In the work, the layered TiO 2 NS/UiO-66/GO composites were successfully prepared through an in-situ method. Two-dimensional TiO 2 NS combined with UiO-66/GO to form a layered structure. The prepared samples were characterized by X-ray diffraction, thermogravimetric analysis, Brunauer–Emmett–Teller test, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, UV–Vis DRS and PL spectra. TiO 2 NS/40%UiO-66/GO exhibited the most efficient adsorption (20 and 1.3 times those of TiO 2 NS and UiO-66/GO, respectively) through absorbing Congo red (CR). It also displayed the strongest photocatalytic activity (29 and 2 times those of TiO 2 NS and UiO-66/GO, respectively) for degrading CR dye under visible-light irradiation (λ ≥ 420 nm). The removal rate of CR was nearly 100%. Besides, TiO 2 NS/40%UiO-66/GO showed excellent stability even after four cycling runs of adsorbing and photodegrading CR. The results showed that TiO 2 NS/UiO-66/GO composites were highly efficient adsorption and catalytic bifunctional materials. TiO 2 NS/UiO-66/GO composites provide an important basis for combining metal organic frameworks/GO with photocatalytic semiconductors to improve absorption and photocatalytic performance to better treat organic wastewaters.

Mixed valent iron ions were used to create a flexible ionic crosslinking network through coordination, making PAA fiber highly stretchable, and the fiber was highly stretched to tear graphene oxide (GO) sheets into discontinuously-dispersed monolayer sheets. The monolayer sheets could construct many hydrogen bonds with PAA chains to serve as knots to hinder chain movement, controlling the shrinkage of stretched fiber. Co-solvent formamide could improve the heat resistance of PAA fiber through special calorific effect; thus the highly-stretched fiber could tolerate high temperature heat setting. Due to the advanced structure induced by stretching, internal force relaxation caused by heat setting, and the existence of knots, the resulting fiber possessed the features of high strength and no shrinkage. High strength made the fiber mechanically applicable, and the unshrinkability could help it to maintain large specific surface area and strong iron ions-immobilizing capability. As a result, the catalytic activity of non-shrinkable fiber was increased by 25% compared with that of shrinkable fiber for methylene blue (MB) decolorization, and iron ion loading ratio was increased by 174.5%; however, iron ion leaching ratio was decreased by 76.5%, which was conducive to reusability improvement. Thereby, the resulting fiber could be repeatedly used to decolorize MB.

Developing multifunctional electrode materials that integrate high energy storage capacity with catalytic activity is essential for next-generation energy systems. Herein, a hierarchically engineered NiSnSe₂@r-GO@Ni-MOF composite was synthesized by the use of a two-step hydrothermal process, combining the high conductivity of r-GO, the porous framework of Ni-MOF, and the redox activity of NiSnSe₂. Structural and morphological investigations (SEM, XRD, Raman, XPS, and BET–BJH) confirmed the formation of a well-integrated mesoporous architecture with a large available electroactive sites and effective electron–ion transport. Electrochemical evaluation exhibited a high specific capacity of 1297.8 C g⁻¹. The assembled asymmetric device (NiSnSe₂@r-GO@Ni-MOF//AC) achieved an energy density of 44.8 Wh kg⁻¹ and a power density of 1120 W kg⁻¹, with 90% capacity retention over 7,000 cycles. Additionally, the composite exhibited excellent HER response and delivered a low overpotential of 49 mV and a Tafel slope of 52 mV dec⁻¹. The boosted bifunctional enactment is accredited to strong interfacial coupling and stabilizes the electrode structure, which highlights a scalable strategy for designing efficient multifunctional heterostructure to overcome the energy crisis in the present era.

BNNS/GO/PVA hybrid aerogel with 3D anisotropic network is fabricated by ice-templating. • HGBP/PW composite achieves 91.17% PW loading and 197.8 J/g melting enthalpy with 121.83% enthalpy efficiency. • Vertical thermal conductivity of HGBP5/PW is enhanced by 360% to 1.15 W/(m·K) vs pure PW. • HGBP5/PW realizes 97.80% photothermal conversion efficiency and 228.9 mV photo-thermal-electric output voltage. • HGBP/PW composite exhibits excellent shape stability and robust cycling durability with negligible leakage. Phase change materials (PCMs) are promising for solar thermal energy storage but suffer from leakage, low light absorption and thermal conductivity. Herein, a shape-stabilized composite PCM (HGBP/PW) was prepared by encapsulating paraffin wax (PW) into a BNNS/GO/PVA hybrid aerogel via ice-templating and vacuum impregnation. The 3D anisotropic network is constructed with GO as framework and photo-thermal absorber, BNNS for thermal conduction, and PVA as mechanical support. HGBP/PW exhibits 91.17% PW loading, a melting enthalpy of 197.8 J/g and 121.83% enthalpy efficiency. Its vertical thermal conductivity reaches 1.15 W/m·K, 360% higher than pure PW. It reduces LED chip temperature by 46.41%, shows 97.8% photo-thermal conversion efficiency and excellent cycling stability. Efficient solar-thermal-electric conversion is also achieved under simulated and natural sunlight, with a maximum output voltage of 228.9 mV and maintaining a reliable 118.2 mV output. This work offers a scalable strategy for multifunctional PCMs toward thermal management and efficient solar energy utilization.

The efficiency and longevity of photovoltaic (PV) panels are significantly impaired by excessive operational heat accumulation, which can reduce electrical efficiency by 0.4–0.5% per °C above 25°C and lead to 20–30% annual energy losses in urban environments. This study presents an innovative passive thermal management system integrating a three-dimensional oscillating heat pipe (3D-OHP) with hybrid graphene oxide (GO)–MXene (Ti 3 C 2 T x ) nanofluids at concentrations of 0.1 wt% and 0.2 wt%, leveraging GO’s high thermal conductivity (up to 3000 W/m.K) and MXene’s low viscosity and hydrophilicity for enhanced heat transfer and stability. Experiments conducted in Mashhad, Iran, under solar irradiances of 660–1090 W/m 2 , demonstrate that the 0.2 wt% GO-MXene nanofluid reduces thermal resistance by 41.1% (compared to 35.6% for MXene and 28.2% for GO alone), lowers panel temperature by over 24°C (versus 21.2°C for MXene, 15.4°C for GO, and 6.3°C for water), and boosts electrical power output by 14.9% (peaking at 48.3 W versus 42.1 W for the uncooled panel). This results in an additional 43 W/day of electricity generation, outperforming MXene (38.4 W/day), GO (27.3 W/day), and water (16.8 W/day) coolants. First-law electrical efficiency improves to 11.51% (from 10.02% uncooled), while peak exergy efficiency reaches 30.9% (versus 27.4% for MXene, 24.6% for GO, and 22.1% for water). Thermophysical enhancements include a 6% increase in thermal conductivity (to 0.651 W/m.K) with only a 31% viscosity rise (to 1.17 mPa.s), supported by zeta potentials exceeding ± 30 mV for stability. Economic evaluation yields a Levelized Cost of Energy (LCOE) of 0.083 USD/kWh and Levelized Cost of Storage (LCOS) of 0.273 USD/kWh for GO-MXene, balancing superior performance with affordability compared to water (LCOE: 0.071 USD/kWh; LCOS: 0.09 USD/kWh) and other nanofluids (GO LCOE: 0.086 USD/kWh; MXene LCOE: 0.080 USD/kWh). This scalable, surfactant-free system advances sustainable urban solar technologies by mitigating thermal stress, enhancing efficiency, and supporting net-zero energy goals with minimal environmental impact.

Nanofiltration (NF) membranes face the persistent challenge of fouling, which severely curtails their operational lifespan and efficiency in water treatment. In this study, a novel photocatalytic composite polyester (PE) nanofiltration membrane was fabricated to address this bottleneck by integrating a Co-doped CuFe 2 O 4 @GO (Co/CFO@GO) interlayer with a glucose-based selective layer. Unlike traditional polyamide membranes, a green and cost-effective glucose monomer was utilized to react with trimesoyl chloride (TMC) via interfacial polymerization (IP), forming a robust cross-linked polyester network. The Co/CFO@GO interlayer not only modulated the diffusion kinetics of the aqueous monomer to optimize the membrane pore structure (mean pore size ~0.631 nm) but also endowed the membrane with advanced photocatalytic self-cleaning capabilities. Under simulated solar irradiation, the embedded catalyst facilitated the generation of reactive oxygen species (ROS), enabling the rapid mineralization of entrapped organic foulants (Rhodamine B, RhB). The resultant composite membrane demonstrated an excellent flux recovery ratio (FRR > 97%) after three fouling-cleaning cycles. Furthermore, the membrane exhibited exceptional stability during long-term continuous filtration tests. This work provides a sustainable paradigm for developing antifouling polyester NF membranes with in-situ self-cleaning functionality for complex wastewater remediation.

In this paper, a novel nanocomposite fulvic acid reduced graphene oxide (FA-rGO) and Co-phthalocyanine nanorods (CoPcNRs) was prepared and used to construct an electrochemical sensor for simultaneous detection of catechol (CC), hydroquinone (HQ), phenol (PN) and p-nitrophenol (p-NP). FA as reductant used to prepare FA-rGO nanocomposite, which fabricated by hydrothermal method and freeze-drying process. The method is environmentally friendly and realizes the gentle reduction of GO. CoPcNRs were synthesized by surfactant-assisted ultrasonic method. The microstructure and morphologies of the as-prepared materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and UV-Vis spectrophotometer. The electrochemical oxidation of CC, HQ, PN and p-NP was investigated using differential pulse voltammetry (DPV). The results show that the FA-rGO/CoPcNRs modified electrode exhibits excellent electrochemical activity toward the simultaneous redox of CC, HQ, PN and p-NP. Under optimal conditions, the linear ranges of CC, HQ, PN and p-NP were 1 μM–650 μM, 2 μM–450 μM, 2 μM–160 μM, 2 μM–140 μM, with 0.3 μM, 0.65 μM, 0.65 μM and 0.65 μM, respectively. In addition, the modified electrode showed good selectivity, sensitivity and stability. The application in real samples was also evaluated, and the recoveries suggesting that FA-rGO/CoPcNRs nanocomposites could be used as an excellent potential reaction platform for the simultaneous determination of CC, HQ, PN and p-NP in environmental samples.

Conventional metal–organic frameworks (MOFs) used for electrocatalytic applications have the drawbacks of poor conductivity and instability. Herein, a Cu–1,2,3,4,5,6-benzenehexamine (Cu-HAB)/graphene oxide (GO) composite was prepared for the electrocatalytic degradation of tetracycline hydrochloride (TCH). Our characterization results show that Cu-HAB/GO has more active sites ( I D / I G = 1.0030), larger surface area (S BET = 395.3441 m 2 /g), and faster electron transport (Rct = 20.69) than Cu-HAB. Simultaneously, the improvement in the number of active sites, surface area and electron transport leads to a superior TCH electrocatalytic degradation efficiency. The reaction rate constant (0.70575 min −1 ) of the composite was higher with a 51.81% improvement observed when compared to Cu-HAB under the optimum conditions of 1 g/L NaCl, 20 mA, and 20 °C. In addition, 100% of the degradation efficiency was maintained after five cycles. A detailed study of the mechanism revealed that 1 O 2 and active chlorine were the critical active species for the degradation of TCH via quenching and electron paramagnetic resonance (EPR) studies. The possible TCH degradation pathway has been proposed. This study provides a novel and feasible method for the preparation of MOF-based electrocatalysts to expand their application to environmental fields.

The removal of heavy metal ions from the aqueous environment is an important topic as heavy metal pollution is widely distributed in water bodies, causing serious damage to aquatic ecosystems and worsening the already scarce freshwater resources. In this work, we report the synthesis of novel ZIF-8@GO-COOH composite nanosorbent materials by in situ self-assembly. The physicochemical properties of the composites were investigated using relevant characterisation techniques, and the adsorption capacity of ZIF-8@GO-COOH for copper and lead ions in aqueous solution was tested by batch adsorption experiments. The adsorption behaviour was analysed by combining adsorption kinetics, adsorption isotherm model and Van't Hoff model. The results showed that the adsorption capacities of ZIF-8@GO-COOH for Cu(II) and Pb(II) were 93.26 mg/g and 95.875 mg/g, respectively, when the initial heavy metal ion concentration was 100 mg/L, the adsorption time was 60 min, the temperature was 293 K and the pH conditions were suitable. The high adsorption performance of ZIF-8@GO-COOH was attributed to its surface with abundant oxygen-containing functional groups and excellent specific surface area, which gives it a significant advantage in the removal of heavy metal ions from aqueous solutions.

Graphene oxide lamellar 2D membranes are widely researched for ion separation and molecular sieving in aqueous solution. Extension of the research of GO-based membranes for organic solvent nanofiltration has drawn much attention but is still in its infancy. The relatively low solvent permeability remains a difficult problem to overcome. Inspired by the shell of the Namib Desert beetle, a heterostructured lamellar membrane was prepared by incorporating MoS 2 quantum dots (MQDs) into the graphene oxide membrane. A dual-functional zone was formed, where hydrophilic areas exhibited excellent absorption performance for polar solvents and hydrophobic regions were propitious to the discharge of polar solvents when incorporating a moderate amount (10%) MQDs, denoted as GM-10 (nonpolar solvents presented the opposite performance). The synergistic effects of the dual-functional zone successfully improved the transport efficiency for various solvents, and the flux of various solvents for GM-10 was over three times higher than that of the pure GO membrane. Simultaneously, the composite biomimetic membrane showed excellent stability. This paper provides a novel strategy for constructing a heterostructured dual-functional zone for 2D lamellar membrane modification without the sacrifice of rejection, revealing the potential for further optimization of separation performance and membrane stability.

A composite PW 4 @UIO-66-NH 2 /GO was designed and prepared via facile in-situ synthesis method for catalytic oxidation desulfurization of fuel. The proper sizes (window size and pore size) of UIO-66-NH 2 can effective sealing PW 4 as monomolecular active component and prevent PW 4 leaching during the reaction process. At the same time, the introduction of GO can improve the electron transfer of the catalyst. Characterization tests showed that the active component PW 4 was successfully encapsulated with a loading amount of 0.19 mmol/g. The desulfurization results indicated that the PW 4 @UIO-66-NH 2 /GO has excellent catalytic activity, which can remove 99.9% sulfides in model fuel, and the activity did not decrease obviously after repeated use for ten times. The good activity and reusability of PW 4 @UIO-66-NH 2 /GO attributes to the introduction of GO and UIO-66-NH 2 . In addition, based on GC-MS and EPR results, a possible mechanism of desulfurization reaction was proposed.

The extensive application of Mg alloys is restricted by their poor corrosion, wear resistances and long-term service performance. Although the low-cost epoxy (EP) coating has excellent corrosion resistance , many pores and cracks are easily formed during the curing process, leading to the deterioration of barrier capacity. This study reports an epoxy-based nanocomposite coating, fabricated through the hybridization of γ-(2, 3-epoxypropoxy) propytrimethoxy silane modified silica nanoparticles and graphene oxide (mSiO 2 /GO). The insulating SiO 2 particles can isolate the direct contact between Mg alloy substrate and GO sheets, avoiding the formation of micro-cells and preventing the galvanic corrosion . The SiO 2 /GO in EP coating with “crack pinning and bridge” structure has reduced porosity and enhanced consistency, which effectively prevents crack propagation and electrolyte penetration. The corrosion rate of SiO 2 /GO/EP coating is 374 and 10 times lower than that of pure EP coating and individual GO/EP coating, respectively. The wear rate of GO/EP and SiO 2 /GO/EP coating specimens is 81.2 % and 70.4 % less than that of the pure EP coating, which is related to the favorable lubricating performance and high hardness of GO nanosheets . The results show that the embedding of well-distributed mSiO 2 -GO hybrids can remarkably improve the barrier effect and anti-corrosion of EP coating.
