Photocatalytic uranium recovery from water bodies is
hindered by
the poor pH stability and low photocarrier separation efficiency of
conventional photocatalysts. Herein, we constructed a recyclable rGO/g-C 3 N 4 aerogel with a Schottky junction that simultaneously
addressed both limitations. The optimized rGO/g-C 3 N 4 -2 exhibited pH-insensitive performance (pH 2.0–9.0).
Furthermore, the Schottky barrier directs unidirectional electron
migration toward rGO under illumination, boosting charge separation
efficiency to 78.5%. These Schottky-junction-enabled charge dynamics,
large specific surface area, the layered structure that facilitated
mass and electron transport, and the favorable negative surface charge
for UO 2 2+ enrichment collectively contributed
to the photocatalytic performance. Consequently, rGO/g-C 3 N 4 -2 demonstrated a 92.9% uranium extraction efficiency
within 120 min and maintained high efficiency even after 5 cycles
under visible light. DFT calculations revealed band gap narrowing
to 1.65 eV (vs 2.20 eV for pristine g-C 3 N 4 ),
thereby increasing the light utilization rate. In situ DRIFTS spectroscopy revealed the evolution pathway of active species
from • O 2 – to H 2 O 2 . Combined with XPS and XRD analysis, the transformation
of U(VI) into (UO 2 )O 2 ·2H 2 O after
photocatalytic uranium extraction was confirmed. This study presents
a pH-tolerant and recyclable photocatalyst with a Schottky junction
for uranium extraction from complex aqueous environments, offering
a viable strategy for sustainable nuclear fuel cycles.

A green one-pot in-situ strategy constructs multifunctional MnP@rGO. • EP/4MnP@rGO achieves UL-94 V-0 rating with LOI of 29.5%. • PHRR and TSR are reduced by 40.2% and 49.7%, respectively. • Impact strength (+27.8%) and thermal conductivity (+284.2%) enhanced. • Excellent solar absorptance enables rapid photothermal de-icing. The intrinsic conflicts among mechanical robustness, fire resistance, and thermal functionality severely hinder epoxy resins (EP) in advanced applications. Conventional single-additive strategies inevitably compromise mechanical integrity and fail to address photothermal de-icing demands. Herein, we circumvent these limitations via a green one-pot in-situ reduction strategy that constructs a multifunctional manganese aminotrimethylene phosphonate@reduced graphene oxide (MnP@rGO) heterostructure without external reducing agents. This hybrid architecture exploits dual synergies, where the rGO scaffold ensures robust interfacial load transfer and physical barrier effects, while Mn 2+ centers serve as Lewis acid catalysts to promote cross-linking and graphitization of the degrading matrix into a protective char layer. At 4.0 wt% loading, the EP/MnP@rGO nanocomposite achieves a 27.8% enhancement in impact toughness and a 24.9% increase in tensile strength, alongside a UL-94 V-0 rating with 49.7% suppression in total smoke release and 46.4% reduction in total heat release. Moreover, the tailored interfacial structure imparts outstanding photothermal conversion efficiency, enabling rapid surface heating and reliable de-icing. This work establishes a transformative paradigm for converting an inherently compromised thermoset into an integrated multifunctional platform for protective coatings in icing-prone infrastructures such as wind turbine blades and aerospace composites.

This study featured about the synthesis of graphene oxide hydrogel-CuO@reduced graphene oxide (rGH-CuO@rGO) micromotors with core-shell structure via an ultrasonication-assisted chemical precipitation method and their application for catalytic dye degradation. The micromotors were comprehensively characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), spectroscopic techniques (Fourier transform infrared (FTIR), Raman), surface area measurement (BET), and X-ray photoelectron spectroscopy (XPS) to determine their microstructure, composition, and chemical states. Degradation performance for methylene blue (MB) was evaluated under varying conditions: reaction time (0–120 min), peroxymonosulfate (PMS) concentration (0–5 g·L −1 ), pH (3–8), quantity of micromotors (12–24), and MB concentration (5–100 mg·L −1 ). The removal rate of MB was achieved over 90 % within 120 min at pH 8. The micromotors demonstrated excellent catalytic efficiency, reusability and stability over four cycles. In the dual oxidant system (H₂O₂/PMS) the micromotors exhibited effective self-propulsion and stable MB removal. The generation of hydroxyl (•OH) and sulfate (•SO₄ − ) free radicals in the system was confirmed by electron paramagnetic resonance spectrometer (EPR). Ultra High Performance Liquid Chromatography Quadrupole Time-of-Flight Mass Spectrometry (UHPLC-QTOF/MS) was used to identify the degradation intermediates, and the possible MB degradation pathways were proposed. Moreover, the micromotors showed satisfactory performance in removing mixed dye wastewater and phenolic compound. Additionally, the low ecotoxicity of the micromotors was demonstrated by cytotoxicity assessment. This study provided a novel and valuable route to synthesizing self-driving micromotors with potential extensive applications in environmental remediation.

The crystallinity and surface morphology were analyzed using XRD and SEM, and the BET study confirmed a specific surface area of 314 m 2 /g. Electrochemical testing showed that BiCo-MOF@NiO/PANI/rGO (B2) delivered a high specific capacity (Qs) of 431.66 mAh g −1 at 1.5 A g −1 , which is significantly greater than that of BiCo-MOF@NiO (100.08 mAh g −1 ) and BiCo-MOF@NiO/PANI (242.95 mAh g −1 ). Under a two-electrode asymmetric configuration, the device attained a Qₛ of 132.37 F/g at 0.7 A/g and maintained 83.3 % capacity after 10,000 cycles.

Extracorporeal membrane oxygenation (ECMO) is a life-saving technology for patients with severe cardiopulmonary failure. However, bleeding complications remain a major clinical challenge, largely due to high shear stress-induced Von Willebrand factor (VWF) dysfunction. Existing methods often lack timeliness and sensitivity for VWF detection in early bleeding risk assessment. Here, we proposed an electrochemical biosensor that combined Two-Step Synthesized graphene oxide-gold nanoparticles (rGO@AuNPs) nanocomposites modified screen-printed electrodes and a miniaturized wireless communication circuit for point-of-care testing (POCT) of VWF levels. The introduction of rGO@AuNPs significantly enhanced the sensing performance, achieving a low limit of detection of 0.39 pg/mL for VWF within 15 min. Moreover, there are Pearson correlation coefficients of 0.926 and 0.974 between the VWF biosensor and ELISA for porcine models and clinical samples. Notably, VWF degradation was associated with high shear stress, and VWF depletion was observed at the same time of APTT prolongation, suggesting its utility as a biomarker for bleeding risk. Its rapid, portable, and cost-effective design supports POCT, offering a promising tool for early monitoring and intervention in ECMO-related bleeding.

Aqueous Zn//MnO 2 batteries have attracted much attention for their promising application in large-scale energy storage and flexible electronics. However, it is an obstacle to develop high-performance MnO 2 that can be massively synthesized via a facile method. Herein, a mechanical grinding method is employed to prepare α -MnO 2 /reduced graphene oxide ( α -MnO 2 /rGO) composite material in which α -MnO 2 nanofibers are uniformly loaded onto the surface of rGO sheets. It is found that the α -MnO 2 /rGO composite cathode exhibits much superior rate performance and cycling stability over α -MnO 2 , which is attributed to the significantly increased electrical conductivity and enlarged specific surface area. In addition, a flexible quasi-solid-state Zn// α -MnO 2 /rGO battery with excellent cycling performance was fabricated, and can survive multiple damages. This work provides a guidance to the massive production of high-performance cathode materials for aqueous zinc-ion batteries.

Combining flexible reduced graphene oxide (rGO) with highlyelectrical conductive and flame retardant MXene to prepare electromagnetic interference (EMI) shielding composite film is a research hotspot. In this work, with a small amount of polyvinyl alcohol (PVA) used as the adhesive, rGO/MXene loaded on spunlace non-woven fabric (SNF) through a soaking-drying-reduction method to form a sandwich structure composite film (SNF covered with rGO/MXene nanosheets as the interlayer, and rGO/MXene thin films as the upper and lower layers). The related EMI shielding effectiveness (SE), electric heating performance and flame retardancy of the fabricated sandwich structure composite film have been investigated. When the mass ratio of rGO to MXene is 6:4 (named rGO/MXene-4), the average SE T of the film can reach 55.81 dB in X-band with an absorption-dominant shielding. Applying a 4 V voltage to rGO/MXene-4 film, its surface temperature can exceed 110 °C within 10 s, which indicated the fabricated rGO/MXene-4 film can be applied as a high electromagnetic shielding electric heating device with outstanding flame retardancy.

High-quality film capacitors are widely used in many fields such as new energy vehicles, electronic communications, etc., due to their advantages in wide frequency response and low dielectric loss. The dielectric film is a crucial part of the film capacitor, and its properties have an important impact on the performance and use conditions of the film capacitor. In this work, a novel high-temperature-resistant dielectric film was prepared. Firstly, the Bi 2 S 3 /rGO-CN fillers were prepared by hydrothermal method combined with cyanation treatment, and then added to the poly(arylene ether nitrile) (PEN) matrix to prepare the dielectric film materials (PEN/Bi 2 S 3 /rGO-CN). After high temperature treatment, the fillers Bi 2 S 3 /rGO-CN reacted with the PEN matrix, and the composites materials transformed into a thermosetting hybrid film (PEN-Bi 2 S 3 /rGO) with gel content of 97.88%. The prepared hybrid dielectric films did not decompose significantly before 400 °C, and showed a glass transition temperature ( T g ) of up to 252.4 °C, which could increase the effective use temperature of the materials. Compared with the composite films without heat treatment, they exhibit better mechanical properties, with further improvement in tensile strength and elastic modulus, and a decrease in elongation at break. The dielectric constant of the hybrid films can be up to 6.8 while the dielectric loss is only about 0.02 at 1 kHz. Moreover, the hybrid films showed excellent dielectric stability during temperature changes, and remain relatively stable before 250 °C, which is suitable as a high-temperature-resistant high-dielectric material and is more advantageous for practical applications.

Ciprofloxacin (CIP) is a third-generation fluoroquinolones (FQs) antibiotic, and the occurrence of CIP in the water environment has raised growing concerns owning to its environmental toxicity. In this paper, a novel α-(Fe, Cu)OOH/RGO nanocomposite was synthesized via a one-step reflux method for CIP degradation through a photo-Fenton-like process. When the RGO content was 1 wt%, CIP degradation ratio by the α-(Fe, Cu)OOH/RGO nanocomposite reached 100% under visible light irradiation within 120 min, and total organic carbon (TOC) removal ratio reached 60% within 180 min. The result of molecular fluorescence spectra highlighted that the loading of RGO on the α-(Fe, Cu)OOH significantly increased the content of hydroxyl radicals (·OH) in the heterogeneous photo-Fenton-like system and simultaneously inhibited the recombination of photogenerated electron and hole, which played critical roles in the enhancement of CIP degradation. In addition, 11 main intermediates were identified as the degradation products of CIP in the α-(Fe, Cu)OOH/RGO/H 2 O 2 /visible light reaction systems using liquid chromatograph–mass spectrometer (LC-MS) analyses. The results demonstrated that three degradation pathways for CIP removal by α-(Fe, Cu)OOH/RGO nanocomposite occurred, including (i) oxidation on the piperazine ring and dealkylation, (ii) defluorination and decarboxylation, and (iii) hydroxylation on the quinolone ring. This work would provide a novel insight of CIP degradation pathways in photo-Fenton-like processes. Graphical abstract

Photocatalytic CO 2 reduction has been considered as a potential way to solve the energy problem and the greenhouse effect. In this work, layered g-C 3 N 4 /rGO/NiAl-LDHs heterojunctions were prepared by using a hydrothermal method, the optimized composite exhibited enhanced photocatalytic CO 2 reduction to CO (2.6 μmol h −1 g −1 ) and CH 4 (20 μmol h −1 g −1 ) activity, which was 3.7 and 14.2 times higher than that of pure g-C 3 N 4 , respectively. According to the experimental and density functional theory calculation (DFT) results, it is believed that with the large contact interface and excellent electron mobility rGO could act as an electron transfer bridge to facilitate the rapid charge migration and separation between g-C 3 N 4 and NiAl-LDHs. Thus, driven by the internal electric field, interfacial band edge bending, as well as the type II heterostructure, the activity of g-C 3 N 4 /rGO/NiAl-LDHs could be greatly enhanced. This work provides a possible way to rational design and fabrication of rGO-assisted composite systems with type II, Schottky, S-scheme, P-N and other heterojunctions.

Although lightweight and three-dimensional (3D) graphene aerogels are highly desirable for microwave absorption (MA) due to their high porosity, specific surface area, and 3D conductive network, it still remains a large challenge to construct a multifunctional application framework to quickly adapt to the complex practical environment, making it to be efficiently applied in a variety of complex situation. Herein, multifunctional aramid nanofibers (ANFs) reinforced reduced graphene oxide aerogels (RGO@ANF) have been achieved by in-situ gel reaction, freeze-drying, and thermal annealing processes. The introduced ANFs in RGO aerogels can prevent the graphene sheets from over-stacking and enhance the connectivity of cell walls, thus leading to excellent compression resistance, MA, sound absorption, and thermal insulation performance. Under 70% strain, the maximum compressive stress of RGO@ANF aerogel reaches 78.8 kPa, and reversible compressibility with reliable resistance to fatigue for 100 compressive cycles at 20% strain. Further, the RGO@ANF aerogel exhibit a minimum reflection loss (RL min ) of –56.5 dB and a maximum effective absorption bandwidth (EAB) of 7.0 GHz at a thickness of 2.8 mm, basically covering the X and Ku bands. Moreover, the hybrid aerogel exhibited excellent sound absorption with an average absorption coefficient > 0.56 at 2-6 kHz and good thermal insulation performance with low thermal conductivity of about 49.18 mW m –1 K –1 . The integrated graphene aerogels with such multifunctional performances hold a great promise for applications such as MA, sound absorption, and heat insulation.

In this paper, we investigated the effect of Iron carbide-nitride/reduced graphene oxide composites (FeC x N y /rGO) as catalysts on the thermal decomposition of energetic molecular perovskite (H 2 dabco)[M(ClO 4 ) 3 ] (DAPs, M = Na + , K + and NH 4 + for DAP-1, -2, and -4). FeC x N y /rGO were fabricated by two-step method combined with chemical synthesis and sinter technology of Prussian blue/reduced graphene oxide (PB/rGO). The morphology and structure of FeC x N y /rGO were characterized. The thermal decomposition performance of DAPs with FeC x N y /rGO catalyzed were studied. Results showed that FeC x N y particles with mainly Fe–C and Fe–N bonds involved were located at the surface of rGO nanosheets , the peak thermal decomposition temperature and the apparent activation energy of DAPs were both significantly decreased in the presence of FeC x N y /rGO. Among them, with 5 wt% FeC x N y /rGO-2 added, the peak temperature of DAP-1, DAP-2, and DAP-4 have been decreased by 104.8 °C, 110 °C and 102.2 °C, respectively. Their apparent activation energy decreased significantly by 4.0 kJ/mol, 74.9 kJ/mol and 66.9 kJ/mol, respectively. A possibly thermal catalysis decomposition mechanism was provided. This work provides a new idea for design and fabrication of multifunctional catalysts to enhance the thermal decomposition of energetic molecular perovskite and offers the possibility of applying DAPs to rocket solid propellant .
