Black phosphorus (BP) nanosheets were synthesized through high-energy ball milling and liquid-phase exfoliation. The impact of BP on the tribological characteristics of castor oil (CO) was evaluated by using a four-ball test. The lubrication and extreme pressure performance of oil-based lubricants containing various mass fractions of BP nanosheets were examined in steel/steel frictional pairs, with the results compared to pure CO. Experimental results demonstrate that BPNS significantly fortifies the load-carrying capacity and antiwear resistance of the base oil, achieving a 43% reduction in friction and an 83% decrease in wear volume, alongside a 54% increase in extreme pressure performance. Molecular dynamics simulations revealed that when BP was introduced into the system, the friction force decreased by 44.4%. These enhancements are primarily attributed to the formation of the tribo-chemical layer consisting of iron oxides (Fe2O3, Fe3O4) and POx/P–O–C and the physical adsorption film on the worn surface. The interlayer shear properties of BP nanosheets also contribute significantly to reducing friction and mitigating wear.

In recent years, transition metal phosphorus trichalcogenides have been successfully applied on multiple occasions in the field of photoelectrochemical (PEC) photodetection. In this work, high-quality SnPS₃ crystals were synthesized via the chemical vapor transport method and then exfoliated via liquid-phase exfoliation method for being utilized as active materials in the PEC-type photodetectors. The device exhibited excellent self-powered response and a broadband detection range from 400 nm to 900 nm in an acidic environment. Under simulated sunlight illumination, it achieved a photocurrent density of 31.2 μA cm⁻², responsivity of 195 μA W⁻¹, with the rise and fall times of 75 and 91 ms, respectively. The best photoelectric response performance appeared under 400 nm light excitation, with a photocurrent density and responsivity of 11.04 μA cm⁻² and 175.19 μA W⁻¹, respectively. Furthermore, after approximately 6200 s of long-term cycling test and 66 days of air stability test, the detector’s photocurrent density retention rates were of 89.23% and 81.05%, respectively. This work implies the significant potential of SnPS₃ for being hired in the field of self-powered broadband photodetection.

Transition metal phosphorus sulfides, owing to their unique 2D layered structure and inherent cost-effectiveness, have emerged as promising electrocatalysts in the urea oxidation reaction (UOR). However, they encounter a notable challenge that the dense stacking of their layers drastically restricts the exposure of electrochemically active sites and diminishes electron transfer efficiency, thereby directly leading to subpar performance in the UOR. Herein, based on an intercalation–exfoliation method, a novel layer structural regulation strategy for achieving few-layer FePS3 has been proposed. The results demonstrated that the interlayer stacking of pristine FePS3 could be significantly diminished, with the average layer thickness reducing from 25 nm to an impressive 8 nm. Benefiting from the changes in the layer structure, the few-layer FePS3 exhibits excellent UOR activity, requiring only 1.371 V (vs. RHE) to deliver 10 mA cm−2 and maintaining a low potential of 1.545 V at 300 mA cm−2, which is due to the enhanced exposure of electrochemically active sites and the increased electron transfer efficiency. Simultaneously, the mechanism of enhancing the UOR has been elucidated through in situ Raman and XPS studies. When the UOR of the FePS3/NF couples with the HER of Pt to achieve full electrolysis, the few-layer FePS3/NF system could achieve a urea degradation efficiency of 67.88% after 12 hours, significantly exceeding that of the pristine FePS3/NF system (50.3%). Hence, this work presents a novel strategy for regulating the layered structure of 2D FePS3 to fulfil the synergistic demands of highly efficient urea degradation and low-energy H2 production.

Ionogels have attracted considerable attention in wearable strain sensors owing to their inherent flexibility, skin-like conformability, and capability for detecting biomechanical signals. However, most existing ionogel-based flexible strain sensors still suffer from limited stretchability, low mechanical strength, inadequate self-adhesion, and poor breathability, which constrain their practical applications. In this work, a strategy for constructing fiber-structured ionogels was presented, integrating excellent mechanical robustness, enhanced breathability, reliable self-adhesion, and multistimuli sensing capabilities. An ultrathin ionogel (0.1 mm thick) was fabricated via an entangled network formed through physical interactions such as hydrogen bonding and electrostatic forces between thermoplastic polyurethane (TPU) and ionic liquid (IL) fibers, and reinforced with few-layer black phosphorus (BP), without the use of cross-linking agents or chemical initiators. The resulting ionogel (BP@TPU ionogel) exhibits a high tensile strength of 17.18 ± 1.35 MPa, toughness of 13.14 ± 1.38 MJ m–3, modulus of 8.99 ± 1.65 MPa, and a notable elongation of 230.33 ± 2.57%, along with exceptional breathability (190.94 g m–2,24 h). Moreover, the incorporation of a waterborne polyurethane (WPU) adhesive layer confers strong adhesion, ensuring durable and repeatable self-adhesive performance even under humid conditions or prolonged use. The BP@TPU ionogel-based strain sensor leverages a synergistic dual conductive framework─comprising both electronic BP and IL pathways─to deliver high sensitivity (gauge factor, GFmax = 2.05) and a wide sensing range (0–110%). The device reliably captures a broad spectrum of human physiological signals, including various joint movements, real-time temperature fluctuations, and subtle motions such as swallowing and respiration. Even after 1000 mechanical cycles, the sensor maintains stable signal output, underscoring its great promise for applications in next-generation smart wearables, electronic skin, and human–machine interfaces.

Red phosphorus (RP) is a promising anode material for sodium-ion batteries (SIBs) due to its high theoretical capacity and cost-effectiveness. However, its practical use is constrained by poor electronic conductivity and severe volume expansion during cycling. Herein, we introduce a new strategy to synthesize phosphorus/carbon (P/C) composites enriched with phosphorus-oxygen-carbon (P– O –C) bonds, achieved by high-energy ball milling of CO 2 -derived oxygen-rich electrolytic carbon (EC) with RP. This approach enhances the conductivity and structural stability of RP while effectively mitigating volume changes during charge-discharge cycles. Electrochemical evaluation reveals that the P/EC composite exhibits outstanding performance, maintaining a high capacity of 871.6 mAh g −1 after 200 cycles at 0.26 A g −1 with a retention rate of 88.6 %, and delivering 340.2 mAh g −1 after 2000 cycles at 2.6 A g −1 . This work demonstrates the potential of integrating CO 2 -derived EC with RP to create advanced anode materials with enhanced stability and high-rate capability, paving the way for next-generation SIBs.

Hydrogen production technology by water electrolysis highly relies on active and durable electrocatalysts for oxygen evolution reaction (OER). For Fe-containing electrocatalysts, the surface evolution during OER generally induces the dissolution of Fe into electrolyte. The excessive changed and dynamic surface quite puzzles the initial catalyst design, and moreover the excessive Fe loss could result in instability of the reconstructed surface, which might affect the formation of active species and the durability on the reaction interface. Here, we introduced a functional component of ethylenediamine-intercalated black phosphorus (eda-BP) to the Ni 1.5 Fe 0.5 B. Through electronic interaction between eda-BP and Ni 1.5 Fe 0.5 B, the excessive Fe loss during surface reconstruction process is effectively suppressed and the formation of Ni oxyhydroxide active species is facilitated, thereby enhancing the stability of the catalytic reaction interface. At the meantime, the ⁎ OH adsorption capacity on the reaction surface is regulated and the heterostructure catalyst exhibits significantly improved OER reaction kinetics. The Ni 1.5 Fe 0.5 B/eda-BP demonstrates a low OER overpotential ( η = 221 mV) at the current density of 10 mA cm −2 and sustainable activity. This work offers a facile strategy for improving the reactive interface for efficient and durable OER process.

Photocatalytic water splitting for hydrogen production is an ideal green and energy-efficient strategy. However, due to severe recombination of photogenerated electron-hole pairs, and sluggish kinetics of the hydrogen evolution reaction (HER) on the catalyst surface, the current photocatalytic hydrogen production efficiency still fails to achieve satisfactory results. Therefore, in this study, a two-dimensional/two-dimensional (2D/2D) heterojunction BPM (BP/Mn x Cd 1-x S) was constructed via electrostatic self-assembly. The prepared 1 % BPM exhibited excellent photocatalytic hydrogen production performance (55.8 mmol g −1 h −1 ), demonstrating a two-fold improvement in hydrogen evolution performance compared to the MCS-7 solid solution. Comparative analysis of results from multiple characterization techniques revealed that the high-efficiency photocatalytic hydrogen production performance of BPM originates from the introduction of black phosphorus (BP) and the formation of the 2D/2D heterojunction: BP acts as a co-catalyst to inhibit the recombination of photogenerated electrons, while the heterojunction structure effectively separates charges, enabling efficient generation and utilization of photogenerated carriers. This study clarifies the role of BPM in photocatalytic water splitting, aiming to achieve efficient photocatalytic hydrogen production.

A novel, environmentally friendly flame retardant (FB) composite was developed by integrating cross-linked kraft lignin (FSK) and black phosphorus (BP) for thermoplastic polyurethane (TPU) applications. FSK was prepared by C C Friedel-Crafts crosslinking between benzene rings and amino/silanization between hydroxyl groups of lignin. The FB, with an optimal FSK:BP ratio of 7:3 at 1 wt%, significantly improved the flame retardant properties of TPU. It achieved a limiting oxygen index (LOI) of 30.7%, a 91% increase in char residue, and UL-94 V-0 classification, surpassing the performance of pure TPU. Cone calorimeter tests revealed a 21.26% reduction in total heat release (THR) and a 37.06% reduction in peak heat release rate (PHRR). The flame retardancy mechanism involved BP and FSK's crosslinked structure catalyzing the formation of a stable graphitized char layer, while FSK, through its nitrogen and silicon components, released inert gases such as NH 3 /CO 2 , enhancing the stability of the char layer. The synergistic effect provided dual-phase flame retardancy (condensed-phase and gas-phase) at low additive levels, maintaining mechanical properties (tensile strength: 20.1 MPa). This approach, using biomass-derived lignin and low levels of BP, offers an environmentally friendly alternative to traditional flame retardants, making it a promising strategy for high-safety applications.

Ethylene propylene diene monomer (EPDM) is widely used in automotive and HVAC sealing systems, where its long-term thermal-oxidative stability and fire safety are critical, yet challenged by high-temperature operation and flammability risks. To address these limitations, this work develops a surface-engineered boron nitride synergist (h-BN@PDT) through NaOH-assisted hydroxylation and subsequent functionalization with hexachlorocyclotriphosphazene and tannic acid. The modified h-BN@PDT integrates phosphorus/nitrogen flame-retardant groups and radical-scavenging phenolic hydroxyls, achieving multifunctional enhancements in EPDM composites. Thermal-oxidative aging tests (125 °C, 168 h) demonstrated exceptional stability, with 11.12 MPa of tensile strength for aged h-BN@PDT/EPDM, compared to 2.78 MPa of traditional flame-retardant EPDM without BN fillers. Doubling oxidation induction time was attributed to enhanced thermal conductivity and pyrolysis activation energy, which contributed to BN’s oriented heat-transfer pathways and phenolic hydroxyl-mediated radical quenching. Flame retardancy evaluations revealed that h-BN@PDT can effectively replace partial conventional flame retardants while enabling the composite to achieve a UL-94 V-0 rating with only 25 phr of flame-retardant loading. Cone calorimetry tests demonstrated a significantly reduced heat and smoke release rate. Mechanistic studies identified that h-BN@PDT enhances flame retardancy through the synergistic effects of the lamellar barrier effect and promoted catalytic charring capability. These mechanisms effectively inhibit heat transfer, block the diffusion of pyrolysis products, and restrict oxygen access, thereby substantially improving the flame-retardant efficiency of conventional systems. This work resolves the inherent trade-offs among flame retardancy, aging resistance, and mechanical integrity in EPDM, offering a scalable strategy for next-generation sealing materials in electric vehicles and high-temperature engineering applications.

Asymmetric two-electrode device achieves an energy density of 60.44 Wh kg⁻¹ at 1 A g⁻¹ with a power density of 637.21 W kg⁻¹, underscoring its supercapacitor (SC) potential. In addition, platinum (Pt) electrodeposition enhances the catalytic activity of the PANI@WO₃-P/NF electrode for methanol oxidation, paving the way for advanced energy conversion in next-generation direct methanol fuel cells. The maximum current density reaches 19.85 mA mg⁻ 1 Pt, and the electrode retains 80.64% of its original activity even after 1000 cycles, demonstrating that the Pt/PANI@WO-P/NF electrode has good stability.

Radiation tolerance is a crucial parameter for MAX phases in nuclear structural applications. While metallic A-site nanolayers are traditionally regarded as the primary contributors due to their low M A -A M antisite defect formation energies, which facilitate defect accommodation and energy dissipation, recent advances in covalent MAX phases have opened new avenues for enhancing radiation damage mechanisms through X-site elements. In this work, we demonstrate that nonmetallic A-site and X-site elements play a decisive role in governing radiation response behavior. Unlike conventional metallic A-site MAX phases, which predominantly exhibit c -axis swelling under irradiation, the covalent variants Zr 2 SeC and Zr 2 SeP show anisotropic lattice expansion, characterized by a -axis-dominated distortion. This distinct behavior arises from strain redistribution mediated by variations in M-A-M bond angles, offering a mechanistic pathway to mitigate radiation-induced dimensional changes. Notably, these covalent MAX phases exhibit divergent structural evolution: Zr 2 SeC undergoes significant lattice swelling and partial amorphization, whereas Zr 2 SeP retains its hexagonal crystalline structure under identical irradiation conditions. We attribute this difference to the unique bonding configuration of Zr 6 X octahedra, where X’s electronegativity modulates Zr-Se bond cohesion and the energetics of Zr Se -Se Zr antisite defects. The combined effects of reduced antisite defect formation energy and lowered vacancy migration barriers collectively confer exceptional intrinsic radiation tolerance to Zr 2 SeP grains. These findings provide a design framework for identifying radiation-resistant MAX phases with optimized structural stability for advanced nuclear applications.
