AB  - Electrochemical double-layer capacitor (also called supercapacitor) is an electrochemical energy storage device with a high power density, which could be used in application such as pulse power devices or electric vehicles. The paper describes construction of an electrochemical double-layer capacitor that consists of two electrodes immersed in an electrolyte with a separator between them. One electrode consists of a current collector in contact with the active material, while the other one is a counter electrode. Commercially available activated carbon (AC) material, Composite RuO2 + AC and natural copper sulfides are used as the active electrode material. Characterization has been performed by an electrochemical system fully developed at Technical Faculty in Bor. The system is based on a PC P4, a commercially available ADDA converter and an external interface for analog signal processing. The software platform is LabVIEW 8.2 package and application software is adapted to investigations of the systems containing high capacitances.

AB  - The results of an investigation of two samples of commercial multi-walled carbon nanotubes and a sample of carbon black, in the raw and activated state, were presented in the lecture. The activation of the carbon materials led to the formation of an abundance of oxygen-containing functional groups on the surface, an increased electrochemically active surface area, an enhanced charge storage ability and a promotion of the electron-transfer kinetics. It was presented that the morphology of the carbon nanotubes is important for the electrochemical properties, because nanotubes with a higher proportion of edge and defect sites showed faster electron transfer and pseudocapacitive redox kinetics. Modification of oxidized nanotubes by ethylenediamine and wrapping by poly(diallyldimethylammonium chloride) led to a decrease in the electrochemically active surface area and to reduced electrontransfer kinetics. Pt nanoparticles prepared by the microwave-assisted polyol method were deposited at the investigated carbon materials. A much higher efficiency of Pt deposition was observed on the modified CNTs than on the activated CNTs. The activity of the synthesized catalyst toward electrochemical oxygen reduction was almost the same as the activity of the commercial Pt/XC-72 catalyst.
AB  - U okviru predavanja su prikazani rezultati ispitivanja dve vrste komercijalnih višeslojnih ugljeničnih nanocevi i uzorka ugljeničnog praha razvijene površine pre i nakon aktivacije hemijskom oksidacijom. Oksidacija uzoraka dovodi do izraženog formiranja kiseoničnih grupa na površini ugljeničnih materijala, povećanja elektrohemijski aktivne površine kao i do ubrzanja prenosa naelektrisanja. Pokazano je da morfologija ugljeničnih nanocevi ima značajan uticaj na njihove elektrohemijske karakteristike. Uzorak sa većim udelom ivica i defekata pokazao je bržu kinetiku prenosa naelektrisanja i veću pseudokapacitivnost. Modifikovanje oksidovanih nanocevi etilendiaminom i polimerom poli(dialildimetilamonijum-hloridom) dovodi do smanjenja aktivne površine i do sporijeg prenosa naelektrisanja. Nanočestice platine, sintetisane u rastvoru etilenglikola u mikrotalasnoj pećnici, nanete su na ispitivane ugljenične materijale. Količina nanete Pt je mnogo veća na modifikovanim nego na oksidovanim nanocevima. Aktivnost sintetisanih uzoraka za elektrohemijsku redukciju kiseonika je upoređena sa aktivnošću komercijalnog katalizatora Pt/XC-72 za istu reakciju i pokazalo se da su njihove specifične aktivnosti približno jednake.

AB  - Hydrous ruthenium oxide/carbon black nanocomposites were prepared by impregnation of the carbon blacks by differently aged inorganic RuO2 sols, i.e. of different particle size. Commercial Black Pearls 2000 (R) (BP) and Vulcan (R) XC-72 R (XC) carbon blacks were used. Capacitive properties of BP/RuO2 and XC/RuO2 composites were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in H2SO4 solution. Capacitance values and capacitance distribution through the composite porous layer were found different if high- (BP) and low- (XC) surface-area carbons are used as supports. The aging time (particle size) of Ru oxide sol as well as the concentration of the oxide solid phase in the impregnating medium influenced the capacitive performance of prepared composites. While the capacitance of BP-supported oxide decreases with the aging time, the capacitive ability of XC-supported oxide is promoted with increasing oxide particle size. The increase in concentration of the oxide solid phase in the impregnating medium caused an improvement of charging/discharging characteristics due to pronounced pseudocapacitance contribution of the increasing amount of inserted oxide. The effects of these variables in the impregnation process on the energy storage capabilities of prepared nanocomposites are envisaged as a result of intrinsic way of population of the pores of carbon material by hydrous Ru oxide particle.

AB  - Electrochemical properties of sol-gel processed Ti(0.6)Ir(0.4)O(2) and Ti(0.6)Ru(0.3)Ir(0.1)O(2) coatings on titanium substrate were investigated using cyclic voltammetry, polarization measurements and electrochemical impedance spectroscopy and compared to the properties of Ti(0.6)Ru(0.4)O(2) coating. The role of iridium oxide in the improvement of the electrocatalytic, capacitive and stability properties of titanium anodes activated by a RuO(2)-TiO(2) coating is discussed. The oxide sols were prepared by forced hydrolysis of the metal chlorides. The characterization by dynamic light scattering and X-ray diffraction showed that polydisperse oxide sols were obtained with the particles tending to form agglomerates. The presence of IrO(2) causes a suppression of the X-ray diffraction peaks of TiO(2) and RuO(2) in the sol-gel prepared Ti(0.6)Ir(0.4)O(2) and Ti(0.6)Ru(0.3)Ir(0.1)O(2) coatings. The IrO(2)-containing coatings had an enhanced charge storage ability and activity for the oxygen evolution reaction (OER) in comparison to Ti(0.6)Ru(0.4)O(2) coating. The voltammogram of the Ti(0.6)Ir(0.4)O(2)/Ti electrode showed well-resolved peaks related to Ir redox transitions, which are responsible for the enhanced charge storage ability of IrO(2)-containing coatings. Redox transitions of Ir were also registered in the high-frequency domain of the ac impedance spectra of the coatings as a semicircle with characteristics insensitive to the electrolyte composition and to the electrode potential prior to OER. However, the semicircle characteristics were different for the two IrO(2)-containing coatings, as well as at potentials outside the OER in comparison to those at which the OER occurs.

AB  - The electrochemical characteristics of Ti0.6Ir0.4O2/Ti and Ti0.6Ru0.4O2/Ti anodes prepared by the sol-gel procedure from the corresponding oxide sols, obtained by force hydrolysis of the corresponding metal chlorides, were compared. The voltammetric properties in H2SO4 solution indicate that Ti0.6Ir0.4O2/Ti has more pronounced pseudocapacitive characteristics, caused by proton-assisted, solid state surface redox transitions of the oxide. At potentials negative to 0.0 VSCE, this electrode is of poor conductivity and activity, while the voltammetric behavior of the Ti0.6Ru0.4O2/Ti electrode is governed by proton injection/ejection into the oxide structure. The Ti0.6Ir0.4O2/Ti electrode had a higher electrocatalytical activity for oxygen evolution, while the investigated anodes were of similar activity for chlorine evolution. The potential dependence of the impedance characteristics showed that the Ti0.6Ru0.4O2/ /Ti electrode behaved like a capacitor over a wider potential range than the Ti0.6Ir0.4O2/Ti electrode, with fully-developed pseudocapacitive properties at potentials positive to 0.60 VSCE. However, the impedance characteristics of the Ti0.6Ir0.4O2/Ti electrode changed with increasing potential from resistor-like to capacitor-like behavior.

Na potencijalima negativnijim od 0,0 VZKE ova elektroda pokazuje slabu provodnost i aktivnost, dok voltametrijskim ponašanjem Ti0,6Ru0,4O2/Ti elektrode dominira prodor protona u strukturu oksida.

AB  - The changes in capacitive behavior of C/H(x)RuO(y) composite material prepared by impregnating the Vulcan (R) XC 72R carbon black with oxide sols of different particle size are investigated as the electrolyte penetrates through the thin layer of the Nafion (R)-covered composite. The techniques of cyclic voltammetry and electrochemical impedance spectroscopy are used. Results of the investigation reveal the influence of potential cycling and the exposure time to the electrolyte on registered capacitive characteristics of composite. The cycling in a wide potential range causes the decrease in energy storage ability which depends on oxide particle size. Impedance measurements, however, show that the ability initially decreases and subsequently increases during exposure to the electrolyte as the consequence of the presence of Nafion (R) top-layer. Due to wettability and resistance issues, Nafion (R) top-layer can affect the pseudo-capacitive characteristics, and the energy storage ability of the composite consequently decreases.

AB  - The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the WC powder employed for the investigation was a single-phase material consisting of crystallites/spherical particles of average size of about 50 nm, which were agglomerated into much larger particles. Cyclic voltammetry showed that the WC underwent electrochemical oxidation, producing tungstate species. In the case of the mixed Pt + WC powders, the tungstate species were deposited on the Pt as a thin film of hydrous tungsten oxide. Enhanced hydrogen intercalation in the hydrous tungsten oxide was observed and it was proposed to be promoted in mixed powders by the presence of hydrogen adatoms on bare Pt sites. The determination of Pt surface area in the Pt + WC layer by stripping of underpotentially deposited Cu revealed that the entire Pt surface was accessible for underpotential deposition of Cu. Investigation of the electrochemical oxidation of methanol and formic acid on Pt + WC and pure Pt layers did not indicate electrocatalytic promotion due to the presence of WC.

AB  - Electrochemical properties and porous-structure-dependent capacitive ability of commercial carbon blacks, Black Pearls 2000® (BP) and Vulcan® XC 72R (XC), were investigated in H2SO4 solution by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The capacitance in-depth profile is correlated to microscopic appearance of carbon blacks in the form of a thin layer applied over Au substrate from water suspensions of BP and XC. The capacitance calculated from voltammetric charge was found to depend on the sweep rate, due to porosity of investigated materials. Impedance (EIS) characteristics upon frequency-dependent charge/discharge process indicate transmission line electric behavior of BP and XC. Capacitance and resistance values obtained by simulations of EIS data, enabled estimation of capacitance and resistance profile throughout carbon black porous electrodes. Capacitance of BP carbon layer increases going from the outer surface towards the bulk of the layer. External capacitance originates from capacitive characteristics of the macroscopic surface consisting of relatively large agglomerates, while internal capacitance originates from "inner" surface of micro-porous agglomerates. Contrary to BP, opposite distribution of the total capacitance to external and internal part was found for XC, caused by its loose structure and considerably lower real surface area in comparison to BP. The XC morphology makes additionally the pseudocapacitive contribution of surface functionalities more pronounced, which indirectly shifts also the "internal" double-layer capacitive response to higher frequencies through the effect of increased wettability of the layer. Thus, the capacitance of XC surface directly exposed to the electrolyte is larger than that of the inner one, which makes it a "fully-utilized" capacitor, while increased capacitive performance of BP emerges only at very low frequencies of charging/discharging process.

The capacitive properties of these materials were correlated to their composition, the preparation conditions of the oxides and coatings, the properties of the carbon support and to the composition of the electrolyte. The results of the electrochemical test methods, cyclic voltammetry and electrochemical impedance spectroscopy, were employed to resolve the possible physical structures of the mentioned porous materials, which are governed by the controlled conditions of the preparation of the oxide by the sol-gel process.

AB  - Electroactive oxide coatings on titanium, known in industrial chlorine production as dimensionally stable anodes (DSA), are of limited service life owing to the dissolution of active oxide, but also due to low corrosion stability of titanium, at high anodic potentials and elevated temperatures. In order to improve the anode stability, ternary carbide, Ti3SiC2, could be a promising material for the coating support, since chemical corrosion stability of Ti3SiC2 is significantly higher if compared to Ti. In this work, the possibility of the sol-gel preparation of RuO2-TiO2 coating on Ti3SiC2 is investigated and comparison of the basic characteristics of sol-gel processed oxide coating, Ru0.5Ti0.5O2, applied onto Ti3SiC2 and Ti, is reported. Microscopic investigation of the coating surface showed that considerably less cracked coating is formed onto the Ti3SiC2 support. Slightly higher voltammetric currents are registered for Ti3SiC2-supported coating in H2SO4 and NaCl solution. The activity for chlorine evolution is higher, while the currents of oxygen evolution reaction are lower for Ru0.5Ti0.5O2/Ti3SiC 2 anode in comparison to Ru0.5Ti0.5O2/Ti anode. Even though these preliminary results on the basic electrochemical properties of Ru0.5Ti0.5O2/Ti3SiC 2 anode and chemical stability of Ti3SiC2 are promising, the accelerated stability test in NaCl solution showed that coated Ti3SiC2 is not anodically stable and lasts considerably shorter than Ru0.5Ti0.5O2/Ti anode prepared and tested under the same conditions.

AB  - The capacitive properties of titanium electrodes with an active porous RuO2 coating were investigated in H2SO4 and NaCl solution by cyclic voltammetry and electrochemical impedance spectroscopy. Electrodes with two different masses of coating (thin and thick coating) were prepared from an ink suspension of the oxide synthesized by hydrolysis of ruthenium-ethoxide in ethanolic solution. The capacitive characteristics were found to be dependent on the coating mass and the electrolyte composition. It was shown that the impedance data of the prepared electrodes, registered at the open circuit potential, can be interpreted by a transmission line model of the equivalent electrical circuit. In this interpretation, the number of parallel branches containing resistor and capacitor in series is different for thin and thick coatings and in different electrolytes. More branches were required to describe the impedance behavior of the thick coating and to simulate the impedance data in NaCl solution. Simulation of the impedance data with the transmission line model of the equivalent circuit was also used to analyze the distribution of capacitance throughout the porous coating. The simulation indicated a more pronounced contribution of the capacitance of the outer coating layer to the total coating capacitance in the case of the proton-rich electrolyte. On the other hand, the presence of chloride ions in the electrolyte promoted a charging process at the inner coating surface, which is hardly accessible to the electrolyte.

Simulation of the impedance data with the transmission line model of the equivalent circuit was also used to analyze the distribution of capacitance throughout the porous coating. The simulation indicated a more pronounced contribution of the capacitance of the outer coating layer to the total coating capacitance in the case of the proton-rich electrolyte. On the other hand, the presence of chloride ions in the electrolyte promoted a charging process at the inner coating surface, which is hardly accessible to the electrolyte.",
