A new rare earth borate photocatalytic material ErBO 3 has been successfully prepared by hydrothermal method. Due to the particularities of f – f electron transition of Er 3+ ion, ErBO 3 becomes a visible light responsive photocatalytic material. ErBO 3 exhibits certain photodegradation ability to RhB molecules. Then, a series of GO@ErBO 3 composites were prepared by using GO as a co-catalyst. The properties of samples were characterized using XRD, FE-SEM, XPS, FT-IR, Raman, and BET methods. Through detection analysis, it was found that the combination of GO could improve the visible light absorption performance, the specific surface area and the photogenerated carrier separation efficiency of ErBO 3 material, and then the visible light responsive photocatalytic material 0.5 wt%GO@ErBO 3 with excellent performance was obtained. The prepared composite exhibited high degradation performance towards pollutants which affirmed potential the applicability of the proposed degradation system for degrading real industrial effluents.

The adsorption processes of methylene blue from aqueous solution on Fe3O4/HKUST-1 and Fe3O4/HKUST-1/GO composites were compared. The addition of GO has greatly decreased the surface area and pore volume, led to smaller pore size, and enhanced the adsorption capacity of Fe3O4/HKUST-1/GO. The different interesting phenomena and the effect of GO were analyzed. The high adsorption capacity, excellent reusability and stability make Fe3O4/HKUST-1/GO attractive for the removal of MB from aqueous solution.

Magnetic nanoparticle-coated graphene oxide (GO) can be oriented in polymers under magnetic field due to the anisotropy of GO and excellent magnetism of magnetic nanoparticles. In this study, ferroferric oxide nanoparticles coated GO (Fe 3 O 4 -GO) was synthesized successfully using oxidation-coprecipitation method. The synthesized Fe 3 O 4 -GO was then added to epoxy and oriented by applying magnetic field using (1) the electromagnetic coil and (2) permanent magnets to toughen the epoxy matrix. Non-isothermal differential scanning calorimetry (DSC) tests were performed to determine the curing process of Fe 3 O 4 -GO/E-51/3a-methyl-5,6-dihydro-4 H -isobenzofuran-1,3-dione (MeTHPA)/2,4,6 Tris(dimethyl aminomethyl)phenol (DMP-30) system (Fe 3 O 4 -GO/E-51/MeTHPA/DMP-30). Transmission electron microscope images show that Fe 3 O 4 nanoparticles were coated on the GO surface homogenously and Fe 3 O 4 -GO were highly oriented in E-51/MeTHPA/DMP-30 epoxy system under different magnetic field conditions. The maximum impact strength of Fe 3 O 4 -GO/E-51/MeTHPA/DMP-30 composite was observed at 0.2 wt% Fe 3 O 4 -GO loading, with values of 28.64 and 30.54 kJ/m 2 in case of the magnetic field applied through permanent magnets and electromagnetic coil respectively, which is an increase by 39.6 and 48.8% respectively when compared with the pure E-51/MeTHPA/DMP-30 system (20.52 kJ/m 2 ). In addition, at 0.4 wt% Fe 3 O 4 -GO loading and application of magnetic field through electromagnetic coil, the maximum increase in flexural modulus was observed, which was increased by 41.8% and 17.23% compared with the pure epoxy system and the one without application of magnetic field at same Fe 3 O 4 -GO loading respectively. The fracture morphologies from the scanning electron microscope also indicated that the oriented Fe 3 O 4 -GO under magnetic field improved the toughness of the E-51/MeTHPA/DMP-30 resin system.

Low surface free energy coating can effectively suppress the initial adhesion of fouling organism. However, continuous attack of corrosive medium will inevitably weaken the coating barrier effect. Herein, a novel self-healing coating based on fluorine‑silicon copolymer (FSiAC) and 0.1 wt% graphene oxide (GO) was prepared by free radical copolymerization . The formed GO/FSiAC coating with the surface free energy of 22.6 mJ/m 2 effectively suppressed the adhesion of chlorella, and the inhibition rate was 97%. EIS results showed that the impedance of GO/FSiAC coating increased and the coating porosity decreased with immersion time, indicating that the coating had self-healing property. DSC and FTIR measurements revealed that during the immersion process, the coating cross-linking degree increased due to the formation of net-like Si-O-Si structure. The barrier performance of GO and the self-healing capacity contributed to the superior corrosion resistance of the coating. The outstanding antifouling property is dependent on the low surface free energy of the coating and the antibacterial effect of GO. Novel GO/FSiAC coating with excellent antifouling and good self-healing anticorrosion performance has a potential application in marine engineering fields.

Removal of 1,3-butadiene from cigarette smoke plays an important role in human health and environmental protection. Herein, a series of UiO-66 X% containing different ratios of the -NH2group was synthesized via the solvothermal method by using terephthalic acid (H2BDC) and 2-aminoterephthalic acid (NH2-BDC) as ligands. Using GO as support, a series of UiO-66-NH2/GO Y% were prepared by controlling the ratio of UiO-66-NH2and GO. The effects of -NH2and GO contents on the structure and composition of MOFs were investigated. Finally, the different -NH2contents of UiO-66 X% and the different GO contents of UiO-66-NH2/GO Y% were applied in 1,3-butadiene removal from cigarette smoke. The results showed that UiO-66 X% with the higher contents of -NH2showed a higher rate of 1,3-butadiene removal, and UiO-66-NH2/GO Y% with the GO contents of 5% showed the highest removal rate of about 33.85%, which was 25.54% higher than that of activated carbon. In addition, the saturation capacity of the adsorbent materials for 1,3-butadiene was as high as 210.01–239.54 mg/g, showing great potential in reducing harmful components in cigarette smoke and environmental protection.Keywords:UiO-66;UiO-66-NH2/GO;1,3-butadiene removal;cigarette smoke

UiO-66-NH 2 @GO nanoparticles were synthesized by growing UiO-66-NH 2 on graphene oxide (GO) nanosheets. The obtained nanoparticles were incorporated in polyimide (PI) matrix to improve the CO 2 separation performance. The crystalline structure, interaction between UiO-66-NH 2 and GO and the dispersion of UiO-66-NH 2 @GO were characterized by various techniques. Owning to the interaction between UiO-66-NH 2 and GO, UiO-66-NH 2 nanocrystals were well-anchored on GO sheets and the size was tailored. Also, it can be found that the high-aspect GO nanosheets in polymer matrix improved the dispersion of UiO-66-NH 2 nanoparticles. The high porosity of UiO-66-NH 2 @GO and inherent adsorption property to CO 2 significantly enhanced the gas separation performance of composite membranes compared to pristine PI membrane. The developed UN@GO-PI mixed matrix membrane with 5 wt% of UiO-66-NH 2 @GO loading showed excellent and stable CO 2 /N 2 separation performance with the CO 2 permeability of 7.28 Barrer and the CO 2 /N 2 selectivity of 52.

Employing nanofluid flooding as an advanced enhanced oil recovery (EOR) technique has emerged as a groundbreaking approach for the extraction of residual hydrocarbons from increasingly depleted reservoirs. The innovative utilization of nanocomposites, specifically Janus SiO2 (JS) particles amalgamated with graphene oxide (GO), constitutes the focus of this research. We elucidate how this novel JS@GO nanocomposite enhances oil displacement through its exemplary interfacial activity, substantiated by various empirical evaluations such as contact angle and interfacial tension tests. Moreover, core flooding experiments corroborate the nanocomposite’s superior efficiency in augmenting oil recovery vis-a-vis traditional methodologies, which was due to the improvement of both emulsifying ability and amphiphilicity. The results of this research underscore the considerable promise the JS@GO nanofluid holds for future EOR applications, providing a compelling alternative for revitalizing oil production from heretofore unyielding reservoirs.

Magnetic core–shell spheres Fe 3 O 4 @MOFs and Fe 3 O 4 @MOFs/GO were prepared using layer by layer assembly method. Fe 3 O 4 @MOFs and Fe 3 O 4 @MOFs/GO were characterized by XRD , FTIR, SEM, TEM and VSM. The results showed that both magnetic spheres were with core–shell structure. The method was proved to be valuable for producing core–shell structure with porous nanocomposite materials as shell. Methylene blue was selected as drug model to study the drug loading of the synthesized spheres. It was found that the addition of graphene oxide (GO) enhanced the drug loading amount of magnetic sphere.

ZIF-8@GO-X (X = 0, 2.48%, 4.07%, 7.83%, and 20.03%) composites were prepared using GO and ZIF-8. The composites were used to absorb Cu(Ⅱ) from aqueous solutions. With increasing GO content, the adsorption of the ZIF-8@GO-X composites first increased and then decreased. The Cu(Ⅱ) adsorption of ZIF-8@GO-7.83% reaches a maximum among ZIF-8@GO-X composites (X = 0, 2.48%, 4.07%, 7.83%, and 20.03%). The adsorption kinetics , adsorption isotherm , adsorption thermodynamics, and adsorption mechanism of Cu (II) by ZIF-8@GO-7.83% were studied in this paper. The results showed that the adsorption reached equilibrium at 120 min, and ZIF-8@GO-7.83% approached equilibrium relatively quickly. When the temperature was 45 °C and the Cu(Ⅱ) concentration was 40 mg/L, the maximum adsorption capacity of ZIF-8@GO-7.83% for Cu(Ⅱ) reached 482.29 mg/g. The equilibrium data and kinetics were well described by Langmuir and pseudo-first-order models, respectively. Final experiments with real factory wastewater (initial Cu(Ⅱ) concentration of 670 mg/L) revealed that 0.37 g/L ZIF-8@GO-7.83% can efficiently reduce the Cu(Ⅱ) concentration to below 2 mg/L.

A novel AgBr and GO co-decorated g-C 3 N 4 /Ag 2 WO 4 (g-C 3 N 4 /Ag 2 WO 4 /AgBr/GO) composite was successfully fabricated by hexadecyl trimethyl ammonium bromide (CTAB)-assisted co-deposition of AgBr and GO onto g-C 3 N 4 /Ag 2 WO 4 composite. The as-prepared composites were characterized by XRD, SEM, TEM, FT-IR, BET, XPS, UV–vis diffuse reflectance spectra (DRS), photoluminescence spectra (PL), and electrochemistry impedance spectroscopy (EIS). The photocatalytic efficiency for tetracycline (TC) degradation over the as-prepared g-C 3 N 4 /Ag 2 WO 4 /AgBr/GO composite is 91.64% within 100 min simulated sunlight irradiation, which is nearly 2.59 and 5.25-folds greater than those of the g-C 3 N 4 /Ag 2 WO 4 and g-C 3 N 4 samples. The enhancement of photocatalytic performance is mainly ascribed to the introduction of AgBr and GO, which serve as photosensitizer and electron acceptor, respectively, confirmed by the results of DRS, PL, and EIS. The active species trapping experiments confirmed that O 2 − and h + are the dominant reactive species responsible for TC degradation. Furthermore, a reasonable n-n heterojunction-based photocatalytic mechanism for the g-C 3 N 4 /Ag 2 WO 4 /AgBr/GO composite was proposed.

The intentional discharge of polycyclic aromatic hydrocarbons (PAHs) into the aquatic system from different industrial units has posed a serious threat to human health. To address the concerns associated with PAHs misuse, an efficient approach for developing affordable photocatalyst materials for PAHs degradation is much needed. In this study, we have explored co-precipitation and hydrothermal methods to synthesize Fe 3 O 4 /GO/g-C 3 N 4 ternary composites and utilized them as photocatalyst materials for the degradation of naphthalene. Fe 3 O 4 /GO/g-C 3 N 4 nanocomposite demonstrated superior degradation performance, with 87.56% naphthalene degradation achieved in 140 min under visible light irradiation, far outperforming Fe 3 O 4 /GO (77.42%) and Fe 3 O 4 (69.42%). The enhanced degradation of naphthalene by the Fe 3 O 4 /GO/g-C 3 N 4 composite was credited to the effective charge carrier separation and increased visible-light absorption induced by GO and g-C 3 N 4 . The impact of operating parameters on the catalytic efficiency of the Fe 3 O 4 /GO/g-C 3 N 4 catalyst was also examined. The findings of this study revealed that lower naphthalene concentration (10 mg/L), higher catalyst dosage (40 mg), and moderate pH conditions (pH 5 to pH 9) were favorable for photocatalytic activity. The degradation of naphthalene followed pseudo-first-order kinetics with a rate constant value of 0.0137 min −1 . The generation of radicals ( • OH and O 2 •− ) liable for the degradation of naphthalene was corroborated through electron paramagnetic resonance analysis and quenching experiments. Furthermore, the Fe 3 O 4 /GO/g-C 3 N 4 photocatalyst exhibited promising reusability in five consecutive cyclic runs, validating its excellent stability.

The bio-based epoxy nanocomposite (GAER/DOPO-POSS) was prepared from gallic epoxy resin (GAER) and polyhedral oligomeric silsesquioxane (which containing 9,10-dihydrogen-9-oxo-10-phosphorus-phenanthrene-10-oxide groups, called DOPO-POSS). The polyhedral oligomeric silsesquioxane containing epoxy groups (E-POSS) was grafted onto aminated graphene oxide (E-GO), then the novel POSS-E-GO was obtained. The POSS-E-GO was used as modifier for GAER/DOPO-POSS nanocomposite. The influences of POSS-E-GO content on mechanical properties, dynamic mechanical properties and thermal stability of GAER/DOPO-POSS nanocomposites were determined. The experimental results show that POSS-E-GO can significantly improve the toughness of the GAER/DOPO-POSS nanocomposite. When 0.5wt% POSS-E-GO was added in GAER/DOPO-POSS nanocomposite, the impact strength of the nanocomposite was 4.74 kJ/m 2 higher than that in the absence of POSS-E-GO, meantime the initial thermal degradation temperature was 277 °C.
