Enhanced photocatalytic efficiency of BaTiO3 augmented by ZnS nanospheres via Type-II heterojunction for methyl orange degradation

The degradation of organic pollutants is significantly influenced by the recombination of photogenerated electron–hole pair, electron transfer and surface area of a photocatalyst. Barium titanate (BaTiO3) exhibits low photocatalytic activity due to the rapid recombination of photoinduced charge carriers. Hence, the photocatalytic performance of BaTiO3 (BTO) nanoparticles was improved by the construction of heterostructure with the addition of ZnS. BaTiO3 and ZnS were prepared using solid-state metathesis (SSM) and hydrothermal methods, respectively. Subsequently, a series of [(1-x)BaTiO3/(x)ZnS, x = 10, 30, 50 and 70 wt%] heterostructures were successfully constructed through a simple calcination method using pre-prepared BaTiO3 and ZnS. The XRD, FTIR, Raman, XPS and HRTEM analyses revealed the formation of heterostructure between the BTO and ZnS. The positron annihilation lifetime spectroscopy (PALS) results suggest the existence of defects within the materials. To explore the photocatalytic activity, the photodegradation of methyl orange (MO) dye was carried out under UV light illumination for 3 h. Among all the compositions, the heterostructure 70 BaTiO3/30 ZnS (BTZS(70-30)) demonstrated remarkable photocatalytic activity (91.38 %) which is 5.3 times higher than the pristine BTO (17.16 %). The improved photocatalytic activity of heterostructures may result from the effective charge carrier separation facilitated by the type –II band alignment structure between BTO and ZnS, as well as surface defects like oxygen (Vo), and sulphur (Vs) vacancies. The lowest photoluminescence of BTZS (70-30) clearly substantiated the observed high photocatalytic activity. The scavenger outcomes validated that superoxide radicals (•O2−) and holes (h+) played predominant role in the degradation of MO and a detailed explanation was provided for the plausible mechanism.

Carboxylate bridging Cd(II)-based 1D coordination polymer: Structure, fabrication of Schottky device and selective sorption of Bromocresol Green

Phenyl-1,3-diacetate (1,3-PDAt) bridging Cd(II)-based 1D coordination polymer {[Cd(1,3-PDAt)(phen)]⋅(MeOH)⋅(H2O)0.5}n, (CP) where 1,10-phenanthroline (phen) serves as chelating ligand has been structurally confirmed by Single Crystal X-Ray Diffraction measurements along with other spectral data. The thermal treatment releases MeOH at ∼90 °C and the final product ends at CdO. The Tauc’s plot evaluates the band gap, 3.87 eV (calculated value, 3.76 eV) using absorption spectral data which marks the semiconducting nature of the material. This has motivated us to fabricate Schottky Diode device and the measured conductance is 8.87 × 10−6 S/m in the dark. Interestingly, 1D CP shows selective and specific sorption of Bromocresol Green (BG) out of four common dyes (Methylene blue, Methyl orange, Rhodamine B, and Bromocresol Green (BG)). Besides, the sorbed BG in the CP is leached out on treating with water and the CP has been re-used for further sorption studies. Thus, the CP is economically recycled which is the first principle of Sustainable Development Goals.

Green synthesis of silver nanoparticles from waste leaves of tea (Camellia sinensis) and their catalytic potential for degradation of azo dyes

Tea leaves are discarded after use as waste material. An attempt was made to explore the potential of tea waste as an alternative source of extensive reducing agent for green and biocompatible synthesis of silver nanoparticles (WT-AgNPs) from silver nitrate salt, and prospective utilization for degradation of toxic azo dyes such as methyl orange and Congo red occurring in effluents. Green tea extract was also used as reducing agent to synthesize AgNPs (GT-AgNPs) to compare their physicochemical properties and efficiency vis-à-vis WT-AgNPs. Both WT-AgNPs and GT-AgNPs were characterized by Ultraviolet-Visible (UV) and Fourier Transform Infrared (FTIR) Spectroscopy, particles size and zeta potential measured by Dynamic Light Scattering (DLS), surface morphology and elemental composition determined by Field Emission Scanning Electron Microscopy (FESEM). The average particle size, zeta potential and surface plasmon resonance (SPR) were 74.85 nm, -22.62 mV, 422 nm and 69.53 nm, -21.28 mV, 420 nm for WT-AgNPs and GT-AgNPs, respectively. Catalytic degradation reaction of methyl orange and Congo red using the biogenic AgNPs followed the pseudo-first order kinetics in both cases. The rate constants of methyl orange dye (100 ppm) degradation using the catalysts (WT-AgNPs and GT-AgNPs) were 0.087 s−1(R2=0.922) and 0.099 s−1 (R2=0.963) respectively, showing 93 % and 95.5 % degradation of dye in 40 min in presence of NaBH4. For Congo red (100 ppm) degradation, the rate constants were 0.112 s−1 (R2=0.917) and 0.113 s−1(R2=0.943). Both WT-AgNPs and GT-AgNPs exhibited bacteriostatic effect inhibiting growth of E. coli. The study offers potential use of waste tea leaves as an effective reducing agent for large-scale green synthesis of silver nanoparticles having multifarious environmental applications in general, dye degradation and antibacterial action in particular.

Towards a profound understanding of methyl orange removal from industrial wastewater using a raw walnut shell: Kinetics, equilibrium, thermodynamics, and statistical physics calculations

The present study investigates the adsorption of the anionic dye methyl orange (MO) using raw walnut shells (RWS). Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy techniques were used to evaluate RWS collected in the Moroccan High Atlas (Tounfite) highlands. The batch mode adsorption experiments showed a remarkable removal during the first ten minutes, suggesting that the adsorption capacity is controlled by several parameters related to both the medium and the adsorbent. Based on the experimental results, 98 % of the MO dye was adsorbed on the walnut shell at pH >5 and room temperature (25±2 °C). The general order best explained the adsorption of MO on the walnut shells, suggesting that the number of active sites required changes with temperature. The two-layer model was the most appropriate physical-statistical model to explain the L-2 isotherms regarding the adsorption equilibrium. According to the models, methyl orange tends to be adsorbed on the surface of the monolayer, with individual molecules then adsorbing on top of each other. At all temperatures studied, the adsorption is endothermic and tends to be spontaneous, according to simulations of thermodynamic functions of RWS.

Characterization and Photocatalytic Activity of Er2Ti2O7 Prepared by Sol-Gel Method

In this article, the erbium nitrate pentahydrate (Er(NO3)3·5H2O), tetrabutyl titanate (C16H36O4Ti), glacial acetic acid (CH3COOH), and anhydrous ethanol (C2H5OH) were used as the main raw materials. The Er2Ti2O7 was successfully prepared by the sol-gel method. The structure and morphology of the samples were characterized by thermogravimetric-differential thermal analyzer (TG-DSC), X-ray diffractometer (XRD), scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FT­IR). The 10 mg/L methyl orange solution was used as a simulated pollutant under UV light conditions. The effects of different temperatures and light times on the photocatalytic performance of the Er2Ti2O7 samples were investigated. The results showed that the pure Er2Ti2O7 samples could be successfully prepared by calcination in the temperature range of 750–1000 °C. The average grain size of Er2Ti2O7 was about 20–60 μm, and the photocatalytic performance of Er2Ti2O7 samples calcined at 900 °C was the best. When the illumination time is 90 min, the degradation rate of methyl orange reaches to about 100%. The preparation of Er2Ti2O7 by the sol-gel method is a kind of ultraviolet light photocatalyst with wide application prospects.

Modulating photocatalytic activity of nitrogen doped TiO2 nanoparticles via magnetic field

The effect of the magnetic field on the photocatalytic activity of TiO2-based nanoparticles is analyzed using a magnetically-assisted photoreactor with permanent magnets to generate a controlled uniform magnetic field, B (≈ 82 mT). Nitrogen doped TiO2 nanoparticles (sizes around 10 nm) were synthesized through a solvothermal method employing Ti(IV) butoxide and HNO3 (x = 0, 0.5, 1, 1.5 and 2 mL) as precursors and their structural, optical and magnetic properties were analyzed. Specifically, nitrogen doping is confirmed through Hard X-ray Photoelectron Spectroscopy (HAXPES) in those samples synthesized with low HNO3 concentrations (x = 0.5, 1). The correlation between spin polarization (magnetic susceptibility) and visible photocatalytic activity (methyl orange as a model organic pollutant) is particularly analyzed. Surprisingly, opposite effects of the magnetic field on the photocatalytic performance are found in the visible range (above 400 nm) or under UV-Vis irradiation (decrease and increase in the photocatalytic activity, respectively, under magnetic field). The Langmuir-Hinshelwood model allows us to conclude that the strong decrease in adsorption under the magnetic field (around 42 % for x = 0.5) masks the increase in the kinetic constant (close to 58 % for x = 0.5) related mainly to the effect of Lorentz forces on the reduction of the electron-hole recombination.

A novel hierarchical porous CoFe2O4-SiO2@GA composite and the solar-Fenton synergistic degradation of mixed dyes

A novel CoFe2O4-SiO2@rGO aerogel composite (CFO-S@GA) was synthesized via facile solvothermal methods. SiO2 and graphene act as co-matrixes and exhibit complementary effects, improving the CFO's dispersion and constructing the hierarchical porous structure of CFO-S@GA. CFO-S@GA achieved superior degradation performance of 99.1 %, 99.8 %, and 90.6 % removal ratio for Methylene Blue (MB), Rhodamine B (RhB), and Methyl Orange (MO) in 30 min under simulated solar irradiation, respectively. The degradation is adaptive to a wide pH range (2.4–10.1) and low H2O2 consumption (500 μL/L). CFO-S@GA could even rapidly decolor high chroma mixed dye wastewater under natural solar irradiation within 110 min by adding the bulk material without stirring. The excellent performance was attributed to the photo-Fenton synergistic degradation of CFO-S@GA. The reactive oxygen species OH•, O2•−, and 1O2 were demonstrated to play the leading role in the solar-Fenton synergistic system. Additionally, the bulk CFO-S@GA showed outstanding stability and reusability during recycling experiments.

A ternary composite nanofibrous photocatalyst: FcLR-gC3N4/polyisothianaphthene/polyacrylonitrile for degradation of organic dyes

BackgroundWater pollution by organic dyes is one of the important environmental issues. When substances such as organic dyes are discharged into water, they can severely pollute the water and harm the life of living organisms. MethodsA new ternary composite nanofibrous photocatalyst, FcLR-gC3N4/PITN/PAN, was produced through 1) synthesis of a graphitic carbon nitride (g-C3N4)-based ferrocenyl dithiophosphonic acid, FcLR-gC3N4, by the attachment of Ferrocenyl Lawesson's Reagent (FcLR) to g-C3N4 nanosheets, 2) incorporation of the FcLR-gC3N4 into the polymeric matrix of as-prepared polyisothianaphthene (PITN) blending with polyacrylonitrile (PAN), and 3) fabrication of electrospun nanofibers (NFs) through electrospinning. Significant findingsThe degradation of methyl orange (MO) and methylene blue (MB) was more efficient on FcLR-gC3N4 compared to g-C3N4 alone, and on FcLR-gC3N4/PITN/PAN compared to FcLR-gC3N4, confirming the effective role of both FcLR and PITN/PAN matrix in the degradation of the dyes. The ternary composite nanofiber degraded 92% of MB and 29% of MO. The MB mineralization percentages of 65% (TOC), 60% (COD), and 55% (BOD) were achieved after 2 h and 30 min. Radical trapping experiments consistent with the Tauc plots and Mott-Schottky plots distinguished O2•- as the primary species in the degradation mechanism of MB. The MB degradation pathway was determined through LC-MS-MS. The electrochemical impedance spectrum (EIS) and photocurrent measurements confirmed the higher photocatalytic activity of FcLR-gC3N4 compared to g-C3N4 alone by studying the charge carrier's separation and recombination. A high recyclability was found for FcLR-gC3N4. The recycling stability of FcLR-gC3N4 increased after its embedding into the nanofibrous matrix of PITN/PAN.

Facile in-situ fabrication of graphene oxide/poly(ionic liquid) composites and their adsorption performance for methyl orange

This work reveals a facile in-situ fabricating strategy for graphene oxide/poly(ionic liquid) composites toward the effective adsorption of methyl orange in aqueous solution. This synthetic route includes the formation of novel surfactant-free ionic liquid microemulsions and the stable solubilization of graphene oxide. To characterize the designed composites, FTIR, XRD, TGA, SEM, DSC, and XPS analyses were conducted, and the adsorption isotherms/kinetics of the designed composites toward methyl orange were further investigated. Results indicated that graphene oxide/poly(ionic liquid) composites can be in-situ synthesized facilely within the surfactant-free ionic liquid microemulsions, and the network structure of composites can be adjusted effectively by altering the dosage of co-solvent. In addition, the graphene oxide/poly(ionic liquid) composites prepared in situ exhibited a remarkable adsorption performance of methyl orange. These findings indicate the great application potential of graphene oxide/poly(ionic liquid) composites in the field of cationic dye adsorption.

Photothermal effect improving the activity of spinel MnFe2O4 nanoparticles for the catalytic activation HCO3−/H2O2 to achieve the degradation of dye pollutants in low-temperature condition

Based on the features of Mn/Fe bimetallic sites and photothermal property, spinel MnFe2O4 nanoparticles were investigated to activate HCO3−/H2O2 for the degradation of methyl orange (MO), methylene blue (MB) and rhodamine B (RhB). Compared to Mn3O4, MnO2 and Fe2O3- activated HCO3−/H2O2 systems, higher degradation rate of dyes was achieved in the spinel MnFe2O4/HCO3−/H2O2 system at 23 ± 2 °C, due to the Mn/Fe bimetallic active sites of spinel MnFe2O4. Meanwhile, the spinel MnFe2O4 nanoparticles had high stability in HCO3−/H2O2 activating for dyes degradation in 15 rounds of reaction. The co-existing ions and hardness in municipal tap water had weak influence on the HCO3−/H2O2 activating activity of spinel MnFe2O4 for dyes degradation at 23 ± 2 °C. More interestingly, although the dyes degradation activity of MnFe2O4/HCO3−/H2O2 system at low-temperature (3 ± 2 °C or 13 ± 2 °C) was weakened, the system activity at low-temperature can be obviously boosted through AM 1.5 G irradiation to activate the photothermal effect of spinel MnFe2O4. Additionally, the MnFe2O4/HCO3−/H2O2 system exhibited good practicability for dyes degradation in a 15 L of continuous reactor. In mechanism, the degradation of MB in spinel MnFe2O4/HCO3−/H2O2 system was found to be co-driven by 1O2 and OH, and the degradation of RhB and MO was co-initiated by O2−, OH and CO3−.

A novel graphene-N/TiO2-nickel foam: Preparation and application in photoelectric synergistic degradation of methyl orange

Photoelectric synergistic degradation of dye wastewater has been developed. In this experiment, we prepared Nitrogen-doped titanium dioxide-graphene/nickel foam (N/TiO2-Gr/F–Ni) by electrophoresis and impregnation methods, to degrade methyl orange (MO) aqueous solution. Firstly, nitrogen-doped titanium dioxide particle (N/TiO2) was prepared by the sol-gel method, which showed a photocatalytic degradation catalytic kinetic constant of 1.8 × 10−2 min−1 under simulated sunlight. Meanwhile, graphene (Gr) was loaded on nickel foam (F–Ni) to prepare Gr/F–Ni electrode by electrophoresis method, which obtained a catalytic kinetic constant of 1.15 × 10−2 min−1 at 10 V. Finally, N/TiO2 was loaded on Gr/F–Ni to prepare N/TiO2-Gr/F–Ni photoelectrode by electrophoresis and impregnation methods, which had a catalytic kinetic constant of 3.96 × 10−2 min−1 at 10 V and under 1 sun. The results show that there is a synergistic effect between light degradation and electro-Fenton oxidation because the bonding electrons in N/TiO2 are activated to produce photogenerated electron-hole pairs. On the other hand, the separation efficiency of the photogenerated electron is enhanced by the Gr.

Exploring the Anti-Corrosion, Photocatalytic, and Adsorptive Functionalities of Biogenically Synthesized Zinc Oxide Nanoparticles

This study reported the synthesis of ZnO nanoparticles (ZnO NPs) using Cucurbita pepo L. seed extract and explored their multifunctional properties such as anti-corrosion, photocatalytic, and adsorption capabilities. The synthesized ZnO NPs were characterized by Fourier-transform infrared spectroscopy (FTIR) to identify their functional groups, thermogravimetric analysis (TGA) to assess their thermal stability, transmission electron microscopy (TEM), and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX) to determine their size, morphology, and elemental composition. The characterization of biofabricated ZnO NPs revealed an average particle size of 32.88 nm; however, SEM displayed a tendency for the particles to agglomerate. Furthermore, the X-ray diffraction (XRD) and EDX analysis confirmed the NPs as ZnO, matching patterns reported in the literature. In this study, the potential of the biogenic ZnO NPs was explored for multifunctional applications. Zinc oxide nanoparticles exhibited a higher capacity for adsorbing hydrogen sulfide (H2S) compared to bulk zinc oxide, mostly because of their larger surface area. In addition, electrochemical studies demonstrated a substantial enhancement in the corrosion resistance of mild steel in a 1.0 M HCl solution. ZnO NPs also demonstrated remarkable photodegradation effectiveness, reducing 75% of methyl orange in 60 min under sun-light irradiation. This implies that they could be used to remediate organic pollutants (organic dyes) from wastewater.

Effect of Solvothermal Time to Characteristics and Performance of Photocatalyst Bismuth‐Rich Oxyiodide for Dye Decolorization

AbstractThis study aims to explore how altering solvothermal duration influences the characteristics of the resulting products, spanning crystal structure, band gap energy, morphology, and photocatalytic performance. Bismuth‐rich oxyiodide was synthesized via the solvothermal method by dissolving Bi(NO3)3 ⋅ 5H2O and KI in ethylene glycol. The mixture underwent heating in a Teflon autoclave stainless steel at 120 °C for durations of 6, 12, 24, and 48 hours. Analysis using FTIR revealed the presence of Bi−O and I−O bonds. Diffractograms indicated that all products exhibited traits of Bi4O5I2, with slight traces of Bi5O7I. Distinct band gap energies were observed across the solvothermal durations: 2 eV for 6 hours, 2.08 eV for 12 hours, and 1.89 eV for both 24 and 48 hours, delineating temporal nuances in product properties. Noteworthy, the morphology of the 12 hour variant revealed surface pores, indicative of intricate structural features. Notably, the 12 hour product exhibited the pinnacle of photocatalytic efficacy in methyl orange decolorization under UV light. Furthermore, investigations into photocatalyst mass variations and the inclusion of additional dyes, such as rhemazol black B, further elucidated the robust photocatalytic potential inherent in the B12 variant.

Mechanistic insight into enhanced methyl orange degradation by Raoultella planticola/MoS2 biohybrid: Implication for electron transfer and microbial metabolism

The biodecolorization of traditional azo dyes is typically hindered by low electron transfer rate, a challenge that can be addressed by incorporating nanoparticles with redox properties to establish a stable biohybrid system. Here, a surface precipitated R. planticola/MoS2 biohybrid characterized by excellent biocompatibility was developed. The findings revealed that hybrid molybdic sulfide (MoS2) at concentrations ranging from 0.1 to 0.7 mM facilitated the biodecolorization of methyl orange (MO), with the R. planticola/MoS2(0.5mM) exhibiting the highest decolorization efficiency. The levels of nicotinamide adenine dinucleotide (NADH), adenosine triphosphate (ATP) in the R. planticola/MoS2 biohybrid increased by 92.08%, 42.61%, respectively, indicating a significant enhancement in microbial metabolic activity. Moreover, the electron transfer system activity (ETSA) of the biohybrid increased by 85.89%, accompanied by a decrease in charge transfer resistance, while MoS2 may involved in and contributed to a notable improvement in the electron transfer capability of the system. Structural equation modeling analysis showed a significant correlation between the R.planticola/MoS2 with extracellular polymeric substances (EPS) and antioxidant stress capacity, with standardized path coefficients of 0.837 and 0.999, respectively, indicating enhanced environmental adaptability of R. planticola. Even after 4 cycles of decolorization, the efficiency remained above 90%, demonstrating good stability. This study comprehensively elucidated the synergistic promotion mechanism of the R. planticola/MoS2 in enhancing MO biodegradation through enhancements in microbial metabolic activity and electron transfer capacity. The findings present a novel strategy for accelerating the biodecolorization of azo dyes and deepening the understanding of the interactions between nanomaterials and microorganisms.

Z-scheme based photoactive ZnO:TiO2:CdO:g-C3N4 nanocomposites for advance oxidation process

Z-scheme-based hybrid [(ZnO0.40:0.60TiO2):CdO1.00]:g-C3N4] nanocomposites (NCs) were synthesized by sol-gel precipitation and thermal polycondensation methods. Microscopic FE-SEM images varied from a compact crystal-like structure to a mesoporous sheet-type structure. XRD patterns confirmed the polycrystallinity for all samples. Meanwhile, the g-C3N4 interacts extensively with Zn+2 and Cd+2. The optical bandgap increased from 2.12 eV to 2.25 eV with the addition of g-C3N4 concentration. Z-scheme [(ZnO0.40:0.60TiO2):CdO1.00]:[g-C3N4] NCs of the particular composition named ZTCG4 showed the highest photocatalytic activity and degraded the methylene blue (MB), methyl green (MG), and methyl orange (MO) to be 99.7 %, 99.8 %, and 99.9 %, respectively, under the illumination of the visible light. Mineralized factors: chemical oxygen demand (COD) and biochemical oxygen demand (BOD) achieved the maximum removal efficiencies of 89.4 % and 88.9 % for the sample g-C3N4. Prepared photocatalysts can be utilized to remove the organic pollutants from the drainage systems under visible light exposure.

Biphasic Mo-based catalysts with abundant pores and rich heterostructures for high-efficient production of hydrogen in both alkaline and acidic media

Electrolysis of water to produce H2 demands high-efficient catalysts. Herein, biphasic γ-MoC/MoS2/C electrocatalyst with heterostructures was prepared using methyl orange as the low-cost C and S resource. The γ-MoC/MoS2/C presented convoluted nanosheets with abundant pores and rich heterostructures, which owed it excellent catalytic performance in both of 1 M KOH and 0.5 M H2SO4 solutions. The overpotentials required to reach 10 mA·cm−2 were 58 mV and 81 mV, respectively, under alkaline and acidic conditions. γ-MoC/MoS2/C also exhibited satisfactory long-term stability, that negligible decrease of the LSV curves was observed after 3000 CV cycles. The current density was maintained at approximately 95 % and 91 % in 1 M KOH and 0.5 M H2SO4 solutions, respectively, over 36 h. DFT results showed that the ΔGHads* value of γ-MoC/MoS2/C is −0.12 eV, approaching to zero, which is conducive to the adsorption and desorption of Hads* and thus promotes the hydrogen evolution reactions (HER). The synthesis of γ-MoC/MoS2/C was quite facile and flexible, which avoid stepwise carbonization and sulfuration. It is expected to provide a fresh reference for the synthesis of high-efficient, low-cost and susceptible Mo-based catalysts.

Synthesis of carbon nanotube–iron oxide and silver nanocomposites as photocatalyst in removing carcinogenic aromatic dyes

Abstract In this research, a three-component composite was synthesized by using carbon nanotube as the background phase. Iron oxide phase with high magnetization and low coercivity (with particle size of 200 nm) has been coated on the carbon nanotubes. Then, the silver nanoparticles were coated on a conductive and magnetized substrate by an ultrasonic method. Semiconductor photocatalys is a favorable route for the degradation of organic pollutants. Ultraviolet–visible spectrophotometry has been used to investigate the photocatalytic properties of synthesized nanocomposite and control of their dye degradation on methyl blue, methyl orange and methyl red. The obtained nanocomposite is easily collected due to its magnetic property and does not pose a risk to environmental waters. The dye degradation degree has been compared for the produced nanocomposite. The experimental results confirmed that methyl red shows the greatest amount of degradation within 1 h, which was about 90 %, methyl orange shows about 80 %, and methyl blue shows the lowest degradation, around 60 %.
