A BiOBr/reduced graphene oxide (RGO) composite aerogel with BiOBr nanoplates grown on an interconnected three-dimensional RGO-based porous network was prepared by one-pot hydrothermal method using l-lysine as a reducing agent and the cross-linker. Its enhanced adsorption toward pollutants owing to its large Brunauer–Emmett–Teller specific surface area and spongy nature, improved light absorption due to its extremely lightweight nature and the RGO promoting photogenerated charge separation contributed to the BiOBr/RGO aerogel’s enhanced activity for photocatalytic degradation in an aqueous system. The BiOBr/RGO aerogel also showed high stability and can be easily separated from the reaction systems for recycling. The facile one-pot method has been proved to be generic in the formations of different semiconductor embedded RGO aerogels like BiOX/RGO (X = Cl and I), CdS/RGO and Fe2O3/RGO aerogels, which combine the advantages of enhanced photocatalytic activity with facile recycling for applications in aqueous photocatalytic reaction systems.

3D/2D Bi 2 O 2 CO 3 /rGO composites were synthesized successfully. • Bi 2 O 2 CO 3 /rGO/GCE were used for high-sensitive electrochemical CAP detection. • Wide linear range (0.001–100 μM) and low LOD of 0.362 nM (S/N = 3) are obtained. Chloramphenicol (CAP) remains prevalent in aquaculture despite its classification as a Group 2 A carcinogen. Given the associated health risks, establishing robust detection methods for CAP is imperative. Herein, we innovatively propose the three-dimensional (3D) flower-like Bi 2 O 2 CO 3 /rGO composites for CAP electrochemical sensing. The best sensing parameters (pH, scan rate, accumulation conditions) were systematically investigated. As a result, the Bi 2 O 2 CO 3 /rGO/GCE sensor exhibits a peak current density of 381.91 µA/cm 2 , ultra-low detection limit (0.362 nM), and two wide linear ranges (0.001–10 μM, 10–100 μM), enabling both trace and high-concentration quantitative detection of CAP. These high sensing performances could be ascribed to the synergistic effect between rGO and Bi 2 O 2 CO 3 , which improves the stability of Bi 2 O 2 CO 3 /rGO composites. Their interfacial interaction accelerates electron transfer, lowers activation energy, and forms an efficient 3D electron/mass transport network. This sensor also applied in detecting CAP in lake water and milk samples with satisfied recovery rates. These findings underscore the Bi 2 O 2 CO 3 /rGO/GCE as a promising platform for sensitive CAP monitoring in environmental and food safety applications.

Silicon suboxides (SiO x ) are promising anodes for lithium-ion batteries, but their practical application is hindered by severe volume fluctuation and sluggish (de)lithiation kinetics. Herein, a hierarchical disproportionated-SiO x -based composite, D-SiO x @NC/C@CNTs/rGO-2, consisting of disproportionated SiO x (D-SiO x ) with in situ generated Si/SiO 2 domains, a nitrogen-doped carbon/carbon (NC/C) interphase, and an interconnected CNTs/rGO conductive framework, is constructed through thermal disproportionation, interphase engineering, and multidimensional conductive-network design. Thermal disproportionation induces the in situ formation of Si domains embedded in a SiO 2 buffering matrix, in which Si provides lithium-storage activity while SiO 2 alleviates volume variation and enhances structural stability. Meanwhile, a conformal nitrogen-doped carbon interphase mitigates chemo-mechanical stress and stabilizes the active interface, and the intertwined CNTs/rGO framework builds an efficient conductive network. As a result, the optimized anode delivers a reversible capacity of 876.4 mAh·g −1 after 500 cycles at 0.5 A g −1 , with a capacity retention of 83.7%, while electrode swelling is suppressed to ≈52% versus ≈159% for bare D-SiO x . Operando electrochemical impedance spectroscopy combined with distribution of relaxation times reveals reduced interfacial polarization and faster apparent Li + transport. A pre-lithiated LFP||D-SiO x @NC/C@CNTs/rGO-2 full cell also shows an initial Coulombic efficiency of 96.15% and stable cycling over 200 cycles.

Solar-driven interfacial evaporation (SDIE) holds immense potential for sustainable desalination, yet current solar evaporators remain severely obstructed by the limited evaporation efficiency, inherent mechanical fragility and the complex fabrication of robust photothermal layers. Herein, we propose a “waste-to-wealth” structural engineering and in situ interfacial coupling strategy to develop a highly robust, 3D evaporator (CuO/rGO/PVA/SA-CF). By utilizing recycled waste carbon fiber needle-punched felt as a rigid skeletal constraint for a hydrogel-derived porous matrix, the device achieves an exceptional loading stress of 54.61 MPa at 3% strain, fundamentally resolving the issue of structural deterioration under demanding operational conditions. Furthermore, a highly efficient, single-step vacuum-assisted thermal process was designed to drive a synchronous transformation: the in-situ oxidation of copper alongside the reduction of graphene oxide (GO). This simultaneous oxidation-reduction mechanism yields a highly coupled photothermal architecture, delivering broadband solar absorbance of 95% and effectively reducing the equivalent evaporation enthalpy to 1587.02 kJ kg −1 . Under 1 sun illumination (1 kW m −2 ), the evaporator exhibits a high evaporation rate of 2.142 kg m −2 h −1 with a photothermal conversion efficiency of 91.8%. Furthermore, the device maintains a stable evaporation rate of 1.753 kg m −2 h −1 even in high-salinity brine (20 wt%), demonstrating outstanding salt-rejection performance. This work establishes a scalable, mechanically durable, and eco-friendly paradigm for next-generation solar desalination systems.

Addressing the urgent demand for energy conservation, efficient thermal storage, and safety protection in the modern building sector, this study fabricates a temperature-adaptive multifunctional composite phase change material (PEG/RCP). By encapsulating polyethylene glycol (PEG) within high-porosity anisotropic P/N co-doped rGO aerogels prepared via directional freezing, the composite achieves a critical balance between high latent heat (169.6 J·g −1 ) and low thermal conductivity (0.397 W·m −1 ·K −1 ). Comprehensive molecular dynamics simulations reveal that heteroatom doping induces significant phonon spectrum mismatch at the interface. This mismatch substantially enhances interfacial thermal resistance, facilitating a synergistic “heat storage-thermal insulation” effect. The composite exhibits robust flame retardancy with a 53.3% reduction in peak heat release via gas-phase dilution, condensed-phase char formation, and phase change heat absorption. Furthermore, it achieves superior electromagnetic shielding effectiveness (greater than 75 dB) dominated by absorption loss through multiple reflections within the porous framework, interfacial/dipole polarization, and conductive loss. Outdoor building thermal management tests confirm that the PEG/RCP interlayer effectively suppresses indoor temperature fluctuations and delays heat transfer, showcasing exceptional temperature-adaptive thermal regulation performance. Consequently, this work offers a promising strategy for designing advanced materials for multifunctional thermal management in next-generation smart buildings.

Developing sensing interfaces that simultaneously integrate catalytic activity, efficient charge transfer, and structural stability remains a major challenge for high-performance non-enzymatic glucose sensing. Herein, a CuS/Ti₃C₂/rGO ternary composite was fabricated through a combination of liquid-phase precipitation and self-assembly. Structural, surface, and electrochemical studies revealed that the enhanced sensing performance originated from the synergistic integration of catalytic CuS, conductive Ti₃C₂, and rGO-assisted structural protection. Under optimized conditions, the sensor exhibited a fast response time of 3.7 s, a wide linear range of 0.01–10.35 mM, and a low detection limit of 3.33 µM (S/ N = 3). In addition, satisfactory selectivity, stability, repeatability, and reproducibility were achieved. Recoveries of 98.1–105.0% were obtained in commercial oral liquids and fruit juice samples, demonstrating good analytical reliability in complex matrices. These findings indicate that the proposed catalysis-conduction-protection strategy provides an effective design principle for constructing high-performance non-enzymatic glucose sensing interfaces.

In order to achieve rapid extraction and sensitive detection of capsaicinoids, this study combined glass bead-assisted ultrasound extraction with a Bi2S3/rGO/MWCNT-COOH-modified screen-printed electrode. By integrating ethanol–water solvents and glass beads, the ultrasonic cavitation effect was enhanced, reducing the extraction time from 50 minutes to 22 minutes while maintaining high efficiency. The composite-modified SPE exhibited superior electrochemical performance, achieving a detection limit of 26 nM through differential pulse voltammetry (DPV). The response surface methodology optimized extraction parameters and real-sample validation demonstrated high reliability (recovery: 94.70–110.50%) and consistency with HPLC results. This approach offers a rapid, eco-friendly solution for on-site analysis of capsaicinoids in food safety and quality control applications.

Conductive hydrogels with self-healing, tissue-adhesive, injectable, antibacterial, and biocompatibility properties offer significant potential for wound dressing applications in healthcare. Herein, we have developed a multifunctional hydrogel based on carboxymethyl chitosan (CMCS) and oxidized dextran (ODex) incorporated with Ag@rGO nanocomposites through Schiff base reaction. The physicochemical characteristics of the fabricated ODex/CMCS/Ag@rGO (OCR) hydrogel were investigated by FT-IR, 1 H-NMR, SEM, XPS and TEM. The in vitro experiment results confirmed that the prepared QCR hydrogels exhibited favorable injectability with shear-thinning behavior, self-healing behavior, and suitable swelling capacity (1500~1700%). The ability to illuminate miniature light bulbs proved the conductivity of hydrogels. Remarkably, the material displayed robust adhesion to diverse substrates, including metals, glass, rubber, plastics, and biological tissues (human skin, porcine skin, heart, spleen, and kidney), maintaining stable adhesion under mechanical stress when applied to porcine skin. Antimicrobial testing revealed inhibition zones against both Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ). Furthermore, when the hydrogels were co-cultured with NIH 3T3 cells, the cell viability, cell morphology and cell migration were almost unaffected, showing good biocompatibility. This study provided a simple strategy for the preparation of multifunctional hydrogel-based wound dressings, which could have the potential for the future management of skin injuries.

Phase interface engineering plays an essential role in the design and development of effective electromagnetic wave (EMW) absorption materials and energy storage devices. Nevertheless, the development of multifunctional materials that can simultaneously tackle these challenges remains a significant difficulty. In this study, we developed multifunctional defect-rich 1T/2H-WX2/RGO (X = S, Se) nanosheets utilizing a simple solvothermal and freeze-drying technique. The synthesized 1T/2H-WX2/RGO nanosheets exhibited superior EMW absorption and electrochemical characteristics. The effective absorption bandwidth (EAB) reached 7.68 GHz at a thickness of 3.10 mm. This excellent performance can be attributed to various loss mechanisms, including conductive loss, defect-induced dipole polarization loss and interface polarization loss. Moreover, the 1T/2H-WS2/RGO-15 nanosheets attained a high specific capacitance of 390.44 F g−1 at a current density of 1 A g−1. In contrast, the 1T/2H-WSe2/RGO-4 nanosheets demonstrated impressive cycling stability of 71.81% after 5000 cycles, which can be attributed to the active sites provided by its rich heterogeneous interface. The energy density of the 1T/2H-WS2/RGO-15 nanosheets was measured to be 4.27 Wh kg−1 at a power density of 400 W kg−1. This research offers valuable insights into the development of multifunctional materials that can serve as EMW absorbers and supercapacitor electrodes.

In the marine environment, chloride ion is the main reason for the accelerated corrosion of carbon steel. Meanwhile, in zinc-containing coatings, the chloride-bearing corrosion product Zn 5 (OH) 8 Cl 2 ·H 2 O exhibits a theoretical volume expansion rate as high as 260%, which easily precipitates coating cracking. In this study, a two-dimensional zirconium phosphate-reduced graphene oxide (ZrP-rGO) nanomaterial with a highly negative potential surface was fabricated. Its two-dimensional architecture significantly prolongs the diffusion pathways of corrosive species. Moreover, the highly negatively charged surface generates strong electrostatic repulsion against chloride ions, effectively acting as a selective ionic barrier. This dual action suppresses the formation of high-volume-expansion zinc corrosion products (e.g., Zn₅(OH) 8 Cl 2 ·H 2 O), thereby preserving coating integrity and enabling zinc in low-zinc coatings to fully exert its chemical shielding effect. Specially，after 30 days of immersion, the coating with 1 wt% ZrP–rGO show a |Z| 0.01Hz of 3.32 × 10 8 Ω·cm 2 and a corrosion current density of 2.65 × 10 −10 A·cm −2 , as confirmed by EIS and Tafel analyses. These values are five orders of magnitude higher and four orders of magnitude lower than those of a pure 60 wt% zinc coating, significantly enhancing the coating's corrosion resistance. Salt spray testing demonstrates that the 1 wt% ZrP-rGO coating exhibits excellent corrosion resistance. This work provides new insights into improving the corrosion resistance of zinc coatings.

Rational design and construction of cathode materials with high ion transport coefficient and high electrical conductivity is of great importance for improving the reaction kinetics of Li-ion batteries (LIBs). Herein, we develop the three-dimensional (3D) LiFePO 4 @reduced graphene oxide/carbon nanofibers (LiFePO 4 @rGO/CNFs) to serve as flexible cathodes for LIBs. Through the electrospinning technique combined with the subsequent pyrolysis , the composite nanofiber precursors have been successfully converted into flexible electrodes . As demonstrated, the as-prepared electrodes present uniform nanofibers, in which the rGO sheets are evenly attached to CNFs , and LiFePO 4 nanoparticles are homogeneously distributed in CNFs. Benefited by the structural advantages and the improving conductivity, the optimum LiFePO 4 @rGO/CNFs cathode exhibits a high initial capacity of 167 mAh g −1 at 0.5 C, and maintains a reversible capacity of 150 mAh g −1 after 200 cycles at 1 C. Galvanostatic intermittent titration technique (GITT) shows that LiFePO 4 @rGO/CNFs has a high ion diffusion rate (8.82 × 10 −12 cm 2 s −1 ), further suggesting that such 3D structures are appropriate as cathode materials for LIBs. These findings demonstrate that the 3D continuously conductive network of LiFePO 4 composites is a promising cathode material for LIBs.

g-C 3 N 4 has attracted much attention in the field of photocatalysis. However, its high carrier recombination rate has always been an obstacle in practical application. g-C 3 N 4 -based heterostructures with an intimate interface contact is considered to be an effective solution to improve the separation and transmission of photogenerated carriers. Herein, an oxygen vacancy-mediated direct solid phase integration strategy is proposed to synthesize a 0D/2D/2D LaNiO 3 /RGO/g-C 3 N 4 S-scheme heterostructure with interface chemical bonds. The optimized LaNiO 3 /RGO/g-C 3 N 4 sample showed excellent hydrogen evolution rate of 1375 μmol/g/h, which is far superior to those of pristine g-C 3 N 4 (46 μmol/g/h), LaNiO 3 /g-C 3 N 4 (143 μmol/g/h), RGO/g-C 3 N 4 (307 μmol/g/h) and mechanically mixed sample LaNiO 3 -RGO-g-C 3 N 4 (625 μmol/g/h). Also, it is comparable to many g-C 3 N 4 -based heterojunction photocatalysts known at present. The improved performance can be attributed to interfacial charge transfer promoted by interfacial chemical bonds served as charge transfer channels and the high redox capacity of S-scheme charge transfer. This work opens up a new avenue for the predictive design of reinforced heterojunction with enhanced photocatalytic performance.
