AB  - As electrode materials, graphene and its derivatives have been the subject of extensive investigation. Graphene has been modified by various types of materials in an effort to enhance its electrode qualities even more. This work sought to understand how the precursor to graphene affected the electrochemical characteristics of the final product and its potential use, unaltered, in the creation of sensors for nitrophenol derivatives. A set of samples of graphene produced using a radiofrequency (RF) thermal plasma jet are presented. Precursors for the creation of graphene included six basic organic compounds: alkanes, alcohols, carboxylic acids, and aldehydes. Cyclic voltammetry (CV) was used to carry out the electrochemical characterization. Square wave voltammetry (SWV) was used to assess the graphene’s electroanalytical performance for the simultaneous detection of 3-nitrophenol and 4-nitrophenol. A graphene sample made from methane had the maximum current response. Using as synthesised methane-originated graphene, two nitrophenol derivatives were successfully detected simulta neously in a concentration range of 10 μM to 500 μM. The type of oxygen functional groups and the edge/plane ratio in the produced graphene were shown to have a significant impact on the graphene electroactivity. Future research ought to focus on improving synthetic conditions in order to enhance desirable characteristics.

AB  - Bentonite clay has shown to be a versatile material that can be easily modified and applied as 
an adsorbent, (electro)catalyst, or as a support for (electro)catalyst. The carbon-clay composites combine a relatively high specific surface area of the clay with a good electrical conductivity of carbon.In this paper, the effect of the applied carbonization procedure on the electrochemical properties of bentonite-carbon composite was investigated. Chitosan-modified bentonite was carbonized by conventional thermal degradation and by the hydrothermal procedure. The electrochemical characterization was performed by cyclic voltammetry and electrochemical impedance spectroscopy. The response to Fe(CN)63-/4- and Ru(NH3)62+/3+ redox probe showed that the thermally treated sample shows somewhat higher electrochemical activity and lower charge-transfer resistance. However, an investigation of composites activity toward 
 minophenazone, performed in the pH range 3-9 showed that the hydrothermally obtained sample shows higher activity at pH above 5, while the thermally obtained sample was more active at pH below 5.

AB  - Nowadays, environmental pollution caused by antibiotics attracts extensive attention.
Adsorption has been successfully applied in the treatment of wastewater loaded by
pharmaceutics, while diverse natural and eco-friendly materials have been recognized as
promising adsorbents. In this work smectite clay from Bogovina (Serbia) and biopolymer
chitosan (derived from waste of crustaceans) were used as eco-friendly starting materials for
the adsorbent synthesis. The combination of transition metal, carbon materials, and clay
minerals represents a useful way to develop functional nanocomposites with benefiting
synergistic properties of all components.
Simple, one-step hydrothermal procedure conducted at 180 ℃ for 24h was applied for
synthesis of cobalt/smectite/chitosan-derived carbon (H_Co/C-S) nanocomposite. The sample
was characterized using XRPD, FTIR, and low-temperature N2-physisorption analysis and
tested as adsorbent of ciprofloxacin (CPX). The effects of temperature, initial pH, and CPX
concentration on the adsorption process were investigated. The adsorption results were fitted
by Langmuir, Freundlich, and Sips adsorption isotherms. Additionally, CPX adsorption was
described by appropriate kinetics and thermodynamic parameters. It was found that
temperature increase had the beneficial effect on CPX adsorption, while investigated
adsorbent was efficient in a broad pH range (4-8). The H_Co/C-S adsorbent was found to be
efficient in the removal of CPX antibiotic.

AB  - The employment of compounds obtained from natural sources to produce adsorbents and their application in the elimination of antibiotics from industrial effluents have gained significant attention because of their low production cost and sustainability. Herein, chitosan (biopolymer) and smectite (abundant clay mineral) were used for the low-cost and eco-friendly synthesis of a new type of adsorbent. A low-energy-consumption hydrothermal process was applied to the synthesis of the chitosan-derived carbon–smectite nanocomposite with cobalt (H_Co/C-S). The produced nanocomposite was characterized using elemental analysis, ICP-OES, XRPD, low-temperature N2 adsorption–desorption isotherms, FTIR analysis, and point of zero charge. H_Co/C-S (SBET = 0.73 m2 g−1, d001 = 1.40 nm, pHPZC = 5.3) was evaluated as a ciprofloxacin adsorbent in aqueous solution. Experimental data were fitted with different kinetic models and interpreted by selected adsorption isotherms. The pseudo-second-order model was found to be the most appropriate, while ciprofloxacin adsorption onto H_Co/C-S was best described by the Redlich–Peterson isotherm (R2 = 0.985). The maximum adsorption capacity of H_Co/C-S, according to the Langmuir isotherm (R2 = 0.977), was 72.3 mg g−1. Desorption and thermodynamic studies were performed. The obtained results indicated that the new hierarchically designed H_Co/C-S has promising potential to be further tested for application in real wastewater treatment.

abstract = "The employment of compounds obtained from natural sources to produce adsorbents and their application in the elimination of antibiotics from industrial effluents have gained significant attention because of their low production cost and sustainability. Herein, chitosan (biopolymer) and smectite (abundant clay mineral) were used for the low-cost and eco-friendly synthesis of a new type of adsorbent. A low-energy-consumption hydrothermal process was applied to the synthesis of the chitosan-derived carbon–smectite nanocomposite with cobalt (H_Co/C-S). The produced nanocomposite was characterized using elemental analysis, ICP-OES, XRPD, low-temperature N2 adsorption–desorption isotherms, FTIR analysis, and point of zero charge. H_Co/C-S (SBET = 0.73 m2 g−1, d001 = 1.40 nm, pHPZC = 5.3) was evaluated as a ciprofloxacin adsorbent in aqueous solution. Experimental data were fitted with different kinetic models and interpreted by selected adsorption isotherms. The pseudo-second-order model was found to be the most appropriate, while ciprofloxacin adsorption onto H_Co/C-S was best described by the Redlich–Peterson isotherm (R2 = 0.985). The maximum adsorption capacity of H_Co/C-S, according to the Langmuir isotherm (R2 = 0.977), was 72.3 mg g−1. Desorption and thermodynamic studies were performed. The obtained results indicated that the new hierarchically designed H_Co/C-S has promising potential to be further tested for application in real wastewater treatment.",

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.

composites with higher zirconia content are characterized by peaks of the tetragonal zirconia 
phase. On the basis of the calculated flat band potentials from Mott-Schottky plots and optical 
band gaps, the conduction and valence band potentials were estimated for the composite 
semiconductors. Photocatalytic activity of synthesized samples in the process of degradation 
of trichlorophenol was obtained and correlated with band potentials and optical properties.

AB  - 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. The electrosorption of chloride and sulfate anions on carbonized bentonites was studied by chronocoulometry. The results were interpreted in the terms of surface groups and textural properties of the carbonized bentonites.
AB  - Органомодификовани бентонити су добијени модификацијом бентонита из локалног рудника Боговина са четири различита алкиламонијум јона у количини која је једнака његовом капацитету јонске измене.

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. The electrosorption of chloride and sulfate anions on carbonized bentonites was studied by chronocoulometry. The results were interpreted in the terms of surface groups and textural properties of the carbonized bentonites., Органомодификовани бентонити су добијени модификацијом бентонита из локалног рудника Боговина са четири различита алкиламонијум јона у количини која је једнака његовом капацитету јонске измене.

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  - Alumina (aluminium oxide or Al2O3) is one of the well-known ceramic materials. This 
material is widely used as abrasives, in the production of refractory products and glass, 
advanced ceramics, medical applications, and military and electronics applications. It is also 
used as a catalyst and/or catalyst support for various catalytic reactions. Alumina found its 
various applications in the field of electrochemistry as well: as solid electrolyte, anodic 
membrane, and corrosion coatings are the most prominent of them.
Most intriguingly, alumina although known as an insulating material, is also used as the 
electrode material. In recent years it was noticed that the properties of the glassy carbon 
electrode were enhanced after polishing the electrode with γ-alumina. The morphology and 
structure of Al2O3 particles used for the electrode polishing influenced electrode 
performances. The investigations were continued with the alumina applied at the surface of 
the electrode. Strong apparent catalysis of the catechol redox process was noticed in the 
presence of alumina on the electrode surface leading to the conclusion that the alumina on the 
electrode surface can act as a catalyst for oxidative process involving a proton-coupled 
electron-transfer process.

AB  - Solvothermaly synthesized zirconium oxide nanopowders, pure and 
doped with various amounts of iron ions (1–20 %), were used as modifiers of 
glassy carbon electrodes. The modified electrodes were tested in the reaction of 
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 
spectroscopy were employed. Cyclic voltammetry showed that electrooxid ation of TCP proceeded through the oxidation of hydroxyl group. Possible 
pathway included the formation of quinones and the formation of polyphenol 
film on the electrode surface, leading to the electrode fouling. Iron doping 
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 
1% of iron), while polyphenol film formation on the electrode surface was 
more pronounced at samples with higher iron ion content (for doping with 10 
and 20 % of iron). The sample with 5 % of added iron ions, showed intermed

AB  - This paper presents a new two-step method for the synthesis of NiO/TiO2–CeO2 semiconductors, which implies, the first, the mechanochemical synthesis of TiO2–CeO2 support, and the second is the doping of different NiO contents by chemical precipitation in an aqueous medium in an ambient atmosphere. Structural, optical, electrochemical and photocatalytic properties of NiO/TiO2–CeO2 semiconductors were examined. The influence of different NiO contents on the electrocatalytic activity of NiO/TiO2–CeO2 samples was investigated in the oxygen evolution reaction and the results showed that the samples with the lowest NiO content have the highest electroactivity. The photocatalytic activity was determined during the phenol decomposition process over the samples with different NiO:TiO2–CeO2 ratios and the best photocatalytic activity is observed for the sample with 4.1 mol% NiO. The sample with the lowest NiO content obtained by a relatively simple method is suitable for use both as an electrode material in the oxygen evolution reaction and as a photocatalyst in the phenol decomposition process.

AB  - Montmorillonite based clay was acid activated. Nicotine was adsorbed on untreated
and acid activated clay from its aqueous solution at either pH=6 or pH=9.26 (unadjusted pH
solution). The XRD analysis revealed that the 001 basal spacing of montmorillonite after
nicotine adsorption was around 1.38 nm, regardless of clay treatment or pH of adsorption.
The obtained values for basal spacing indicate that nicotine is in monolayer arrangement. In
order to investigate electrochemical properties, untreated and acid activated clay, with and
without nicotine, were used as modifier of carbon paste electrode. Cyclic voltammetry and
electrochemical impedance spectroscopy were employed to study electrochemical response of
clay-modified electrodes toward ferrocyanide probe. The nicotine-modified untreated clay
used as paste electrode showed enhanced electrochemical response toward ferrocyanide
probe in comparison to electrode based on clay without nicotine. On the other hand,
adsorbed nicotine on acid activate clay resulted in lower electrode activity. Electrochemical
response of adsorbed nicotine was studied at different pH. Nicotine oxidation at each of
investigated samples followed the same trend regardless of clay treatment or pH at which
adsorption was performed. For all samples, nicotine oxidation peak potential showed linear
dependence on pH in pH range from 3.7 to 9.0, with slopes close to the value of 59 mVdec-1
expected for equal number of protons and electrons involved in the reaction. The nicotine
reduction process was best resolved at pH = 1 at potential around -1.35 V, while the
following cathodic wave observed at potential around -1.5 V was ascribed to the cathodic
hydrogen reduction. Mechanism of electrochemical oxidation was not influenced by pH of
adsorption, i.e., nicotine form. The amount of adsorbed nicotine was not correlated with the
electrochemical activity suggesting that only small number of adsorbed nicotine was involved
in electrochemical response.

AB  - Alumina oxyhydrates have different structural and textural properties, as well as different density of surface functional groups. Three alumina oxyhydrates with different water content, 3mol H2O/ mol Al2O3 (gibbsite), 1mol H2O/ mol Al2O3 (boehmite) and 0.6 mol H2O/ mol Al2O3 (α,γ-alumina phase), were used in this study. The samples were used as modifiers of carbon paste electrode. Their electrochemical behavior toward ferricyanide/ferrocyanide redox probe was evaluated by electrochemical impedance spectroscopy and cyclic voltammetry. 
 Ferricyanide/ferrocyanide redox system has a well-known electrochemical behavior and is sensitive to the changes occurring at the electrode surface. The lowest charge transfer resistance was obtained for α,γ-alumina phase. The redox process of ferri/ferro redox probe on investigated electrodes exhibited a quasi-reversible behavior, since the obtained values of peak-to-peak separation are greater than 59 mV value expected for a reversible process. The response toward quinone/hydroquinone redox probe was evaluated by cyclic voltammetry in buffered solutions at various pH. Gibbsite and boehmite showed expected response, while the surface groups of α,γ-alumina phase enabled quinone oxidation to proceed through two pathways simultaneously.

abstract = "Alumina oxyhydrates have different structural and textural properties, as well as different density of surface functional groups. Three alumina oxyhydrates with different water content, 3mol H2O/ mol Al2O3 (gibbsite), 1mol H2O/ mol Al2O3 (boehmite) and 0.6 mol H2O/ mol Al2O3 (α,γ-alumina phase), were used in this study. The samples were used as modifiers of carbon paste electrode. Their electrochemical behavior toward ferricyanide/ferrocyanide redox probe was evaluated by electrochemical impedance spectroscopy and cyclic voltammetry. 
 Ferricyanide/ferrocyanide redox system has a well-known electrochemical behavior and is sensitive to the changes occurring at the electrode surface. The lowest charge transfer resistance was obtained for α,γ-alumina phase. The redox process of ferri/ferro redox probe on investigated electrodes exhibited a quasi-reversible behavior, since the obtained values of peak-to-peak separation are greater than 59 mV value expected for a reversible process. The response toward quinone/hydroquinone redox probe was evaluated by cyclic voltammetry in buffered solutions at various pH. Gibbsite and boehmite showed expected response, while the surface groups of α,γ-alumina phase enabled quinone oxidation to proceed through two pathways simultaneously. The surface chemistry of investigated samples influenced their electrochemical properties.",
