Developing efficient bifunctional electrocatalysts for water splitting remains challenging due to the antagonistic demands of oxygen and hydrogen evolution reactions (OER/HER). Herein, we present a ternary heterointerface non-precious catalyst, Ni/WC-Mo 2 C, for bidirectional HER and OER optimization. Combining in situ characterization and theoretical calculations, we demonstrate how this design overcomes conventional Schottky junction limitations: (i) The band gradient of the WC-Mo 2 C semiconductor heterojunction synergizes with metallic Ni's electron-donating properties to construct an "electron staircase" channel to enhance charge transfer while increasing active electron density and lowering the d -band center; and (ii) ternary interface-induced lattice strain buffering and localized electron redistribution stabilize high-valent Ni species and optimize intermediate adsorption/desorption energetics. This synergy resolves the OER-HER electronic conflict, endowing the catalyst with ultralow overpotentials of merely 26 mV for HER and 153 mV for OER at a current density of 10 mA cm −2 in 1.0 M KOH electrolyte. The assembled electrolyzer delivers a high current density of 1000 mA cm −2 at a low cell voltage of 1.73 V and sustains stable overall water splitting operation for an extended duration of 1200 h, outperforming noble-metal benchmarks (Pt/C||RuO 2 ). This work establishes a new paradigm for non-precious bifunctional electrocatalyst design through multicomponent heterointerface engineering.

Existing triboelectric nanogenerators (TENGs) for wearable sweat sensors are plagued by low power density, which restricts their practical application. This study focuses on boosting TENGs output power via a fluorinated bi-layer electronic textile (e-textile) fabricated by electrospinning rotary collection, enabling self-powered dual functionality: real-time electrochemical sweat sensing and human motion detection. The key design includes a PCLU-HFDD negative triboelectric layer (molecularly incorporated with hexadecafluorodecanediol to enhance electron affinity) and a poly(lactic- co -glycolic acid) (PLGA) positive layer. Rotary collection creates vein-like nanostructures on PCLU-HFDD yarns (6.2 μm roughness, 114.8° water contact angle), increasing contact area. The PCLU-HFDD TENG achieves a high power density of 0.66 W m −2 , an open-circuit voltage (Voc) of 117.08 V, and excellent stability over 35,000 contact-separation cycles. Critically, integrated with both sweat-sensing and motion-detection capabilities, the e-textile enables 180-min continuous glucose monitoring (under sedentary conditions) and recognition of human motions. This work confirms that the power enhancement not only overcomes the bottleneck of TENGs for wearable sensors but also facilitates dual-modal health monitoring, advancing the development of practical wearable bioelectronics.

Two-dimensional (2D/2D) heterojunction photocatalysts hold great promise for solar-driven antibacterial disinfection owing to their unique interfacial architectures and tunable electronic properties. However, insufficient interfacial electronic coupling and ineffective charge separation still hinder their practical performance. Here, a sulfur-doped g-C 3 N 4 /Ti 3 C 2 Tx-MXene (SCN/MXene) 2D/2D heterojunction is rationally designed to enable efficient charge separation and transfer, delivering superior solar-driven antibacterial activity with remarkable stability. Combined experimental and theoretical analyses reveal that sulfur doping modulates the electronic structure of g-C 3 N 4 , elevates its Fermi level, and strengthens interfacial electronic coupling with Ti 3 C 2 Tx-MXene, thereby enhancing the built-in electric field and facilitating charge transfer across the interface. Moreover, S-doping induces interfacial charge redistribution, enhancing O 2 adsorption and activation at Ti sites and thereby accelerating the generation of reactive oxygen species (ROS). Consequently, SCN/MXene achieves nearly complete inactivation of Escherichia coli , Staphylococcus aureus , and methicillin-resistant Staphylococcus aureus within 60 min under solar irradiation, outperforming most of the state-of-the-art photocatalysts.

To further improve the antibacterial performance of photocatalytic paper, a BiOBr/g-C 3 N 4 photocatalyst was synthesized via a two-step method, involving calcination for g-C 3 N 4 preparation followed by a solvothermal process for BiOBr/g-C 3 N 4 composite formation. The BiOBr/g-C 3 N 4 photocatalytic paper was fabricated by loading sunflower stalk pulp with a self-made hot-pressing device. In the composite, BiOBr and g-C 3 N 4 form tight heterojunctions through close contact, facilitating efficient charge separation and enhancing visible-light utilization. The resulting photocatalytic paper exhibits excellent recyclability and strong antibacterial activity, achieving 99.99% antibacterial efficiency and extending the fruit preservation time by fourfold compared with the control group. This study provides a green and scalable approach for developing recyclable and biodegradable photocatalytic packaging materials with potential applications in sustainable food preservation.

The development of highly active and cost-effective electrocatalysts for the urea oxidation reaction (UOR) is critical for facilitating scalable and sustainable hydrogen production. Heterointerface engineering has emerged as an effective strategy to enhance UOR performance by modulating electronic structures and improving charge transfer kinetics. Herein, we designed and fabricate a 3D heterostructure NiMn/Ni 3 S 2 supported on foam nickel (NiMn/Ni 3 S 2 /NF) via in situ growth of nickel-manganese layered double hydroxide (NiMn(OH) x ) on a self-supported sulfurized NF substrate. This unique petal architecture promotes active-site exposure and facilitates interfacial electron transfer between NiMn(OH) x and Ni 3 S 2 , which significantly enhances UOR catalytic activity. The as-optimized NiMn/Ni 3 S 2 /NF catalyst exhibits exceptional performance, achieving a low potential of 1.352 V (vs. reversible hydrogen electrode [RHE]) at 100 mA cm −2 and a Tafel slope of 13.34 mV dec −1 , outperforming most previously reported UOR catalysts. Moreover, the as-prepared NiMn/Ni 3 S 2 /NF catalyst demonstrates remarkable stability, retaining high catalytic activity and durability for over 120 h at 10 mA cm −2 . This study provides a rational strategy to design efficient and durable electrocatalysts for energy-related applications.

Intercalation-based exfoliation offers a cost-effective approach to producing 2D materials. While molecular intercalation surpasses ionic methods in preserving the crystallinity and intrinsic properties of 2D materials, its broader adoption is limited by weak driving forces and slow kinetics. To address these challenges, we propose an interlayer modulation strategy using H 3 PO 4 -amine complexes as mediators. Structural and molecular dynamics analyses demonstrate that these complexes regulate interlayer proton activity through strong hydrogen bonding, thereby optimizing interlayer dynamics to enable in situ PW 12 formation and efficient graphite exfoliation. The PW 12 intercalant shows excellent recyclability via simple alkaline hydrolysis and regeneration, establishing a sustainable route for graphene production. This work overcomes the barrier to molecular intercalation by rationally engineering complex molecular intercalation, achieving universal and high-throughput exfoliation of van der Waals layered materials.

Amid worsening energy shortages, the demand for clean energy and high-performance energy storage devices has surged, driving significant research interest in supercapacitor electrode materials. This study pioneered a novel hierarchical composite architecture integrating ball-milled Melaleuca bark-derived activated carbon (BAC) with nickel-cobalt layered double hydroxide (Ni-Co LDH) via a facile solvothermal method. Systematic optimization of synthesis parameters including the Ni: Co molar ratio, solvothermal reaction temperature/duration, and the BAC to NiCo-LDH mass ratio unveiled that controlled conditions induced a distinctive urchin-like spherical morphology, where vertically-aligned LDH microspheres uniformly anchor onto the porous BAC scaffold. This unique structure fosters a synergistic dual-function: BAC serves as a conductive backbone that mitigates LDH aggregation and enhances ion transport kinetics, while Ni₃Co₆-LDH delivers robust pseudocapacitance. Crucially, the optimal BAC/Ni 3 Co 6 composite achieved a remarkable specific capacitance of 587.5 F g − 1 , surpassing pristine BAC and Ni₃Co₆-LDH by 101.2% and 79.0%, respectively. Furthermore, the assembled asymmetric supercapacitor device demonstrated exceptional cycling stability, maintaining 99.7% coulombic efficiency after 6000 charge-discharge cycles. This work not only valorizes Melaleuca bark as a sustainable precursor for high-performance carbon materials but also establishes a rational design paradigm for engineering advanced biomass-derived composite electrodes.

In this study, we demonstrate a synergistic approach combining hydrothermal synthesis with laser annealing to fabricate Y 2 O 3 : x Eu 3+ phosphors ( x = 0.5, 1, 2, 5, 8, 10 %). When the doping concentration is 5 % Eu 3+ , the photoluminescence performance of the sample is the best, with the maximum emission intensity and a longer lifetime. The phosphor obtained by laser annealing, when excited by a 395 nm laser, emits light with a higher color purity than that obtained by traditional annealing; its thermal stability is also improved. Rietveld refinement confirms laser processing promotes preferential Eu 3+ occupation at low-symmetry C 2 sites, optimizing electric dipole transitions. Meanwhile, both Fourier transform infrared spectroscopy and absorption spectroscopy tests have proved that the performance of the laser-annealed samples is higher than that of the samples annealed in the furnace. In conclusion, laser annealing can be used as a new method for preparing high-performance rare earth luminescent materials.

Conventional urea industry faces dual challenges of high energy consumption and carbon emissions. Although electrochemical co-reduction of nitrates and carbon dioxide (CO₂) offers a promising route for green urea synthesis, its electrical-to-chemical energy conversion efficiency remains constrained by sluggish reaction kinetics and high electrical energy demand. Here, we design and report a nitrogen-doped porous carbon (NC) material embedded with dispersed copper‑nickel bimetal nanoparticles (CuNi/NC) for constructing the first example of a Zn-nitrate/CO₂ battery that can output electricity while generating urea with a superior energy efficiency of 1.51 mol urea kWh −1 and a urea production rate of 110 mg h −1 g cat −1 . The proposed assembled battery exhibits exceptional stability over 300 h , retaining high urea Faradaic efficiency at 36% and yield at 101 mg h −1 g cat −1 . In situ X-ray absorption spectroscopy, infrared spectroscopy, and density functional theory simulations confirm that the active metal sites facilitate substrate adsorption and stabilize critical intermediates (* N-C-N , *NH₂, and *NO), thereby effectively accelerating C N coupling. This work breaks the ‘high-energy, single-function’ bottleneck of traditional electrochemical systems, establishing an innovative ‘carbon-negative energy supply’ paradigm for carbon-neutral agriculture and decentralized energy systems.

Non-enzymatic electrochemical glucose sensors (NEGS) offer advantages over enzymatic counterparts, but conventional supporting scaffolds suffer from poor conductivity, limited surface area, and binder dependence. Herein, we present a strategy to fabricate high-performance, binder-free NEGS based on a hierarchical laser-induced graphene/carbon fiber framework (LW-CFF-B) functionalized with NiO nanoparticles. The 3D porous LW-CFF scaffold is engineered by in-situ carbon fiber felt (CFF) enhanced LIG using 1,4-phenylenediboronic acid (PA) modified liquid benzoxazine (PGE-a) as the precursor. PA serves a dual role in enhancing carbon yield and improving electrical conductivity (sheet resistance reduced from 2.54 to 1.23 Ω/sq). Moreover, PA promotes the formation of a hierarchical porous carbon architecture, which is beneficial for facilitating electrochemical performances of the obtained carbon product. Subsequent laser assisted deposition of NiO nano-layer on LW-CFF-B scaffold yields the LW-CFF-B-Ni electrode. This optimized architecture combines mechanical integrity with exceptional electrocatalytic properties, leading to outstanding glucose sensing performance: ultrafast response (1.2 s), ultrahigh sensitivity (5758 μA mM⁻¹ cm⁻²), a low detection limit (0.16 μM), and excellent selectivity against common interferents. The developed sensor demonstrates appreciable recoveries (91.1% to 107.3%) regarding glucose concentration in beverages. These outstanding analytical results demonstrate significant potential for this sensor in precise glucose monitoring.

Lithium‑sulfur (Li S) batteries, despite their ultrahigh theoretical energy density and cost-effectiveness, face persistent challenges such as sluggish redox kinetics, severe polysulfide shuttling, and insufficient sulfur utilization. Herein, we propose a novel integrated Ni/V 2 O 3 heterostructure anchored on self-supporting carbon cloth (Ni/V 2 O 3 @CC) as a high-efficiency sulfur host to address these limitations. The three-dimensional conductive carbon cloth framework eliminates the need for binders while ensuring robust structural integrity and efficient electron transport. The rationally designed Ni/V 2 O 3 heterostructure synergistically combines metallic Ni, which offers catalytic active sites for accelerated sulfur conversion, with polar V 2 O 3 , enabling strong chemisorption of polysulfides. Experimental and theoretical analyses reveal that the abundant interfacial polar-catalytic centers in the heterostructure significantly suppress polysulfide shuttling and enhance redox kinetics. Consequently, the self-supporting Ni/V 2 O 3 @CC cathode demonstrates excellent cycling stability at 1.0C, delivering a high initial discharge capacity of 650 mAh g −1 even at 5.0C with 84% capacity retention after 100 cycles. Notably, it maintains a remarkable discharge capacity of 580 mAh g −1 even under a high mass loading of 4 mg cm −2 . This work establishes a new paradigm for integrating multifunctional heterostructures with freestanding substrates, paving the way toward practical high-energy-density Li S batteries with extended cycle life.

The urea oxidation reaction (UOR), with its low theoretical potential, can replace the oxygen evolution reaction (OER) at the anode in water electrolysis, thereby reducing the thermodynamic barrier of electrochemical water splitting. However, in practical UOR electrocatalysts, the adsorption competition between urea and OH⁻ constitutes a kinetic bottleneck. Conventional catalysts lack dynamic regulation means, which ultimately leads to the occurrence of competitive adsorption. In this study, we constructed a CuxS/FeS/NF heterojunction electrocatalyst via hydrothermal methods, achieving highly efficient catalysis for UOR-assisted overall water splitting. The heterojunction features an open and disordered hierarchical porous structure, significantly increasing the specific surface area and active site density (with a double-layer capacitance of 8.33 mF cm -2 ). More importantly, the reversible Cu + /Cu 2+ valence cycling on the heterojunction surface dynamically modulates urea adsorption sites, addressing the issue of OH -occupying active centers and accelerating reaction kinetics (Tafel slope as low as 26.28 mV dec -1 ). In-situ Raman tests confirm that Cu 2+ forms strong coordination with -NH₂ via empty orbitals, while Cu + weakens the adsorption of OH⁻ through high electron density; the two species synergistically accelerate the reaction kinetics. Electrochemical tests reveal that in the UOR||HER system, CuxS/FeS/NF only requires a potential of 1.35 V vs. RHE to achieve a current density of 10 mA cm -2 , while for the HER, it needs merely 78 mV to reach the same current density. When applied to UOR-assisted overall water splitting in a 1 M KOH + 0.33 M urea electrolyte, the system requires only 1.440 V vs. RHE cell voltage to deliver a current density of 50 mA cm -2 and maintains stable operation for 60 hours, with a urea degradation rate of 66.4% after 20 hours. This work, through the dynamic regulation mechanism of copper valence cycling, provides a novel approach for designing UOR catalysts with both high activity and stability, holding significant application potential in low-energy hydrogen production and wastewater treatment.
