Tailored transition metal-doped TiO2@Fe3O4 nanohybrids for efficient photocatalytic dye removal: Optimization via neural networks and response surface approaches

The study focused on predicting the degradation of Remazol Turquoise Blue (RTB) dye using a photocatalyst comprised of transition metal-doped TiO2@Fe3O4. Out of the transition metal ions considered, namely Cu, Cr, Co, and Ni, Cr emerges as the most effective dopant for TiO2@Fe3O4 nanohybrid photocatalysts. This optimal performance was achieved with a catalyst loading of 50 mg and a dye concentration of 10 ppm within a 1-h reaction time, resulting in a photocatalytic efficiency of 96.70%. The optimization strategy employed a combination of Response Surface Methodology (RSM) and Artificial Neural Networks (ANN). To conduct experiments systematically, a Box-Behnken Design (BBD) rooted in RSM principles was utilized to create experimental setups for the photocatalytic degradation of the dye with the doped photocatalyst. The variables such as reaction time, catalyst dosage and dye concentration were designed to optimize the RTB dye degradation. The Regression coefficient (R2) for the developed RSM and ANN models were found to be 0.9299 and 0.9925 respectively, and revealed that the ANN has higher prediction capability and accuracy than other model. The outcomes underlined that the dosage of the catalyst prominently emerged as the principal determinant governing the efficacy of the photocatalytic activity. Remarkably, the Cr doped TiO2@Fe3O4 photocatalyst maintained its activity through six degradation cycles, with efficiencies of 99.7%, 99.4%, 99.1%, 88.8%, 87.3%, and 86.3%, respectively.

High-throughput screening of nano-hybrid metal-organic-frameworks for photocatalytic CO2 reduction.

Photocatalytic conversion of CO2 into fuel feed stocks is a promising method for sustainable fuel production. A highly attractive class of materials, inorganic-core@metal-organic-framework heterogeneous catalysts, boasts a significant increase in catalytic performance when compared to the individual materials. However, due to the ever-expanding chemical space of inorganic-core catalysts and metal-organic frameworks (MOFs), identification of these optimal heterojunctions is difficult without appropriate computational screening. In this work, a novel high-throughput screening method of nano-hybrid photocatalysts is presented by screening 65 784 inorganic-core materials and 20 375 MOF-shells for their ability to reduce CO2 based on their synthesizability, aqueous stability, visible light absorption, and electronic structure; the passing materials were then paired based on their electronic structure to create novel heterojunctions. The results showed 58 suitable inorganic-core materials and 204 suitable MOFs ranging from never-before-synthesized catalysts to catalysts that have been overlooked for their photocatalytic ability. These materials lay a new foundation of photocatalysts that have passed theoretical requirements and can significantly increase the rate of catalyst discovery.

Hydrogen produced from photocatalysis needs to be safely stored and transported. Containers make and material for effective hydrogen storage and transport needs to be identified in future. This review recommends the future directions to overcome the limitations of existing photocatalysts for simultaneous dye degradation and hydrogen production.

Electrochemical monitoring of congo red degradation using strontium titanate-doped biochar nanohybrids derived photocatalytic plates.

Present investigation demonstrates the development and characterization of strontium titanate (SrTiO3) doped biochar nanohybrid photocatalysts. Biochar nanohybrid was synthesized using an ultrasonic-assisted dispersion technique, which involved dispersing SrTiO3 nanoparticles into activated biochar at a weight ratio of 1:2 (w/w) under ambient conditions. The development of the biochar nanohybrid was verified through a comprehensive analysis of their spectral, microstructural, thermal, electrical, and electrochemical properties. The scanning electron microscopy analysis reveals a surface-associated multiphase morphology of the biochar nanohybrid, attributed to the uniform distribution of SrTiO3 within the activated biochar matrix. Biochar nanohybrid exhibited a reduced optical band gap of 2.77eV, accompanied by a crystallite size of 32.45. Thermogravimetric analysis revealed the thermal stability of the biochar nanohybrid, as evidenced by a char residue of 70.83% at 1000°C. The working electrodes derived from biochar nanohybrid have exhibited ohmic behavior and displayed a significantly enhanced DC conductivity (mS/cm) of 1.13, surpassing that of activated biochar (0.53) and SrTiO3 (0.62) at 100V. The developed biochar nanohybrid were employed for the degradation of congo red dye by exposing the dye solution to photocatalytic plates. These photocatalytic plates were prepared by coating biochar nanohybrid onto glass plates using epoxy-based reactive binders for secure binding. The photodegradation of congo red was evaluated through cyclic voltammetric analysis in a 0.1M KCl solution at pH 8.0, resulting in an impressive 99.95% photocatalytic efficiency in degrading a congo red solution (50mg/L). This study presents a novel approach for the fabrication of biochar nanohybrid-derived photocatalytic plates, offering high photocatalytic efficiency for the degradation of congo red dye.

Novel Bi2WO6/MWCNT nanohybrids synthesis for high-performance photocatalytic activity of ciprofloxacin degradation under simulated sunlight irradiation

In this research, novel Bi2WO6/MWCNT nanohybrids were synthesized via a cost-effective hydrothermal route. The photocatalytic performance of these specimens was tested through the photodegradation of Ciprofloxacin (CIP) under simulated sunlight. Various physicochemical techniques systematically characterized the prepared pure, Bi2WO6/MWCNT nanohybrid photocatalysts. The XRD and Raman spectra revealed the structural/phase properties of Bi2WO6/MWCNT nanohybrids. FESEM and TEM pictures revealed the attachment and distribution of plate-like Bi2WO6 nanoparticles along the nanotubes. The optical absorption and bandgap energy of Bi2WO6 was affected by the addition of MWCNT, which was analyzed by UV-DRS spectroscopy. The introduction of MWCNT reduces the bandgap value of Bi2WO6 from 2.76 to 2.46 eV. The BWM-10 nanohybrid showed superior photocatalytic activity for CIP photodegradation; 91.3% of CIP was degraded under sunlight irradiation. The PL and transient photocurrent test confirm that photoinduced charge separation efficiency is better in BWM-10 nanohybrids. The scavenger test indicates that h+ & •O2 have mainly contributed to the CIP degradation process. Furthermore, the BWM-10 catalyst demonstrated outstanding reusability and firmness in four successive cycles. It is anticipated that the Bi2WO6/MWCNT nanohybrids will be employed as photocatalysts for environmental remediation and energy conversion. This research presents a novel technique for developing an effective photocatalyst for pollutant degradation.

The surface morphology, crystalline structure, chemical composition, optical properties of the prepared samples was analysed by different various technique. The result observed analysis indicates that, the formation of heterojunction by 2:1wt% of FeWO4/FeS2 nanohybrid has the lowest recombination rate of electron-hole pairs and the least electron transfer resistance. Due to its the broad absorption spectral range and preferable energy band gap, the (2:1) FeWO4/FeS2 nanohybrid photocatalyst exhibits an excellent ability to remove MB dye when exposed to UV–Vis. Light irradiation. Its photocatalytic activity of (2:1) FeWO4/FeS2 nanohybrid is higher than other as prepared samples due to its synergistic effects, enhanced light absorption and high charge carrier separation. Radical trapping experimental result implies that the photo-generated free electrons and hydroxyl radials are essential to degrade the MB dye. Furthermore, a possible future mechanism for FeWO4/FeS2 nanocomposites photocatalytic activity was discussed. Moreover, the recyclability analysis demonstrated that the FeWO4/FeS2 nanocomposites can be recycled multiple times. The enhanced photocatalytic activity of 2:1 FeWO4/FeS2 nanocomposites is promising for the further application of visible light driven photocatalyst in wastewater treatment.

Novel ZnO/Ag nanohybrids prepared from Ag+-doped layered zinc hydroxides as highly active photocatalysts for the degradation of dyes and Ciprofloxacin

The design and the synthesis of highly active nanohybrid photocatalysts for environmental remediation is a topical issue in the context of sustainable development. The hybridization of a semiconductor with noble metal nanoparticles (NPs) has been demonstrated to be a versatile strategy to restrict the recombination of photogenerated electron-hole pairs and thus increase the photocatalytic activity. However, the uniform association of nanosized metal particles with ZnO NPs remains a challenge. Herein, a novel synthesis of ZnO NPs hybridized with Ag(0) NPs is presented. Ag+-doped layered zinc hydroxides (LZHs) were prepared in aqueous solution in the presence of triethanolamine and subsequently Ag+ ions were photoreduced into metallic Ag NPs embedded into LZHs. The LZHs not only promote the dispersion of Ag NPs but also limit their growth. The Ag(0)-doped LZHs obtained after hydrothermal treatment was finally transformed into ZnO/Ag nanohybrids by a mild thermal treatment at 300 °C for 5 min, which allows high interface coupling between ZnO and Ag NPs. ZnO associated with 3 mol% Ag exhibits the highest photocatalytic activity for the degradation of dyes (Rhodamine B and Remazol Brillant Blue R) and of the Ciprofloxacin antibiotic. The high photocatalytic performance of the ZnO/Ag(3) nanohybrid originates from the charge transfer in the ZnO/Ag nanohybrid and from the enhanced harvesting of visible light. The ZnO/Ag(3) photocatalyst also exhibits a high practical stability, indicating its great potential for real photocatalytic applications.

The significant environmental concerns need the extensive fabrication and design of efficient visible light responsive photocatalysts materials. The objective of this research is to develop a highly efficient ternary polyaniline – phosphotungstic acid @ZrO2 nanohybrid photocatalyst for use in visible light. polyaniline – phosphotungstic acid @ZrO2 nanohybrids were successfully synthesized by chemical oxidative polymerization method and characterized. The XRD analysis confirms the formation of monoclinic zirconia phase crystalline polymer while HR-SEM and HR-TEM results reveals that polymers were grown on the surface of Phosphotungstic Acid-Zirconia and contributes to visible light absorption property. The photocatalytic activity of Polyaniline (PANI)/Phosphotungstic acid (PTA)-Zirconia (ZrO2) nanohybrids was studied using methylene blue (MB) dye, p-Nitrophenol (PNP), 2, 4-dichlorophenoxyaceticacid (2, 4-D) as toxic pollutants.

Bandgap engineering approach for designing CuO/Mn3O4/CeO2 heterojunction as a novel photocatalyst for AOP-assisted degradation of Malachite green dye

A ternary nanohybrid CuO/Mn3O4/CeO2 was developed in the present work using a co-precipitation-assisted hydrothermal method. The designed photocatalyst's structural, morphology, elemental composition, electronic states of elements, and optical properties were studied using corresponding analytical techniques. Results from PXRD, TEM/HRTEM, XPS, EDAX, and PL showed that the desired nanostructure had formed. Using Tauc's energy band gap plot, it was determined that the nanostructures band gap was ~ 2.44 eV, which showed the band margins of the various moieties, CeO2, Mn3O4, and CuO, had modified. Thus, improved redox conditions led to a substantial decrease in the recombination rate of electron–hole pairs, which was further explained by a PL study in that charge separation plays a key role. Under exposure to visible light irradiation for 60 min, it was revealed that the photocatalyst achieved 98.98% of photodegradation efficiency for malachite green (MG) dye. The process of photodegradation proceeded according to a pseudo-first-order reaction kinetic model with an excellent rate of reaction of 0.07295 min−1 with R2 = 0.99144. The impacts of different reaction variables, inorganic salts, and water matrices were investigated. This research seeks to create a ternary nanohybrid photocatalyst with high photostability, visible spectrum activity, and reusability up to four cycles.

Enhanced Solar‐Photo(Electro)catalysis of Microwave‐Hydrothermal Synthesized BiVO4, ms‐BiVO4/Reduced Graphene Oxide/Ag3PO4 Nanohybrid: Crystalline Phase‐Dependent Interfacial Charge Carrier Dynamics

Bismuth vanadate with reduced graphene oxide (BiVO4/RGO) is prepared via ultrafast, energy‐efficient microwave‐assisted hydrothermal technique. Subsequently, Ag3PO4 nanoparticles are decorated on BiVO4/RGO by impregnated solution process. Photoelectrochemical (PEC) performance is carried out using as‐synthesized ternary heterostructure ms‐BiVO4/RGO/Ag3PO4 nanohybrid photoanode film and Pt‐wire as cathode in 0.5 m Na2SO4 electrolyte solution under AM 1.5 G (100 mW cm−2) irradiation. An enhanced photocurrent density of ≈3.6 mA cm−2 at +1.23 VRHE is observed for water oxidation, which is ≈2.3 times higher than pristine ms‐BiVO4 (1.58 mA cm−2). Furthermore, 10.1% of incident light‐to‐photocurrent conversion at λ = 450 nm and improved solar‐to‐hydrogen conversion efficiency of 4.5% with consistent photostability up‐to 24 h is achieved. While Rhodamine‐B dye degradation is investigated using BiVO4/RGO/Ag3PO4 photocatalyst, offers highest visible‐light‐driven photocatalytic (PC) degradation with average rate constant of kavg = 1.70 × 10−1 min−1 in 20 min, ≈4.3 times higher than pristine ms‐BiVO4. Such enhancement in PEC and PC performances is due to improved light absorbance coefficient with extended hole diffusion length (LPEC/PC = 209/147 nm) that enables efficient interfacial charge separation, transportation, and reduced photoinduced recombination. Herein, a strategy of designing an efficient nanohybrid photo(electro)catalyst to generate H2 fuel from water oxidation process and for environmental remediation is developed.

Photofixation of N2 to ammonia utilizing Ni@TPP-HPA nanocomposite under visible-light illumination.

The production of ammonia as an important raw material in the chemical, agricultural, and food industries has been always a significant concern. However, conventional ammonia production methods require high energy consumption and costs. The photocatalytic rotes use green light sources and cost-effective photocatalysts to obtain ammonia from water under aerobic conditions and preventing production of greenhouse gases in the environment. To produce an effective heterogeneous catalyst, a new tetraphenylporphyrin-heteropolyacid (TPP-HPA) nanohybrid material is synthesized and loaded onto Ni nanoparticles in this work. Then, FE-SEM, EDS, XRD, and FT-IR analyses were applied to characterize the prepared nanohybrid material Ni@TPP-HPA. After that, the new inorganic-organic nanohybrid photocatalyst was introduced as an effective, environmental friendly, and recyclable mediator for N2 photofixation. The results showed that Ni@TPP-HPA is a good photocatalyst for the N2 fixation reaction and can be easily recycled without losing its activity for at least five runs. The Ni@TPP-HPA nanocomposite demonstrated the maximum ammonia generation by 2760 μmol L-1 g-1 under mild conditions when using methanol as a hole scavenger. Additionally, effects of solvent type, temperature, reaction time, irradiation source, solution pH, and other electron scavengers on the rate of NH4+ production were investigated and discussed.

We report a facile synthesis of nitrogen and phosphorus co-doped carbon quantum dots (NPCQDs) anchored on ZnO nanorods to form NPCQDs/ZnO (NPCZ) nanohybrid as efficient and robust photocatalysts for light-driven hydrogen production. The synthesized NPCZ catalyst exhibited improvement in hydrogen production of 417 μmolh−1g−1 under visible light compared to nitrogen doped CQDs/ZnO (NCZ), phosphorus doped CQDs/ZnO (PCZ) and CQDs/ZnO (CZ) nanohybrid photocatalysts. The synergistic interactions between NPCQDs and ZnO nanorods give rise to the formation of additional energy levels, decrease in recombination rate and increase in decay lifetime of photo-generated electron hole pairs, reduced work function, thus the eventual improved hydrogen generation performance in visible region. Further, the experimentally obtained results are consistently corroborated by the first principles Density Functional Theory (DFT), revealing the decrease in bandgap as well as work function and improvement in density of states (DOS) of NPCZ photocatalyst.

Photocatalytic Degradation of Methyl Orange Dyes Using Green Synthesized MoS2/Co3O4 Nanohybrids

In this work, a new binary MoS2/Co3O4 nanohybrids was successfully fabricated and the chemical structures, morphologies, electrochemical and optical characterizations were carried out. In addition, heterojunction nanoparticles present in S-scheme structures act as electron traps and promote light absorption capacity for the degradation of Methyl orange (MO) with visible-light activity. MoS2/Co3O4 nanohybrids suggested excellent photocatalytic performance compared to bare MoS2 and Co3O4, where 95.6% of MO was degraded within 170 min, respectively. The results also showed excellent stability and recyclability over five consecutive cycles, without noticeable changes in the nanocomposite structure. The boosted photocatalytic degradation and redox activities of MoS2/Co3O4 can be attributed to the created S-scheme heterostructure to facilitate the separation of and to delay recombination of photoinduced charge carriers. We believe that this strategy of exploiting nanohybrid photocatalysts has great potential in the field of environmental catalysis and diverse applications.

A novel Ag/g-C3N4/ZnO/Fe3O4 nanohybrid superparamagnetic photocatalyst for efficient degradation of emerging pharmaceutical contaminant (Pantoprazole) from aqueous sources

Owing to their remarkable properties, such as concentration of energetic photons, scattering of photons and demonstration of surface plasmon resonance (SPR), the use of plasmonic noble metals in the construction of a nanohybrid photocatalyst holds great promise of enhancing photodegradation rates. The current work puts forth a facile route of fabrication of a robust Ag/g-C3N4/ZnO/Fe3O4 hybrid, superparamagnetic nano-photocatalyst for express photodegradation of pantoprazole, a prototype of a pharmaceutical.

Alone the photocatalyst achieved 98.24% disintegration of pantoprazole within 40 min with a stupendous pseudo-first order velocity constant of 0.10231 min−1. The performance of the quaternary photocatalyst was also evaluated in presence of various co-existing substances as well as in environmental water samples.

Sustainable visible light photocatalytic scavenging of the noxious organic pollutant using recyclable and reusable polyaniline coupled WO3/WS2 nanohybrid

Sustainable technology needs to be developed for tackling the critical environmental issues for viable development. The utilization of the natural visible light mediated photocatalysis for the decontamination of noxious chlorophenols could be an alternate method for wastewater purification. This work is focused on the fabrication of tungsten oxide (WO3)/disulfide (WS2) coupled polyaniline (PANI) (WO3/WS2/PANI) heterojunction nanohybrid photocatalyst for 2-chlorophenol (2-CP) decomposition in water. WO3/WS2/PANI nanohybrid photocatalyst was prepared via hydrothermal method using the L-Cysteine as a sulfurization agent. The bare WO3 and WO3/WS2 hybrid, WO3/WS2/PANI nanohybrid were characterized via UV–visible, photoluminescence, SEM, XRD, and XPS analysis methods. The coupling of PANI with WO3/WS2 created a synergistic effect on photocatalytic properties due to its better light-harvesting properties, and band gap energy suppression. Results discovered that the photocatalysis of 2-CP by the WO3/WS2/PANI is dependent on irradiation time, pH, and 2-CP concentration. The photocatalytic degradation increased from 83% to 100% with the decrease in initial 2-CP conc. from 50 mg/L to 10 mg/L. The photocatalytic degradation mechanism revealed that •O2−, •OH, and h+ reactive species are accountable for the decomposition of 2-CP by WO3/WS2/PANI nanohybrid and kinetic data was better fitted with the first-order kinetic model. The fabricated WO3/WS2/PANI catalyst exhibited excellent catalytic activity and reusability after five cycles, offering an active process for the degradation of toxic organic pollutants under visible light and sustainable technology for water remediation.

This research provides new insights for the preparation of high-efficiency graphene-based nano-hybrid photocatalysts with controllable structure through rational use of the structure-oriented and induced phase transition effects of graphene, and expands its visible light catalytic purification applications.

Fabrication of MnO2 nanowires and their nanohybrid with flat conductive matrix for the treatment of industrial effluents

In recent times, nanostructured semiconductive materials and nanohybrid with flat (2D) MXene sheets have gained considerable attention for photocatalytic applications. Here, we fabricated MnO2 nanowires (NWs, 1D) and their nanohybrid with MXene, as an innovative photocatalyst, to remove organic pollutants (organic dyes) and bacteria from industrial effluents. Indeed, MXene has excellent surface properties, owing to its flat structure. However, it's higher affinity to restack and oxidize is the problem that masks its other inherent features. We developed an innovative design to improve the stability of MXene and to reduce the resistivity and photocorrosion of semiconductive photocatalysts. The crystalline structure, morphology, specific surface area, thermal stability, and nanohybrid formation between MnO2 and MXene have been analyzed and confirmed via well-established conventional and advanced techniques. The prepared materials' photocatalytic and antimicrobial properties were evaluated under solar illumination using crystal violet (CV) dye and a Staphylococcus aureus(S.aureus) bacterial strain, respectively. Compared to pure MnO2 and MXene/MnO2 nanohybrid photocatalysts, H2O2-supported MXene/MnO2 nanohybrid demonstrated significantly greater photocatalytic activity for CV dye elimination. After 50 min of continuous illumination, the MXene/MnO2@H2O2 photocatalyst demonstrated approximately 91.5% dye degradation at a rate constant (0.045 min−1) higher than MnO2 (0.025 min−1) and MXene/MnO2 (0.029 min−1). The current work demonstrates that the MXene/MnO2 nanohybrid photocatalyst is capable of photodegrading dyes efficiently and inhibiting the rapid growth of microbes found in industrial discharges.
