● Highly dispersed Co 2 P anchored onto PEI-stabilized N-rGO layers. ● Gas production rate of 517 mL g −1 h −1 with 100% H 2 selectivity. ● Uniform heterointerface with highly accessible interfacial sites. ● Energy barrier reduction by optimized electronic modulation of interfacial Co δ+ . Heterointerface engineering is an effective strategy for constructing strong metal–support interactions and regulating the electronic structure of metal active centers. In this study, the two-dimensional (2D) architecture of N-doped reduced graphene oxide (N-rGO) was employed to construct a uniform and highly accessible heterointerface with Co 2 P nanoparticles, thereby optimizing the electronic structure of Co 2 P for efficient hydrogen production from liquid-phase formic acid (FA). Specifically, polyethyleneimine (PEI) was introduced to stabilize the layered structure of rGO during calcination by intercalating between GO sheets, along with interacting with functional groups on GO via electrostatic interactions and hydrogen bonding. Meanwhile, PEI served as a nitrogen source to promote N doping of rGO and increase effective anchoring sites, such as pyridinic N. The resulting Co 2 P@N-rGO (PEI&phen) catalyst simultaneously achieved high Co 2 P dispersion, exposed interfacial sites, and efficient electron transfer, thereby exhibiting excellent FA dehydrogenation activity with a gas generation rate of 517 mL g −1 h −1 and H 2 selectivity of 100%. This activity was significantly higher than that of the PEI-free counterpart, in which the N-rGO structure was severely damaged, and also exceeded the activities reported for some noble-metal catalysts (e.g., Pd/C, Pt/C) and single-atom cobalt catalysts. XPS characterization and density functional theory (DFT) calculations demonstrated that the abundant Co–N interfacial sites in Co 2 P@N-rGO (PEI&phen) induced interfacial charge redistribution and optimized the electronic structure of Co 2 P species. In situ DRIFTS and DFT calculations confirmed that FA dehydrogenation over this catalyst proceeded through a formate (HCOO*) pathway, while the construction of the Co 2 P/N-rGO heterointerface significantly lowered the energy barrier of the key reaction step, thereby enhancing the catalytic activity.

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.

Frequency selective surfaces (FSSs) are critical for modern defense and wearable electronics due to their thin thickness and precise tunability. However, conventional rigid FSSs lack conformality to complex targets, while emerging flexible film-based alternatives often suffer from insufficient mechanical durability and poor wearing comfort. To address these limitations, this study presents a novel strategy for constructing programmable textile-based quasi-FSSs (q-FSSs) by exploiting the spatial configuration of functional single fibers. Initially, core-sheath silk/reduced graphene oxide (S/rGO) fibers with a low linear density of 50 tex (g/km) were fabricated via converging-flow coaxial wet spinning. These fibers exhibit strong orientation-dependent electromagnetic properties, achieving a minimum reflection loss ( RL min ) of -64.03 dB when aligned parallel to the incident electric field. Leveraging the equivalent circuit model, fiber anisotropy was translated into programmable quasi-frequency selective surfaces via embroidery-based patterning, enabling the design of cross-, rhombus-, and square-patterned unit cells. These spatial geometries distinctly modulated current distribution and resonant behavior, allowing independent tuning of equivalent capacitance and inductance. As a result, their resonant absorption peaks are tailored to 11.88, 8.26, and 8.22 GHz, respectively. Notably, the cross-patterned q-FSS achieved high-efficiency microwave absorption with a lightweight areal density (176.3 g/m2), small-thickness (1.89 mm), strong (-64.24 dB), and broadband (4.2 GHz), surpassing similar MAMs. This work provides theoretical insights into the relationship between fiber spatial configuration and microwave absorption performance, offering a promising pathway for the development of next-generation flexible electronic and stealth technologies.

A Z-scheme CIS/rGO/p-CN heterostructure was designed. • CIS/rGO/p-CN exhibits the highest visible-light activity for Cr(VI) photoreduction. • rGO serves as the solid-state electron mediator to switch the charge transfer mode. Hexavalent chromium (Cr (VI)), a highly toxic metal ion readily soluble in aqueous environments, poses significant threats to human health. Herein, a novel Z-scheme CuInS 2 /rGO/protonated g-C 3 N 4 heterostructure was designed with rGO serving as the solid-state electron mediator between CuInS 2 and protonated C 3 N 4 . The samples were systematically characterized using XRD, FTIR, SEM, TEM, XPS, PL, and UV–vis spectroscopy techniques. This flower-like hierarchical structure CuInS 2 /rGO/protonated g-C 3 N 4 exhibits enhanced visible-light photocatalytic activity for Cr (VI) photoreduction. Specifically, it demonstrates a 98% reductive efficiency for Cr (VI) within 20 min at pH= 4 and stable photocatalytic performance. The results indicate that the integration of rGO nanosheets significantly enhances the photocatalytic performance of the CuInS 2 /rGO/protonated g-C 3 N 4 heterostructure by weakening the built-in electric field between CuInS 2 and protonated C 3 N 4 and switching the charge transfer mode from a conventional p-n junction to a Z-scheme mechanism.

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.

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.

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.

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.

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

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.
