SnCl 2 ·2H 2 O was applied as tin source to uniformly deposit SnO 2 nanoparticles (1–5 nm) on rGOs by adjusting the mass ratio of SnCl 2 ·2H 2 O and rGO via a hydrothermal reaction. During the hot-press sintering, the Sn and O atoms of SnO 2 @rGO gradually diffused into Mg matrix and formed Mg 2 Sn and MgO nanocrystals along the interface between rGO and Mg matrix with a semi-coherent relationship. The resulting heterogeneous interface structure acts like “stitches” to sew the rGO “patches” onto the Mg “cloth”, which largely enhanced the interfacial bonding. As reinforcement, SnO 2 @rGO caused significant grain refinement in ZK61 alloy, especially leading to a hierarchical architecture with micro-nano grains ascribed to the heterogeneous sites on rGO. The strength and ductility of SnO 2 @rGO/ZK61 composite (UTS of 375 MPa, YS of 344 MPa, and EL of 20.6%) were simultaneously enhanced than those of ZK61 alloy (UTS of 309 MPa, YS of 276 MPa, and EL of 17.3%), which successfully overcomes the traditional strength-ductility trade-off in Mg alloys. This work provides a novel design strategy for high-performance graphene reinforced Mg matrix composites by interfacial engineering.

A new type of highly efficient ternary rGO/COF-C4N/NH2-Bi2O3 heterojunctions was designed and synthesized by solvothermal and ultrasonic methods, and was applied to photocatalytic degradation of chlorophenol in water. The results show that the photocatalytic activity and stability of rGO/COF-C4N/NH2-Bi2O3 for the degradation of o-chlorophenol (2-cp) was significantly increased as compared with that of pure Bi2O3, COF-C4N, and COF-C4N/NH2-Bi2O3. The photocatalytic degradation rate for 2-cp by rGO/COF-C4N/NH2-Bi2O3-5% get to 83.7% and 97.4%, and the highest degradation rate constants are 0.0072 min⁻¹ and 0.0158 min⁻¹ under visible light and full light, respectively. The ternary photocatalyst rGO/COF-C4N/NH2-Bi2O3-5% maintained its performance even after four consecutive cycles, only decreasing by 5% of its degradation rate. The degradation experiments for other chlorophenols pollutants under visible light displayed that this ternary heterojunction is mainly applicable to the degradation of 2-cp and 2, 4-dcp, but inefficient for cp, 3-cp, and 4-cp. The degradation rates of 2, 4-dcp could reach 85.1% under visible light. Based on the analysis of band structure, free radical trapping experiment and photoelectrochemical properties, the photocatalytic degradation mechanism of chlorophenols by type II rGO/COF-C4N/NH2-Bi2O3 heterojunction was proposed, in which h+ and ∙OH- have main influence on the degradation activity, and the rGO plays an important role in improving the charge transfer and separation. This work provides a choice for the effective removal of chlorophenols wastewater by photocatalysis

A Fe-MOFs/rGO/Au ternary composite to construct a competitive electrochemical immunosensor for Hg 2+ . • The porous conductive hybrid accelerates mass transfer and provides abundant antibody binding sites. • The established immunosensor exhibits two linear range of 0.05–200 and 250–2500 nM of Hg 2+ . • The established immunosensor displays the specific selectivity and a low LOD of 0.075 nM. • The sensing platform shows the promising potential for environmental heavy metal monitoring. The development of ultrasensitive Hg 2+ detection in water environments is crucial owing to its severe toxicity to ecosystems and human health. In this work, a label-free competitive electrochemical immunosensor was fabricated for the detection of mercury ions (Hg 2+ ) based on a ternary iron-based metal organic framework/reduced graphene oxide/gold nanoparticles (Fe-MOFs/rGO/AuNPs) nanocomposite. The Fe-MOFs/rGO hybrid composite was synthesized via a hydrothermal strategy, which significantly enhanced the conductivity and effective surface area of the electrode interface. Furthermore, L-cysteine-mediated AuNPs were covalently conjugated to the Fe-MOFs/rGO matrix, which not only offered a stable substrate for the immobilization of anti-Hg 2+ antibodies but also accelerated interfacial electron transport. By monitoring the current response through differential pulse voltammetry (DPV), the immunosensor exhibited the two linear ranges of 0.05–200 nM and 250–2500 nM toward Hg 2+ , accompanied by an ultralow detection limit (LOD) of 0.075 nM. Benefiting from the synergistic effect of the ternary nanocomposite as well as the outstanding specificity of antibody-antigen immunorecognition, the developed immunosensor meets the requirement for the safety monitoring Hg 2+ in complex environmental water samples.

One-pot synthesis of rGO/PEDOT:PSS/Ru composite for targeted flavonoid sensing. • PEDOT:PSS prevents rGO restacking and enables uniform Ru nanoparticle dispersion. • Interfacial coupling downshifts Ru d-band center to accelerate oxidation kinetics. • Ternary architecture greatly minimizes charge-transfer resistance at the interface. Flavonoid quantification is essential for pharmaceutical and food quality control, yet direct electrochemical detection is hindered by sluggish heterogeneous electron-transfer kinetics and limited current responses at trace concentrations on unmodified electrodes. We report an electrochemical sensing platform based on an rGO/PEDOT:PSS/Ru nanocomposite. Structural characterization indicates that π-π stacking between rGO and PEDOT:PSS prevents graphene restacking, enabling uniform Ru nanoparticle distribution. Crucially, interfacial electronic coupling within the ternary network downshifts the d-band center of the Ru nanoparticles, thereby accelerating the electro-oxidation kinetics. Electrochemical kinetic analyses reveal that the analytes undergo an adsorption-controlled, two-electron and two-proton (2e - /2H + ) transfer pathway. This architecture significantly minimizes charge-transfer resistance and expands the electroactive surface area. Differential pulse voltammetry delivered linear ranges of 0.006–65.0 μM (rutin), 0.05–70.0 μM (quercetin), and 0.02–50.0 μM (baicalin), with detection limits of 3.7, 17.3, and 6.3 nM, respectively. The sensor maintained consistent responses over 15 days and exhibited reliable selectivity against common interferents. Recovery studies in Sophora japonica, onion, and Scutellaria baicalensis extracts correlated with UV–Vis reference data, illustrating how coupling conducting polymers with redox-active nanoparticles can modulate interfacial electron-transfer pathways for targeted electrochemical sensing.

For the intrinsic limitations of CoP in alkaline water splitting (irrational electronic structure, poor conductivity, and agglomeration-caused low active site utilization), this work puts forward a bifunctional optimization strategy: "Fe-doping electronic modulation coupled with rGO support synergistic enhancement", and synthesizes the Fe-CoP@rGO composite catalyst (Fe-doped CoP nanoparticles anchored on rGO) via wet-chemical method and phosphidation. The introduction of Fe induces electron rearrangement by substituting Co atoms in CoP lattice significantly increases the proportion of highactivity Co 3+ sites and optimizes the adsorption energy barriers of *H/*OH intermediates. Meanwhile, the high conductivity of rGO constructs an efficient electron transport network, and its large specific surface area inhibits nanoparticle agglomeration through steric hindrance, enhancing the electrochemical active surface area (ECSA) twice that of pure CoP.Bifunctional catalytic performance tests show that Fe-CoP@rGO achieves low overpotentials of 86.2 mV (HER) and 285 mV (OER) at 10 mA cm -2 , which are significantly superior to those of CoP@rGO. When assembled into an overall water splitting device, it only requires 1.61 V to reach 10 mA cm -2 , with no performance degradation after 24 h of continuous operation in 1 M KOH and a Faraday efficiency close to 100%. This study provides a clear structure-activity relationship and a scalable optimization pathway for designing high-performance and stable non-noble metal bifunctional electrocatalysts through the synergistic effect of electronic structure modulation and support function enhancement

A novel electrochemical sensor (NiO/MoS₂/rGO/GCE) designed for the sensitive detection of methyl parathion (MP) pesticide residues has been developed. The NiO/MoS₂/rGO composite was synthesized via hydrothermal and solvothermal methods, with successful formation and optimized microstructural characteristics validated through scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Empirical results demonstrated that the incorporation of NiO markedly augmented both the electrochemically active sites and electron-transfer efficiency, thereby enabling the sensor to achieve an excellent linear detection range of 0.01–10 μg/mL for MP, accompanied by a notably low detection limit of 1.1 ng/mL (S/N = 3). Furthermore, the sensor exhibited superior anti-interference performance, achieving recovery percentages ranging from 97.7 to 108.8% in practical sample analyses (apple juice), with relative standard deviations (RSD) between 2.7 and 5.2%. Overall, this research offers a promising and cost-effective approach for highly sensitive pesticide residue detection, underscoring its substantial potential for broad practical applications.

To date, the fabrication of advanced anode materials that can accommodate both Na+and K+storage is still very challenging. Herein, we developed a facile solvothermal and subsequent annealing process to synthesize SnS2/RGO composite, in which SnS2nanosheets are bonded on RGO, and investigated their potential as anodes for Na+and K+storage. When used as an anode in SIBs, the as-prepared SnS2/RGO displays preeminent performance (581 mAh g−1at 0.5 A g−1after 80 cycles), which is a significant improvement compared with pure SnS2. More encouragingly, SnS2/RGO also exhibits good cycling stability (130 mAh g−1at 0.3 A g−1after 300 cycles) and excellent rate capability (520.8 mAh g−1at 0.05 A g−1and 281.4 mAh g−1at 0.5 A g−1) when used as anode for PIBs. The well-engineered structure not only guarantees the fast electrode reaction kinetics, but also ensures superior pseudocapacitance contribution during repeated cycles, which has been proved by kinetic analysis.

In this paper, a facile route has been developed to prepare magnetic trimetallic Au-Ag-γ-Fe2O3/rGO nanocomposites. The impact of the preparation method (the intensity of reductant) on the catalytic performance was investigated. The nanocomposites were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The prepared nanocomposites show fine catalytic activity towards the reduction reaction of 4-nitrophenol (4-NP). The nanocomposites also have superparamagnetism at room temperature, which can be easily separated from the reaction systems by applying an external magnetic field.

Two-dimensional (2D) nanosheets are promising nanomaterials that can be used as sensing elements in numerous applications such as wearable devices , machine tools, and aircraft; however, challenges remain in achieving high sensitivity, wide frequency sensing range, and reliability after long cyclic loading. Suitable ink formulations and preparation parameters for embedded sensors while retaining the structural integrity of the host structure should be determined. In this work, we demonstrated a synergistic combination of l -cysteine-reduced graphene oxide and MXene (LGM) inks in the absence of an additional polymer matrix to establish noninvasive conditions for embedding sensors in prepreg fiberglass/epoxy for smart composites with sensing capabilities. This sensor offers a high gauge factor of 47–1400 in different tensile strain ranges, with unnoticeable changes in the outstanding mechanical properties of the host glass fiber-reinforced polymer (GFRP) laminate. Long-term fatigue three-point bending tests were performed at different frequencies and bending angles, demonstrating excellent durability and stability. The corresponding sensors can also capture vibration signals in the low-high-frequency ranges. The nonintrusive embedment of sensors in GFRP laminates using the new coated non-additive polymer matrix LGM ink successfully preserves the mechanical properties of the host, including its structural integrity, with outstanding sensing performance for low-to-high-frequency signals.

All-solid-state lithium‑sulfur batteries are becoming a breakthrough technology for energy storage systems due to its high energy density , high safety and low cost of sulfur. However, its application has been restricted by the isolating properties of sulfur (S), as well as S shuttle effect, S volume effect, and low electron conductivity. In this work, the amorphous sulfur-reduced graphene oxide (S/rGO) composite cathode material was prepared with a smaller particle size of about 2 nm S onto rGO to alleviate the volume effect of S (after 30 cycles, the charge transfer impedance changes about only 3 Ω); at the same time, highly conductive rGO maintain good ionic conduction during charge-discharge cycling. Along with the cathode material, we fabricated a composite polymer electrolyte (CPE) based on poly (ethylene oxide), lithium-ion conductor Li 6.4 Ga 0.2 La 3 Zr 2 O 12 -succinonitrile (PEO 18 - LiTFSI-LLZO-SN) possessing lithium conductivities of 1.16 × 10 −4 and 7.26 × 10 −4 S cm −1 at room temperature and 60 °C, respectively, which can mitigate the transport of polysulfide and be suitable for battery applications. The composite cathode material exhibits an initial discharge capacity of 783mAh g −1 at 45 °C, with a capacity retention rate of 81.2% at 0.2C after 60 cycles. At 60 °C, the battery shows excellent electrochemical cyclability 820mAh g −1 of reserved capacity after stable operation for 100 cycles at 0.2C. The synergy between the CPE and the amorphous S/rGO composite cathode demonstrated in this work may bring insights to improve the cycling performance of all-solid-state Li-S batteries

MOF-derived Fe-doped Ni 9 S 8 nanoparticles are uniformly anchored on N-rGO. • The synergistic effect at the heterointerface enhances electron transfer and active site exposure. • Fe 0.1 -Ni 9 S 8 /N-rGO achieves an overpotential of 255 mV at 50 mA cm −2 . • Fe doping shifts the d-band center down, weakening *O adsorption and lowering the RDS barrier. Developing effective, low-cost oxygen-evolution catalysts is essential for sustainable energy technologies. Here, we synthesized an N-doped reduced graphene oxide-supported, Fe-doped Ni 9 S 8 catalyst (Fe 0.1 -Ni 9 S 8 /N-rGO) by MOF-derived pyrolysis followed by sulfidation. To separate the effects of Fe-induced electronic modulation from N-rGO–assisted interfacial engineering, we prepared a series of control samples: Ni 9 S 8 , Ni 9 S 8 /N-rGO, Fe 0.1 -Ni 9 S 8 , and Fe 0.1 -Ni 9 S 8 /N-rGO. The optimized Fe 0.1 -Ni 9 S 8 /N-rGO exhibited efficient OER electrocatalysis, delivering 50 mA cm −2 at an overpotential of 255 mV with a Tafel slope of 54.58 mV dec −1 . Synergistic Fe doping and the Ni 9 S 8 /N-rGO heterojunction enhanced conductivity and increased active-site exposure, yielding higher activity. Electronic-structure analysis showed that Fe doping shifts the d-band center and tunes the interaction strength with key OER intermediates, which lowered the energy required for oxygen evolution. This work presents a logical strategy for designing high-performance, nonprecious-metal OER catalysts.

Anisotropic TOCNF/rGO/BaFe 12 O 19 aerogels were fabricated via a simple FESTA strategy. • The anisotropic porous architecture promotes multiple reflection and scattering of EMWs. • BaFe 12 O 19 introduction enables synergistic dielectric-magnetic loss mechanisms. • A minimum reflection loss of −62.19 dB and a bandwidth of 8.91 GHz were achieved. • CST simulations confirm the excellent EMW attenuation capability. Leveraging its ultralight weight and well-developed porous structure, three-dimensional graphene aerogel demonstrates exceptional application value in electromagnetic wave absorption. Nevertheless, achieving synergistically enhanced absorption performance through simultaneous structural engineering and multi-loss mechanism integration remains a formidable challenge for lightweight graphene-based aerogels. In this work, anisotropic TOCNF/rGO/BaFe 12 O 19 aerogels were fabricated via a freezing-ethanol solvent exchange thawing and ambient drying (FESTA) strategy. By incorporating BaFe 12 O 19 , the cooperative enhancement of dielectric and magnetic losses was achieved, while the unique porous architecture promoted successive reflections and scattering of incident electromagnetic waves (EMWs) within the aerogel, thereby facilitating electromagnetic energy dissipation. With the rGO/BaFe 12 O 19 mass ratio adjusted to 1:1, the resulting aerogel achieved an RL min of −62.19 dB and an EAB of 8.91 GHz. The superior EMW absorption performance stems from the enhanced polarization and magnetic losses. Radar cross-section (RCS) analyses moreover reveal that the aerogel possesses favorable electromagnetic wave scattering suppression performance under realistic conditions. Therefore, this study offers a viable approach for realizing electromagnetic absorbing materials integrating light weight, broad bandwidth, and excellent performance.
