The Enhancement Light Absorption of ZnO-TiO2 Nanocomposite as Photoanode

ZnO nanomaterial in Dye Sensitized Solar cells (DSSC) has the disadvantage of low efficiency. The purpose of this study was to improve the DSSC efficiency of the ZnO photoanode. ZnO-TiO2 nanocomposites are used as photoanodes that can improve light absorption. ZnO-TiO2 nanocomposites can increase the performance efficiency of the solar cell compared to ZnO Pristine. This is due to the reduced recombination between ZnO/electrolyte and the increased lifetime of electrons because of the presence of electrons trapped in TiO2. The most optimal sample from this study was found in ZnO-TiO2 nanocomposite with a volume concentration ratio (85%-15%) because the efficiency DSSC increases almost 2 times.

Synthesis, Photocatalytic and Bio Activity of ZnO-TiO2 Nanocomposites: A Review Study

Zinc oxide and titanium dioxide are materials with strong photocatalytic and antimicrobial activity. This activity is greater when the material is in nanocrystalline form. It has been seen that these properties are also present in the ZnO-TiO2 nanocomposite material, and the extent depends on multiple factors, such as crystallinity, structural composition, crystallite size, and morphology. These structural properties can be varied by acting on the synthesis of the material, obtaining a wide variety of composites: random nanoparticles, nanorods, nanowires, nanotubes, nanofibers, tetrapods, core–shell, hollow spheres, inverse opal structures (IOSs), hierarchical structures, and films. When an interface between nanocrystallites of the two oxides is created, the composite system manages to have photocatalytic activity greater than that of the two separate oxides, and in certain circumstances, even greater than P25. The antimicrobial activity results also improved for the composite system compared to the two separate oxides. These two aspects make these materials interesting in various fields, such as wastewater and air treatment, energy devices, solar filters, and pharmaceutical products and in the context of the restoration of monumental cultural assets, in which their use has a preventive purpose in the formation of biofilms. In this review we analyse the synthesis techniques of ZnO-TiO2 nanocomposites, correlating them to the shape obtained, as well as the photocatalytic and antimicrobial activity. It is also illustrated how ZnO-TiO2 nanocomposites can have a less negative impact on toxicity for humans and the environment compared to the more toxic ZnO nanoparticles or ZnO.

Photocatalytic ozonation-based degradation of phenol by ZnO–TiO2 nanocomposites in spinning disk reactor

Spinning disk reactor (SDR) has emerged as a novel process intensification photocatalytic reactor, and it has higher mass transfer efficiency and photon utilization for the degradation of toxic organic pollutants by advanced oxidation processes (AOPs). In this study, ZnO–TiO2 nanocomposites were prepared by sol-gel method, and coated on the disk of SDR by impregnation-pull-drying-calcination method. The performance of catalyst was characterized by X-ray diffraction, scanning electron microscope, X-ray photoelectron spectroscopy, photoluminescence and ultraviolet–visible diffuse reflectance spectroscopy. Photocatalytic ozonation in SDR was used to remove phenol, and various factors on degradation effect were studied in detail. The results showed that the rate of degradation and mineralization reached 100% and 83.4% under UV light irradiation after 50 min, compared with photocatalysis and ozonation, the removal rate increased by 69.3% and 34.7%, and mineralization rate increased by 56.7% and 62.9%, which indicated that the coupling of photocatalysis and ozonation had a synergistic effect. The radical capture experiments demonstrated that the active species such as photogenerated holes (h+), hydroxyl radicals (·OH), superoxide radical (·O2−) were responsible for phenol degradation, and ·OH played a leading role in the degradation process, while h+ and ·O2− played a non-leading role.

Annealing-induced enhancement of TiO2-ZnO nanocomposites for high-performance room-temperature air pollutant detection in fiber optic sensors

Fiber optic sensors, promising for their compactness and remote sensing abilities, are explored in this study as a platform for detecting volatile organic compounds (VOCs) using nanocrystalline metal oxide composites like TiO2-doped ZnO. Hydrothermally synthesized (S1 sample)and annealed composites (500 °C (S2 sample) and 1200 °C (S3 sample) annealing) were investigated for their gas-sensing properties towards inorganic gas like ammonia and VOCs like acetone, and isopropyl alcohol. Remarkably, annealing at 1200 °C yielded S3 sample with higher response (7.5 %) towards ammonia at room temperature for 500 ppm concentration. This superior performance is attributed to increased surface area, narrowed bandgap, and faster response/recovery times (18/15 s) compared to other samples. The proposed sensing mechanism involves the adsorption and desorption of oxygen molecules on the sensor surface, altering refractive index and light scattering, ultimately modulating the transmitted light intensity. X-ray diffraction, SEM imaging, and UV–Vis absorption techniques confirmed the structure and morphology of the nanocomposites.

MXene derived TiO2–ZnO nanocomposites and well-defined n-n heterojunctions for highly efficient lung cancer biomarkers detection

Enhancing the sensing properties of resistive sensors holds pivotal importance as a non-invasive technology for identifying lung cancer biomarkers. This study focused on the development of a robust sensing platform to effectively detect low-concentration biomarkers with low concentration. Ti3C2Tx MXene was prepared by HF etching and ZnO was successfully grown on the MXene nano-multilayers via hydrothermal method subsequently. TiO2–ZnO samples were obtained after the calcination step. Various characterization methods were applied to validate the structural integrity and formation of the TiO2–ZnO n-n heterojunction. The TiO2–ZnO sensor with a Ti:Zn atom ratio of 1:1 (TZ1) exhibited special sensing characteristics, which can be attributed to the higher activation energy (89.2 kJ/mol) and the more substantial interfacial contact areas between the two metal oxides. This architectural arrangement gives rise to the creation of numerous energy barriers, effectively hindering electron migration. Despite exhibiting the acceptable response, TZ1 can be applied in electronic nose systems to effectively detect lung cancer indicators with low concentrations (i.e., acetone, formaldehyde, NH3) in light of its high stability and steady signal-to-noise ratio.

Synthesis and Characterization of TiO2-ZnO Nanocomposite Photocatalyst for the Removal of Basic Violet 14 as an Industrial Dye

Binary nanocomposites are one of the promising photocatalysts for the photodegradation of toxic industrial organic dyes which are used as dying agents in different industries including garments and textiles, leather, paint and varnish industries. For this study, TiO2-ZnO nanocomposites were fabricated by the hydrothermal process; where ZnSO4.7H2O is used as a precursor and TiO2 is used as a supporting material. The prepared TiO2-ZnO nanocomposites were calcined at three distinct temperatures 300 °C, 400 °C, and 500 °C. These composite materials were characterized by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), Energy Dispersive X-Ray (EDX), and Fourier Transform Infrared (FTIR) analyzes. Basic Violet 14 (BV14), an industrial dye, was modelled to examine the photocatalytic role of TiO2-ZnO under different experimental setups such as calcined temperatures, catalyst loading, concentrations of the BV14 dye, pH, and light sources. TiO2-ZnO prepared at 500 °C acted as the best photocatalyst among three nanocomposites and the prepared TiO2-ZnO worked better than solitary TiO2 and ZnO to decolorize the BV14 dye. In the presence of sunlight, UV light, and visible light the percentages of degradation of BV14 were found to be 81.78 %, 69.58 %, and 31.24 %, respectively. The maximum photodegradation corresponded to 0.175 g/100 mL of suspension of nanocomposite with an initial 3.0×10−5 M of BV14 having solution pH 6.88. The surface reaction constant and Langmuir-Hinshelwood adsorption constant were obtained to be 5.5×10−8 mol.L−1.min−1 and 1.7×108 L.mol−1, respectively.

Facile synthesis and enhanced acetone sensing properties of ZnO/TiO2 nanocomposite at room temperature

This paper reports a clear outline of the synthesis and gas-sensing characteristics of pure ZnO, TiO2 nanoparticles (NPs) and ZnO/TiO2 (ZT) nanocomposite (NC) for acetone detection at room temperature for diabetes screening. Thesamples were synthesized using an uncomplicated low-cost co-precipitation method. The ZT nanocomposites have shown a combined phase structure of ZnO (wurtzite) and TiO2 (anatase) from X-ray diffraction. The absorbance of the samples was analyzed by UV–Vis Spectrophotometer and a variation in the optical bandgap is studied.A high-performance ZT NC gas sensor is successfully realized for excellent selectivity, and quick response-recovery towards acetone detection. The sensing mechanism is ascribed to the composition, morphology, and enhanced oxygen adsorptionsites revealing better performances than the pure ZnO and TiO2 NPs. The ZT NC of composition ZnO (0.60 at.%):TiO2 (0.40 at.%) is observed to enhance the acetonegas detection signal for the lowest sub micro level ppb concentration of 100 ppb (parts per billion) in comparison to the pure ZnO and TiO2 nanoparticles. A superior response time (τres) of 13 s and recovery time (τrec) of 11 s are observed for ZT-1 sample with a high sensitivity response of 179 % is studied and therefore the nanocomposite material can be successfully utilized for acetone biomarker in diabetes.

Immobilization of ZnO-TiO2 Nanocomposite into Polyimidazolium Amphiphilic Chitosan Film, Targeting Improving Its Antimicrobial and Antibiofilm Applications.

This study presents a green protocol for the fabrication of a multifunctional smart nanobiocomposite (NBC) (ZnO-PIACSB-TiO2) for secure antimicrobial and antibiofilm applications. First, shrimp shells were upgraded to a polyimidazolium amphiphilic chitosan Schiff base (PIACSB) through a series of physicochemical processes. After that, the PIACSB was used as an encapsulating and coating agent to manufacture a hybrid NBC in situ by co-encapsulating ZnONPs and TiO2NPs. The physicochemical and visual characteristics of the new NBC were investigated by spectral, microscopic, electrical, and thermal methods. The antimicrobial indices revealed that the newly synthesized, PIACSB-coated TiO2-ZnO nanocomposite is an exciting antibiotic due to its amazing antimicrobial activity (MIC/MBC→0.34/0.68 μg/mL, 0.20/0.40 μg/mL, and 0.15/0.30 μg/mL working against S. aureus, E. coli, and P. aeruginosa, respectively) and antifungal capabilities. Additionally, ZnO-PIACSB-TiO2 is a potential fighter of bacterial biofilms, with the results being superior to those of the positive control (Cipro), which worked against S. aureus (only 8.7% ± 1.9 biofilm growth), E. coli (only 1.4% ± 1.1 biofilm growth), and P. aeruginosa (only 0.85% ± 1.3 biofilm growth). Meanwhile, the NBC exhibits excellent biocompatibility, as evidenced by its IC50 values against both L929 and HSF (135 and 143 µg/mL), which are significantly higher than those of the MIC doses (0.24-24.85 µg/mL) that work against all tested microbes, as well as the uncoated nanocomposite (IC50 = 19.36 ± 2.04 and 23.48 ± 1.56 µg/mL). These findings imply that the new PIACSB-coated nanocomposite film may offer promising multifunctional food packaging additives to address the customer demand for safe, eco-friendly food products with outstanding antimicrobial and antibiofilm capabilities.

Synthesis and Characterization of ZnO Doped TiO2 Nanocomposites for Their Potential Photocatalytic and Antimicrobial Applications

As a result of the sol-gel method, we were able to produce pure ZnO and ZnO-doped TiO2 nanocomposites. The hexagonal wurtzite phase in ZnO products was discovered by powder X-ray diffraction (XRD). ZnO products are typically hexagonal wurtzite crystallites, formed according to the Debye Scherrer formula. Nanocomposites with significant morphological changes were created using the sol-gel process, including those that resembled rocks. To determine the composition of Zn, O, and Ti atoms in the samples, a multidimensional X-ray analysis was performed. There is an energy gap between 3.61 eV, as determined by UV-vis spectroscopy. In this study, pure ZnO and ZnO-doped TiO2 nanocomposites were used to study the degradation of methylene blue (MB) under visible light irradiation. Over an irradiation course of 6 h, a ZnO-doped TiO2 composite (84%) were studied. As determined by the kinetic analysis, nanocomposites made from pure ZnO and ZnO-doped TiO2 followed pseudo-first-order kinetics. In the presence of ZnO-doped TiO2 nanocomposites, antibacterial activity was significantly improved. This was shown to be effective against Gram-positive and Gram-negative bacteria (Escherichia coli and B. sublittus). There is evidence that the metal oxide nanocomposites that are produced can be used as an appropriate antimicrobial and disinfection alternative, particularly in biomedical settings, as reported in more detail.

Synthesis of Semiconductor Nanosized Composite Photocatalyst

Every day, composites become an important part of modern functional materials not only due to their complex structure, but also unique new properties. Nanoarchitectonics is a new field that concerns the design and transformation of nanostructures into functional materials at the nanoscale level [1-3]. A composite material is a combination of two or more materials that provides better properties than its individual components [4-5].This paper presents the results of the synthesis of the TiO2-ZnO nanocomposite, as well as the experimental results of the study of some of its properties. The method of precipitation using a reducing agent with intermediate precipitation of zinc hydroxides on the surface of industrial titanium (IV) oxide and their subsequent heat treatment was used for the synthesis of TiO2-ZnO (1:3).The obtained SEM image is presented in Fig and shows that the particles of the synthesized TiO2-ZnO composite have the shape of flakes, which are easily agglomerated into aggregates of complex shapes and different sizes. The electronic image also shows that the individual separated particles have the size which is less than 0.1μm (100 nm), i.e. are in the nanometer range.In order to determine the optical band gap, the obtained TiO2-ZnO nanocomposite powder was dispersed in distilled water by ultrasound to form a suspension, for which the absorption spectrum was then taken. The obtained data were calculated using the Kubelkа-Munch formula and constructed the dependence. Іt can be stated from the data presented that the optical band gap of the obtained powder is ~2.4 eV.

Tuning Photophysical Properties of ZnO/TiO2 Nanocomposite Thin Films by Controlling Anatase Titania Content

The influence of the anatase titania nanoparticles (TiO2 NPs) content on the structural and optical properties of ZnO/TiO2 nanocomposites (ZTNCs) was demonstrated. The solution blending method was employed to prepare the ZTNCs with various ratios prior to their deposition onto glass substrates to form thin films. The X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), and transmission electron microscope (TEM) techniques revealed that the crystallite size, grain size, and particle size of each TiO2 and ZnO NPs are almost equal. In addition to these techniques, Fourier transform infrared spectroscopy (FTIR) evidenced the homogeneity distribution of the TiO2 within the ZnO NPs. The structural properties of the wurtzite ZnO NPs such as crystallite size, lattice strain, dislocation density, bond length (L) of Zn–O, energy density (u), lattice stress (L S), Young’s modulus, and unit cell volume (V), can be tuned by incorporation of anatase TiO2 NPs in various content. Moreover, the optical properties of the wurtzite ZnO NPs such as absorbance, optical energy band gap (E g), energy gap tail (E u), steepness parameter (σ), and emission intensity can be tuned by incorporation of anatase TiO2 NPs in various contents. The E g and σ of ZnO NPs were decreased to reach at 2.41 eV and 0.0051, respectively, whereas the E u was increased to 4.598 eV upon the increment content of TiO2 NPs.

Fabrication of bacterial cellulose with TiO2-ZnO nanocomposites as a multifunctional membrane for water remediation

Superhydrophilic/underwater superoleophobic (SUS) membrane technology has attracted extensive attention for water purification. However, the fabrication of multifunctional membranes to satisfy the complex wastewater treatment is still a big challenge. In this work, bacterial cellulose (BC) based multifunctional SUS membranes were designed for water purification. Membranes were prepared by blending BC nanofibers with TiO2 nanoparticles (NPs), and further modified by the in situ growth of ZnO-NPs. The composite membranes showed oil/water (o/w) separation under a small driving pressure (0.2–0.3 bar) with a flux rate of 8232.81 ± 212 L m−2h−1 and with a high separation efficiency (>99.9%). Membranes could also separate oil-in-water emulsion with a separation flux of 1498 ± 74 L m−2h−1 and with high efficiency (99.25%). Moreover, the composite membrane exhibited photocatalytic activity under visible light with a high efficiency (>92%). The composite membranes were also investigated for antibacterial activity against Gram-positive and Gram-negative bacterial strains. This work may inspire the fabrication of next-generation multifunctional membranes for wastewater treatment, particularly oily wastewater, dyes and microbial contaminated water.

Structural and Optical Properties of ZnO-TiO<sub>2 </sub>Nanocomposite Synthesized with Various Molar Ratios by Hydrothermal Technique

Zinc oxide-titanium dioxide (ZnO-TiO2) have been successfully synthesized by hydrothermal method. ZnO-TiO2 nanocomposite were prepared at different molar ratio 100:0, 100:0, 30:70, 50:50 and 70:30. The objective of this research is to determine the effect of molar ratios on the structural and optical properties of ZnO-TiO2 nanocomposite. The samples were analyzed using X-ray diffraction (XRD) analysis, Field-emission scanning electron microscopy (FESEM) and UV-Vis spectroscopy. Based on the XRD results, it is revealed that ZnO-TiO2 nanocomposite consists of hexagonal wurtzite structure of ZnO and mixed of anatase/ rutile phase of TiO2. FESEM images showed ZnO in rod-like structure while TiO2 is formed in nanoparticle. ZnO-TiO2 composite is formed combination of rod-like and nanoparticles. UV-Vis spectra showed that all samples exhibited good absorption towards UV region. The calculated energy band gaps of ZnO-TiO2 composite are 2.92 eV which is slightly smaller compared to bulk ZnO and TiO2. The tuning energy band gaps of ZnO-TiO2 composite samples is a good indicator for use in catalytic activities.

Sunlight-active phytol-ZnO@TiO2 nanocomposite for photocatalytic water remediation and bacterial-fouling control in aquaculture: A comprehensive study on safety-level assessment

With a growing consciousness of the importance of nature stewardship, researchers are focusing their efforts on utilizing renewable energy, particularly solar energy, to address environmental concerns. In this context, photocatalysis has long been viewed as one of the most promising cleaning methods. Hence, we have prepared a sunlight-active phytol-assisted ZnO-TiO2 nanocomposite (PZTN) for photocatalytic bacterial deactivation and dye degradation process. The PZTN-photocatalysis effectively deactivated the bacterial pathogens as well as malachite green dye within 240 min under direct-sunlight. Moreover, this will be the first complete study on safety level assessment of photocatalytically-remediated water through toxicity studies. The obtained results evidenced that photocatalytically-deactivated bacteria and MG-dye showed to have no toxic effects, signifying that the PZTN-photocatalyzed water seems to be extremely safe for the environment. As a result of this research, we suggest that the PZTN could be a promising sunlight-active photocatalyst for environmental water treatment. On the other hand, biofouling is a ubiquitous phenomenon in the marine environment. Bacteria are the first organisms to foul surfaces and produce biofilms on man-made submerged materials. Interestingly, PZTN-coated PVC plastic-films effectively disallowed biofilms on their surface. This part of this research suggests that PZTN coated PVC-plastics are the best alternative for biofouling management.

Enhanced heterogeneous photocatalytic perozone degradation of amoxicillin by ZnO modified TiO2 nanocomposites under visible light irradiation

This study investigated enhanced photocatalytic activities of ZnO–TiO2 nanocomposite for ozonation and perozone degradation of amoxicillin (AMX) from water. A simple ball milling method was successfully developed for fabrication of ZnO–TiO2. The experiments were conducted in semi-batch mode to study effect of various operational parameters onto AMX degradation by ozonation and perozone under visible light irradiation, including composite ratio, solution pH, photocatalyst dosage, H2O2, and initial AMX concentration. Besides, the AMX degradation kinetic also was fully investigated. Especially, AMX degradation mechanism was deeply discussed using scavenger test of hydroxyl radicals and characteristic data of photocatalyst. The results indicate that optimal composite ratio between ZnO nanoparticles (NPs) and TiO2 was 10. The 10%ZnO–TiO2 catalyst was proved effectively enhancement of AMX degradation due to its highly inhibition ability towards recombination of photogenerated electron-hole pairs and enriched surface hydroxyl groups. The AMX mineralization efficiency by O3/H2O2/10%ZnO–TiO2/Vis maximized (80.0%) which was higher than the sum of those in individual photocatalysis and perozone systems (69.5%). This was due to a synergistic effect between photocatalysis and perozone causing by ZnO–TiO2. The enhanced mechanism of AMX degradation was due to interfacial reactions between O3 or hydroxyl radicals with adsorbed AMX on the ZnO–TiO2's surface, which were caused by photoexcited electrons stored on ZnO–TiO2 and transferred by O3 to produce H2O2, *OH, h +VB, *O2−, and *O3−. The reusability experiment verified a high stability of ZnO–TiO2 through four consecutive cycles with a negligible change in AMX removal. These findings show that ZnO–TiO2 was the fully promising photocatalyst for advanced oxidation processes (AOPs) to remove the antibiotic residue from wastewater.

Environmentally Benign Organic Dye Conversion under UV Light through TiO2-ZnO Nanocomposite

In this work, we developed a very simple and novel approach for synthesizing TiO2-ZnO nanocomposites via the urea-assisted thermal decomposition of titanium oxysulphate and zinc acetate at different weight ratios. The synthesized nanocomposite samples were studied by means of HR-TEM, XRD, STEM, UV–Vis DRS, PL and EDS. The observed results demonstrate that the TiO2-ZnO nanocomposite consists of an anatase crystal phase of TiO2 with a crystallite size of 10–15 nm. Combined characterization, including UV–Vis DRS, STEM, EDS and HR-TEM, revealed the successful formation of a heterojunction between TiO2 and ZnO and an improvement in UV spectrum absorption. The photocatalytic activity was explored using MO degradation under ultraviolet light illumination. The results of the optimized TiO2-ZnO nanocomposite show excellent photocatalytic activity and photostability over a number of degradation reaction cycles. In addition, the current approach has immense potential to be used as a proficient method for synthesizing mixed metal oxide nanocomposites.
