AB  - Nanocomposite powder ZrO2/Fe3O4 was synthesized in several steps. Firstly, magnetite nanoparticles with a protective layer of SiO2 were synthesized. Silica layer protects magnetite core and prevents the transfer of electrons from the conduction band of ZrO2 to magnetite during illumination. Secondly, a layer of ZrO2 was added to the nanoparticles by the solvothermal method. The resulting powder was purified with the help of a strong magnet that ensures complete separation of the magnetic material from the solution. The magnetic material thus synthesized was used as a photocatalyst in the decomposition reactions of 2,4 dichloro- and 2,4,6 trichloro- phenols in aqueous solutions with Simulated Solar light as an irradiation source. The results showed that nanocomposite is an effective adsorber and photocatalyst for selected compounds. Chlorophenols were chosen as a model of compounds in this study because they are often found in natural waters, which come from pesticides used in agriculture. Their toxicity is mostly reflected in the impact on the nervous system of animals and humans.

AB  - Urea-based graphitic carbon nitride (g-C3N4) is thermally exfoliated at 500 °C in the air
atmosphere, and nano-carbon nitride (n-C3N4) is obtained. While optical properties are assessed
using UV/Vis DR spectroscopy, structural and morphological parameters of two materials are
obtained using XRD, TEM, and FTIR. Flat-band potentials were determined from Mott-Schottky
plots, and combined with corresponding band-gap energies, to estimate conduction and valence
band potentials of both materials. Photocatalytic efficacy of both semiconductors in photocatalytic
degradation of three textile dyes under simulated solar light irradiation is compared, with the
conclusion that n-C3N4 expressed higher photocatalytic ability in the studied systems. Finally, in
order to provide reusability of the semiconductors in multiple consecutive photocatalytic cycles,
both photocatalysts were drop-coated on the jute-based post industrial waste. Reusability of juten-C3N4 material is probed in three consecutive photocatalytic cycles, and the obtained results
showed that this material can have a future in solving real-life environmental problems.

AB  - Two different synthetic routes were employed to modify surface of graphitic carbon nitride (g- CN) with copper nanoparticles (CuNPs). Structure, morphology and CuNPs distribution on presynthesized g-CN surface are characterized by FT-IR, XRD and TEM. Results suggested that the simpler method based on mixing of precursors in inert atmosphere and room temperature, resulted in better CuNPs distribution compared to method which used refluxing as a step in synthesis.

AB  - Hexagonal ZnIn2S4 is synthesized by simple and low-cost hydrothermal route. TEM images revealed formation of nanosheets. The estimated band-gap energy of synthesized sample is in the visible spectral region and has a value of about 2.25 eV. Photocatalytic properties of synthesized sample are probed in photocatalytic degradation of three selected dyes different in nature and structure, Rhodamine B (RhB), Methylene blue (MB) and Methyl orange (MO), under the illumination with simulated Solar light. Obtained results revealed that photocatalytic degradation of RhB and MO is mainly result of synergic effect of photogenerated holes and oxygen, while primary effect in ZnIn2S4/MB system is bleaching of the dye, but no photodegradation was observed. © 2019 Elsevier B.V.

AB  - Pure and a series of Fe3+ doped zirconia nanopowders were synthesized combining colloidal chemistry and solvothermal method from organometallic precursors in order to correlate doping and properties of zirconia matrix. After annealing of washed nanopowders at 600 °C, detailed characterization was performed using X-ray diffraction, UV/Vis absorption and luminescence, infrared and electron paramagnetic spectroscopy, transmission electron microscopy and BET measurements. Zirconia samples had mixed monoclinic and tetragonal crystalline phase; increasing Fe3+ ions concentration was followed by increasing of tetragonal phase share. In the sample with highest Fe3+ concentration, hematite can be detected. Also, UV/Vis spectrophotometry showed that Fe3+ doping lowers effective band gap of zirconia matrix from 4.5 eV (bulk value) to 2.1 eV for doped/nanocomposite samples. EPR measurements proved presence of dopant and showed that isolated Fe3+ ions in zirconia matrix exist in both crystalline phases; monoclinic and tetragonal (g 4.8 and g 4.27–4.2, respectively) surroundings. Zirconia samples were also successfully used as photocatalysts for photocatalytic degradation of 2, 4, 6, trichlorophenol. © 2019 Elsevier Ltd and Techna Group S.r.l.

AB  - Advanced oxidation processes (AOPs) as processes that utilize hydroxyl radicals (OH• ) for oxidation of diverse organic pollutants have received considerable attention in last decades, especially in wastewater treatment. Photocatalysis (as AOP) initiated by Solar light, as free and most abundant light source, is considered as easiest way to produce OH•  radicals. However, designing suitable photocatalyst that can be easily activated by Solar light, keeping it highly effective in degradation in wide spectra of organic pollutants, is still a challenge. Zirconia (ZrO2) is well-known transparent ceramic material commonly used as a catalyst and catalyst support, sorbent and oxygen sensor. Due to its wide band-gap (~ 5.0 eV) it needs UV light (less than 5% of Solar light) to be activated, so it’s not an obvious choice for photocatalyst. However, once activated, with conduction band potential placed at -1.0V (vs.NHE) and valence band potential placed at +4.0V(vs.NHE), it has ability to produce not only OH•  but also superoxide (O2 •¯ ) radicals. In order to exploit its “pros” and overcome its “cons”, we developed series of zirconia based materials and tested theirphotocatalyticefficacy in degradation processes of various model compounds.

AB  - Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM techniques were used for structural and morphological characterization of obtained samples. XPS spectra of mixed oxide samples were compared in order to correlate composition of samples with surface properties and presence of defects. Relative positions of defect states within band-gaps of semiconductors were estimated from UCPL spectra. UV-Vis DRS spectra revealed that both pure oxides experienced red shift of absorption thresholds compared to reference data. Photocatalytic activities of all samples were probed under simulated Solar light on three model compounds: phenol, 4-chlorophenol (4-CP) and 2, 4, 6-trichlorphenol (TCP). Pure TiO2 showed the highest photocatalytic activity in the case of phenol. However, pure ZrO2 and binary oxides showed higher photoactivity in degradation of 4-CP and TCP. The activity of wide band-gap semiconductors under simulated Solar light in photodegradation of phenol and its derivatives is most probably the consequence of formation of charge transfer complexes between pollutant molecules and semiconductors surface.

AB  - A serie of novel ZrO2/Polyaniline (PANI) hybrid nanocomposite powders were successfully synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate (APS) in water, in the presence of ZrO2 nanoparticles. Syntheses were performed at initial ZrO2/aniline mole ratios 50,100 and 150 to produce ZP-50, ZP-100 and ZP-150. The morphological, structural, and optical properties of the synthesized nano composites were studied using Transmission electron microscopy (TEM), X-ray powder diffraction (XRD), Raman, UV-Vis and Electron-paramagnetic resonance (EPR) spectroscopies. EPR spectra of ZP-50 and ZP-100 nanocomposites showed the presence of intensive peak at the g-values comparable to that for free electrons (2.0023) indicating the presence of oligo/poly (semiquinone radical cations), i.e. polarons as charge carriers in PANI part; ZP-150 showed weak polaron peak of PANI, and peak that can be assigned to defects in zirconia matrix (Zr3+, oxygen vacancies). The monoclinic crystal structure of ZrO2 nanoparticles in all nanocomposites was confirmed by XRD and by Raman spectroscopy. The photocatalytic activities of ZP nanocomposites were evaluated using the photocatalytic degradation of trichlorophenol (TCP) and Rhodamine B model compounds and compared with the activity of bare ZrO2 nanoparticles. Enhanced degradation efficiencies of nanocomposites regarding TCP degradation were observed. (C) 2017 Elsevier B.V. All rights reserved.

AB  - Dextransucrase (DS), the extracellular enzyme is of immense industrial importance, due to ability to produce dextran and oligosaccharides (OS). Worldwide interest in OS has been increasing, since they have been accorded the prebiotic status. However, the industrial application of DS for OS synthesis is limited, due to low yield of enzyme production and its low catalytic activity. Hence, there is a great interest for development of new technologies that can provide improved performance of biocatalyst. Enzyme immobilization technology is considered to be a crucial step for cheaper and more efficient usage of DS. Entrapment is one of the widely investigated immobilization methods, where enzymes are enclosed or confined within the polymer matrix without altering their native structure, developing bioreactors for commercial applications. Different matrices such as polyacryl-amide gel, alginate beads and agar–agar have been used for the entrapment of different enzymes and among them agar–agar is a biocompatible, non-toxic and strong solidifying agent for immobilization of various enzymes. In this work, the entrapment of DS was initiated by different quantity (1:9, 1:4 and 1:1) of dialyzed enzyme into agar- agar solution. Agar solution was prepared in distilled water by vigorous shaking at 100°C, autoclaved and was allowed to cool to 40–45°C. Afterwards, enzyme was incorporated and mixed thoroughly. This mixture was immediately poured into a clean Petri plate and left to solidify at room temperature. Polymer films with and without immobilized DS were analyzed in terms of enzyme activity and reusability and mechanical properties (tensile strength, elongation at break and elastic modulus). In order to remove un-entrapped enzyme the films were washed with double deionized water and sodium acetate buffer (pH 5.4) three times prior to enzymatic assay. For quantitative analysis of samples for OS production a Dionex Ultimate 3000 HPLC system was used. Results showed that maximum immobilization yield (74.11%) was achieved by use of 2 % agar and (1:9) enzyme: agar ratio. HPLC analysis confirmed the similar trend of OS formation in immobilized samples compared to free enzyme. The lowest tested fraction of enzyme immobilized into polymer matrix (1:9) improved tensile strength of films in comparison with control film, whereas higher concentration of enzyme led to decrease in mechanical resistance of films. Scanning electron microscopy of agar films before and after DS entrapment revealed significant morphological change on the matrix surface. Considering the economic feasibility, the entrapped DS indicated imperative recycling efficiency up to six reaction cycles. The results of this study revealed that an easily available and inexpensive matrix could be successfully employed for DS immobilization and OS production.

AB  - In this study, the nanocomposites based on semiconductor lead sulfide (PbS) nanoparticles and poly (vinyl alcohol) (PVA) were investigated. The gamma irradiation induced in situ incorporation of PbS nanoparticles in crosslinked polymer network i.e. PVA hydrogel was performed. PVA hydrogel was previously obtained also under the influence of gamma irradiation. UV Vis absorption and X-ray diffraction measurements were employed to investigate optical and structural properties of PbS nano particles, respectively, and obtained results indicates the presence of nanoparticles with approximately 6 nm in diameter and face centered cubic rock-salt crystal structure. The porous morphology was confirmed by scanning electron microscopy. Swelling data revealed that investigated hydrogels (PVA and PbS-PVA nanocomposite) shows non-Fickian diffusion, indicating that both diffusion and polymer relaxation processes controlled the fluid transport. The values of diffusion coefficients have an order of magnitude 10(-9) cm(2)/s (typical values for water diffusion in polymers) and the best fit with the experimental results showed the Etters approximation. Comparing the thermal properties of PbS-PVA xerogel nanocomposite with PVA xerogel it was observed that incorporation of PbS nanoparticles in crosslinked PVA matrix just slightly enhanced the thermal stability of nanocomposite.

AB  - Hot-injection method for synthesis of ZnIn2S4 (ZIS) in organic media was studied. Nanosized ZnIn2S4 is successfully synthesized in oleic acid/oleylamine mixture in different ratios, which are both: complexing and/or capping agents. Nanosheets/nanoscrolls of about 50 nm are obtained. The band gaps of synthesized nanostructures were calculated to be in the range from 2.6 to 3.0 eV, values which are increased compared to bulk value (2.3-2.5 eV). The increase of band gap can be assigned to nanodimensions of the particles. Potential of band edges is calculated using empirical equation and find to be in the range from -0.16 to -0.36 V for conduction band, and from 2.24 to 2.69 V for valence band. By using XRD and TEM techniques, crystal structure and morphology of obtained materials were investigated, and detailed formation and growth mechanism of nanosheets/nanoscroles is proposed accordingly.

The properties of the synthesized titania based materials were obtained using XRD, UV/vis and EPR spectroscopy and BET measurements. The doping of TiO2 induced a shift in the absorption threshold towards the visible spectral range, compared to pure titania. The process of annealing induced an increase in crystallinity and particle sizes in the obtained materials. The photocatalytic activity, using simulated Solar light (Vitalux lamp), of our samples was checked by following the photodegradation reaction of Rhodamine B and trichlorophenole as model compounds.

AB  - We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporated Si4+ ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powders were annealed at 600 degrees C and characterized using structural (XRD), morphological (SEM and TEM) and optical techniques (UV/vis DR, FTIR and photoluminescence spectroscopy). Their textural properties (BET method) and photocatalytic activity toward degradation of model compounds (tricholophenol and Rhodamine B) using simmulated solar light were obtained. We showed that by using hydrothermal synthesis method pure monoclinic ZrO2 highly crystalline powder can be obtained. Incorporation of Si4+ ions induced stabilization of tetragonal crystalline phase at room temperature and decreasing of particle sizes. Incorporation of Si4+ ions in zirconia matrix also resulted in increase of specific area of nanopowders. FTIR measurements were used as proof for existence of Zr-O-Si bond. Effective band gap of zirconia powders was reduced from 5 (pure ZrO2) to 3.8 eV for samples with Si4+ ions. All zirconia powders showed significant photocatalytic activity regarding degradation of triclorophenol and no activity regarding RB (Rhodamine B dye). Photocatalytic activity of zirconia was increased by incorporation of Si ions in the host matrix. The source of this observation is discussed correlating all obtained properties of pure and Si-incorporated nanopowders. Optimization of synthesis parameters and composition of zirconia samples obviously can lead to their photocatalytic activity comparable to Degussa TiO2 powder, famous and commercial photocatalyst.

AB  - A hot-injection method for the synthesis of CdIn2S4 in three different compositions of organic media/solvents was studied. Nanosized CdIn2S4 is successfully synthesized in an oleic acid/oleylamine mixture of complexing/capping agents. The obtained mesocrystals of 20-30 nm in diameter are self-organized in marigold-like structures. The estimated band-gap of synthesized semiconductor is in the visible spectral region and has a value of about 2.1 eV. The potential of the band edges is calculated using an empirical equation. The as-prepared material was successfully transferred from organic to aqueous media by using 2-mercaptoethanol in a surface ligand exchange process. Using a similar synthetic procedure, ZnIn2S4 synthesis was performed. The obtained materials were characterized using UV/vis spectroscopy, XRD and TEM. Formation and growth mechanisms of the synthesized materials are proposed.

AB  - Samples of AgInS2 and CuInS2 nanoparticles were synthesized by hot-injection method at 270 degrees C using 1-dodecanethiol (DT) and elemental sulphur (S) as sulphide precursors, and oleylamine as reaction medium and surfactant. Composition, crystal structure, and particle size of obtained materials were tracked by XRD and TEM/HRTEM measurements. It was shown that, due to its dual role as sulphur source and surfactant, DT drastically slows formation of desired material. Samples obtained with DT even after 4 h of reaction have traces of intermediary compound (beta-In2S3), whereas in samples synthesized with elemental S these traces are less pronounced. The growth mechanism and influence of each reaction step are discussed in detail.

Samples obtained with DT even after 4 h of reaction have traces of intermediary compound (beta-In2S3), whereas in samples synthesized with elemental S these traces are less pronounced. The growth mechanism and influence of each reaction step are discussed in detail.",
