AB  - In this work, corrosion behavior of cooper in corrosion media consisted of aerated aqueous electrolyte of 3% NaCl with addition of different amount of cynarae extract as green corrosion inhibitor, is presented. Techniques used in this study involved open circuit measurements, evaluation of charge transfer resistance and corrosion current density during exposure to corrosion environment. Also, electrochemical impedance spectroscopy measurements are presented. Potentiodymamic polarization curves were also used for the evaluation of the corrosion current density and corrosion potential of coper in corrosion media. Based on these results, it was concluded that the satisfactory results of corrosion inhibition exceeding 70 % were obtained with small amount of only 37*10-2 of mas. % of cynarae extract, based on open circuit behavior which involved decrease of the open circuit potentials of copper in the presence of cynarae extract it was concluded that this extract served as cathodic inhibitor.
AB  - Koroziono ponašanje bakra u aerisanom vodenom rastvoru 3% NaCl bez i sa dodatkom različite količine ekstrakta cynarae (artičoka) je ispitano u cilju evaluacije inhibicije korozije bakra i mogućnosti primene ekstrakta cynarae kao zelenog inhibitora korozije. Za evaluaciju efikasnosti zaštite korišćene su uobičajene eksperimntalne tehnike praćenja potencija otvorenog kola, otpornosti prenosa naelektrisanja i struje korozije u vremenu kao i spektroskopija elektrohemijske impedancije. Ustanovljeno je da veoma male količine ovog inhibitora od svega 37*10-2 mas. % pružaju zadovoljavajuću zaštitu od korozije u 3% NaCl. Na osnovu smanjenja potencijala otvorenog kola bakra u prisustvu ekstrakta cynarae, ustanovljeno je da je inhibitor katodnog tipa.

AB  - Intrinsically conducting polymers, especially polyaniline (PANI), are widely investigated in the field of energy storage and conversion due to the highly reversible electrochemistry of doping/dedoping. These reactions are responsible for PANI’s high capacitance, often reported as pseudocapacitance. In this work, PANI electrodes were obtained by electrochemical polymerization of aniline monomer, with different polymerization charges ranging between 0.125 and 1.0 mA cm-2, on a graphite electrode, at the constant current density of 2.0 mA cm-2. The electrolyte used in this study consisted of 1.0 mol dm-3 H2SO4 and 0.2 mol dm-3 aniline. Electrochemical characterization of the PANI electrode involved cyclic voltammetry, chronopotentiometric charge/discharge and electrochemical impedance spectroscopy at constant potentials. Specific capacitance was determined from these techniques following the procedure for pseudocapacitive electrodes. After 250 cycles of charge/discharge with the current density of 10 mA cm-2, only 7 % of the capacitance was lost, indicating good stability of PANI that likely originates from its structure comprising a shared divalent sulfate ion between two monomer units.
AB  - Elektroprovodni polimeri, prvenstveno polianilin (PANI), su intenzivno proučavani u oblasti konverzije i skladištenja električne energije, zahvaljujući visokoj reverzibilnosti reakcije dopovanja/dedopovanje. Ove reakcije su odgovorne za visoku specifičnu kapacitivnost PANI koja se često u literaturi označava kao pseudokapacitivnost. U ovom radu, elektrode na bazi PANI dobijene su oksidativnom elektrohemijskom polimerizacijom anilina različitim kapacitetima polimerizacije u opsegu od 0,125 do 1,0 mA cm-2 na elektrodi od grafita u galvanostatskim uslovima gustinom struje od 2,0 mA cm-2. Kao elektrolit korišćen je vodeni rastvor 1,0 mol dm-3 H2SO4 uz dodatak 0,2 mol dm-3 anilina. Za elektrohemijsku karakterizaciju elektrode na bazi PANI korišćene su tehnike ciklične voltametrije, hronopotenciometrijskog snimanja krivih punjenja/pražnjenja i spektroskopija elektrohemijske impedanse na konstantnom potencijalu. Specifična kapacitivnost PANI elektrode određivana je na način uobičajen za pseudokapacitivne elektrode. Na osnovu 250 sukcesivnih ciklusa punjenja i pražnjenja gustinom struje od 10 mA cm-2, utvrđeno je gubitak kapacitivnosti od svega 7%, što se verovatno može dovesti u vezu sa povećanom stabilnošću PANI usled strukture koja podrazumeva deljenje dvovalentnog sulfatnog jona između dve jedinice monomera.

Optimal conditions for copolymerization were set to the current density of 0.75 mA cm-2 and the electrolyte containing 0.15 mol dm-3 aniline and 0.10 mol dm-3 sulfanilic acid. Electrochemical characterization of the poly(aniline-co-(sulfanilic acid)) electrode was performed using cyclic voltammetry and galvanostatic charge/discharge techniques. Electrical properties such as specific power and specific energy at different discharge currents were also determined. Based on the Ragon plot, it was observed that the poly(aniline-co-(sulfanilic acid)) electrode exhibited battery features at low discharge currents. In contrast, it was possible to achieve specific power of supercapacitors at high discharge currents. Moreover, after 4000 cycles of charge/discharge poly(aniline-co-(sulfanilic acid)), capacity retention exceeding 90 % was obtained.

AB  - Polyaniline (PANI), due to its highly reversible electrochemistry with superior energy storage and delivery characteristics, is considered as an electrode material in batteries, capacitors, and hybrid systems. We used a facile electrochemical synthesis for the formation of the PANI electrode using galvanostatic polymerization of aniline on the graphite electrode at the current density of 2.0 mA cm−2 from the aqueous electrolyte containing 0.25 mol dm−3 aniline and 1.0 mol dm−3 H2SO4. Electrochemical and electrical characterization suggested excellent energy storage features of the PANI electrode in a three-electrode system with specific energy up to 53 Wh kg−1 and specific power up to 7600 W kg−1. After 2000 successive charge/discharge cycles at 9.5 Ag−1, the PANI electrode retained 95% of the initial capacity, with practically unaltered Coulombic efficiency of nearly 98%, providing a good base for future studies and practical applications.

AB  - The initial corrosion behavior of AZ63 magnesium alloy was investigated in 1, 3, 5 and 7 wt.% NaCl solutions by means of corrosion potential, linear polarization, electrochemical impedance spectroscopy, and polarization measurements, during exposure in the corrosion media. Results show that the increase in chloride concentration provokes an increase in the corrosion rate. Based on the obtained kinetics parameters the mechanisms of anodic dissolution and hydrogen evolution reactions were discussed, and kinetic models were proposed. It is concluded that anodic dissolution proceeds under Temkin conditions and hydrogen evolution reaction depends on the surface coverage of Mg(OH)2 species.

AB  - Electrochemical synthesis was used to polymerize aniline and copolymerize aniline and m-aminobenzoic from aqueous acidic electrolyte containing aniline and aniline with different amount of m-aminobenzoic acid. These materials were obtained galvanostatically at graphite electrode at current density of 1.0 mA cm-2 from aqueous electrolyte containing 1.0 mol dm-3 HCl and different amount of monomers. The effect of self-doping due to meta positioned carboxylic group was observed in both synthesis parameters, morphology, degree of oxidation and electrochemical behaviour. The presence of m-aminobenzoic acid led higher copolymerization increasing with the increase of amount of m-aminobenzoic acid if comparing to polymerization potential of aniline. Moreover, the copolymer with equal amount of aniline/m-aminobenzoic acid showed electrochemical activity in neutral electrolyte which might be due to possibility of proton exchange process which can be expelled from the copolymer during oxidation process together by insertion of anions, making this material promising for use in electrochemical biosensors.

Uticaj samo-dopovanja koji je posledica prisustva karboskilne grupe u meta položaju ispoljavao se u različitim parametrima sinteze, morfologiji dobijenih materijala, stepenu oksidacije i elektrohemijskom ponašanju.

Kopolimer koji je dobijen iz elektrolita sa jednakim molskim odnosom anilina i m-aminobenzoeve kiseline pokazao je elektrohemijsku aktivnost u neutralnom elektrolitu koja može biti posledica razmene protona što ovaj materijal čini perspektivnim za praktičnu primenu u elektrohemijskim biosenzorima.

AB  - Electrochemical oxidative polymerization at constant current density was used to produce polypyrrole (PPY) at graphite electrode from aqueous acidic electrolyte containing 0,1 mol dm-3 pyrrole and 1,0 mol dm-3 HCl. PPY electrode was than used as cathode while zinc electrode served as anode in electrochemical cell with an aqueous electrolyte containing 2,0 mol dm-3 NH4Cl and 1,1 mol dm-3 ZnCl2. The relevant electrochemical parameters of this cell were evaluated from electrochemical experiments. It was observed that charge of Zn|PPY cell started at voltage between 0,5 and 0,7 V and proceeded up to 1,5 V. Charge/discharge of the cell was dependent on charge/discharge current density with open circuit voltage of the fully discharged cell around 1,3 V. The estimated values of specific energy were between 46 and 68 W h kg-1 while specific power values were between 125 and 380 W kg-1, which suggested that Zn|PPY cell had “supercapaterry” behavior.
AB  - Elektroda na bazi polipirola (PPY) dobijena je elektrohemijskom oksidativnom polimerizacijom na grafitnoj elektrodi u uslovima konstantne gustine struje. Kao elektrolit za sintezu, korišćen je vodeni rastvor 0,1 mol dm-3 pirola i 1,0 mol dm-3 HCl. Formirana je elektrohemijska ćelija u kojoj je elektroda na bazi PPY korišćena kao katoda dok je anoda bila elektroda od cinka, a elektrolit se sastojao od vodenog rastvora 2,0 mol dm-3 NH4Cl i 1,1 mol dm-3 ZnCl2. Procena relevantnih elektrohemijskih i električnih parametara ove ćelije bazirana je na elektrohemijskim eksperimentima. Utvrđeno je da je proces punjenja/pražnjenja zavisio od struje punjenja/pražnjenja, punejnje ćelije započinje na naponu između 0,5 i 0,7 V, a završava se na naponu od oko 1,3 V. Procenjene vrednosti energije bile su između 46 i 68 W h kg-1, dok se za specifičnu snagu dobijaju vrednosti između 125 i 380 W kg-1, što ukazuje na superkapabaterijska svojstva Zn|PPY ćelije.

AB  - Poly(o-toluidine) (POT) is electrochemically synthesized on graphite electrode at
constant current density of 1.5 mA cm-2 from aqueous electrolyte of 1.0 mol dm-3 H2SO4 and
0.25 mol dm-3 o-toluidine. Electrochemical characterization of POT electrode is performed
using cyclic voltammetry, Mot Schottky analysis and galvanostatic measurements at different
currents. POT electrode exhibited high energy storage features, with specific energy up to
17.5 Wh kg-1 and specific power up to 3300 W kg-1. Cyclic stability exceeding 90% is
obtained over 2000 charge/discharge cycles at 13.1 A g-1 indicating the perspective
application of POT electrode as energy storage material.

The discharge capacity of the polypyrrole in the chloride-based electrolyte (for the Zn|PPy cell) is in the range 110 mAh g −1 of PPy, while in the sulfate-based electrolyte ∼150 mAh g −1 of PPy (for the PbSO 4 |PPy and PPy|PbO 2 cells), which is close to the theoretically calculated values. Electrochemical and electrical parameters, reactions in the cells, specific capacity, specific capacitance, energy, and power, for the Zn|PPy, PPy|PbO 2 and PbSO 4 |PPy cells are determined. In addition, the energy efficiency, for the considered systems is estimated.

AB  - Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of α-amylase from Bacillus licheniformis. The formation of a polyaniline layer (PANI) on MAG particles was achieved by chemical polymerization of aniline. Immobilization was carried out by adsorption, as a simple, inexpensive and fast method that allows retention of a large portion of the initial activity of the immobilized enzyme. FTIR spectroscopy was used to characterize the obtained particles and to confirm changes dueto formation of a PANI layer and conjugation of α-amylase on the particle surfaces. Particle size distribution was bimodal and three-modal for MAG and MAG-PANI, respectively. Appearance of a fraction of smaller MAG-PANI particles than MAG particles could be attributed to the formation of PANI particles without the MAG core. Measured values of Zeta potential for MAG-PANI were higher as compared to MAG indicating stabilization of particles in the presence of PANI. Relevant kinetic parameters for immobilized enzyme were determined from the Hanes plot. The apparent Km constant was 1.91 and 1.48 g L–1 for MAG-A and MAG-PANI-A, respectively, while Vm was 0.19 g L–1 min–1 for MAG and 0.32 g L–1 min–1 for MAG-PANI. The obtained values of Km indicated that modification of MAG by PANI enhanced kinetic properties of the immobilized enzyme. Moreover, the modification of MAG by PANI showed the increase in both pH and thermal stabilities of the immobilized enzyme. Studies of the operational activity of the immobilized enzyme on MAG-PANI have shown that 98.8% of starch was hydro-lyzed over 20.0 min. In the first cycle in the packed bed reactor operated in a recycling mode, but approximately five times longer period was required to hyd-rolyze 93.5 of starch in the fifth cycle. In the continuous packed bed reactor without recycling, the degree of starch hydrolysis was not changed significantly during 4 h and was 88.8±1.6%, whereas the half-life of the biocatalyst was 6.2 h. Although coating MAG particles with a polyaniline offers many advantages, the main disadvantage is possible appearance of residues of aniline monomers and dimmers. The potential toxicity of these residues requires precise composition analysis of the product of starch hydrolysis catalyzed by α-amylase adsorbed onto MAG-PANI. © 2018, Association of Chemists and Chemical Engineers of Serbia.

AB  - The electrochemical oxidation of the urea in near neutral pH is investigated on platinum electrode. It is shown that oxidation reaction is practically inhibited up to the potentials of ∼0.9 V. The same reaction is investigated onto electrochemically obtained titanium dioxide nanotubes modified by hematite using facile, low-cost successive ion layer adsorption and reaction (SILAR) method. It is shown that such system possesses electrocatalytic activity at very low potentials, and activity can be further improved by the illumination of the electrode in the photo-assisted reaction. The possible application of the photoactive anode is considered in the application of urea based water electrolysis and urea based fuel cell.

AB  - An environmentally friendly cell using polypyrrole-air regenerative cathode and zinc as anode is investigated in the 3% sodium chloride solution. The cell can operate in different charge and discharge mode. Polypyrrole can be reoxidized (doped) with chloride anions either by using dissolved oxygen or by an external power supply, e.g., small photovoltaic cell. In that way, after discharge, capacity retaining can be achieved by using seawater as the electrolyte. During low discharge rate, the delicate balance between solid state diffusion-controlled dedoping and chemical oxidation of polypyrrole produced by hydrogen peroxide is achieved, generating stable voltage plateau. The cell is proposed to operate as a power supply for different sensor devices in two modes. In the low discharge mode (10–20 mA g−1), it can be used for data acquisition, and at the fast discharge mode (up to 2 A g−1) for collecting data transmission.

AB  - The fast reaction of forced hydrolysis of iron(III) nitrate in hypochlorite solution at room temperature, leads to the formation of mainly hematite, α-Fe2O3. Successive ion adsorption and reaction (SILAR) is applied to decorate an electrochemically formed TiO2 nanotube electrode. The anodic photoelectrochemical behavior of pure TiO2-NT’s and modified electrodes are investigated in a sulfate containing solution at pH = 9.2. It is shown that such a modification leads to an increase of anodic photoactivity, as well as that at the same current density, the photoelectrochemical cell with a modified electrode operates at a voltage lower by 0.7 V. The band gap and flat band potentials are estimated, and the structure of the band gap and possible charge transfer reactions and mechanism are discussed.

AB  - The most common disinfectants for water treatment are based on chlorine and its compounds. Practically, water treatments with chlorine compounds have no alternative, since they provide, in comparison to other effective processes such as ozonization or ultraviolet irradiation, high residual disinfection capacity. Unfortunately, all of chlorine-based compounds for disinfection tend to degrade during storage, thus reducing the concentration of active chlorine. Apart from degradation, additional problems are transportation, storage and handling of such hazardous compounds. Nowadays, a lot of attention is paid to the development of electrochemical devices for in situ production of chlorine dioxide or sodium hypochlorite as efficient disinfectants for water treatment. The most important part of such a device is the electrochemical reactor. Electrochemical reactor uses external source of direct current in order to produce disinfectants in electrochemical reactions occurring at the electrodes. Construction of an electrochemical device for water treatment is based on evaluation of optimal conditions for electrochemical reactions during continues production of disinfectants. The aim of this study was to develop a low-cost electrochemical device for the production of disinfectant, active chlorine, at the place of its usage, based on newly developed technical solutions and newest commercial components. The projected electrochemical device was constructed and mounted, and its operation was investigated. Investigations involved both functionality of individual components and device in general. The major goal of these investigations was to achieve maximal efficiency in extreme condition of elevated room temperature and humidity with a novel device construction involving coaxial heat exchanger at the solution inlet. Room operation of the proposed device was investigated when relative humidity was set to 90% and the ambient temperature of 38°C. The obtained results in such extreme operation conditions reveled that it was possible to obtain required concentration of 0.85% of active chlorine with maximal temperature of outlet electrolyte of 35.3°C, which is within the limits of optimal temperatures.

Electrochemical synthesis was performed in 0.5 mol dm(-3) HCl and 0.2 mol dm(-3) pyrrole at constant current density of 2 mA cm(-2). Chronopotentiometric curves of polypyrrole enzyme electrode were recorded at current density of 42 nA cm(-2) for different glucose concentrations. The determined value of the apparent Michaelis-Menten constant was 0.045 mmol dm(-3) which is significantly lower than that of free enzyme indicating enhanced enzyme efficiency when it is immobilized into electroconducting polymer matrix.

AB  - The immobilization of α-amylase via adsorption on magnetic particles coated with polyaniline was studied. The support was characterized by field emission scanning electron microscopy (FESEM). The obtained magnetic particles were agglomerates of nanoparticles with sizes below 100 nm. The effects of various factors on immobilization, including time, the initial enzyme concentration, pH, and temperature, were examined. The optimum pH, temperature, and time for immobilization were established to be 7, 45°C and 75 min, respectively. The maximum amount of adsorbed α-amylase of 10/100 mg support was determined at the 5 mg/mL enzyme concentration. It appeared that α-amylase was stabilized in terms of pH and temperature by adsorption on magnetic particles coated with polyaniline. The good agreement of the equilibrium data with the Langmuir isotherm model confirmed the monolayer coverage of enzyme molecules on the surface of magnetic particles, and the maximum adsorption capacity was found to be 55.6/100 mg support at 25°C. The biocatalyst retained 55.5 ± 1.63% of its initial activity after nine cycles of reuse in starch hydrolysis at 60°C in a batch reactor. The immobilized enzyme also showed very good storage stability.

AB  - Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of prepared TiO2 nanoparticles and TiO2-PANI nanocomposite were determined by a transmission electron microscopy (TEM). The surface modification of TiO2 nanoparticles was confirmed by FTIR and UV–vis spectroscopy, while the morphology of PANI and TiO2-PANI nanocomposite was investigated by scanning electron microscopy (SEM). The influence of TiO2-PANI nanocomposite on glass transition temperature, dielectric and dynamic mechanical properties, thermooxidative stability, mechanical and anticorrosion properties of epoxy based nanocomposites was investigated and compared to the properties of epoxy/PANI nanocomposites. It has been observed that the glass transition temperature of epoxy resin increases after introduction of PANI and TiO2-PANI nanocomposite, as well as with increasing their content. Prepared nanocomposites exhibited higher value of dielectric constant than pure epoxy resin. Epoxy based coating containing TiO2-PANI nanocomposite showed lower dielectric loss, higher hardness and better anticorrosion properties than pure epoxy resin and epoxy/PANI nanocomposite.

AB  - The potential application of electrochemically formed copper sulfide as horseradish peroxidase mediator in the enzymatic biofuel cell and anthraquinone AV109 dye as a fuel is investigated. The open circuit voltage of 0.52 V and short circuit current of ∼3.6 µA/cm2 are obtained, with the maximum specific power of ∼1 µW/cm2. The influence of internal resistance of the cell is discussed. Decolorization is investigated under open circuit potentials, and under external load of 3.3 kΩ conditions. In both cases, 40% of decolorization is achieved, but are three times faster under external load conditions. Specific energy during decolorization in such cell is estimated to ∼5 mWh/m2. The possible mechanism of the power generation during decolorization of AV 109 dye is discussed.

AB  - Due to unique properties of intrinsically conducting polymers (ICP) such as: electrical conductivity, reversible electrochemistry, optical activity, biocompatibility, environmental and corrosion stability, they still represent a base for both theoretical and practical studies. The mentioned properties open up possibilities for practical application in the field of electrochemical systems for energy storage and conversion, sensors, biosensors, antistatic coatings, magnetic shielding, active corrosion protection etc. Bearing in mind that nanostructurization of materials lead to improvement of physical and chemical properties, there is a growing interest in the development of nanosized ICP. Nanosized ICP can be prepared by both chemical and electrochemical procedures. Although chemical synthesis is a common approach, there are also not a few studies of electrochemical synthesis of ICP. The aim of this paper is to review literature dedicated to electrochemical formation of nanostructured ICP with special attention dedicated to polyaniline and polypyrrole as the most popular ICPs.
AB  - Interesovanje za elektroprovodne polimere kako u teorijskom tako i praktičnom smislu utemeljeno je u jedinstvenim svojstvima ovih materijala, kao što su: kontrolisana električna provodljivost, reverzibilna oksidacija redukcija (dopovanje/dedopovanje), optička aktivnost, bio-kompatibilnost, korziona postojanost itd. Ova svojstva otvaraju mogućnosti praktične primene u oblasti elektrohemisjkih primarnih i sekundarnih izvora električne energije, elektrohemijskih kondenzatora, senzorima, biosenzorima, aktivnoj zaštiti od korozije. Imajući u vidu da nanostrukturizacija materijala dovodi do značajnog poboljšanja fizičkih i hemijskih svojstava materijala postoji veliko interesovanje za proučavanje nanostruktuirasnih elektroporvodnih polimera. Nanostruktuirani elektroprovodni polimeri mogu se dobiti hemijskim i elektrohemijskim postupcima sinteze. Iako je hemijska sinteza zastupljenija, u literaturi može se naći značajan broj radova posvećen elektrohemisjkom formiranju nanostruktuiranih elektroprovodnih polimera, pa je upravo i ovaj tekst posvećen toj probelmatici, u prvom redu elektrohemisjkom formiranju nanostruktura polianilina i polipirola kao najznačajnijih predstavnika elektroprovodnih polimera.

AB  - The potential characteristics of graphite felt electrodes, modified by iron oxide, for oxygen reduction are evaluated. Modification is carried out by Successive Ion Layer Adsorption and Reaction (SILAR) method, using a solution of ferric nitrate in methanol for the adsorption of ions, and a solution of sodium hypochlorite for reaction. The reaction activity of the oxygen reduction from the air, in sodium sulfate based solution varying the number of SILAR cycles, as well as the influence of pH is investigated. By comparing the activity with pure platinum, similar activity is obtained at pH = 9.2, as well as good electrode stability. Possible mechanism of the oxygen reduction on the graphite felt modified by iron oxide is discussed.
