Sunlight responsive superhydrophilic rGO-TiO2 nanocomposite coatings for photovoltaic applications

Transparent, superhydrophilic surfaces have a wide range of applications, especially for self-cleaning coatings in window panes and solar panels. Herein, reduced graphene oxide (rGO) decorated titanium dioxide (rGO-TiO2) nanocomposites (NCs) were synthesized by in-situ hydrothermal method. The X-ray diffraction and Raman spectroscopy confirmed the formation of anatase-brookite mixed phases TiO2 wherein rGO facilitates the anatase-brookite phase transformation. The NCs exhibit the transmittance of ∼79 % in the visible range and the lowest band gap of 3.03 eV. The wettability studies revealed that the films of rGO-TiO2 NCs became superhydrophilic (water contact angle <10°) upon 60 min sunlight exposure.

Hybrid TiO2–RGO nanocomposite as high specific capacitance electrode for supercapacitor

This study describes the fabrication of composite electrodes comprising TiO2 and reduced graphene oxide layers using a moderate-temperature hydrothermal method. The morphology, crystalline structure, chemical composition, and optical features of the prepared composites were analyzed by FE-SEM, x-ray diffraction, FTIR, and UV–visible spectroscopy. The cyclic voltammetry (CV) and Nyquist plots were used to assess the electrochemical and impedance responses of the composite electrodes, respectively. The analysis revealed that the incorporation of RGO reduced the TiO2 bandgap to 3.87 eV 3.02 eV and improved the specific capacitance, enhancing the TiO2-RGO electrode’s supercapacitive performance. CV studies highlight that the TiO2-RGO composite has a high specific capacitance of 152 F g−1 at a substantially faster scan rate of 25 mV s−1 in a 1.0 M-KOH dilute electrolyte. These findings confirmed the applicability of the fabricated electrodes as prospective supercapacitor electrodes.

Synergistically improved photovoltaic performances of dye-sensitized solar cells with metal-free organic cosensitizer and hybrid rGO-TiO2 photoanode

The photovoltaic performances of the dye-sensitized solar cells were considerably improved via comprising the device structure with the metal-free organic dye cosensitizer and the hybrid photoanode. The cosensitizer was composed of Eosin Y and Coumarin (EY-CM) dyes, and the hybrid photoanode was constructed with the reduced graphene oxide-anchored titanium dioxide (rGO-TiO2) nanocomposites. Due to the aggregation of highly conductive rGO with semiconductive TiO2, the nanocomposites exhibited the decreased interfacial resistance; hence, the electron transport could be improved in the solid-state medium of the photoanode. Meanwhile, the cosensitization of EY-CM dyes could give rise to the increased photon absorbance at the wide spectral range; and their energy level alignment with rGO-TiO2 could lead to the enhanced hopping conduction of the photo-generated electrons. Furthermore, the configuration of rGO-TiO2/EY-CM allowed us to increase the electron injection lifetime, which could reduce the photocarrier recombination at the photoanode/sensitizer interface. Owing to the synergetic effects from both the rGO-TiO2 hybrid photoanode and the EY-CM cosensitizer, the fabricated dye-sensitized solar cell eventually showed the increased power conversion efficiency up to ∼6.14% under 1-Sun illumination with 100 mW/cm2.

Pervaporation Membranes for Seawater Desalination Based on Geo-rGO-TiO2 Nanocomposites: Part 2-Membranes Performances.

This is part 2 of the research on pervaporation membranes for seawater desalination based on Geo-rGO-TiO2 nanocomposite. The quality of the Geo-rGO-TiO2 pervaporation membranes (PV), as well as the suitability of the built pervaporation system, is thoroughly discussed. The four membranes described in detail in the first article were tested for their capabilities using the parameters turbidity, salinity, total suspended solids (TSS), and electrical conductivity (EC). The membranes' flux permeate was measured as a function of temperature, and salt rejection was calculated using the electrical conductivity values of the feed and permeate. Fourier-transform infrared (FTIR) and X-ray diffraction (XRD) techniques were used to investigate changes in the chemical composition and internal structure of the membranes after use in pervaporation systems. The morphology of the membrane's surfaces was examined by means of scanning electron microscopy (SEM), and the elemental distribution was observed by using X-ray mapping and energy dispersive spectroscopy (EDS). The results showed that the pervaporation membrane of Geo-rGO-TiO2 (1, 3) achieved a permeate flux as high as 2.29 kg/m2·h with a salt rejection of around 91%. The results of the FTIR and XRD measurements did not show any changes in the functional group and chemical compositions of the membrane after the pervaporation process took place. Long-term pressure and temperature feed cause significant cracking in geopolymer and Geo-TiO2 (3) membranes. SEM results revealed that the surface of all membranes is leached out, and elemental distribution based on X-ray mapping and EDS observations revealed the addition of Na+ ions on the membrane surface. The study's findings pave the way for more research and development of geopolymers as the basic material for inorganic membranes, particularly with the addition of rGO-TiO2 nanocomposites.

Bandgap Variations and Photodegradation Efficiency on Inclusion of SiO2 in TiO2-rGO Nanocomposite for High Performance Photocatalysis

SiO2 is an excellent support material due to its flexible pore size and can be used as an adsorbent for the removal of toxic materials from water. Nanocrystalline TiO2-rGO is previously reported to show complete photodegradation for azo dyes. In pursuit of enhancing the adsorption capability of the system, we have incorporated SiO2 in TiO2-rGO nanocomposite which has drastically reduced the crystallinity of the matrix. Analysis of the bandgap variations is pursued here, which is crucial for enhanced light absorption and high performance photocatalysis.

Enhanced photodegradation toward graphene–based MgFe2O4–TiO2: Investigation and optimization

In this work, graphene–based MgFe2O4–TiO2 (MFO–TiO2@rGO) nanocomposite was synthesized and conducted an efficient photo–treatment with p–nitrophenol (PNP) as a well–known pollutant in water. The ternary material was characterized by modern analysis methods including Fourier transform infrared spectroscopy, X–ray diffraction, Raman spectroscopy, Transmission electron microscopy, Energy–dispersive X–ray spectroscopy, Selected area electron diffraction, and UV–vis spectroscopy. The simultaneous effects of the volume of H2O2, catalyst dosage, and pH on the photodegradation of p–nitrophenol were also examined by full factorial experimental design according to Box–Behnken designs. As a result, the characterization has confirmed the uniform bounding of MFO and TiO2 nanosizing from 4 to 6 nm on graphene with a high crystallinity degree. The photocatalysis of this material toward PNP can reach up to ∼99.44% in only 60 min reaction under UV control with 1.12 mL H2O2 added, 38.15 mg catalyst, and pH 9. Besides, in solar condition (directly under sun), the material also expressed a relatively impressive capability in degrade PNP from water. Furthermore, the ternary nanocomposite can be easily recycled and reused with an inconsiderable change in yield, represented by the elimination yield of recovered MFO–TiO2@rGO was significantly more than 90% after ten–run cycles. Indeed, the nanocomposite suggests an efficient pathway for treating organic contaminants in wastewater treatment.

Enhanced photocatalytic activity of reduced graphene oxide-TiO2 nanocomposite for picric acid degradation

The rGO-TiO2 nanocomposite was synthesised via a hydrothermal method. Numerous analytical and spectroscopic techniques have been used to characterise rGO-TiO2. The findings indicate that TiO2 has a tetragonal rutile phase and that TiO2 nanoparticles were densely packed on the GO sheet. In this study, the photocatalytic degradation of organic pollutant (picric acid) with rGO-TiO2 nanocatalyst linked with Fenton reagent [Fe 2+/H2O2] at various pH levels (3, 7 and 10) was investigated using UV light (wavelengths 254,265 and 395 nm), visible light, and sunlight. Among the various light irradiation conditions, visible light and sun light demonstrated the highest degradation efficiency due to the presence of rGO-incorporated TiO2 catalyst (rGO-TiO2 nanocompsite). Photolysis of picric acid of 200 mg/L was completed in 15 min and 18 min at the optimal pH of 3 and FeSO4·7H2O concentration of 1 mM, as well as the catalyst dosage of 50 mg/L under visible light and sun light. The rGO-TiO2 nanocomposite catalyst's superior adsorption and degradation properties make it an ideal solar-driven catalyst for organic pollutant degradation.

Immobilised rGO/TiO2 Nanocomposite for Multi-Cycle Removal of Methylene Blue Dye from an Aqueous Medium

This work presents the immobilisation of titanium dioxide (TiO2) nanoparticles (NPs) and reduced graphene oxide (rGO)-TiO2 nanocomposite on glass sheets for photocatalytic degradation of methylene blue (MB) under different radiation sources such as ultraviolet and simulated solar radiation. The TiO2 NPs and rGO-TiO2 nanocomposite were synthesised through a simple hydrothermal method of titanium isopropoxide precursor followed by calcination treatment. Deposition of prepared photocatalysts was performed by spin-coating method. Additionally, ethylene glycol was mixed with the prepared TiO2 NPs and rGO-TiO2 nanocomposite to enhance film adhesion on the glass surface. The photocatalytic activity under ultraviolet and simulated solar irradiation was examined. Further, the influence of different water matrices (milli-Q, river, lake, and seawater) and reactive species (h+, •OH, and e−) on the photocatalytic efficiency of the immobilised rGO/TiO2 nanocomposite was careful assessed. MB dye photocatalytic degradation was found to increase with increasing irradiation time for both irradiation sources. The immobilisation of prepared photocatalysts is very convenient for environment applications, due to easy separation and reusability, and the investigated rGO/TiO2-coated glass sheets demonstrated high efficiency in removing MB dye from an aqueous medium during five consecutive cycles.

Achieving of high utilization of reduced graphene Oxide-TiO2 nanoparticle composites via oxygen bonds for enhanced optical limiting performance

With the development of laser technology, the importance of laser protection has put an urgent demand for high-performance optical confinement materials. Herein, reduced Graphene oxide -TiO2 (rGO-TiO2) nanocomposites were rationally prepared by solvothermal method, and the rGO nanoparticles were homogeneously grown by oxygen bonding to improve the optical confinement properties. By using Z scanning system (1030 nm, 340fs), the nonlinear properties of rGO-TiO2 nanocomposites were measured to show theoretical nonlinear coefficients with 572.01 × 10−3 cm/GW, 136.17 × 10−3 cm/GW at 10.4 GW/cm2 and 20.8 GW/cm2, respectively, which are 5–20 times of pure GO. Furthermore, the normalized transmittance of the rGO-TiO2 nanocomposites reaches a minimum of 30%, showing that the materials have good nonlinear and optical limit (OL) properties, indicating that this work expands the choice of optical limit 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.

Titanium Dioxide Loaded Reduced Graphene Oxide Nanocomposite Film as Counter Electrodes for Dye-Sensitized Solar Cells

The demands on conventional fossil fuels are increasing especially developing countries. The growth of population among countries also put a lot of pressure on coil consumption and resulted effect of greenhouse. These phenomena will dramatically increase the global warming and pollutes the nature of earth. For the worse, it would forming some erratic patterns like flood, draughts, wildfire, and so on. Therefore, renewable solar energy is the key target to reduce the fossil fuel consumption, minimize global warming issues, and involuntary minimizes the erratic weather patterns. Dye-sensitized solar cell (DSSCs) is one of the promising prospects for efficient renewable resources. Most of the researchers were tried to use platinum as counter electrode to perform the photovoltaic studies. However, the platinum material will made higher for the entire fabrication cost. Recently, we demonstrated a counter electrode in DSSCs system using the low-cost titanium dioxide (TiO2) decorated reduced graphene oxide (rGO) nanocomposite film. The TiO2-rGO nanocomposite (TiO2-rGO NC) as counter electrode is addressed to minimize electron losses and hence rapid the rate of dye regeneration at ground state. Practically, TiO2-rGO NC synthesized via one-step hydrothermal method. The crystallinity, functional groups, element composition, and morphology of TiO2-rGO NC were comprehensively studied. One-step hydrothermal method revealed that Ti particles (∼60 nm) have capable bonded with rGO thin film, as agreement with XRD and FTIR results. In DSSCs photovoltaic performance, the optimized power conversion energy (PCE) of TiO2-rGO NC as counter electrode achieved a 2.90%, which achieved a desire performance as comparable with rGO and TiO2. In this work, the low-cost TiO2-rGO NC as counter electrode with suppressed recombination in DSSCs is studied.

Novel Silanized Graphene Oxide/TiO2 Multifunctional Nanocomposite Photocatalysts: Simultaneous Removal of Cd2+ and Photodegradation of Phenols under Visible Light Irradiation.

Reduced graphene oxide (RGO)-TiO2 nanocomposites have exhibited effective photocatalytic degradation of various organic pollutants. However, their poor solubility could limit their application in water and other organic solvents. In this study, new graphene-based cross-linked ethylenediaminetetraacetic acid (EDTA)-RGO-TiO2 (ERGT) nanocomposites were synthesized for the removal of Cd(II) and photodegradation of phenol from wastewater by surface-functionalized cross-linking heavy metal chelating agent sodium edetate (EDTA) and photocatalyst titanium dioxide. The structural properties of fabricated nanocomposites were characterized using SEM, TEM, XPS, FTIR, XRD, UV–vis, gas sorption, and Raman spectroscopy analyses. Moreover, the adsorption of Cd(II) and the degradation of phenol under different conditions were studied. The experimental results revealed that the optimal catalytic degradation and adsorption performance could be achieved at pH 5.5, and the maximum absorption ratio of cadmium ions and the degradation efficiency of phenol can reach 178.2 mg/g and 90%, respectively. The results suggested that ERGT is a potential material for the removal of threatening pollutants from wastewater.

Degradation of tetracycline in water by gas–liquid plasma in conjunction with rGO-TiO2 nanocomposite

Tetracycline (TC) is an antibiotic mainly used in livestock production and respiratory infection. Traditional methods are not effective in removing TC from solution. In this study, TC was degraded by gas–liquid plasma in the presence of rGO-TiO2 in solution. The rGO-TiO2 was prepared by modified hummers and hydrothermal method. The electrical and optical properties of the gas–liquid discharge plasma were studied and the produced long-lived reactive species were analyzed by spectrophotometer. The degradation efficiency of TC was improved by 41.4% after plasma treatment for 12 min in presence of 30 mg l−1 rGO-TiO2 compared to that with plasma alone. The degradation efficiency increased with increasing discharge power, but as the initial concentration was increased from 20 to 80 mg l−1, the degradation efficiency of TC decreased. The initial pH had no significant effect on the degradation of TC. The intermediate products were determined by UV–vis spectrophotometry and ESI (+)–MS, and the degradation mechanism was analyzed. The reactive species, including O3, ·OH, and H2O2, etc., produced in the plasma/catalyst system attracted electron-rich functional groups (amino group, aromatic ring, and double bond). Therefore, the gas–liquid plasma/catalyst system could be an effective and promising method for pharmaceutical wastewater treatment in future.

Preparation by Hydrothermal Method of TiO2-RGO Nanocomposite and Using as Photoanode of Dye-Sensitized Solar Cell

We explored the photoanode properties of DSSCs by used RGO and TiO2 nanoparticles as an optical electrode (we used the doctor's blade method). Using the hydrothermal process, we prepared a nanocomposite of TiO2/RGO. SEM and XRD, tests were used to study the structural properties of TiO2 and TiO2/RGO. When compared the J-V properties of the integrated devices made to those made, the J-V properties of the integrated devices came out on top of used TiO2/RGO as the photoanode in a solar cell for TiO2/RGO, which increased the PCE (8.674±0.063%). We were able to improve the short circuit current density (Jsc) and the power conversion efficiency (PCE) for the effective region by adding RGO to the TiO2. The PCE has improved due to better electron transport, improved electron collection in photoanode, and increased light-harvesting performance. As a result, RGO with distinct structural and optical properties is a viable choice in DSSC.

A Novel Electrochemical Sensor Based on Reduced Graphene Oxide–TiO2 Nanocomposites with High Selectivity for the Determination of Hydroxychloroquine

A simply sensitive sensor based on a reduced graphene oxide–TiO2 nanocomposite modified glassy carbon electrode (RGO–TiO2/GCE) was developed for the electrochemical determination of an antimalarial drug, hydroxychloroquine (HCQ). The modified electrode was characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Electrochemical test showed that the RGO–TiO2 electrode had stronger electrochemical activity and higher effective real surface area than that of TiO2 electrode and bare electrode. The electrochemical response of RGO–TiO2 nanocomposite modified electrode toward HCQ oxidation was studied by CV, chronoamperometry (CHA), chronocoulometry (CHC) and square-wave voltammetry (SWV). Interestingly, RGO–TiO2/GCE indicated an excellent electrocatalytic activity for HCQ. Under the optimal experimental conditions, a linear relationship between the peak current and the concentration was obtained, ranging from 0.25 to 500 μM, with the detection limit (S/N = 3) of 12.5 nM and quantification limit (S/N = 10) of 0.97 μM. Furthermore, the proposed sensor was successfully applied to the determination of HCQ in pharmaceutical (tablets) samples. In summary, the developed sensor was low cost and efficient, making it potentially attractive for practical sample analysis application of HCQ.

Enhanced gas sensing and photocatalytic activity of reduced graphene oxide loaded TiO2 nanoparticles

In the present study, we have evaluated the gas sensing and photocatalytic activity of reduced graphene oxide (rGO) conjugated titanium dioxide (TiO2) nanoparticles (NPs) formed by the hydrothermal method. The as-synthesized rGO-TiO2 nanocomposite were characterized for the physicochemical properties such as the nature of crystallinity, functionalization, and morphology by making use of the powder X-ray diffraction, Fourier transform-infrared spectroscopy, and scanning electron microscopy, respectively. On testing the gas sensing properties, we found that the rGO-TiO2 nanocomposite can serve as the chemoresistive-type sensor because of its sensitivity and selectivity towards different concentrations of hydrogen and oxygen at room temperature conditions. However, the rGO-TiO2 sensor’s response and recovery speed towards hydrogen and oxygen needs further optimization. Test of photocatalytic activity of TiO2-rGO catalyst for the removal of two model contaminant dyes, RhB and MB showed effective removal, with respective degradation percentages of about 80 and 90% within the first 50 min of irradiation under visible light irradiation. Besides, MB was more effectively degraded using TiO2-rGO than pure TiO2 during the first 30 min of irradiation and this enhanced activity can be attributed to the increased capacity of light absorption, the efficiency of charge carriers separation, and the specific surface area maintained by the rGO-TiO2 nanocomposite to effectively utilize the photo-generated holes (h+) and superoxide radicals (O2−), responsible for the degradation of the dye. Based on the overall analysis, the formation of rGO-TiO2 nanocomposite can significantly improve the gas sensing and photocatalytic properties of TiO2 NPs and thus can be potential for practical applications in future nanotechnology.

An environmental approach for the photodegradation of toxic pollutants from wastewater using silver nanoparticles decorated titania-reduced graphene oxide

Light-induced demineralization of organic pollutants is a recent development in the field of waste treatment. The present study focuses on TiO2-rGO-Ag hybrid nanocomposite through a two-step simultaneous synthesis pathway. The methods primarily involving facile solvothermal treatment (TiO2-rGO nanocomposite) in a water-ethanol mixture, followed by microwave irradiation method for deposition of silver (Ag) nanoparticles over the Binary nanocomposite synthesized. The resulting hybrid photocatalyst was well, and in-detail characterized using analytical techniques such as High-Resolution X-ray Diffractometer (HR-XRD), Transmission Electron Microscopy and High-Resolution Transmission Electron Microscopy (TEM/HR-TEM), High-Resolution Scanning Electron Microscopy (HR-SEM), Fourier-Transform Infra-Red Spectroscopy (FT-IR), Energy Dispersive X-Ray Spectroscopy (EDX), Raman Spectroscopy, Solid-State UV–Vis Spectroscopy and X-Ray Photoelectron spectroscopy (XPS). The nanomaterial was examined to determine photocatalytic property by conducting a photodegradation experiment of an aqueous solution of Methylene Blue (MB) dye and monitoring the changes. The photocatalytic efficiency of the nano-hybrid synthesized was also analyzed in detail for the degradation of compounds that active components of petrochemical pollutants such as Benzene, Toluene, and Phenol the Visible region of radiation in a photochemical reactor under ambient reaction conditions. The set of experiments suggested that the photocatalytic efficiency of ternary nanocomposite synthesized was quite noticeable. The variation in the catalyst's photoactivity with the change in the functional group was monitored, and the rate of reaction has been correlated with attached substituents.

Synthesis of TiO&lt;sub&gt;2&lt;/sub&gt;-rGO Nanocomposite and its Application as Photoanode of Dye-Sensitized Solar Cell (DSSC)

Dye-sensitized solar cells (DSSC) are solar cells that has a great potential to be applied as renewable energy conversion. The major advantages of DSSC are the ease of fabrication process and low cost of production. Despite of these advantages, the efficiency of DSSC for converting light into electricity is still low. It is due to charge recombination in DSSC which limits the photoanode performance. Numerous efforts has been carried out to increase the efficiency of DSSC, one of which is by adding reduced graphene oxide (rGO) to titanium oxide (TiO2) to obtain TiO2-rGO nanocomposite. In this study, the synthesis of TiO2-rGO nanocomposites was carried out with concentration of rGO are 0.6, 0.8, and 1.0 wt% to amount of TiO2. We have done some characterizations to confirm the result of synthesized TiO2-rGO. UV-Vis measurement shows the addition of rGO has widened the absorption up to 400 nm. The FT-IR spectrum confirms that the rGO peaks appears at wavelength of 1400, 1600, dan 1700 cm-1 which exhibited the vibration C-O, C=C, and C=O stretching from COOH groups, respectively. The highest efficiency of DSSC with photoanode TiO2-rGO nanocomposite is 0.09% which was obtained from 0.8 wt% of rGO.

Photonic split-second induced mesoporous TiO2-Graphene architectures for efficient sodium-ion batteries

Rechargeable sodium-ion batteries (SIBs) have received significant attention as a promising alternative to traditional lithium-ion counterparts for large-scale energy storage applications owing to the low cost and abundance of sodium resources. Herein, we demonstrate the photonic irradiated mesoporous reduced graphene oxide (rGO)-TiO2 nanocomposite architectures using environmentally benign, ultrafast split-second (millisecond) intense pulsed light (IPL) process at room temperature. The photonic IPL irradiation spontaneously triggers the deoxygenation of graphene oxide (GO) and the simultaneous structural engineering of TiO2 nanocomposites. The precisely controlled IPL irradiation (energy density of 10 J cm−2) exhibits excellent conductivity, high surface area, and outstanding electrochemical performance as a green anode material for SIBs. The photonic IPL irradiated rGO-TiO2 nanocomposite delivers a high reversible capacity of 244 mAh g−1 at 0.1 Ag-1, a high rate performance of 112 mAh g−1 at 1 Ag-1, and high cycling stability compared to pristine GO-TiO2 and conventional furnace annealed rGO-TiO2 (FH-rGO-TiO2) nanocomposites. The detailed electrochemical analysis suggests that the improved capacitance contribution results from the fast kinetics of the IPL irradiated rGO-TiO2 nanocomposite anode. This work provides new insight into the fabrication of versatile, cost-effective techniques for developing advanced electrode materials for energy applications.
