AB  - This study was carried out at the Danube River and its tributaries during the Joint Danube
Survey 4 (JDS4) expedition. Three freshwater benthic species were used to estimate the quantity
of microplastics (MPs): Corbicula spp., Limnodrilus hoffmeisteri (Claparede, 1862), and Polypedilum nubeculosum (Meigen, 1804). Following the kick and sweep technique, individuals were sampled using a hand net or dredge. In order to estimate the number of MP articles/individual particles/g wet body mass, the body mass and total length of all specimens were measured. Alkaline (Corbicula spp.and L. hoffmaisteri) and enzymatic (P. nubeculosum) protocols were performed for tissue degradation. All samples were filtered through glass microfiber filters (mesh size 0.5 μm). The particles were photographed, measured, and counted. A total of 1904, 169, and 204 MPs were isolated from Corbicula spp., L. hoffmaisteri, and P. nubeculosum, respectively. To confirm the chemical composition of isolated MPs, a subsample of 46 particles of the fragmented particles from 14 sampling sites was analysed via μ-ATR-FTIR spectroscopy analysis. The particles were characterised as polycarbonate (PC), polyethylene terephthalate (PET), polypropylene–polyethylene copolymer (PP-PE), nylon (polyamide-PA) and cellophane, with the domination of PET.

AB  - Photocatalytic processes have been recognized as promising and sustainable methods for pollutant degradation and energy conversion. Due to the simplicity of the process, capacity for using renewable and pollution-free solar energy, mild reaction conditions, reasonable reaction time, complete pollutant degradation, no harmful byproducts, and cost-effectiveness, photocatalytic degradation processes are more promising than conventional physical methods. Due to its favorable properties, TiO2 semiconductor has been used as an ideal candidate for photocatalytic reactions. However, large band gap, fast e-/h+ recombination, and low light harvesting efficiency are the main obstacles that restrict its practical application. Using  g-C3N4 semiconductor in combination with TiO2  is an excellent strategy to enhance the photocatalytic activity under visible light irradiation. In this study, g-C3N4/TiO2photocatalyst was successfully synthesized and used in single and simultaneous photodegradation of cationic Methylene Blue and anionic Orange G dyes. To examine the heterojunction between g-C3N4 and TiO2 and the mechanism of the transport pathway of photogenerated e-/h+, the photoluminescence spectra and radical scavenger study were applied. The present research offers a novel approach in reaction mechanism analysis for degradation of dye pollutants in single/mixed solutions and suggests a strategy for determination of heterojunction type in g-C3N4/TiO2 systems.

AB  - ZnFe photocatalysts have been increasingly
investigated for water remediation due to the high demands
in this field, such as activity, toxicity, cost, and stability. The
presented study was focused on the simple, safe, non-toxic,
and eco-friendly synthesis and characterization of ZnFe-mixed
metal oxides in correlation with their functional properties.
Photocatalytic performance of these materials was evaluated
by rhodamine B photodegradation under simulated
solar light irradiation. The synthesized mixed oxides contained
hexagonal wurtzite ZnO as the predominant phase,
whereas, after thermal treatment, the formation of the
spinel-structured ZnFe2O4 phase was observed. The photocatalysts
with the additional spinel phase and thermally
treated at 300°C and 500°C exhibited superior photocatalytic
activity probably due to the highest amount of the
ZnFe2O4 spinel phase, favourable mesoporous structure,
and an optimal energy band gap of ∼2.30 eV that initiated
higher light-harvesting efficiency. The rhodamine B photodegradation
followed zero-order kinetics, indicating complete
coverage of active sites by the pollutant substrate.
Additionally, photocatalysts showed the highest efficiency
at the natural pH (6.8), being in accordance with green
synthesis principles. Simple, green route assembling synthesis
method, high photodegradation efficiency, and good
reusability make these ZnFe-mixed oxides great candidates
for potential application in practical wastewater treatments.

AB  - The visible-light-active heterojunctions based on TiO2 were extensively investigated due to their wide range of energy and environment applications. In this study, g-C3N4/titanate heterojunction photocatalyst was successfully prepared by a simple one-step calcination route from melamine and hydrothermally prepared titanates. The photocatalyst was characterized by different physicochemical methods, e.g., X-ray diffraction (XRD), scanning electron microscopy (SEM), and N2 physisorption analysis. The photocatalytic efficiency of synthesized photocatalyst was evaluated by single and simultaneous degradation of methylene blue (MB) and orange G (OG) dyes under solar and visible light irradiation. The photocatalyst exhibited improved visible light activity due to the efficient separation of photogenerated charge carriers and enhanced visible light absorption. The degradation of MB was examined under different reaction conditions to assess the influence of initial MB concentration, catalyst loading, and pH on the degradation kinetics. Dye degradation study in the single and binary dye systems revealed that adsorption was limiting step that governs the pollutant degradation order. Radical trapping experiments were performed using different types of scavengers to highlight the difference in photochemical reactions and mechanism of MB and OG dye degradation under different light irradiation. Comparison of the reaction pathways under visible and solar light irradiation supported with determined bandgap edges and photoluminescence (PL) analysis suggested that the g-C3N4/titanate heterojunction belonged to the type II heterojunction.

AB  - In this work hydrogen production activity of a series of the nickel-loaded, nitrogen-doped titanate-based photocatalysts was tested by water splitting reaction in isopropanol-water mixture. The utilization of ammonium ions during catalyst synthesis and subsequent calcination led to successful formation of nitrogen-doped nanotubular titanates with lower sodium content, favored titanate-to-anatase transformation and enhanced textural, morphological and interface properties. The photocatalytic tests revealed that hydrogen production activity of nitrogen-doped titanates is ten times higher compared to nitrogen-free titanates. The presence of highly photoactive anatase phase, improved anatase crystallinity and lower amount of sodium ions are found to be decisive factors for increased hydrogen production activity. The optimal nickel loading was determined and the variation in photocatalytic activity with reduction temperature was explained. Stability tests gave quantitative analysis of the effects of reaction products accumulation and photocorrosion on the catalyst deactivation.

AB  - The attachment of squaric acid, a non-aromatic molecule, to the surface of TiO2 powder induced the optical absorption of the obtained hybrid material in the visible spectral range due to the interfacial charge transfer complex formation. The optical characterization of the hybrid is supported by the density functional theory calculations of the model cluster. The paramagnetic species generated upon excitation with ultraviolet or visible light, in both TiO2 powders, pristine and surface-modified, were identified conducting low-temperature solid-state and indirect electron paramagnetic resonance (EPR) spectroscopy experiments (spin trapping and spin scavenging). The solid-state EPR experiments indicated the promotion of electrons from the organic moiety to the titania conduction band under visible-light excitation of hybrid. Also, the spin scavenging experiments showed that the electrons generated in the hybrid upon the visible-light activation facilitate the reduction of the radical cations present in the dispersion, while these effects are not observed for pristine TiO2.

AB  - Waste-based CaO was synthesized from chicken eggshell, which calcined form (900 ºC, 5 ºC/min, 4 h) was hydrated (80 ºC, S:L=1:5, 24 h) and rehydrated/calcined (600 ºC, 5 ºC/min, 4 h). The obtained catalyst was characterized (Hg-porosimetry and TPD-CO2) and tested in biodiesel synthesis from off-grade sunflower oil by transesterification to analyse the influence of water addition on reaction intensification. Water content was varied in the range from 1 wt% to 9 wt% by weight of oil. It is shown that water addition positively affects the catalytic activity leading to a reduction in induction time and to faster achievement of the reaction equilibrium (fatty acid methyl esters content > 95%), which for a water content higher than 1 wt% is achieved in 90 min. On the other hand, the equilibrium for the reaction without water addition was achieved considerably later (after 150 min).

AB  - Platinum doped titanate catalysts were synthesized via alkaline hydrothermal method, followed by incipient wetness impregnation method and temperature programmed reduction (TPR). The effects of sacrificial agents on the photocatalytic activity of platinum doped titanate catalysts were studied in water splitting/alcohol photoreforming process under simulated solar light irradiation. Mechanism of photocatalytic reactions were elucidated by additional experiments performed using temperature-programmed desorption/mass spectrometry (TPD/MS). The applied alcohols (methanol, ethanol and 1-propanol) have shown enhanced hydrogen production rate in water splitting/photoreforming. Decreasing hydrogen production rate were observed in order methanol>ethanol>1-propanol (with achieved 11.6, 12.5, and 5.9 mmol g-1 h-1, respectively) due to the decrease in carbon atoms in alcohol carbon chain.

AB  - Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZMFA) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation process. The obtained ZMFA was used as catalyst support of calcium oxide as an active component derived from waste chicken eggshells (ES). The ZMFA supported calcium oxide catalyst (xCaO/ZMFA) was synthesized by means of the ultrasound-assisted method. The influence of different concentrations of dispersed calcium oxide (x = 5–20 wt%) over ZMFA and thermal treatment at different temperatures (450–600 °C) were studied. The structural and morphological characterization showed that the original cancrinite structure was preserved. The basicity and textural properties indicated the presence of strong active sites in a well-defined pore network suitable for the reactions of bulky organic compounds such as triacylglycerols (TAGs). The highest activity (96.5% of fatty acid methyl esters) in the methanolysis of sunflower oil was achieved with the 20CaO/ZMFA catalyst under reaction conditions: temperature of 60 °C, methanol/oil molar ratio of 12:1, catalyst concentration of 4 wt%, and reaction time of 2 h. It was found that the optimal calcination temperature of the catalyst precursor was 550 °C. At calcination temperatures above 550 °C, the melting of the glassy phase became more intense whereby the molten phase partially reacted with calcium oxide forming the catalytically inactive calcium silicate compounds (wollastonite, larnite, etc.). The rate constants of the two tested kinetic models were correlated with the concentrations of active calcium oxide. The MRPD of both models was low indicating their reliability.

AB  - Conversion of sunlight energy via photocatalytic water splitting and photo-reforming of renewable biomass organic derivates has been increasingly utilized for hydrogen production. Photocatalytic processes have been used due to their sustainability, environmental-safety, and effectiveness. Pt/Ndoped titanate photocatalysts were synthetized via alkaline hydrothermal treatment, followed by Na+/NH4+ion exchange, impregnation and gaseous reduction. The activities of the photocatalysts were tested for hydrogen production via photocatalytic reforming of glycerol under simulated solar irradiation. The improved hydrogen production from photo-reforming of glycerol was attributed to the anatase active phase and surface area which enhanced the adsorption of glycerol onto the surface of catalysts; metallic Pt suppress the electron/hole recombination by trapping the photo-generated electrons; reduced band gap by incorporation of N into lattice of TiO2.

AB  - The efficiency of titanate-nanotubes-based photocatalysts towards hydrogen production was studied in the presence of the sacrificial agent, 2-propanol. The highest hydrogen production rate (~120 lmol h 1 g 1 ) was observed over surface-modified titanate nanotubes by 5-amino salicylic acid decorated with nanometer-sized silver nanoparticles. The X-ray diffraction analysis, transmission electron microscopy, nitrogen adsorption–desorption isotherms, and diffuse reflection spectroscopy were applied to characterize the prepared photocatalytic materials. The better photocatalytic performance of inorganic–organic hybrid materials in comparison to the pristine titanate nanotubes is a consequence of their improved light-harvesting ability due to the formation of interfacial charge transfer (ICT) complex, as well as the presence of metallic silver nanoparticles that suppress the recombination of photo-generated charge carriers. The spin trapping EPR experiments under irradiation of prepared photocatalysts with either UV or visible light were used to monitor the appearance of hydroxyl radicals and superoxide radical anions. The generation of superoxide radical anions under visible light irradiation was detected for hybrid materials, but not for the pristine titanate nanotubes. These results are a consequence of enhanced promotion ofelectrons to the conduction band due to extended absorption in visible spectral range in hybrids and support the higher efficiency of hydrogen generation observed for surface-modified titanate nanotubes by 5-amino salicylic acid decorated with silver nanoparticles.

AB  - Understanding the degradation behavior of azo dyes in photocatalytic wastewater treatment is of fundamental and practical importance for their application in textile-processing and other coloration industries. In this study, quantum chemistry, as density functional theory, was used to elucidate different degradation pathways of azo pyridone dyes in a hydroxyl radical (HO•) initiated photocatalytic system. A series of substituted azo pyridone dyes were synthesized by changing the substituent group in the para position of the benzene moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The effect of dye molecular structure on the photocatalytic degradation reaction mechanism was analyzed and quantification of substituent effects on the thermodynamic and kinetics parameters was performed. Potential energy surface analysis revealed the most susceptible reaction site for the HO• attack. The calculated reaction barriers are found to be strongly affected by the nature of substituent group with a good correlation using Hammett σp constants and experimentally determined reaction rates. The stability of pre-reaction complexes and transition state complexes were analyzed applying the distortion-interaction model. The increased stability of the transition state complexes with the distancing from the substituent group has been established.

The calculated reaction barriers are found to be strongly affected by the nature of substituent group with a good correlation using Hammett σp constants and experimentally determined reaction rates. The stability of pre-reaction complexes and transition state complexes were analyzed applying the distortion-interaction model. The increased stability of the transition state complexes with the distancing from the substituent group has been established.",

AB  - Nickel-modified titanate/TiO2 catalysts were prepared by deposition of nickel ions onto hydrothermally prepared titanate supports, followed by hydrogen temperature-programmed reduction. Two different nickel precursors (hydroxide and carbonate) were used to tune reducibility and to vary the crystal phase structure of the final catalysts. The precursor reducibility and functional properties of the final catalysts were investigated systematically using various characterisation techniques. The results revealed a more facile reduction of the hydroxide precursor compared to its carbonate counterpart. Moreover, it was found that the formation of the anatase phase was favoured by the use of the hydroxide precipitation agent. The photocatalytic activity towards hydrogen production of the prepared catalysts was evaluated in the presence of 2-propanol under simulated solar light irradiation. A thorough study of the photocatalytic performance of the synthesised catalysts was conducted as a function of the precipitation agent used and the reduction temperature applied. The catalyst with dominant anatase crystal phase displayed the highest photocatalytic activity with a maximum H2 production rate of 1040 μmol h−1 g−1, this being more than four times higher than that of its carbonate counterpart. The catalysts with titanate structure showed similar activity, independent of the precipitation method used. The nanotubular structure was found to be the dominant factor in the stability of photocatalysts under long-run working conditions.

AB  - Surface modification of Al2O3 powders, prepared using reproducible sol-gel synthetic route with small colorless organic molecules, induces charge transfer complex formation and the appearance of absorption in the visible spectral region. Comprehensive microstructural characterization involving transmission electron microscopy, X-ray diffraction analysis, and nitrogen adsorption–desorption isotherms, revealed that γ-crystalline alumina powders consist of mesoporous particles in the size range from 0.1 to 0.3 μm, with specific surface area of 54.8 m2/g, and pore radius between 3 and 4 nm. The attachment of catecholate-type of ligands (catechol, caffeic acid, gallic acid, dopamine and 2,3-dihydroxy naphthalene), salicylate-type of ligands (salicylic acid and 5-amino salicylic acid), and ascorbic acid, to the surface such γ-Al2O3 particles leads to the formation of colored powders and activates their absorption in visible-light spectral region. To the best of our knowledge, similar transformation of an insulator (Al2O3), with the band gap energy of 8.7 eV, into a semiconductor-like hybrid material with tunable optical properties has not been reported in the literature before. The density functional theory (DFT) calculations with periodic boundary conditions were performed in order to estimate the energy gaps of various inorganic/organic hybrids. The calculated values compare well with the experimental data. The good agreement between the calculated and experimentally determined band gaps was found, thus demonstrating predictive ability of the theory when proper model is used.

salicylate-type ligands (salicylic acid and 5-aminosalicylic acid) as well as catecholate-type ligands (catechol,
3,4-dihydroxybenzoic acid, caffeic acid and 2,3-dihydroxy naphthalene), induces the appearance of absorption in
the visible spectral region due to the interfacial charge transfer (ICT) complex formation. Thorough characterization
involving transmission electron microscopy, XRD analysis, and nitrogen adsorption-desorption isotherms,
revealed that loosely agglomerated CeO2 particles of the size ranging from 2 to 4 nm have cubic fluorite structure
and specific surface area of 140 m2/g. The attachment of salicylate- and catecholate-type of ligands to the surface
of CeO2 powders leads to the formation of colored powders with tunable absorption in the visible spectral region.
The density functional theory calculations with properly design model systems were performed to estimate the

AB  - Use of broken honeycomb-like expanded perlite as support for magnesium modified nickel catalysts in process of partial hydrogenation of sunflower oil was studied. By the use of the precipitation-deposition method, two groups of precursors were synthesized: different Ni/SiO2 mole ratios with constant Mg/Ni mole ratio 0.1, and different Mg/Ni mole ratios with constant Ni/SiO2 mole ratio 0.25. Characterizations of precursors were done (scanning electron microscopy, diffuse reflectance UV–Vis, infrared spectroscopy, N2-physisorption, temperature programmed reduction (TPR) and He-pycnometry) to determine the material differences, considering the change in morphology, structure, texture and reducibility with overall Ni and Mg content. In addition, TPR and hydrogen chemisorption were performed in order to estimate the temperature reduction range of supported precursors and the dispersion degree of nickel in reduced precursors, respectively. The interaction between Ni2+ and perlite support was established. Different reducibility and dispersion were obtained as a function of Ni/SiO2 and Mg/Ni mole ratios. After the precursor’s reduction and paraffin oil impregnation, the obtained catalysts were tested in a sunflower oil hydrogenation reaction.

abstract = "Use of broken honeycomb-like expanded perlite as support for magnesium modified nickel catalysts in process of partial hydrogenation of sunflower oil was studied. By the use of the precipitation-deposition method, two groups of precursors were synthesized: different Ni/SiO2 mole ratios with constant Mg/Ni mole ratio 0.1, and different Mg/Ni mole ratios with constant Ni/SiO2 mole ratio 0.25. Characterizations of precursors were done (scanning electron microscopy, diffuse reflectance UV–Vis, infrared spectroscopy, N2-physisorption, temperature programmed reduction (TPR) and He-pycnometry) to determine the material differences, considering the change in morphology, structure, texture and reducibility with overall Ni and Mg content. In addition, TPR and hydrogen chemisorption were performed in order to estimate the temperature reduction range of supported precursors and the dispersion degree of nickel in reduced precursors, respectively. The interaction between Ni2+ and perlite support was established. Different reducibility and dispersion were obtained as a function of Ni/SiO2 and Mg/Ni mole ratios. After the precursor’s reduction and paraffin oil impregnation, the obtained catalysts were tested in a sunflower oil hydrogenation reaction. Catalyst activity was monitored through the decrease of the refractive index and hydrogen consumption that gave the insight that the influence on catalyst activity represents the accessibility of triacylglycerols and not always the hydrogen determined dispersion degree, Proučavana je moguća upotreba ekspantiranog perlita, oblika lomljenog pčelinjeg saća,

AB  - TiO2-CeO2 nanopowders were synthesised by a ball-milling process and then annealed at temperatures from 500 degrees to 800 degrees C. X-ray diffraction and diffuse reflectance spectra were used in combination with temperature programmed desorption to determine the structural and microstructural changes of nanopowders as a the function of annealing temperature. The results of the X-ray analysis showed that the weight fraction of the cerianite phase remained unchanged with a temperature rise of 600-700 degrees C, indicating that the phase changes occur only within TiO2. The TiO2-CeO2 nanopowder showed enhanced optical properties with a red shift after the thermal treatment. Photocatalytic studies revealed that the sample annealed at 600 degrees C showed higher photocatalytic activity than samples annealed at lower or higher temperatures in the degradation of the methyl orange. The activity test of all samples is in accordance with photoluminescence measurements, proportional to the concentrations of hydroxyl radicals at the photocatalyst surfaces.

AB  - This work is focused on preparation of poly(urethane-siloxane)/titanium-dioxide nanocomposites (PUSNs) with enhanced features. PUSNs were prepared by the in situ polymerization reaction using titanium-dioxide as a nano-filler in different amounts (1, 2, 3 and 5 wt.%) with respect to the poly(urethane-siloxane) (PUS) matrix. PUS copolymer was based on α,ω-dihy-droxy-ethoxypropyl-poly(dimethylsiloxane), 4,4’-methylenediphenyldiisocyanate and 1,4-bu-tanediole. In order to investigate the influence of TiO 2 content on the structure, UV resistance, thermal properties, hydrophobicity and morphology of the prepared PUSNs, FTIR spectroscopy, UV-Vis diffuse-reflectance spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), contact angle measurements, surface free energy (SFE) analysis, water absorption, scanning electron microscopy (SEM) and atomic force microscopy (AFM) were performed. The PUSNs showed excellent UV resistance, high hydrophobicity, low surface free energy and also higher thermal stability and rougher surface and cross-section relief structure as compared to the pure PUS copolymer. Based on the obtained results it can be concluded that prepared PUSNs could be potentially used as protective coatings. © 2019, Association of Chemists and Chemical Engineers of Serbia.

AB  - Ovaj rad je fokusiran na pripremu poli(uretan-siloksan)/titan-dioksid nanokompozita (PUSN) sa poboljšanim svojstvima. PUSN nanokompoziti su 
bili pripremani postupkom in situ polimerizacije koristeći titan-dioksid kao nanopunilac u različitim količinama (1, 2, 3 i 5 mas.%) u odnosu na poli(ure tan-siloksansku) (PUS) matricu. PUS kopolimer je bio na bazi α,ω-dihi droksi-etoksipropil-poli(dimetilsiloksana), 4,4’-metilendifenildiizocijanata i 
1,4-butandiola. Sa ciljem da se ispita uticaj sadržaja TiO2 na strukturu, UV otpornost, termička svojstva, hidrofobnost i morfologiju dobijenih PUSN 
nanokompozita, primenjene su sledeće tehnike: FTIR spektroskopija, UV-Vis difuzna-refleksna spektroskopija, diferencijalna skenirajuća kalorimetrija (DSC), termogravimetrijska analiza (TGA), merenje kontaktnih uglova, određivanje slobodne površinske energije (SFE), određivanje apsorpcije vode, skenirajuća elektronska mikroskopija (SEM) i mikroskopija atomskih sila (AFM). Dobijeni PUSN uzorci su pokazali izuzetnu otpornost na UV 
zračenje, visoku hidrofobnost, nisku slobodnu površinsku energiju i takođe poboljšanu termičku stabilnost i hrapaviju površinsku i unutrašnju reljefnu 
strukturu u odnosu na čist PUS kopolimer. Na osnovu dobijenih rezultata zaključeno je da se dobijeni PUSN nanokompoziti mogu potencijalno koristiti kao zaštitni premazi.

abstract = "This work is focused on preparation of poly(urethane-siloxane)/titanium-dioxide nanocomposites (PUSNs) with enhanced features. PUSNs were prepared by the in situ polymerization reaction using titanium-dioxide as a nano-filler in different amounts (1, 2, 3 and 5 wt.%) with respect to the poly(urethane-siloxane) (PUS) matrix. PUS copolymer was based on α,ω-dihy-droxy-ethoxypropyl-poly(dimethylsiloxane), 4,4’-methylenediphenyldiisocyanate and 1,4-bu-tanediole. In order to investigate the influence of TiO 2 content on the structure, UV resistance, thermal properties, hydrophobicity and morphology of the prepared PUSNs, FTIR spectroscopy, UV-Vis diffuse-reflectance spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), contact angle measurements, surface free energy (SFE) analysis, water absorption, scanning electron microscopy (SEM) and atomic force microscopy (AFM) were performed. The PUSNs showed excellent UV resistance, high hydrophobicity, low surface free energy and also higher thermal stability and rougher surface and cross-section relief structure as compared to the pure PUS copolymer. Based on the obtained results it can be concluded that prepared PUSNs could be potentially used as protective coatings. © 2019, Association of Chemists and Chemical Engineers of Serbia. All rights reserved., Ovaj rad je fokusiran na pripremu poli(uretan-siloksan)/titan-dioksid nanokompozita (PUSN) sa poboljšanim svojstvima. PUSN nanokompoziti su 
bili pripremani postupkom in situ polimerizacije koristeći titan-dioksid kao nanopunilac u različitim količinama (1, 2, 3 i 5 mas.%) u odnosu na poli(ure tan-siloksansku) (PUS) matricu. PUS kopolimer je bio na bazi α,ω-dihi droksi-etoksipropil-poli(dimetilsiloksana), 4,4’-metilendifenildiizocijanata i 
1,4-butandiola. Sa ciljem da se ispita uticaj sadržaja TiO2 na strukturu, UV otpornost, termička svojstva, hidrofobnost i morfologiju dobijenih PUSN 
nanokompozita, primenjene su sledeće tehnike: FTIR spektroskopija, UV-Vis difuzna-refleksna spektroskopija, diferencijalna skenirajuća kalorimetrija (DSC), termogravimetrijska analiza (TGA), merenje kontaktnih uglova, određivanje slobodne površinske energije (SFE), određivanje apsorpcije vode, skenirajuća elektronska mikroskopija (SEM) i mikroskopija atomskih sila (AFM). Dobijeni PUSN uzorci su pokazali izuzetnu otpornost na UV 
zračenje, visoku hidrofobnost, nisku slobodnu površinsku energiju i takođe poboljšanu termičku stabilnost i hrapaviju površinsku i unutrašnju reljefnu 
strukturu u odnosu na čist PUS kopolimer. Na osnovu dobijenih rezultata zaključeno je da se dobijeni PUSN nanokompoziti mogu potencijalno koristiti kao zaštitni premazi.",

AB  - This study will focus on investigation of photocatalytic hydrogen production activity over low cost Ni modified titanates, as alternatives for highly cost and low-abundance noble metal based catalysts. The catalysts with different nickel loading were synthesized by deposition of predetermined amount of nickel on hydrothermally prepared titanate support, followed by hydrogen temperature programmed reduction (TPR). The final catalysts were characterized using various methods, such as N2 physisorption, XRD, TPR. The study showed that adequate selection of synthesis parameters results in catalyst with improved textural, morphological and structural properties. The investigation on the effect of the nickel content on the photocatalytic hydrogen production allowed us to define the optimal metal content in the synthesized catalysts.
