AB  - Nanokompozitni prah ZrO2/Fe3O4 sintetisan je uspešno u nekoliko koraka. Prvo su sintetisane nanočestice magnetita sa zaštitnim slojem od SiO2 koji sprečava prenos elektrona iz provodne zone ZrO2 na magnetit prilikom ozračivanja. Potom je na nanočestice nanet sloj ZrO2 solvotermalnom metodom. Dobijeni prah je prečišćen uz pomoć permanentnog magneta koji obezbeđuje potpuno ukalanjanje magnetnog materijala iz rastvora. Ovako sintetisan magnetni materijal je upotrebljen kao fotokatalizator u reakcijama razgradnje 2,4 dihlorofenolai 2,4,6 trihlorofenola u vodenim rastvorima. Rezultati su pokazali da je nanokompozit efikasan adsorber i fotokatalizator za odabrana jedinjenja. Hlorofenoli su izabrani kao model jedinjenja u ovoj studiji zbog toga što se često nalaze u prirodnim vodama, u koje stižu iz pesticida koji se upotrebljavaju u poljoprivredi. Njihova toksičnost se najviše ogleda u uticaju na nervini sistem životinja i ljudi.
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.

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  - Alumina can be obtained in several different phases depending on the synthesis parameters. All these phases have different morphology, crystal structure, water content, and surface chemistry that determines their application as catalysts or support for the (electro)catalyst. In this paper, the influence of anion on the electrochemical properties of copper-modified alumina was investigated. Two types of alumina with different water content, 3 mol H2O/ mol Al2O3 (designated as T) and 0.6 mol H2O/ mol Al2O3 (designated as G), were used in this study. Copper-modified alumina samples were prepared by ion exchange with a solution of CuSO4, CuCl2, or Cu(NO3)2. The obtained samples were characterized by DR UV/Vis spectroscopy and cyclic voltammetry. The DR UV/Vis results showed a broad band in the range of 300 – 600 nm corresponding to the ligand-to-metal charge transition band. The results showed that copper-modified G alumina showed a higher current originating from copper after the ion exchange procedure, regardless of the anion used. The order of activity was SO4 2- > Cl-  NO3 - for G alumina and SO4 2-  Cl- >NO3 - for T alumina.

AB  - Hydrogels consisting of radiation-degraded chitosan, poly(vinyl alcohol), and Ag nano-filler, were prepared by γ-irradiation in two-stage and single-stage procedures to examine the role of the synthesis procedure in improving the antibacterial activity. The light scattering method showed that radiation-degradation of chitosan occurred both by breaking the glucoside bonds and by Maillard's reaction. Elemental analysis indicated a reduction in the degree of deacetylation after degradation. The product of Amadori rearrangement and pigmented product melanoidins were determined by 1H NMR, FTIR, UV–Vis, and fluorescence spectroscopy. Enhancement of in vitro antibacterial activity of nanocomposites against Staphylococcus aureus and Escherichia coli was achieved by a single-stage procedure which results in greater mobility of radiation-modified chitosan in the network. This allows the exploitation of its potential, which is reflected in the possibility of the complexing of ultrasmall molecular Ag clusters. These complexes have a considerably stronger antibacterial effect. Ag in molecular form was confirmed by XPS analysis.

AB  - Enhanced optical properties of TiO2 thin films can be achieved by doping or coating with metals. Metal-doped TiO2 can reduce electron-hole recombination and increase hydroxyl radical concentration on the surface of TiO2, resulting in increase of the photocatalytic activity. TiO2 and TiO2-Au thin films were obtained by DC magnetron sputtering of Ti target with Ar ions in O2 atmosphere. In the case of Au buffered TiO2 thin films, two different systems were deposited for comparison. Post deposition annealing at 400 °C was carried out in nitrogen atmosphere for 3 h. The structural and optical characteristics of the prepared films were investigated in detail by the combination of high-resolution microscopic and spectroscopic techniques. The photo-degradation rate was measured using Rhodamine B which simulated pollutant. Post deposition annealing resulted in diffusion of Au atoms through the layer as it was revealed by transmission electron microscopy and energy dispersive X-ray spectroscopy. The obtained TiO2 thin films were found to be amorphous after deposition and annealing at 400 °C leads to crystallization of anatase phase. Analysis of the binding energy in the corresponding X-ray photoelectron spectra has confirmed stoichiometry of TiO2 and that concentration of Au on the surface can be controlled by sputtering and annealing conditions, thus changing optical properties by influencing the surface plasmonic nature. All Au doped TiO2 thin films exhibited enhanced wettability and photo-degradation rates when compared to pristine titania films. © 2022 Elsevier B.V.

AB  - The subject of this study were electrochemical characteristics of transition metal oxide electrodes, consisting specifically of ZrO2 and TiO2, which have different crystallographic structure and lattice parameters. Metal oxides are a significant class of materials which have found vast applications in electrocatalysis. Composites of diverse semiconductors typically display much enhanced electronic conductivity and decreased charge transfer resistance. The goal of this study was to hopefully prepare and investigate electrodes with improved properties, through combination of heterostructures of chemically and structurally dissimilar and wide-bandgap semiconductors. Electroactive surface area was determined by employing cyclic voltammetry peak current method.

AB  - Coupled oxide ceramic materials possess attractive properties, such as high surface areas, tunable pore size and shapes, various crystal structures, and a multitude of compositions, which endow them with potential applications in various areas of science and technology. Among these, porous zirconia-based ceramic materials, which can be considered as semiconductors with high band gap energy of ~5eV, have been the subject of intense research because of the potential new extensive use in photocatalytical degradation of organic pollutants. In the scope of this study mesoporous coupled alumina/zirconia composites were synthesized via the sol-gel method, followed by heat treatment at 500°C, for 5h. The XRD pattern of composites has shown that the addition of zirconia disrupts the crystallinity of alumina. The composites with higher zirconia content are characterized by peaks of the tetragonal zirconia phase. On the basis of the calculated flat band potentials from Mott-Schottky plots and optical band gaps, the conduction and valence band potentials were estimated for the composite semiconductors. Photocatalytic activity of synthesized samples in the process of degradation of trichlorophenol was obtained and correlated with band potentials and optical properties.

AB  - One of the ways to increase efficiency of TiO2 thin films is by doping and coating with metals. Metaldoped TiO2 can reduce electron-hole recombination and increase hydroxyl radical concentration on the surface of TiO2, resulting in increase in the photocatalytic activity.Recent studies of J. Li at al.[1] and S. Y. Lee et al.[2] with Au doped TiO2 thin films showed that this systems have enhanced photocatalytic activity in comparison to pure TiO2 thin films. Also recent study[3] showed that Au doped TiO2 thin films are great candidates beside photocatalysis for enhancing visible light water splitting.TiO2 and TiO2:Au thin films were obtained by DC magnetron sputtering of Ti target with Ar ions in O2 atmosphere. In the case of doped TiO2 thin films with Au, three different systems were deposited for comparison (Fig.1). Post deposition annealing for 3h on 400 °C was carried out in nitrogen atmosphere. For structural analyses XRD, XPS, TEM and AFM methods were used, while for optical characterization UV/Vis method was used. The photo-degradation rate was measured using Rhodamine B which simulated pollutant. Analysis of the binding energy in the corresponding XPS spectra showed that deposited films have good stoichiometry of TiO2 and that concentration of Au on the surface can be controlled by sputtering and annealing conditions. Post deposition annealing caused diffusion of Au atoms through the layer as it was shown by TEM and EDS. Obtained TiO2 thin films before deposition were amorphous-like structured, and after annealing on 400 °C showed that anatase phase dominates in the structure. All Au doped TiO2 thin films showed better photo-degradation rates then pure TiO2.

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  - 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.

AB  - Nitrogen-doped TiO2 (N-TiO2) is considered as one of the most promising materials for various photocatalytic applications, while noble metals Pd and Pt are known as good catalysts for hydrogen evolution. This work focuses on the determination of structural and electronic modifications of N-TiO2, achieved by noble metal deposition at the surface, as a starting indicator for potential applications. We focus on the properties of easily synthesized nanocrystalline nitrogen-doped anatase TiO2, modified by depositing small amounts of Pd (0.05 wt%) and Pt (0.10 wt%), aiming to demonstrate efficient enhancement of optical properties. The chemical states of dopants are studied in detail, using X-ray photoemission spectroscopy, to address the potential of N-TiO2 to act as a support for metallic nanoparticles. DFT calculations are used to resolve substitutional from interstitial nitrogen doping of anatase TiO2, as well as to study the combined effect of nitrogen doping and oxygen vacancy formation. Based on the binding energies calculated using Slaters transition state theory, dominant contribution to the N 1s binding energy at 399.8 eV is ascribed to interstitially doped nitrogen in anatase TiO2. Given that both structure and photocatalytic properties depend greatly on the synthesis procedure, this work contributes further to establishing correlation between the structure and optical properties of the noble metal modified N-TiO2 system.

AB  - We report the successful, low temperature synthesis of pure and Fe-doped titania nanoparticle (NP) powders, using organic Ti- and Fe-precursors. 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  - ZnO spheroidal nanoparticles, synthesized by microwave processing, were used for preparation of composites with polyethylene oxide (PEO). The phase purity and crystal structure of the composites were investigated by X-ray diffraction (XRD) and Raman spectroscopy. The composites particles morphology and size distributions were studied by FE-SEM and laser diffraction particle size analyzer, respectively. The optical properties were studied using UV Vis diffuse reflectance and photoluminescence spectroscopy. It is found that in the wavelength range 550-800 nm, ZnO and ZnO/PEO composites absorb about 50% of the incident light intensity. Also red-shift of band gap energy (0.12-0.15 eV) compared to bulk ZnO was determined. The effect of PEO molecular weights, 200,000, 600,000 and 900,000 g/mol, on photocatalytic activity of ZnO/PEO composites were examined via de-colorization of methylene blue (MB) under direct sunlight irradiation. A large efficiency of MB de-colorization was found after 6 h of irradiation. The enhanced photocatalytic activity of ZnO/PEO composites is attributed to the: (1) lattice defects introduced in ZnO crystal structure by rapid microwave processing, and (2) presence of PEO as a source of oxygen interstitials. In order to confirm and further clarify the experimental results ab initio calculations based on density functional theory (DFT) were performed. (C) 2016 Elsevier Ltd. All rights reserved.

AB  - Titanium dioxide nanopowders, doped with different amount of Fe3+ ions (0.3-5.0 mass%), were synthesized by acid-catalyzed sol-gel method in a non-aqueous medium. The obtained powders were characterized by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectrometry (EDX) and UV/vis spectroscopy. Degradation reaction of crystal violet (CV) azo dye is used to test the photocatalytic activity of iron doped titanium dioxide nanopowders. The results are correlated with previous investigations about the structure and physico-chemical characteristics of obtained nanopowders. (C) 2015 Elsevier Ltd. All rights reserved.
