One-pot synthesis of TEA functionalized and NiSe embedded rGO nanocomposites for supercapacitor application.

NiSe and NG-NiSe (triethanolamine functionalized and NiSe embedded rGO), as electrode materials for supercapacitor application, were prepared by a hydrothermal technique. XRD confirmed the formation of pure NiSe and NG-NiSe nanocomposites, which showed a hexagonal crystalline structure of NiSe. The structural morphology and particle size of NiSe and NG-NiSe were measured using FESEM and HRTEM analysis, respectively. The oxidation states and elemental compositions of NG-NiSe were investigated by XPS. The electrochemical behaviours of the materials were studied using CV, GCD, and EIS spectra. NG-NiSe showed higher capacitance performance compared to pure NiSe, due to the synergetic effects on the rGO/TEA/NiSe nanocomposite during one-pot synthesis. The energy density and power density of a N-rGO//NG-NiSe asymmetric cell were 28.25 W h kg-1 and 700 W kg-1, respectively.

Synergistic impacts of composite formation and doping techniques to boost the photocatalytic aptitude of the BiFeO3 nanostructure

Reduced graphene oxide (rGO)-based rare-earth-doped metal oxide nanocomposites have shown exceptional photocatalytic efficiency for water splitting and remediation. In this study, we used a simple wet chemical technique to create gadolinium (Gd) doped bismuth ferrite (BiFeO 3 ) nanoparticles, which we then grafted onto an rGO using an ultrasonication strategy to create the nanocomposite (Gd-doped BiFeO 3 /rGO). The photocatalytic properties of the Gd-doped BiFeO 3 /rGO composite as produced were studied and compared to those of pure BiFeO 3 and Gd-doped BiFeO 3 . The photocatalytic capabilities of the three synthesized materials were tested by determining their effectiveness in removing methylene blue dye (MBD) from an aqueous solution at the expanse of solar irradiation. The Gd-doped BiFeO 3 /rGO showed notable photocatalytic efficiency compared to bare BiFeO 3 and Gd-doped BiFeO 3 samples. Specifically, the Gd-doped BiFeO 3 /rGO photocatalyst removed 87% MB dye (rate constant ∼ 0.016 min −1 ) after solar irradiation for 120 min, whereas the pure BiFeO 3 and Gd-doped BiFeO 3 samples degraded only 55% (rate constant ∼ 0.003 min −1 ) and 66% (rate constant ∼ 0.008 min −1 ) MB, respectively under the same conditions. The rGO based nanocomposite demonstrated excellent transient photocurrent response, which was 11-fold and 2.98-fold larger than pristine BiFeO 3 and Gd-doped BiFeO 3 , respectively. The increased photocatalytic activity of rGO-based photocatalysts may be attributed to the synergistic impact of Gd doping and rGO nanosheets inclusion, which results in a redshift in light absorption. Employed strategies suppressed electron-hole re-combination and charge-transfer resistance but boosted the electronic conductivity (due to the existence of conjugated -electrons) and diffusive properties (due to nanoarchitecture). Such an effective Gd-doped BiFeO 3 /rGO nanocomposite may give rise to novel pathways for achieving visible light response photocatalysts.

Reduced graphene oxide modified melamine sponges filling with paraffin for efficient solar-thermal conversion and heat management

A novel type of reduced graphene oxide (rGO) modified melamine sponges (rGS) filling with paraffin (rGS-pf) is developed for efficient solar-thermal conversion and heat management. The microstructures, filling and holding capacity of paraffin in porous rGS, solar-thermal energy conversion and energy harvesting efficiency of the prepared rGS-pf have been investigated systematically. The content of rGO nanosheets coated on the skeletons of rGS-pf is only 0.11%, while the loading content of paraffin in the rGS-pf is as high as 97.53%. Based on the solar-thermal conversion property of rGO nanosheets in the rGS-pf and the heat storage ability of paraffin in the rGS-pf, the proposed rGS-pf provides excellent performance for heat management. The efficiency of solar-thermal conversion could reach up to 92.5%. The thermo-regulation provided by the proposed rGS-pf is real-time, repeatable and long-term stable. The results in this study provide valuable guidance for developing functional materials for efficient solar-thermal conversion and heat management.

RGO functionalized (Ni,Fe)-OH for an efficient trifunctional catalyst in low-cost hydrogen generation via urea decomposition as a proxy anodic reaction.

Green hydrogen derived from the water-electrolysis route is emerging as a game changer for achieving global carbon neutrality. Economically producing hydrogen through water electrolysis, however, requires the development of low-cost and highly efficient electrocatalysts via scalable synthetic strategies. Herein, this work reports a simple and scalable immersion synthetic strategy to deposit reduced graphene oxide (rGO) nanosheets integrated with Ni-Fe-based hydroxide nanocatalysts on nickel foam (NF) at room temperature. As a result of synergetic interactions among the hydroxides, rGO and NF, enhanced catalytic sites with improved charge transport between the electrode and electrolyte were perceived, resulting in significantly enhanced oxygen evolution reaction (OER) activity with low overpotentials of 270 and 320 mV at 100 and 500 mA cm-2, respectively, in a 1.0 M KOH aqueous electrolyte. This performance is superior to those of the hydroxide-based electrode without incorporating rGO and the IrO2-benchmark electrode. Furthermore, when the conventional OER is substituted with urea decomposition (UOR) as a proxy anodic reaction, the electrolyzer achieves 100 and 500 mA cm-2 at a lower potential by 150 and 120 mV, respectively than the OER counterpart without influencing the hydrogen evolution reaction (HER) activity at the cathode. Notably, the rGO-incorporated electrode delivers a spectacularly high UOR current density of 1600 mA cm-2 at 1.53 V vs. RHE, indicating the decomposition of urea at an outstandingly high rate.

Construction of a sensitive electrochemical sensor based on hybrid 1 T/2H MoS2 nanoflowers anchoring on rGO nanosheets for the voltammetric determination of acetaminophen

In this work, an ultrasensitive electrochemical sensor towards quantitative detection of acetaminophen (AP) based on hybrid of metallic 1 T and semiconductive 2H phase molybdenum disulfide (1 T/2H MoS2) anchored on rGO sensing platform was constructed. The XRD, FESEM, FETEM and XPS analysis indicates that nanoflowers 1 T/2H MoS2 with walnut-like fold structure were in-situ loaded onto the surface of rGO nanosheets by the hydrothermal approach. The formation of stabilized 1 T MoS2 is associated with the influence of GO. The electrochemical tests of CV, EIS and DPV show that the hybrid composite MoS2/rGO remarkably promoted the detecting performance owing to the increased conductivity of 1 T MoS2 that can facilitate charge transfer kinetics, the great active sites on both basal and edge of planes of 1 T/2H MoS2 and the synergic effect of 1 T/2H MoS2 and rGO. After the test condition optimization, MoS2/rGO/GCE sensor has great electrocatalytic activity towards AP with wide linear range of 0.005–300 μM and low limit of detection of 1.7 nM (S/N = 3). Furthermore, the sensor shows excellent stability, repeatability, reproducibility and anti-interference performance. All results proved that the GO-assisted hydrothermal prepared hybrid 1 T/2H MoS2/rGO is promising material for electrochemical analysis.

Polyaniline intercalated MoS2 nanosheet array aligned on reduced oxide graphene as high performance anode for lithium-ion batteries

To improve the electronic and ionic transfer in MoS2, we develop hierarchical structure of MoS2/polyaniline/reduced graphene oxide (denoted as MoS2/PANI/rGO), in which PANI intercalated MoS2 nanosheets are vertically grown on rGO nanosheets. PANI together with rGO builds 3D conductive networks, facilitating electronic transfer both in and vertical to the layers of MoS2. Moreover, MoS2 nanosheets exhibit expanded interlayers owing to the intercalation of PANI, which is beneficial for the kinetics of Li+ storage/release. As anode for lithium-ion batteries, MoS2/PANI/rGO exhibits superior long-term cyclic performance with a reversible capacity of 1035.1 mA h g−1 at 2 A g−1 after 550 cycles. It presents excellent rate performance of 676.9 mA h g−1 even at 10 A g−1. The MoS2/PANI/rGO composite could be a promising anode material for high performance lithium-ion batteries.

Emerging Stacked Photocatalyst Design Enables Spatially Separated Ni(OH)2 Redox Cocatalysts for Overall CO2 Reduction and H2 O Oxidation.

Construction of photocatalytic systems with spatially separated dual cocatalysts is considered as a promising route to modulate charge separation/transfer, promote surface redox reactivities, and prevent unwanted reverse reactions. However, past efforts on the loading of spatially separated double-cocatalysts are limited to hollow structured semiconductors with inner/outer surface and monocrystalline semiconductors with different exposed facets. To overcome this limitation, herein, enabled by a unique stacked photocatalyst design, a facile and versatile strategy for spatial separation of redox cocatalysts on various semiconductors without structural and morphological restriction is demonstrated. The smart design begins with the deposition of light-harvesting semiconductors on reduced graphene oxide (rGO) nanosheets, followed with the coverage of Ni(OH)2 outer layer. The ternary photocatalysts exhibit superior activities and stabilities of H2 O oxidation and selective CO2 -to-CO reduction, remarkably surpassing other counterparts. The origin of the enhanced performance is attributed to the synergistic interplay of rGO@Ni(OH)2 reduction cocatalysts surrounding the semiconductors and Ni(OH)2 oxidation cocatalysts directly supported by the semiconductors, which mitigates the charge recombination, supplies highly active and selective sites for overall reactions, and preserves the semiconductors from photocorrosion. This work presents a new approach to regulating the position of dual cocatalysts and ameliorating the net efficiency of photoredox catalysis.

Design of hierarchical and mesoporous FeF3/rGO hybrids as cathodes for superior lithium-ion batteries

Iron fluoride (FeF3) is considered as a promising cathode material for Li-ion batteries (LIBs) due to its high theoretical capacity (712 mAh/g) with a 3e− transfer. Herein, we have designed a strategy of hierarchical and mesoporous FeF3/rGO hybrids for LIBs, where the hollow FeF3 nanospheres are the main contributor to the specific capacity and the 2D rGO nanosheets are the matrix elevating the electronic conductivity and buffering the volume expansion. The unique FeF3/rGO hybrid can be rationally synthesized by a non-aqueous in-situ precipitation method, offering the merits of large specific surface area with rich active sites, fast transport channels for lithium ions, effective alleviation of volume expansion during cycles, and accelerating the electrochemical reaction kinetics. The FeF3/rGO hybrid electrode possesses a high initial discharge capacity of 553.9 mAh/g at a rate of 0.5 C with 378 mAh/g after 100 cycles, acceptable rate capability with 168 mAh/g at 2 C, and feasible high-temperature operation (320 mAh/g at 70 °C). The superior electrochemical behaviors presented here demonstrates that the FeF3/rGO hybrid is a potential electrode for LIBs, which may open up a new vision to design high-efficiency energy-storage devices such as LIBs based on transition metal fluorides.

3D network-like rGO-MoSe2 modified g-C3N4 nanosheets with Z-scheme heterojunction: Morphology control, heterojunction construct, and boosted photocatalytic performances

The transition-metal dichalcogenides (TMDs) is a promising photocatalyst for degrading contaminant, while limited active sites and poor carrier mobility are the primary challenges for improving photocatalytic degrading efficiencies in both bare TMDs and TMDs-based photocatalysts. A rGO-MoSe2 composite with 3D network hierarchical structure was fabricated by the GO-assisted solvothermal method. And then rGO-MoSe2/g-C3N4 3D/2D hierarchical structures were constructed by combining rGO-MoSe2 with g-C3N4 nanosheets. The optimal rGO-MoSe2/g-C3N4 composite exhibited the highest photocatalytic degrading rate of 97.4% towards RhB under simulated solar light, and its pseudo-first-order apparent rate constant (k) was 0.0715 min−1, being 5.9 and 12.5-folds higher than that of MoSe2/g-C3N4 (0.0121 min−1) and bare g-C3N4 (0.00573 min−1), respectively. The 3D/2D hierarchical structure endow rGO-MoSe2/g-C3N4 composite with the improved light-harvesting and abundant active sites, supported by the DRS and BET analyses. And rGO nanosheets could act as efficient transfer and separation channels for electron-hole pairs between MoSe2 and g-C3N4, confirmed through the photocurrent response and EIS tests. According to the results of DRS spectra and Mott-Schottky plots, the spatial behavior of photo-induced carriers at interface of rGO-MoSe2/g-C3N4 would comply to a Z-scheme transfer pathway under the synergy effects of the internal electric field and band bending.

Plate-barrier architecture of rGO-TiO2 derived from MXene for constructing well-aligned polymer nanocomposites with excellent dielectric performance

Dielectric polymers are playing increasingly important roles in advanced electronics and electric power systems, because of their high dielectric strength, stability, and lightweight. However, the relatively low intrinsic dielectric constant of dielectric polymers hinders their further applications. Herein, dielectric polymer composites were fabricated by blending with plate-barrier architecture fillers, which are comprised of reduced graphene oxide (rGO) and intercalated titanium dioxide (TiO2) cubes. TiO2 cubes are homogeneously and controllably integrated onto rGO nanosheets utilizing 2D transition metal carbides (MXene) by means of shape match. TiO2 cubes could serve as joints to anchor rGO nanosheets for more effective polarization, and as barriers to impede the conductive contact of rGO nanosheets. In the nanocomposites, rGO nanosheets possess high alignment and overlap area resorting to the anchoring effect of TiO2, which increases the micro-capacitors in series that greatly enhance the dielectric constant. Therefore, it is investigated that the nanocomposites exhibit a high dielectric constant (211) and ultralow dielectric loss (0.104). Moreover, the enhancement mechanism of the micro-capacitors was also revealed by the finite element simulation. This contribution provides a novel strategy to fabricate well-aligned nanocomposites that are promising in electronics flexible materials.

Pervaporation Membranes for Seawater Desalination Based on Geo-rGO-TiO2 Nanocomposites. Part 1: Microstructure Properties.

This is the first of two papers about the synthesis and microstructure properties of the Geo–rGO–TiO2 ternary nanocomposite, which was designed to suit the criteria of a pervaporation membrane for seawater desalination. The performance and capability of Geo–rGO–TiO2 as a seawater desalination pervaporation membrane are described in the second paper. A geopolymer made from alkali-activated metakaolin was utilized as a binder for the rGO-TiO2 nanocomposite. A modified Hummer’s method was used to synthesize graphene oxide (GO), and a hydrothermal procedure on GO produced reduced graphene oxide (rGO). The adopted approach yielded high-quality GO and rGO, based on Raman spectra results. The nanolayered structure of GO and rGO is revealed by Transmission Electron Microscopy (TEM) images. The Geo–rGO–TiO2 ternary nanocomposite was created by dispersing rGO nanosheets and TiO2 nanoparticles into geopolymer paste and stirring it for several minutes. The mixture was then cured in a sealed mold at 70 °C for one hour. After being demolded, the materials were kept for 28 days before being characterized. Fourier Transform Infrared (FTIR) and X-ray Diffraction (XRD) measurements revealed that the geopolymer matrix efficiently bonded the rGO and TiO2, creating nanocomposites. Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS) was used to examine the morphology of the outer layer and cross-sections of nanocomposites, and the results displayed that rGO were stacked on the surface as well as in the bulk of the geopolymer and will potentially function as nanochannels with a width of around 0.36 nm, while TiO2 NPs covered the majority of the geopolymer matrix, assisting in anti-biofouling of the membranes. The pores structure of the Geo–rGO–TiO2 were classified as micro–meso pores using the Brunauer–Emmet–Teller (BET) method, indicating that they are appropriate for use as pervaporation membranes. The mechanical strength of the membranes was found to be adequate to withstand high water pressure during the pervaporation process. The addition of rGO and TiO2 NPs was found to improve the hyropobicity of the Geo–rGO–TiO2 nanocomposite, preventing excessive seawater penetration into the membrane during the pervaporation process. The results of this study elucidate that the Geo–rGO–TiO2 nanocomposite has a lot of potential for application as a pervaporation membrane for seawater desalination because all of the initial components are widely available and inexpensive.

Lemon Juice Assisted Green Synthesis of Reduced Graphene Oxide and Its Application for Adsorption of Methylene Blue

Sustainable synthesis of reduced graphene oxide (rGO) is of crucial significance within the development of carbon nanomaterials. In this study, a green and eco-friendly strategy for the synthesis of rGO using lemon juice as the reducing agent for graphene oxide (GO) without using toxic and harmful chemicals was demonstrated. The reduction with lemon juice effectively eliminated the oxygen-containing functionalities of GO and regenerated the conjugated systems as confirmed by the UV-vis and FTIR spectroscopic and X-ray diffraction analyses. Microscopic evaluation showed the successful manufacturing of exfoliated and separated few layers of nano-sheets of rGO. The application of the resultant rGO as an adsorbent for organic pollutants was investigated using methylene blue (MB) as a model. The adsorption kinetics of MB on rGO is best matched with the pseudo-second-ordered kinetic model and the Langmuir model with a high adsorption capacity of 132.2 mg/g. The rGO exhibited good reusability with a removal efficiency of 80.4% in the fourth cycle. This green method provides a new prospect for the large-scale production of rGO in a cost-effective and safe manner.

Systematic investigating on the broadband solar absorption and photo-thermal conversion performance of TiN@rGO plasmonic nanofluids

Strong solar capture and high heat transfer are extremely vital for designing solar-to-heat absorber to improve photo-thermal conversion efficiency in direct absorption solar collectors (DASCs). In this paper, the plasmonic nanofluids containing reduced graphene oxides (rGO) decorated with titanium nitride (TiN) nanoparticles were prepared. Their superior solar-thermal conversion efficiency and heat transfer property was based on the synergy between the Localized Surface Plasmon Resonances (LSPR) effect of TiN and the high thermal conductivity of rGO. The optical properties of plasmonic nanofluids were investigated with the concentration and penetration depth, which indicated that the existence of TiN on graphene could improve the light-capture ability. The results indicated that the TiN@rGO plasmonic nanofluids could be used for DASCs applications, even under the low mass concentrations. Specifically, the maximum photo-thermal conversion efficiency of the plasmonic nanofluids was 66.74% at 40 ppm concentration, which was about 23% higher than that of pure water. And, the experimental results show that the photothermal conversion efficiency will be reduced if the nanofluid concentration is higher than the optimal concentration. This work exhibited the potential application of plasmonic-graphene nanofluids in DASCs. • Hybrid nanofluids containing TiN nanoparticle and rGO nanosheets were prepared. • The photo-thermal potency promoted by the synergistic effects between rGO and TiN nanoparticles. • The plasmonic nanofluid could realize both broad spectrum absorption and high thermal conductivity. • A collector solar-to-heat efficiency of 66.74% is achievable for 40 ppm TiN@rGO nanofluid.

In situ redox reaction induced firmly anchoring of Na3V2(PO4)2F3 on reduced graphene oxide & carbon nanosheets as cathodes for high stable sodium-ion batteries

NASICON-type Na 3 V 2 (PO 4 ) 2 F 3 is considered as one of the most promising cathodes for sodium-ion batteries due to its high operating potential, fast ion transport and superior structural stability. However, its poor rate capability and insufficient cyclability hinder its future practical applications. Herein, a hybrid of Na 3 V 2 (PO 4 ) 2 F 3 nanoparticles firmly anchoring on reduced graphene oxide & carbon (rGO&C) nanosheets is synthesized through an in situ redox reaction. The ethylenediamine and oxalic acid not only could induce the nucleation of Na 3 V 2 (PO 4 ) 2 F 3 along the surface of rGO, but also act as carbon sources of amorphous carbon, serving as binders to firmly and densely couple Na 3 V 2 (PO 4 ) 2 F 3 with the three-dimensional continuous conductive network constructed by rGO nanosheets. The composite displays excellent rate capability and remarkable cycling stability (capacity retention of 81.9% for 1000 cycles at 30 C), due to the 2D rGO&C nanosheets and anchored ultrafine Na 3 V 2 (PO 4 ) 2 F 3 nanoparticles shorten diffusion length of the ions and electrons, the firm connectivity between Na 3 V 2 (PO 4 ) 2 F 3 and rGO&C nanosheets enables high structure stability to relieve the stress and strain generated during the cycling. The strategy can be extended to prepare other NASICON vanadium phosphates cathodes materials for advanced batteries. • Na 3 V 2 (PO 4 ) 2 F 3 nanoparticles firmly anchoring on rGO&C nanosheets. • Ethylenediamine and oxalic acid induce the nucleation of Na 3 V 2 (PO 4 ) 2 F 3 on rGO. • The hybrid exhibits excellent rate capability and remarkable cycling stability.

Facile solid−phase synthesis of layered NiS/rGO nanocomposite for high−performance hybrid supercapacitor

Generally, transition metal sulfides and their composites are prepared by tedious and uneconomical liquid−phase synthesis methods. In this work, we developed a facile solid−phase synthesis route for preparing NiS/rGO nanocomposite by thermal treating a ternary solid mixture of nickel formate, elemental sulfur and GO in an autoclave under ambient atmosphere. The prepared nanocomposite exhibits a loose layered structure, spherical or ellipsoidal NiS nanoparticles with a size of 20–100 nm disperse on the well−separated rGO nanosheets. Due to the unique layered structure, the obtained NiS/rGO nanocomposite exhibits an ultrahigh specific capacity of 299.7 mAh g−1 (2157.8 F g−1) at a current density of 2 A g−1 and good rate capacity (161.2 mAh g−1 at 15 A g−1). The hybrid supercapacitor device based on the layered NiS/rGO nanocomposite and an interconnected hierarchical porous carbon delivers a high specific energy of 56.1 Wh kg−1 at a specific power of 880 W kg−1 while exhibits a high capacity retention of 92.4% after 30,000 charge/discharge cycles, demonstrating the promising potential of the developed solid−phase synthesis route for the preparation of NiS/rGO nanocomposites using for high−performance hybrid supercapacitor.

Synthesis of CuO/rGO nanocomposites for carcinogenic Congo red photodegradation

Removal of carcinogenic Congo red from polluted water is challenging because of its chemical stability and inertness. Here, CuO microsphere assembled rGO nanosheets were successfully fabricated by a simple hydrothermal method for photocatalytic degradation of Congo red. The morphology and microstructure of the CuO/rGO nanocomposites were studied by scanning electron microscopy and X-ray diffraction. The results showed that the produced CuO has a spherical flower like structure that crystallised in the monoclinic crystal phase with a diameter of about 5 μm, combined with thin rGO nanoplates. Fourier transform infrared spectroscopy and Raman spectroscopy confirmed the existence of chemical bonds and vibrational modes of both CuO and rGO. The effect of H2O2 content on the photocatalytic characteristics of as-prepared samples was investigated. The results showed that H2O2 played a key factor in the photocatalytic efficiency. The content of 1 ml H2O2 (30%) exhibited the highest photocatalytic efficiency toward Congo red dye degradation in CuO/rGO (50 mg) under UV light radiation, where it completely removed over 95% Congo red in 100 ml of solution (20 mg L−1) after 120 min of illumination.

Catalyst-free nitro-coupling synthesis of azo-linked conjugated microporous polymers with superior aqueous energy storage capability

Developing methods to construct conjugated microporous polymers (CMPs) with desirable structures is a crucial undertaking. However, obtaining azo-CMPs with extended azaacene cores is immensely challenging. Herein, we disclose the facile synthesis of diquinoxalino[2,3-a:2′,3′-c]-phenazine-core CMP (3Qn-CMP; core diameter, ∼1.6 nm) via the one-step hydrothermal homocoupling of nitro monomers in a mixture solution of N,N-dimethylformamide (or N,N-dimethylacetamide) and water (1:3, v/v). A 3Qn-CMP/rGO hybrid is readily prepared from CMP spheres (diameter, 0.5–1.5 µm) anchored on reduced graphene oxide (rGO) nanosheets (∼3 layers) by synergizing the one-pot synthesis of (rGO) for intercalation and self-assembly. The highly porous hybrid features dual redox active sites with azo and imine linkages and efficient charge conduction. 3Qn-CMP and 3Qn-CMP/rGO exhibit outstanding energy storage capacity, current density tolerance (1–50 A g−1), and long-term cycling stability in aqueous acidic electrolytes. 3Qn-CMP and 3Qn-CMP/rGO also produce high specific capacitances of 615.4 and 847.8 F g−1, respectively, at 1 A g−1. Approximately 99.1% of this capacitance can be retained over 50,000 continuous charge/discharge cycles at 50 A g−1. To the best of our knowledge, our hybrid outperforms most organic molecules or CMP-/rGO-based composites reported in the literature in terms of capacitance and cycling durability. This work provides a general strategy to access a new library of CMPs and hybrids with multilevel elaborate architectures tailored for target applications, such as electrochemical energy storage and catalysis.
