AB  - In this article partial and complete substitution of cations in the interlayer region of clay with different amounts of hexadecyl trimethylammonium bromide (HDTMABr) was performed. The aim was to investigate the influence of HDTMA/bentonite ratio on phenol electrooxidation. Multisweep cyclic voltammetry was applied to analyze the behavior of clay modified glassy carbon electrode. The influence of phenol concentration was investigated. HDTMA/clay ratio plays key role in phenol oxidation on these electrodes. There is definite amount of surfactant that should be present in bentonite sample in order to achieve good current response and prolonged life of the electrode. The reaction order in respect to phenol was determined to be around 2.

AB  - NaX zeolite was modified by platinum via impregnation/thermal decomposition technique, using Pt(II)-acetyl acetonate in acetone as an impregnating solution. The samples were characterized by scanning electron microscopy (SEM) and cyclic voltammetry methods. The mixture of modified zeolite and 10 wt.% of carbon black, in a form of thin layer, was pasted to a glassy carbon surface. With this mixture as the electrode material, oxidation of hydroxide ions was studied by cyclic voltammetry. The response of modified zeolite electrodes was compared with bare platinum electrode and platinum electrode covered with Nafion film.

AB  - Zeolite NaX was modified by Pt and Pt/Ru nanodispersed metallic clusters. This modification was achieved by zeolite impregnation with acetylacetonate salt/acetone solution, followed by acetone evaporation and thermal decomposition of organometallic complex. Samples characterization was performed by X-ray diffraction analysis, nitrogen adsorption-desorption measurements and Raman spectroscopy. The incorporation of metal into zeolite cavities induced the amorphisation of the zeolite framework on the local level. The mixture of modified zeolite and 10 wt% of carbon black, in a form of thin layer, was pasted to a glassy carbon surface by Nafion. Electrocatalytic properties of metal-modified zeolites were tested in CO electrooxidation reaction. The mutual influence between Pt and Ru atoms enhanced electroactivity of Pt/Ru-modified zeolite toward carbon monoxide electrooxidation. The behavior of untreated 13X zeolite was investigated under the same condition in order to asses the influence of the support. Gradual deactivation of 13X electrode occurred.

AB  - Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, inexpensive methods to identify p-NP in water, however, is lacking. In the present study, an electrochemical technique using clay-modified electrodes to measure p-NP was investigated as a potentially promising method to fill that gap. A glassy carbon electrode (GCE) was modified with a thin layer of Na-enriched bentonite and a series of benzyltrimethylammonium (BTMA(+))-bentonites (BTMA(+)-B) in order to confirm these materials as p-NP electrosensitive. A series of organobentonites was synthesized using different BTMA(+)/bentonite ratios. The materials obtained were characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, and a low-temperature nitrogen adsorption-desorption method. A monolayer arrangement of BTMA(+) within the interlamellar region of beidellite-rich smectite was confirmed. Deterioration of the textural properties was observed with increase of BTMA(+). loading. The electro-oxidation of p-NP in an acidic medium on BTMA(+)-B-modified GCE was investigated. The cyclic voltammetry method with a three-electrode cell was used. The reference electrode was Ag/AgCl in 3 M KCl and a Pt foil was the counter electrode. For each electrochemical measurement, a different BTMA(+) loading in BTMA(+)-B was used as the material for GCE coating and applied as the working electrode. The electrochemical activity of BTMA(+)-B-based electrodes increased with BTMA(+) loading. The results confirmed that the organophylic character of the BTMA(+)-B-modified surface was the main influence on the electrochemical activity of the BTMA(+)-B-based GCE; the influence of textural properties was almost negligible. The increased electrode activity toward p-NP was achieved by the adsorption of p-NP on the electrode surface, the process that commonly precedes the electro-oxidation. The present study showed that synthesized materials could potentially be used in an electrochemical test for the presence of p-NP in water solutions.

abstract = "Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, inexpensive methods to identify p-NP in water, however, is lacking. In the present study, an electrochemical technique using clay-modified electrodes to measure p-NP was investigated as a potentially promising method to fill that gap. A glassy carbon electrode (GCE) was modified with a thin layer of Na-enriched bentonite and a series of benzyltrimethylammonium (BTMA(+))-bentonites (BTMA(+)-B) in order to confirm these materials as p-NP electrosensitive. A series of organobentonites was synthesized using different BTMA(+)/bentonite ratios. The materials obtained were characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, and a low-temperature nitrogen adsorption-desorption method. A monolayer arrangement of BTMA(+) within the interlamellar region of beidellite-rich smectite was confirmed. Deterioration of the textural properties was observed with increase of BTMA(+). loading. The electro-oxidation of p-NP in an acidic medium on BTMA(+)-B-modified GCE was investigated. The cyclic voltammetry method with a three-electrode cell was used. The reference electrode was Ag/AgCl in 3 M KCl and a Pt foil was the counter electrode. For each electrochemical measurement, a different BTMA(+) loading in BTMA(+)-B was used as the material for GCE coating and applied as the working electrode. The electrochemical activity of BTMA(+)-B-based electrodes increased with BTMA(+) loading. The results confirmed that the organophylic character of the BTMA(+)-B-modified surface was the main influence on the electrochemical activity of the BTMA(+)-B-based GCE; the influence of textural properties was almost negligible. The increased electrode activity toward p-NP was achieved by the adsorption of p-NP on the electrode surface, the process that commonly precedes the electro-oxidation. The present study showed that synthesized materials could potentially be used in an electrochemical test for the presence of p-NP in water solutions.",

AB  - In order to enhance nickel effectiveness for methanol oxidation reaction, zeolite type 13X was used as a support for nickel nanodispersion. Nickel modified samples were characterized by XRD, SEM and nitrogen adsorption-desorption measurements. The incorporation of nickel into zeolite cavities led to the partial destruction of the zeolite framework. Modified zeolite was used as the electrode material for methanol oxidation in a deaerated 0.1 M NaOH aqueous solution. It showed similar electrochemical behavior to that of polycrystalline nickel. The destruction of zeolite structure probably enabled aluminum from the framework to stabilize alpha-Ni(OH)(2). Mixture of beta- and gamma-NiOOH was obtained at the 13XNi100 electrode after cycling in alkaline solution. It was concluded from the electrochemical measurements that beta-NiOOH was preferable oxide form for methanol oxidation. Copyright

AB  - The partial and complete substitution of cations in the interlayer region of clay with different amounts of hexadecyl trimethylammonium bromide (HDTMABr) was performed. The aim was to synthesize organo-bentonites to be used as constituents of porous electrodes for the electrooxidation of phenol. Domestic clay from Bogovina was subjected to a common procedure of the production of organo-bentonites. It included the following steps: grinding, sieving, Na-exchange, cation exchange and drying. The samples were characterized by X-ray diffraction (XRD) analysis, while the textural properties were evaluated by nitrogen physisorption. The multisweep cyclic voltammetry was applied to analyze the behavior of the clay modified glassy carbon electrode. The influences of the surfactant loading and pH of the support electrolyte were investigated. Rapid deactivation of electrodes occurred in an acidic environment, while good stability of the investigated electrodes was obtained in alkaline medium.

AB  - Bentonite was modified by the exchange of inorganic cations with hexadecyl trimethylammonium, dodecyl trimethylammonium or tetramethylammonium cation. The obtained materials were characterized by physisorption of nitrogen and X-ray diffraction analysis. Multisweep cyclic voltammetry was applied to analyze phenol response on different organo bentonite-based electrodes. The aim of the investigation was to determine the influence of the type of modifying agent on the electrochemical performance of the investigated electrodes. All electrodes exhibited similar electrochemical behavior but with different intensities of the electrochemical response and Tafel slopes. The difference in Tafel slopes reflected different level of involvement of pores in the phenol electrooxidation.

AB  - The kinetics of the isothermal adsorption of ethanol from an aqueous solution onto a hydrophobic zeolite of the NaZSM-5 type in the temperature range 298-333 K was investigated. Specific shape parameters of the adsorption degree curves were determined. The changes in the specific shape parameters of the adsorption degree curves with temperature were determined. The kinetic parameters of ethanol adsorption (E-a, ln A) were determined by the initial rate, the saturation rate and the maximum rate methods as well as from the Johnson, Mehl and Avramy equation. The kinetic model of ethanol adsorption kt=[1-(1-alpha)(1/3)] was determined by the "model fitting" method. Ethanol adsorption from aqueous solution onto NaZSM-5 is a kinetically controlled process limited by the rate of three-dimensional movement of the boundary layer of the adsorption phase. A model for the mechanism of ethanol adsorption onto NaZSM-5 is suggested on the basis of the kinetic model. Ethanol molecules in aqueous solution are associated in clusters. The activation energy of the adsorption process corresponds to the energy required for the detachment of an ethanol molecule from a cluster and its adsorption onto the zeolite.

AB  - From aqueous solutions, gold was deposited on freshly polished titanium surface either by displacement reaction or by potentiodynamic polarization. Both of these procedures resulted in the formation of Au/TiO2 composite layer over the titanium surface, although with quite different Au content. The electrochemical behaviour of these composite layers was examined in 0.1 M NaOH solution, both oxygen free and oxygen saturated, using rotating disc technique. In the potential region of oxygen reduction reaction, the Au/TiO2 layer obtained by potentiodynamic polarization, displayed the voltammetric curve similar to that observed on (1 0 0) plane of Au monocrystal. The Koutecky-Levich analysis evidenced that 4e- route of oxygen reduction dominates on both type of composite layers.

AB  - The nanostructure and textural properties of acid-activated bentonite clays from the Bogovina coalmine were investigated. The acid activation was performed with HCl in the concentration range 1.5-7.5 M. The atomic force microscopy followed by image analysis was used in order to establish the influence of the acid treatment on the size of bentonite particles. Nitrogen adsorption-desorption isotherms at -196 degrees C were used to estimate the specific surface area, pore volume and pore size distribution. The acid treatment reduces the size of bentonite particles and increases the specific surface area and pore volume of the investigated bentonites. These effects are improved by increasing the acid concentration up to 4.5 M HCl Further increase in acid concentration does not result in development of new porous structure.

abstract = "The nanostructure and textural properties of acid-activated bentonite clays from the Bogovina coalmine were investigated. The acid activation was performed with HCl in the concentration range 1.5-7.5 M. The atomic force microscopy followed by image analysis was used in order to establish the influence of the acid treatment on the size of bentonite particles. Nitrogen adsorption-desorption isotherms at -196 degrees C were used to estimate the specific surface area, pore volume and pore size distribution. The acid treatment reduces the size of bentonite particles and increases the specific surface area and pore volume of the investigated bentonites. These effects are improved by increasing the acid concentration up to 4.5 M HCl Further increase in acid concentration does not result in development of new porous structure.",
