption and low selectivity in conventional antibiotic treatment methods, this study developed a sodium percarbonate (SPC)-activated piezoelectric-photocatalytic system using a nitrogen-doped carbon quantum dot/molybdenum disulfide (N-CQDs/MoS₂) composite to degrade oxytetracycline (OTC). The catalyst was synthesized via a hydrothermal method and characterized by X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), piezoresponse force microscopy (PFM), and electrochemical analysis. Results showed that nitrogen-doped carbon quantum dots significantly enhanced the piezoelectric and photocatalytic performance of MoS₂. Reaction conditions were optimized using response surface methodology (RSM), determining the optimal parameters as OTC concentration of 10.68 mg/L, catalyst dosage of 0.46 g/L, and SPC dosage of 0.21 g/L. Under these conditions, a degradation efficiency of 99.52% was achieved within 25 minutes, closely matching the experimental result of 99.18%. The degradation kinetics followed a quasi-first-order model (k = 0.0752 min⁻¹), confirming the model’s reliability. Radical scavenging experiments and electron paramagnetic resonance (EPR) analysis identified h⁺, •OH, and O₂•⁻ as the main reactive species. Ecotoxicity assessment showed low toxicity of the degradation products, indicating good environmental safety. The catalyst maintained a high degradation efficiency of 96% after five cycles, demonstrating excellent stability and reusability.

To enhance the utilization rate of hydrogen peroxide (H 2 O 2 ) at neutral pH for degrading refractory organic pollutants in aqueous solutions, a novel FeOF/MoS 2 catalyst was synthesized hydrothermally. The as-prepared catalyst was systematically characterized using XRD, FT-IR, Raman spectroscopy, XPS, TEM, and BET. Its performance was evaluated in a heterogeneous H 2 O 2 activation system using p -nitrophenol ( p -NP) as a model pollutant. Under neutral conditions, p -NP in aqueous solution was completely removed within 15 min in the FeOF/MoS 2 /H 2 O 2 system, demonstrating the outstanding catalytic activity of FeOF/MoS 2 in activating H 2 O 2 . This enhancement is attributed to an increase in H 2 O 2 utilization from 31% to 67%. Furthermore, FeOF/MoS 2 was loaded into the macropores of a SiC ceramic membrane to construct a catalytic membrane reactor. During continuous filtration of the p -NP solution, a removal rate of 60% was maintained over 12 h, indicating sustained catalytic stability. OH as the dominant reactive oxygen species (ROS) was identified in the degradation process through radical quenching tests and electron paramagnetic resonance (EPR) analysis. A possible degradation pathway was proposed based on intermediates detected by liquid chromatography-mass spectrometry (LC-MS). This work provides an effective strategy for boosting H 2 O 2 -driven catalytic oxidation in wastewater treatment under neutral conditions.

In this work, CoFe-layered double metal oxide (CoFe-LDO) was obtained by a co-precipitation-calcination route using CoFe-layered double metal hydroxide (CoFe-LDH) as precursor material, and then MoS 2 and chitosan-derived N-doped carbon co- modified CoFe-LDO composite catalyst (MoS 2 @CoFe-LDO/NCS) was prepared. This material was characterized by SEM, EDS, FTIR, XRD and XPS, and was synthesized to catalyze ozonation for the degradation of methylene blue (MB). The influence of CoFe-LDO dosage, O 3 flow rate, initial MB concentration, catalyst dosage, initial pH and coexisting compounds on MB removal efficiency were systematically investigated. The decomposition efficiency of 50 mg/L MB by 10%MoS 2 @CoFe-LDO/NCS reached 96.47% within 8 min under the conditions of 10% CoFe-LDO dosage (CoFe -LDO:CS), pH = 6.8, catalyst dosage of 0.4 g/L, Ozone flow rate of 1.87 mg/(L⋅min) and 25 °C. Stability tests and metal ion leaching experiments confirmed the excellent chemical stability and environmental compatibility of 10%MoS 2 @CoFe-LDO/NCS. Electrochemical characterization showed that 10%MoS 2 @CoFe-LDO/NCS possessed enhanced current density, redox activity and excellent electron transfer capability. Quenching experiments revealed that 1 O 2 , O 2 ∙ − and ∙ OH contributed to the MB degradation process, with O 2 ∙ − confirmed as the dominant reactive species.

Considering the unique layered structure and novel optoelectronic properties of individual MoS2 and MoSe2, as well as the quantum coherence or donor–acceptor coupling effects between these two components, rational design and artificial growth of in-plane mosaic MoS2/MoSe2 lateral heterojunctions film on conventional amorphous SiO2/Si substrate are in high demand. In this article, large-area, uniform, high-quality mosaic MoS2/MoSe2 lateral heterojunctions film was successfully grown on SiO2/Si substrate for the first time by chemical vapor deposition (CVD) technique. MoSe2 film was grown along MoS2 triangle edges and occupied the blanks of the substrate, finally leading to the formation of mosaic MoS2/MoSe2 lateral heterojunctions film. The composition and microstructure of mosaic MoS2/MoSe2 lateral heterojunctions film were characterized by various analytic techniques. Photodetectors based on mosaic MoS2/MoSe2 lateral heterojunctions film, triangular MoS2 monolayer, and multilayer MoSe2 film are systematically investigated. The mosaic MoS2/MoSe2 lateral heterojunctions film photodetector exhibited optimal photoresponse performance, giving rise to responsivity, detectivity, and external quantum efficiency (EQE) up to 1.3 A W–1, 2.6 × 1011 Jones, and 263.1%, respectively, under the bias voltage of 5 V with 0.29 mW cm–2 (610 nm), possibly due to the matched band alignment of MoS2 and MoSe2 and strong donor–acceptor delocalization effect between them. Taking into account the similar edge conditions of transition metal dichalcogenides (TMDCs), such a facile and reliable approach might open up a unique route for preparing other 2D mosaic lateral heterojunctions films in a manipulative manner. Furthermore, the mosaic lateral heterojunctions film like MoS2/MoSe2 in the present work will be a promising candidate for optoelectronic fields.

The reported high efficiency antimony chalcogenides devices are chronically adopted with organic hole transport layers (HTLs, i.e., Spiro-OMeTAD) because of their superior hole mobility and adequate energetic alignment. However, the high moisture sensitivity and high cost of organic HTLs will hinder their large scale application. Herein, a low-cost and stable carbon electrode is used as the back contact material for wide bandgap Sb2(S,Se)3 solar cells, and an eco-friendly MoS2 nanofilm with a suitable band structure and excellent carrier mobility is then employed to regulate the interface of Sb2(S,Se)3/carbon in terms of energy level alignment and carrier transportation. The thermal evaporated MoS2 effectively alleviates the serious recombination and remarkably improves the photoelectric conversion efficiency of wide bandgap Sb2(S,Se)3 thin-film solar cells by 50%, finally achieving an impressive efficiency of 6.1% with VOC of 0.76 V, JSC of 13.5 mA/cm2, and FF of 59%, which is among the highest efficiencies of carbon-based Sb2(S,Se)3 solar cells.

The intrinsic poor electrical conductivity, severe dissolution of K x S y intermediates, and inferior conversion reaction reversibility extremely impede the practical application of the transition-metal chalcogenides (TMDs) anode for potassium-ion batteries (PIBs). Herein, a rationally designed Cu 9 S 5 /MoS 2 /C heterostructure hollow nanocage was synthesized with assistance from metal-organic frameworks (MOFs) precursor. During the K-storage process, the homogeneously distributed the sulfiphilic nature of Cu 0 reaction product could act as a dual-functional catalyst, not only facilitating the rapid charge transfer but also effectively anchoring (K x S y ) polysulfides, thus boosting K-storage reactions reversibility during the conversion reaction process. When applied as an anode for PIBs, the as-prepared heterostructure exhibits excellent reversible capacity and long cycle lifespan (350.5 mAh g –1 at 0.1 A g –1 and 0.04% per cycle capacity decay at 1 A g –1 after 1000 cycles). Additionally, the potassium storage mechanism is distinctly revealed by in-situ characterizations. The nanoarchitecture designing strategy for the advanced electrode in this work could provide vital guidance for relevant energy storage materials.
