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. 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

AB  - Evironmetally safe mortars in which part of the cement binder was replaced by mineral
additives (i.e. zeolite, bentonite and fly ash) were designed. Fly ash, as fine powdery byproduct
of coal combustion, comprises heavy metals in its composition. Bentonite and zeolite are natural
adsorbents with ability to immobilize certain toxic elements and prevent their migration from the
mortar structure. In this study the ability of bentonite and zeolite to adsorb toxic cations present in fly ash leachate was investigated. Metallic cations were detected in quantities not higher than 52.6, 15.5, 52.4 and 22.7 mg/kg for Zn, Pb, Cu and Ni respectively. Adsorption kinetic was
monitored using 0.1 mol/dm3 solutions of each of investigated cations (Zn2+, Pb2+, Cu2+ and
Ni2+) as well as multicomponent solution of all these cations during predefined time intervals in
the range from 10-1440 minutes. Adsorption isotherms were obtained in concentration range for
each cation of single and multicomponent solution in the range from 0.10-0.30 mol/dm3. The obtained
results of this investigation indicate that bentonite and zeolite are efficient adsorbents and,
therefore, they can be applied in combination with fly ash in environmentally-safe construction

AB  - Pure and nickel-modified alumina powders with different porosity were synthesized and applied on the glassy carbon electrode by means of Nafion polymer. The data obtained from the nitrogen adsorption-desorption isotherm confirmed that the pore structures in these materials are complex and tend to be made up of interconnected networks of pores of different size and shape. The addition of Ni2+ ions caused the changes in the textural properties of the samples. The influence of porosity on the electrochemical behavior of modified electrodes in quasi-reversible process was tested by cyclic voltammetry. Numerical correlations between electrochemical responses of GCE modified with alumina samples and textural properties have been established.

AB  - Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/gamma-Al2O3 particles were conducted in batch stirred and packed-bed tubular reactors at 60 degrees C. The proposed three-parameter kinetic model describing the overall reaction with a variable mechanism was successfully applied to both batch and continuous reactions. The process optimization was done using the response surface methodology combined with a central composite design. The obtained optimal catalyst concentration, methanol-to-oil molar ratio and reaction time for the batch reaction were 0.55% (CaO to the oil), 9:1 and 5.22 h, respectively. In the continuous process, the catalyst was highly active stable and slightly leachable during 30 h. The deactivation of the catalyst was due to massive deposition of the organic molecules from the reaction mixture, which sheltered the catalytically active sites on the catalyst surface.

AB  - This study discusses the possibility of supercritical solvent impregnation of polypropylene and polyamide fabrics as well as cellulose acetate in the form of beads and films with pyrethrum extract in order to fabricate functionalized materials with repellent properties. Impregnation experiments were performed at temperature of 40 degrees C and pressures of 10 and 20 MPa in supercritical carbon dioxide. The time of impregnation was varied from 0.5 to 18 h. Loadings of pyrethrum extract into polypropylene fabrics and cellulose acetate films higher than 30% were attainable at 10 MPa. In the case of polyamide fabrics and cellulose acetate beads, the pressure of 20 MPa was needed for obtaining the loadings higher than 11%. Pyrethrum extract release study revealed different capabilities of the tested materials for the repellent release, implying a variety of their possible applications. The impregnated solids were characterized by SEM, DSC, FTIR, Mercury intrusion porosimetry analyses and HPLC analyses.

AB  - The electrooxidation of glucose on a polycrystalline gold electrode from alkaline and saline solutions was investigated. The influence of Nafion on the oxidation of glucose under the same conditions was also studied. The presence of Nafion on the surface of a polycrystalline gold electrode decreased the rate of glucose oxidation in alkaline solution. The sensitivity of glucose determination was diminished. However, processes occurring at the electrode were clearly separated. Stable cyclic voltammogram of a polycrystalline gold electrode was obtained in saline solution. The addition of glucose to saline solution initiated the reaction of gold dissolution. The presence of Nafion on the electrode surface prevented the formation of hydrous gold oxide. The addition of glucose to saline solution led to the passivation of the Nafion-covered gold electrode. The gold electrode pretreated in alkaline solution and covered with Nafion was used for glucose detection in saline solution. The linear behavior was obtained in the concentration range from 2 to 10 mM with the slope of 0.0015 mA/mM and the coefficient of 0.95. The chronoampermetric response of the pretreated gold electrode covered with Nafion was also tested.

abstract = "The electrooxidation of glucose on a polycrystalline gold electrode from alkaline and saline solutions was investigated. The influence of Nafion on the oxidation of glucose under the same conditions was also studied. The presence of Nafion on the surface of a polycrystalline gold electrode decreased the rate of glucose oxidation in alkaline solution. The sensitivity of glucose determination was diminished. However, processes occurring at the electrode were clearly separated. Stable cyclic voltammogram of a polycrystalline gold electrode was obtained in saline solution. The addition of glucose to saline solution initiated the reaction of gold dissolution. The presence of Nafion on the electrode surface prevented the formation of hydrous gold oxide. The addition of glucose to saline solution led to the passivation of the Nafion-covered gold electrode. The gold electrode pretreated in alkaline solution and covered with Nafion was used for glucose detection in saline solution. The linear behavior was obtained in the concentration range from 2 to 10 mM with the slope of 0.0015 mA/mM and the coefficient of 0.95. The chronoampermetric response of the pretreated gold electrode covered with Nafion was also tested.",

AB  - Glassy carbon electrode was modified with different synthesized hybrid clay-based materials and tested in alkaline solution with and without H2O2. The hybrid materials were obtained by immobilizing hemoglobin (Hb) on acid activated (AA) clay, or on AA clay modified with different sodium dodecyl sul-fate (SDS) loadings. The obtained materials were characterized using DR UV vis and ESR spectroscopy, elemental analysis, and SEM. The characterization confirmed higher degree of hemoglobin incorpora-tion in the presence of SDS. The presence of SDS on the surface of clay particles resulted in the partial oxidation/denaturation of hemoglobin and formation of hemichrome. Cyclic voltammetry was used for the investigation of the electrochemical behavior of immobilized hemoglobin in alkaline solution. Two cathodic peaks at -0.45 V and -0.70 V were recorded and ascribed to the reduction of heme Fe(III)/Fe(II), and formation of HbFe(I) - highly reduced form of hemoglobin respectively. The latter peak reflects hemoglobin denaturation. The presence of H2O2 in the alkaline solution increased current intensities corresponding to both peaks (-0.45 V and -0.7 V). Linear response of peak current intensity vs. H2O2 concentration was monitored for all investigated samples within different H2O2 concentration ranges. The AA-SDSI.0-Hb electrode exhibited the highest current response with linear regression equation in the following form: I(mu A)= 7.99 +1.056 x1f1202] (mM) (R=0.996). The limit of detection of 28 mu M was estimated using the 3 sigma method. Different modified electrodes exhibited different degrees of denaturation resistance. The obtained val-ues of Michaelis-Menten constant indicated that prolonged cycling in the presence of SDS increases protein denaturation.

AB  - In this study, electrode coating based on sodium dodecyl sulfate (SDS) bound to smectite clay was synthesized
and characterized. In order to enable SDS bonding to clay surface, the acid modification of clay was previously
performed at 90 ºC for 2 h. The acid modification changed surface charge of smectite into positive, thus enabling
electrostatic interaction with negative sulfate ions from SDS. The presence of SDS in SDS/acid modified smectite
(SDS/AMS) structure was confirmed by elemental analysis. SEM analysis revealed the morphology of the
obtained sample. Glassy carbon electrode (GCE) was modified with a suspension of the synthesized SDS/AMS
and Nafion® solution (GCE-SDS/AMS) and a uniform film was obtained [1]. The electrochemical behaviour of
nicotine was tested with modified GCE using cyclic voltammetry. It has been shown previously that the electrochemical
response of nicotine on carbon based electrodes can be improved by adding SDS into electrolyte solution
[2]. On the other hand, clays have the ability to preconcentrate analytes because of their porous structure and the
presence of potential active sites [3]. Acid activated clays can be modified with SDS [4]. Therefore, the aim of
this study was to investigate the influence of SDS bound to smectite on the electrochemical behaviour of nicotine.
Britton-Robinson (BR) (0.1 M) supporting electrolyte buffer solutions in the pH range from 2.0-10.0 was used for
preparing the supporting electrolyte of nicotine. The influence of the pH of the supporting electrolyte, scan rate
and accumulation time were investigated and discussed. The GCE-SDS/AMS exhibited similar electrochemical
behaviour in comparison with the bare GCE but with the differences in the intensity and position of peak corresponding
to nicotine oxidation. The intensity of the oxidation peak was lower on the GCE-SDS/AMS that on the
bare GCE. In contrast, the onset and peak potentials were significantly shifted towards less positive values on the
GCE-SDS/AMS comparing with the bare GCE. On the other hand, the nicotine peak intensity increased gradually
as the accumulation time increased. Therefore, selecting the appropriate accumulation time the sensitivity of the
GCE-SDS/AMS can be improved. The above results demonstrate the possibility of use the synthesized SDS/AMS
in the nicotine electrooxidation process.

AB  - In this study, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) was synthesized by suspension copolymerization, functionalized by ring-opening reaction of the pendant epoxy groups with diethylene triamine and used for immobilization of Pd(II) ions from chloride and nitrate solutions under batch experimental condition. The amino-functionalized sample and samples with immobilized Pd(II) ions were characterized by Fourier transform infrared spectroscopy (FTIR) analysis and scanning energy-dispersive X-ray spectroscopy (SEM-EDX). The electrochemical behavior of electrodes composed of synthesized samples was tested in 0.1 M H2SO4 by means of cyclic voltammetry (CV). The shape of recorded CV showed dependence on the type of Pd-salt used for Pd immobilization. The reaction of oxidation of 4-chlorophenol (4-CP) from 0.1 M H2SO4 at investigated samples was also studied. Electrooxidation of 4-CP resulted in passivation and formation of reversible hydroquinone/benzoquinone on both investigated electrodes, although hydroquinone/benzoquinone formation was more pronounced on Pd immobilized from nitrite solution.

AB  - Heterogeneous photocatalytic oxidation technologies, based on the free-radical reaction initiated by a light irradiation of photocatalyst surface, are promising methods for water and air purification, being one of overwhelming concerns in the scientific community regarding the challenges of exponential environmental pollution increase. Mixed oxides derived from ZnAI containing layered double hydroxides (LDH) without or with doping agents (Fe, Sn and Ti) have been recently implemented as efficient and environmental-friendly materials in the photodegradation process of organic compounds in aqueous media. Considering both, the progress in the synthesis of photoactive LDH and evident drawbacks of classical methods, the study is focused on the development of an innovative, simple and cost effective synthesis method of TiO2 containing ZnAI LDH based photocatalysts with improved overall photo-catalytic and antibacterial performances in water purification processes. In order to elucidate the relationship between the functional material properties developed in TiO2 impregnation process and photo induced catalytic and antibacterial activity, comprehensive studies encompassed structural (XRD), textural (low temperature nitrogen adsorption), electronic properties (diffuse reflectance spectroscopy) and morphology (SEM) of developed TiO2-ZnAl LDH based materials, as well as the XPS study of the most active photocatalysts, in correlation to photo-induced catalytic activity (Methylene Blue degradation) and antibacterial activity (Gram-negative E. coli and Gram-positive bacterium S. aureus as indicator strains). The results confirmed that innovative impregnation method using base solution enables favorable interactions among active phases promoting the synergetic effect and complex interactions between the TiO2 (3 mas%) and ZnAl mixed oxides, enhancing photocatalytic activity to the level almost equal to TiO2, simultaneously improving the overall antibacterial performance.

AB  - Loading CaO onto spherically-shaped gamma-Al2O3 support was applied for the preparation of a cost-effective and environmentally-friendly heterogeneous catalyst for biodiesel production. Physico-chemical, textural and morphological characterization was performed using optical emission spectroscopy (ICP OES), Hg-porosimetry, N-2 physisorption, scanning electron microscopy (FESEM), X-ray diffraction (XRPD), Fourier transform infrared spectroscopy (ATR FTIR) and Hammett indicators. The effects of catalyst preparation conditions (different precursor salts and calcination temperatures) on the catalyst activity, and the reaction conditions (methanol-to-oil molar ratio and catalyst loading) on the reaction rate and esters yield were studied. In addition, catalyst stability was investigated. The most active catalyst was derived from the nitrate precursor after calcination at 475 degrees C (inert atmosphere). Under mild reaction conditions (60 degrees C, 5 h, 900 rpm, methanol-to-oil molar ratio of 12:1 and catalyst loading (CaO wt% to the oil) of 0.5%), the equilibrium ester content of 94.3% was obtained in the methanolysis of sunflower oil in a batch reactor. The catalyst remained sufficiently active in two consecutive cycles without any pretreatment. Mechanical erosion caused by stirring and massive deposition of organic molecules from the reaction mixture caused the decrease of catalytic activity while CaO leaching was negligible.

AB  - The effect of the residence time (i.e. liquid flow rate through the reactor), methanol-to-oil molar ratio and reaction temperature on the fatty acid methyl esters (FAMEs) content at the output of a continuous packed bed tubular reactor was modeled by the response surface methodology (RSM) combined with the 3(3) full factorial design (FFD) with replication or the Box-Behnken design (BBD) with five center points. The methanolysis of sunflower oil was carried out at the residence time of 1.0, 1.5 and 2.0 h, the methanol-to-oil molar ratios of 6:1, 12:1 and 18:1 and the reaction temperature of 40, 50 and 60 degrees C under the atmospheric pressure. Based on the used experimental designs, the model equations containing only linear and two-factor interaction terms were developed for predicting the FAME content, which were validated through the use of the unseen data. Applying the analysis of variance (ANOVA), all three factors were shown to have a significant influence on the FAME content. Acceptable statistical predictability and accuracy resulted from both designs since the values of the coefficient of determination were close to unity while the values of the mean relative percentage deviation were relatively low ( LT +/- 10%). In addition, both designs predicted the maximum FAME content of above 99%, which agreed closely with the actual FAME content (98.8%). The same optimal reaction temperature (60 degrees C) and residence time (2.0 h) were determined by both designs while the BBD model suggested a slightly lower methanol-to oil molar ratio (12.2:1) than the 3(3) FFD model (12.8:1). Since the BBD realization involved three times smaller number of experimental runs, thus requiring lower costs, less labor and shorter time than the 33 FFD, it could be recommended for the optimization of biodiesel production processes.

AB  - The present paper is an overview of the recent progress in the development of various CaO-based catalysts suitable for biodiesel production. The mechanism, kinetics and optimization of transesterification reaction over these catalysts are first considered. Then, the practical application of CaO-based catalysts is discussed with a special stress on leaching and reusability of these catalysts. Also, various continuous reactor systems currently in use for biodiesel production are appraised. In addition to it, purification of crude biodiesel and the ecological aspects of using CaO-based catalysts are considered. Finally, the potentials of CaO-based catalysts for heterogeneous catalysis for biodiesel production are emphasized to assess the future perspectives of their use. This review might help in selecting suitable CaO-based catalysts and the optimum reaction conditions for biodiesel production.

AB  - A series of arylazo pyridone dyes was synthesized by changing the type of the substituent group in the diazo moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The structural and electronic properties of the investigated dyes was calculated at the M062X/6-31 + G(d,p) level of theory. The observed good linear correlations between atomic charges and Hammett sigma(p) constants provided a basis to discuss the transmission of electronic substituent effects through a dye framework. The reactivity of synthesized dyes was tested through their decolorization efficiency in TiO2 photocatalytic system (Degussa P-25). Quantitative structure activity relationship analysis revealed a strong correlation between reactivity of investigated dyes and Hammett substituent constants. The reaction was facilitated by electron-withdrawing groups, and retarded by electron-donating ones. Quantum mechanical calculations was used in order to describe the mechanism of the photocatalytic oxidation reactions of investigated dyes and interpret their reactivities within the framework of the Density Functional Theory (DFT). According to DFT based reactivity descriptors, i.e. Fukui functions and local softness, the active site moves from azo nitrogen atom linked to benzene ring to pyridone carbon atom linked to azo bond, going from dyes with electron-donating groups to dyes with electron-withdrawing groups.

AB  - A series of silica-supported nickel catalyst precursors was synthesized with different SiO2/Ni molar ratios. Reduction of Ni catalyst precursors with different SiO2/Ni molar ratios under a hydrogen atmosphere was investigated at different heating rates. Kinetic parameters were determined using Kissinger-Akahira-Sunose isoconversional and invariant kinetic parameter methods. It was found that for all molar ratios, the apparent activation energy (E-a) is practically constant in the conversion range of 0.20  LT = alpha  LT = 0.80. In the considered conversion range, following values of E-a were found: 134.5 kJ mol(-1) (SiO2/Ni = 0.20), 139.6 kJ mol(-1) (SiO2 /Ni = 0.80), and 128.3 kJ mol(-1) (SiO2/Ni = 1.15). It was established that the reduction of Ni catalyst precursors with different SiO2/Ni molar ratios is a complex process and can be described by the Sestak-Berggren autocatalytic model. It was found that the reaction is more Langmuir-Hinshelwood type, as hydrogen dissociates rapidly on surface nuclei and the dissociated hydrogen reacts with the Ni-O active system. It was concluded that the reduction process proceeds through bulk nucleation, which is a dominant mechanism, where three-dimensional growth of crystals with polyhedron-like morphology exists. It was found that the Ni/Si ratio decreases after the reduction process. This has been explained by low Ni and higher Si surface concentrations. It has been disclosed that Ni dispersion decreases.

AB  - In a heterogeneous base methanolysis of vegetable oils one of the most important characteristics of the catalysts are the basicity and the availability of basic centers. The impact of these factors on the catalytic activity was investigated in the reaction of sunflower oil methanolysis by CaO/γ-Al2O3 catalyst. The particle morphology of CaO-dispersed onto γ-Al2O3 surface was analyzed by field emission scanning electron microscopy (FESEM), while basicity and basic strength of prepared catalysts were determined using Hammett indicators method. The results showed a strong dependance of catalytic activity on its basicity. The catalyst with the highest basicity was the most active, and decreasing basicity reduces activity of the catalyst.

abstract = "In a heterogeneous base methanolysis of vegetable oils one of the most important characteristics of the catalysts are the basicity and the availability of basic centers. The impact of these factors on the catalytic activity was investigated in the reaction of sunflower oil methanolysis by CaO/γ-Al2O3 catalyst. The particle morphology of CaO-dispersed onto γ-Al2O3 surface was analyzed by field emission scanning electron microscopy (FESEM), while basicity and basic strength of prepared catalysts were determined using Hammett indicators method. The results showed a strong dependance of catalytic activity on its basicity. The catalyst with the highest basicity was the most active, and decreasing basicity reduces activity of the catalyst. In addition, it was shown that the catalyst activity depends on the favorable spatial distribution of basic sites, i.e. of their availability.",

AB  - Reducing gas atmosphere containing CO and H2 as processing gasses is commonly used in the
metal processing industry for heat treatment of special metals. For the production of reducing
atmosphere conventionally are employed nickel catalysts on various ceramic supports. Since
the process takes place at high temperature, thermal stability and textural properties of catalysts
are of particular interest. In this work magnesia supported nickel catalysts were synthesized.
The catalyst synthesis consisted of single or successive impregnations with nitrate precursor
salts of nickel and modifiers (Al, Ca and Mg), followed by thermal catalyst activation. Nickel:-
modifier molar ratio was 10:1.The solid to liquid mass ratio was 1:3. The concentration of Ni in
impregnation solution varied from 1.0 to 3.0 moldm-3. Mercury intrusion porosimetry was used
for textural characterization since the synthesized catalysts were predominantly macroporous.
The impregnation led to decrease of total pore volume, broadening and shifting of pore size distribution curve towards smaller pores. These changes were enhanced with the increase of initial
concentration of Ni solution and number of successive impregnations as well as the nature of
modifier. The Ni-catalyst modified with Al showed the best textural properties.

AB  - The simultaneous photocatalytic degradation of two dyes: methylene blue (MB), a cationic dye, and arylazo pyridone dye (SD), an anionic dye was investigated using sol-gel prepared TiO2 particles. The paper shows the main difference in degradation kinetics between single dye solution and binary dye solutions. The effects of competitive adsorption and the concentration of the dyes on degradation rate were analyzed. The preferential adsorption capacity of TiO2 toward MB was attributed to electrostatic interactions between the cationic dye and negatively charged TiO2 surface, while repulsion between the negatively charged surface of the catalyst and SD dye results in its lower adsorption capacity. The TiO2 surface charge and accordingly adsorption affinity of investigated dyes were found to be the main factors affecting degradation rate of the dyes. In the single dye system, the catalyst showed considerably higher degradation activity toward MB than to SD. In binary dye systems, the presence of SD did not affect the degradation of MB. On the other hand, the degradation efficiency of SD was found to be highly influenced by initial MB concentration and absorption ability of MB. In addition, higher MB concentration induces the production of a higher amount of reaction products, which also determine the SD degradation rate. Three kinetic regimes for the photodegradation of SD in binary mixtures were observed, used as a starting point to elucidate most influencing parameters for SD reaction kinetics.

AB  - In this paper smectite-chitosan bionanocomposite (SM-C) based on smectite (SM) from Crni Timok (Black Timok) basin, Serbia, was synthesized and characterized using chemical analysis, XRD and FTIR. The SM-C obtained was used for the modification of a glassy carbon electrode (GCE). The modified electrode (GCE/SM-C) was tested in the electrooxidation of phenol and different nitrophenols in acidic and alkaline solutions. Cyclic voltammograms (CV) obtained for GCE/SM-C, contrary to that obtained for the bare glassy carbon electrode, exhibited multiple oxidative peaks. The cathodic limit set to allow encompassing of nitro group reduction increased sensitivity for 4-nitrophenol detection. It also led to the appearance of additional peaks of 2-nitrophenol and decrease of the electrode passivation rate. The first-order derivative linear sweep voltammetry improved the sensitivity of the detection of different phenolic compounds from their mixed solution. The application of GCE/SM-C in alkaline environment led to increased current response while lowering the passivation rate. The quantitative determination of phenol and nitrophenols in a mixture, based on electrooxidation, had some disadvantages in both acidic and alkaline solution. Nevertheless, the concept of electrooxidation as a method for the detection and distinction of phenol and its nitro derivatives from water solution was proven.

AB  - A series of silica-supported nickel catalyst precursors was synthesized with different SiO2/Ni molar ratios. Reduction of Ni catalyst precursors with different SiO2/Ni molar ratios under a hydrogen atmosphere was investigated at different heating rates. Kinetic parameters were determined using Kissinger-Akahira-Sunose isoconversional and invariant kinetic parameter methods. It was found that for all molar ratios, the apparent activation energy (E-a) is practically constant in the conversion range of 0.20  LT = alpha  LT = 0.80. In the considered conversion range, following values of E-a were found: 134.5 kJ mol(-1) (SiO2/Ni = 0.20), 139.6 kJ mol(-1) (SiO2 /Ni = 0.80), and 128.3 kJ mol(-1) (SiO2/Ni = 1.15). It was established that the reduction of Ni catalyst precursors with different SiO2/Ni molar ratios is a complex process and can be described by the Sestak-Berggren autocatalytic model. It was found that the reaction is more Langmuir-Hinshelwood type, as hydrogen dissociates rapidly on surface nuclei and the dissociated hydrogen reacts with the Ni-O active system. It was concluded that the reduction process proceeds through bulk nucleation, which is a dominant mechanism, where three-dimensional growth of crystals with polyhedron-like morphology exists. It was found that the Ni/Si ratio decreases after the reduction process. This has been explained by low Ni and higher Si surface concentrations. It has been disclosed that Ni dispersion decreases.

AB  - A series of arylazo pyridone dyes was synthesized by changing the type of the substituent group in the diazo moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The structural and electronic properties of the investigated dyes was calculated at the M062X/6-31 + G(d,p) level of theory. The observed good linear correlations between atomic charges and Hammett sigma(p) constants provided a basis to discuss the transmission of electronic substituent effects through a dye framework. The reactivity of synthesized dyes was tested through their decolorization efficiency in TiO2 photocatalytic system (Degussa P-25). Quantitative structure activity relationship analysis revealed a strong correlation between reactivity of investigated dyes and Hammett substituent constants. The reaction was facilitated by electron-withdrawing groups, and retarded by electron-donating ones. Quantum mechanical calculations was used in order to describe the mechanism of the photocatalytic oxidation reactions of investigated dyes and interpret their reactivities within the framework of the Density Functional Theory (DFT). According to DFT based reactivity descriptors, i.e. Fukui functions and local softness, the active site moves from azo nitrogen atom linked to benzene ring to pyridone carbon atom linked to azo bond, going from dyes with electron-donating groups to dyes with electron-withdrawing groups.

The observed good linear correlations between atomic charges and Hammett sigma(p) constants provided a basis to discuss the transmission of electronic substituent effects through a dye framework. The reactivity of synthesized dyes was tested through their decolorization efficiency in TiO2 photocatalytic system (Degussa P-25). Quantitative structure activity relationship analysis revealed a strong correlation between reactivity of investigated dyes and Hammett substituent constants. The reaction was facilitated by electron-withdrawing groups, and retarded by electron-donating ones. Quantum mechanical calculations was used in order to describe the mechanism of the photocatalytic oxidation reactions of investigated dyes and interpret their reactivities within the framework of the Density Functional Theory (DFT). According to DFT based reactivity descriptors, i.e. Fukui functions and local softness, the active site moves from azo nitrogen atom linked to benzene ring to pyridone carbon atom linked to azo bond, going from dyes with electron-donating groups to dyes with electron-withdrawing groups.",

AB  - Bentonite from locality Mečji Do was acid treated, characterized and denoted as MDA. The obtained material was used to modify glassy carbon electrode (GCE). The GCE was covered either with a suspension of MDA and Nafion (perfluorinated resin solution), or with the same suspension mixed with Carbon Black Vulcan XC72, Cabot Corporation (CB). Thus the influence of the presence of CB on the electrochemical performance of the modified bentonite based electrodes  was examined. The electrochemical properties of the electrodes were tested by cyclic voltammetry in 0.1 M H2SO4 aqueous solution containing 10 mM of phenol, at the scanning rate of 10 mV/s in the potential range from -0.3 V to 1.1 V. The anodic oxidation of phenol led to the formation of insulating polymeric film on modified bentonite based electrode. As a consequence, rapid decrease of the current of phenol oxidation was observed. The composite electrode prepared with CB powder exhibited better performance than its counterpart without CB. Better performance was reflected in the stability of the electrodes regarding electrode fouling during the phenol electrooxidation process and better mechanical durability of the modified bentonite based electrodes.
