AB  - Cobalt-doped alumina catalyst was tested in peroxymonosulfate-induced degradation of two
textile dyes: anionic-Orange G (OG) and cationic-Basic Blue 41 (BB). Oxone®, mixed salt
containing peroxymonosulfate as an active component, was used as an oxidizing agent.
Catalytic tests were performed in a thermostated reactor equipped with a mechanical stirrer.
Dyes degradation was followed using a UV-Vis spectrophotometer. Characteristic peak
maximum in UV-Vis spectrum was identified at λ=478 nm for OG, and at λ=609 nm for BB.
Two OG concentrations were applied: 20 mg dm-3 and 50 mg dm-3. BB concentration was 20
mg dm-3 in all experiments. The reaction temperature was 30 ºC. Apart from simultaneous
dyes degradation, single-component solution degradation tests were also performed. Both
dyes were found to be degradable in single dyes systems, with OG showing a higher
degradation rate. When it comes to simultaneous degradation, it was noticed that the
degradation of the BB did not occur while OG was present in the system. This phenomenon
can probably be attributed to the difference in the molecular structure and charge of the
investigated dyes.

AB  - Catalytic oxidative degradation of a textile dye Orange G was investigated in the reaction
system where oxidant Oxone® was used as a source of SO4˙ˉ anion radicals. Cobalt-doped
alumina was tested as a heterogenous catalysts for Oxone® activation. The catalyst was
synthetized and calcined at 500 °C. The influence of different reaction parameters was
followed: the Oxone® dosage, Orange G concentration and initial pH of the reaction solution.
The Oxone® dosage was varied from 10 mg to 80 mg. Small differences in degradation
efficiency were observed but mass of 40 mg of Oxone® was found to be optimal in the first
hour of the reaction. The effect of the Orange G concentration was investigated in the range
from 20 mg dm-3 to 50mg dm-3. For the concentration of 20 mg dm-3 the reaction was much
faster than for other investigated concentrations. The effect of the pH was tested in the range
from 2 to 9. The optimal pH range was found to be between 6 and 9, but reaction was feasible
also for lower pH. It can be concluded that investigated catalyst is applicable with high
efficiency in the wide range of Oxone® dosages, dye concentrations and initial pH values.

AB  - A novel and simple electrochemical sensor for the determination of gallic acid is presented. The alumina sample was characterized by X-ray diffraction, FTIR, and particle size distribution analysis. The carbon paste electrode was modified with alumina and used as a sensor. The performances of the sensor were assessed by cyclic voltammetry and square-wave voltammetry techniques. The oxidation of gallic acid on alumina-modified carbon paste electrode was an irreversible diffusion-controlled process. The linear relationship of peak current and concentration was obtained for the concentration range of 1.4 to 115 µM with the limit of detection of 0.8 µM. The sensor’s ability to test gallic aid in real systems was successfully tested in wine samples.

AB  - The mesoporous zirconia/alumina composites were synthesized via a sol–gel method,
followed by heat treatment at 500 ◦C for 5 h. The effect of the ZrO2/Al2O3 ratio on the structural and
textural properties of the obtained composites was explored. Sorption analysis has confirmed that
all samples have a mesoporous structure whose parameters (SBET, Vp and Dmax) strongly depend
on the ZrO2/Al2O3 ratio. The XRD pattern of composites has shown that the addition of zirconia
disrupts the crystallinity of alumina. The composites with higher zirconia content (50% ZrO2 and
67% ZrO2
) are characterized by peaks related only to the zirconia phase. UV/Vis diffuse reflection
spectra of all samples revealed that composites have more intensive absorption compared to pure
oxides for wavelengths larger than 250 nm and similar band gaps. Photoluminescence measurements
showed presence of defects in all samples, which are responsible for photocatalytic activity. All
samples showed significant adsorption/photocatalytic efficacy for the removal/degradation of 2,4,6
-trichlorophenol (TCP). Results obtained using HPLC and TOC techniques showed that between 70
and 80% of the initial TCP concentration was removed/degraded after 4 h of illumination. These
results were corelated with flat, conduction and valence band potentials of synthesized pure and
binary oxides, calculated using Mott–Schottky plots.

AB  - Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, obtained by pyrolyzing the organomodified bentonites in the flow of nitrogen, were characterized using XRD, low-temperature N2 physisorption and Raman spectroscopy. Structural and textural properties of carbonized bentonites depended on the arrangement of alkylammonium cations in the paternal organomodified bentonite, while the Raman spectroscopy confirmed the presence of amorphous carbon.

abstract = "Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, obtained by pyrolyzing the organomodified bentonites in the flow of nitrogen, were characterized using XRD, low-temperature N2 physisorption and Raman spectroscopy. Structural and textural properties of carbonized bentonites depended on the arrangement of alkylammonium cations in the paternal organomodified bentonite, while the Raman spectroscopy confirmed the presence of amorphous carbon. The obtained carbonized bentonites were used for modification of the carbon paste electrode. The modified electrodes were investigated using cyclic voltammetry and electrochemical impedance spectroscopy.

AB  - Cobalt-doped alumina catalyst was synthetized using the sol-gel method, gelled and calcined at 500 °C. The synthesized material was previously fully characterized. Cobalt-doped alumina was tested as catalysts in an Orange G degradation in the presence of Oxone®. Oxone® is a precursor of radicals and the role of the investigated catalyst was to activate its decomposition. Sulfate ion radicals act as oxidizing species in dye degradation reaction. The influence of the mass of the catalyst and the reaction temperature was investigated. The catalyst mass and temperature increase were beneficial for the dye degradation rate. The pseudo-first order kinetic model was found to be the most appropriate fit for experimentally obtained data. The adsorption of the dye on Co-doped alumina was also tested, and it was found to be negligible. The investigated catalyst was found to be effective for Orange G degradation in the presence of Oxone®.

AB  - The aim of this study was to investigate the response of different alumina types modified by  cooper. Two alumina oxyhydrates with different water content, 3mol H2O/ mol Al2O3 (gibbsite) 0.6 mol H2O/ mol Al2O3 (α,γ-alumina phase), were used in this study. Copper  modified alumina samples were prepared by ion exchange with a solution of CuSO4*5H2O.  Cu-alumina samples were dried at at 110 o C overnight. The obtained samples were used as  modifiers of the carbon paste electrode. Their electrochemical response toward ferricyanide/ferrocyanide redox probe was evaluated by cyclic voltammetry and correlated  with the type of alumina and the amount of copper in impregnated alumina. The possibility of  the application of Cu-alumina as an electrochemical sensor was tested.

AB  - This work presents the investigation of electrochemical properties of three alumina samples with different structure and crystal water content. The samples were characterized by XRD and FTIR-ATR analysis, confirming the presence of trihydrate, monohydrate and anhydrous alumina. The samples were used as modifiers of carbon paste electrodes. Their electrochemical behavior toward ferricyanide/ferrocyanide redox probe was evaluated by electrochemical impedance spectroscopy and cyclic voltammetry. The electrochemical behavior toward ruthenium hexamine redox probe was investigated by cyclic voltammetry. The response toward quinone/hydroquinone redox probe was evaluated in buffered and unbuffered solution by cyclic voltammetry. It was found that the surface chemistry of investigated samples influenced their electrochemical properties.

electrochemical oxidation of 2,4,6-trichlorophenol (TCP) in order to inves tigate the influence of doping on electrochemical performance of zirconia mat rix. The techniques of cyclic voltammetry and electrochemical impedance

enhanced the activity of zirconia matrix towards TCP electrooxidation. Elec trochemical impedance spectroscopy showed the importance of iron content in 
zirconia matrix for the preferable pathway of TCP electrooxidation. The quin one formation pathway was favoured by low iron doped zirconia (doped with

Резултати електрохемијске импедансне спектроскопије су указали на утицај количине јона гвожђа у цирконијум- -оксидној матрици на реакциони механизам TCP електроосидације. Реакциона путања која укључује формирање хинона је фаворизована на цирконијум-оксидним електро- дама са ниским садржајем јона гвожђа (допираног са 1 % јона гвожђа), док је форми- рање полифенолног филма дошло до изражаја на узорцима са већим садржајем јона гвожђа (допираних са 10 и 20 % јона гвожђа). Узорак цирконијум-оксида, допиран са 5 % јона гвожђа, има прелазна својства, јер долази до формирања полифенолног филма на површини електроде, али и до његове разградње.",

AB  - Two different types of cobalt-based catalysts were synthesized and tested as Oxone®
activators in catalytic oxidation of model dye, tartrazine. First type of catalyst was cobalt
impregnated aluminum pillared montmorillonite, and the second one was cobalt-doped
alumina. Aluminum pillared montmorillonite was synthesized from Na-exchanged Wyoming
clay and impregnated with cobalt using incipient wetness impregnation method. Cobalt-doped
alumina catalysts were synthetized using the sol-gel method. Three calcination temperatures
were employed: 500 °C, 1000 °C and 1100 °C. The degradation of tartrazine was monitored
using Thermo Scientific Evolution 220 UV–Visible Spectrophotometer in the wavelength
range from 200–600 nm.In this wavelength range the monitoring of decolorization, along
with registering the emergence, followed by degradation,of detectable degradation products
was achieved. The effect of the different reaction parameters on decolorization and
degradation efficiency was tested, including the influence of the mass of catalyst, reaction
temperature and initial pH. It was found that the increase of temperature and the mass of catalysts were beneficial for the reaction.All investigated catalysts were found to be very efficient in the Oxone® initiated tartrazine decolorization and degradation.

AB  - Porous cobalt-doped alumina catalysts were synthetized using the sol-gel method. The synthesized materials were calcined at 500 °C, 1000 °C and 1100 °C and denoted as CoA-500, CoA-1000 and CoA-1100, respectively. Catalysts were characterized using XRPD, H2-TPR and low temperature N2 physisorption techniques. Applied techniques showed that the annealing temperature affects the structural and textural properties of the catalysts. The synthesized catalysts were investigated in the degradation of tartrazine in the presence of Oxone®. The influence of the mass of catalyst, reaction time, reaction temperature and initial pH were investigated. The temperature increase was beneficial for the dye degradation rate. CoA-500 was proved to be the most efficient among the investigated catalysts. The reaction followed the pseudo-first order kinetics for all investigated temperatures for all three catalysts. All cobalt-doped alumina catalysts were found to be efficient in the Oxone® induced catalytic degradation of tartrazine with CoA-500 showing the best performance.

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.

AB  - Alumina powders, pure and doped with nickel, were synthetized by sol-gel method and calcined at 500, 900 and 1100°C in order to obtain mesoporous structures with a high specific surface area, well adapTab. to catalytic application. The characterization of samples was performed by XRD, EPR spectroscopy and electrochemical impedance spectroscopy (EIS). XRD analysis showed that the addition of Ni2+, as well as the annealing temperature, affects the structural properties of the obtained composites. EPR analysis revealed the traces of Fe3+ impurities, the presence of oxy defects in alumina and Ni2+ in tetrahedral position for samples calcined at 1100°C. The impedance of the Nafion/alumina modified GCE depended on combined effect of porous structure and surface properties of alumina samples. The electrochemical behavior of a glassy carbon electrode modified with Ni (II)-doped aluminas was studied in 0.5 M NaOH solution, with and without methanol. The electrochemical activity of nickel-doped alumina composites was dictated by the amount of present NiO impurity.
AB  - Прахови алумине, без додатка и са додатком никла, синтетисани су сол-гел методом и жарени на 500, 900 и 1100 oC с циљем да се добију мезопорозне структуре са високом специфичном површином, применљиве у каталитичке сврхе. Карактеризација узорака вршена је са XRD, EPR и EIS спектроскопијом. XRD анализа показала је да и додатак Ni2+-јона, као и температура жарења, утичу на структурне особине добијених композита. EPR анализом утврђено је присуство Fe3+-јона у траговима, окси-дефеката у алумини и Ni2+-јона у тетраедарским позицијама у узорцима жареним на 1100 oC. Импеданса стакло-карбон електроде модификоване нафион/алумином, зависила је од комбинованог ефекта порозне структуре и површинских карактеристика узорака алумине. Електрохемијско понашање модификоване стакло-карбон електроде испитивано је у 0.5M раствору NaOH, без и са метанолом. Електрохемијска активност никл-алумина композита диктирана је присуством NiO фазе.

XRD analysis showed that the addition of Ni2+, as well as the annealing temperature, affects the structural properties of the obtained composites. EPR analysis revealed the traces of Fe3+ impurities, the presence of oxy defects in alumina and Ni2+ in tetrahedral position for samples calcined at 1100°C. The impedance of the Nafion/alumina modified GCE depended on combined effect of porous structure and surface properties of alumina samples. The electrochemical behavior of a glassy carbon electrode modified with Ni (II)-doped aluminas was studied in 0.5 M NaOH solution, with and without methanol. The electrochemical activity of nickel-doped alumina composites was dictated by the amount of present NiO impurity., Прахови алумине, без додатка и са додатком никла, синтетисани су сол-гел методом и жарени на 500, 900 и 1100 oC с циљем да се добију мезопорозне структуре са високом специфичном површином, применљиве у каталитичке сврхе. Карактеризација узорака вршена је са XRD, EPR и EIS спектроскопијом. XRD анализа показала је да и додатак Ni2+-јона, као и температура жарења, утичу на структурне особине добијених композита. EPR анализом утврђено је присуство Fe3+-јона у траговима, окси-дефеката у алумини и Ni2+-јона у тетраедарским позицијама у узорцима жареним на 1100 oC. Импеданса стакло-карбон електроде модификоване нафион/алумином, зависила је од комбинованог ефекта порозне структуре и површинских карактеристика узорака алумине. Електрохемијско понашање модификоване стакло-карбон електроде испитивано је у 0.5M раствору NaOH, без и са метанолом. Електрохемијска активност никл-алумина композита диктирана је присуством NiO фазе.",

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  - 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.

AB  - The disposal of waters contaminated with azo dyes into natural aquatic recipients can be
regarded as very harmful. Since dyes have a high degree of chemical and photolytic stability
adsorption can be regarded as appropriate method for dye removal. Porous alumina composites
are well known as efficient and inexpensive adsorbents of different pollutants. In this paper, the
alumina powders, pure and doped with 40 mass % nickel, were synthetized by sol-gel method
and calcined at 500 oC, 900 oC and 1100 oC in order to obtain mesoporous structures with a high
specific surface area, well adaptable to adsorption application. The obtained composites were
tested as adsorbents of textile azo dye Acid Yellow 99 (AY99). The adsorption was monitored
with respect to contact time, using AY99 initial concentrations of 50 mg dm-3, mass of adsorbent
mads=50 mg and volume of dye solution V=50 cm3. The adsorption study showed that the adsorption capacity of samples decreased with temperature of calcination and nickel content. The study confirmed the feasibility of using alumina composites as adsorbents for the azo dyes.

electron microscopy analysis of the spheres disclosed the elongated shape of sub-20 nm primary particles,
while BET analysis revealed their high surface area of 135m2/g. Anatase presence was observed in
the films based on X-ray diffractometry, selected-area electron diffraction analysis and Raman spectroscopy
analyses. Increased light scattering of the spheres in visible region was observed by UV-VIS-NIR spectroscopy.
Photovoltaic performance of the operating N719-sensitized cells was tested using electrochemical impedance

AB  - For long-term protection of stored products there is a growing demand to replace chemical insecticides due to their effects on human health and environmental safety. Particulate materials, such as inert dusts and various submicron and nanomaterials have been extensively tested as viable alternatives. This is the first study on the insecticidal impact of alumina powder (alpha-Al2O3) on the bruchid pest, Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae: Bruchinae). By altering the fuel to oxidant molar ratio (F/O: 0.5, 0.8, 1.2) in an autocombustion reaction we synthesized alumina powders with specific surface area and particle size varying from the nano- to micron scale. It was found that particle morphology influenced survival and progeny number of A. obtectus. The order of powders from low to high efficacy in reducing beetle performance (F/O-0.8  LT  F/O-0.5  LT  F/O-1.2) correlated well with increase in surface area, pore volume and diameter, and decrease in particle size. Survival was also affected by time of exposure, the applied dose and sex. The estimated median lethal concentration of the most efficient powder F/O-1.2 was significantly lower in males (LC50 = 330.4 ppm) than in females (LC50 = 409.6 ppm). Our results suggest that alumina powder can be considered for seed protection against A. obtectus, particularly during long-term storage, as it is cost effective, exerts limited toxicity to humans and demands no repetitive use like conventional pesticides.

Our results suggest that alumina powder can be considered for seed protection against A. obtectus, particularly during long-term storage, as it is cost effective, exerts limited toxicity to humans and demands no repetitive use like conventional pesticides.",

AB  - A simple bottom-up method for the preparation of novel and very efficient photocatalytic nanocomposite system based on carbonized form of polyaniline (PANI) and colloidal TiO2 nanocrystals has been developed. The carbonized PANI/TiO2 nanocomposites were synthesized in a two-step procedure. Firstly, non-carbonized PANI/TiO2 nanocomposites were synthesized by the chemical oxidative polymerization of aniline (ANI) with ammonium peroxydisulfate, in the presence of colloidal TiO2 nanoparticles (TiO2 NPs) (d 4.5 nm). Initial [TiO2 NANI] mole ratios were 20, 50, and 80. In the second step, following the polymerization process, the carbonization of PANI/TiO2 nanocomposites was performed by thermal treatment in an inert atmosphere at 650 degrees C. The morphological and structural properties of the carbonized nanocomposites were studied using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Raman spectroscopy. The accomplishment of complete carbonization of PANI in PANI/TiO2 nanocomposites was confirmed by Raman spectroscopy. The appearance of anatase and rutile crystal forms in TiO2 NPs upon carbonization, with mass ratio depending on the initial molar ratio of ANI and TiO2 NPs was revealed by XRD measurements, TEM, SEM and Raman spectroscopy. The photocatalytic activities of carbonized PANI/TiO2 nanocomposites were evaluated following the photocatalytic degradation processes of Rhodamine B and Methylene blue. Carbonized PANI/TiO2 nanocomposites showed higher photocatalytic efficacy compared to bare TiO2 NPs and non-carbonized PANI/TiO2 nanocomposites. The porosity and surface structure of carbonized PANI/TiO2 nanocomposites, as well as crystalline structure of TiO2, affect photocatalytic activity of nanocomposites.
