AB  - The influence of different hydroxides, applied to activate carbon black, on the electrochemical properties of activated carbon was investigated. The carbon material was prepared by hydrothermal treatment of sucrose and afterwards thermally activated using KOH, NaOH and LiOH. The electrochemical properties of the obtained samples were examined by cyclic voltammetry and electrochemical impedance spectroscopy and correlated to their physicochemical properties. All samples showed characteristic capacitor-like behaviour. The highest specific capacitance was obtained for the KOH-treated sample, while the increase in capacitance follows the sequence of the growth of ionic radius of a metal from an alkali which is used for activation. It was found that the dependence on the type of hydroxide is due to differences in the radii of a metal. The alkalies of larger radii of metal generated make pores wider and consequently the structure of a porous layer become more accessible to the charge transfer of capacitive response.
AB  - Испитиван је утицај различитих активирајућих хидроксида на електрохемијска својства активираних угљеничних материјала. Угљенични материјал је добијен хидротермалним третманом сахарозе, а потом активиран помоћу KOH, NaOH и LiOH. Електрохемијска својства добијених узорака испитивана су цикличном волтаметријом и спектроскопијом електрохемијске импеданције. Синтетизовани материјали показују капацитивна својства. Највећа специфична капацитивност добијена је за узорак третиран помоћу KOH, док капацитивност прати величину пречника јона метала из алкалије којом је активиран угљенични материјал.

AB  - The production of chlorine by electrochemical oxidation of chlorides (chlor–alkali technology, CAT) is nowadays one of the largest processes in industrial electrochemistry. The main products – chlorine and the corresponding hydroxide – are, besides sulfuric acid and ammonia, the most important industrial inorganic chemicals. The third product – hydrogen (as a by-product) – is very valuable from the standpoints of contemporary power sources (“hydrogen economy;” fuel cells) and different industrial synthesis (mostly organic). the tailoring of the synthesis of electrode materials at the nanolevel, in order to increase the catalyst efficiency and/or to reduce the catalyst consumption, is seen as a valuable future direction in the development of advanced materials in chlorine electrocatalysis.

AB  - Polarization characteristics of titanium anodes, coated by active RuO2-TiO2 binary oxide using sol-gel preparation procedure and chloride thermal decomposition, in oxygen evolution reaction during anode electrolytic degradation were investigated in HClO4 solution. The accelerated electrolytic degradation of oxide coating has been performed in 3 mass% NaCl, pH 2. The anode prepared by sol-gel procedure is of better polarization characteristics than the anode prepared by thermal decomposition, which makes the former more suitable for the application in cathodic protection of metallic and steel constructions exposed to the sea water corrosion attacks.
AB  - Polarizacione karakteristike titanskih anoda, aktiviranih RuO2-TiO2 prevlakom različitim postupcima, u reakciji izdvajanja kiseonika tokom elektrolitičke degradacije anode, ispitivane su u rastvoru HClO4. Ubrzana elektrolitička degradacija oksidne prevlake vršena je u 3 mas % rastvoru NaCl, pH 2. Utvrđeno je da anode aktivirane sol-gel postupkom imaju bolje polarizacione karakteristike od anoda dobijenih termičkom razgradnjom, odnosno pogodnija svojstva za potencijalnu primenu u katodnoj zaštiti metalnih i čeličnih konstrukcija izloženih korozivnom dejstvu morske vode.

AB  - In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case and on the surface of the coating in the other. The electrochemical behavior of these, with TiO2 enriched, anodes was compared with the behavior of anodes with regular RuO2–TiO2 coatings, which were subjected to an accelerated stability test. A high-frequency semicircle in the complex plane plot obtained by electrochemical impedance spectroscopy, for a regular RuO2–TiO2 coating corresponds to TiO2 enrichment in the coating as a consequence of anode corrosion. In the case of the coatings with additional TiO2 layers, a high-frequency semicircle was not observed. The additional TiO2 layers increase the coating overall resistance and influence the coating impedance behavior at low frequencies. Similar equivalent electrical circuits were used to analyze the impedance behavior of coatings having an additional TiO2 layer at different position within RuO2–TiO2 coating.

Elektrohemijsko ponašanje ovih upoređeno je sa ponašanjem anoda sa uobičajenom RuO2–TiO2 prevlakom, kao i sa onima koje su bile podvrgnute ubrzanom testu stabilnosti.

Dodati TiO2 slojevi povećavaju omsku otpornost prevlake i utiču na impedancijsko ponašanje pri niskim frekvencijama.

AB  - The influence of different parameters (forced hydrolysis duration in the preparation of sols, alcohol addition in the sol mixture for application, as well as sol/alcohol mixture ageing time) on the morphology and electrochemical properties of RuO2-TiO2 coatings obtained by the sol-gel procedure is presented. The oxide sols were sharacterized by spectroscopic and microscopic methods (X-ray diffraction, TEM, etc). The morphology of the obtained coatings was examined by scanning tunneling microscopy, while the electrochemical properties were investigated by cyclic voltammetry polarization measurements, electrochemical impedance spectroscopy and the accelerated stability test. The greatest real surface area was obtained for coatings with the smallest RuO2 particles and largest TiO2 particles. Alcohol addition caused enlargement of the oxide grains and, consequently, a decrease in the real surface area. The same effects of oxide grain size were registered on electrochemically active surface area. The electrocatalytic activity of the obtained anodes for the chlorine evolution reaction increased with growth of the TiO2 particles, but depended on the RuO2 particle size to a small degree. The corrosion stability of the anode coatings consisting of the smallest RuO2 particles and largest TiO2 particles whis the greatest in the electrolysis of a sodium-chloride solution.

AB  - Electrochemical properties of glassy carbon electrodes of two types were examined, one thermally treated at 1000°C (sample K) and another thermally treated at 2500° (sample G). Mechanically polished or electrochemically polarized electrodes were characterized in NaOH, HClO 4 and H 2 SO 4 solutions by cyclic voltammetry (cv) at different sweep rates in the potential range between the hydrogen and oxygen evolution. The activity of the electrodes depended on the properties of the glassy carbon examined, as determined by both the temperature of thermal treatment and the mechanical or electrochemical pretreatment of the sample. It was noticed that both types of electrodes, when polished exhibited an increase in the double layer charge upon increasing the pH value of the solution. The cv charges, for both types of samples, increase upon anodic polarization. The higher the potential of oxidation, the more pronounced is the increase in charge, particularly in acidic solution. The increase in charge amounts from below 1 mC cm -2 for polished glassy carbon up to few hundreds of mC cm -2 for surfaces anodically polarized in acidic solution. Analysis of the dependence of voltammetric charge, as well as morphological changes of the electrode surface, on the time of oxidation suggests the existence of three stages in the electrochemical activation process. The first one occurs only once at the beginning of the activation, while the other two repeat themselves, reflecting a periodical activation and deactivation process. These stages were discussed and ascribed to a surface layer oxidation, graphite oxide layer growth and mechanical destruction of the surface. Independent surface analysis by AES, XPS and STM confirms the results obtained by electrochemical methods.

AB  - The effect of formaldehyde on the oxidation of 2-propanol and vice versa on gold single crystal planes (100 and 111) was studied. An activating effect in the reaction of the simultaneous oxidation of 2-propanol and formaldehyde was obtained on a gold (100) plane. In the case of a gold (111) electrode, the activation effect was not obtained. It was concluded that the adsorption of formaldehyde on the electrode surface prevents the adsorption of poisoning species formed during the electro-oxidation of 2-propanol on the Au(100) plane, while this is not the case on the Au(111) plane. The different behavior is caused by the difference in the symmetry of the surface atoms of these two Au single crystal planes. .

Zaključeno je da prisustvo adsorbovanog formaldehida onemogućava adsorpciju čvrsto vezanih intermedijera formiranih tokom elektrooksidacije 2-propanola, koji se ponašaju kao otrovi za elektrodu, na ravni (100).

at elevated temperature. The Ti supported coatings were obtained by the sol–gel method using a sol mixture in which
the metal content was Ru(40%)–Ti(60%). The crystal structure of the solid phase of the sols and their mixtures was
examined by X-ray diffraction. The surface and morphology of the coatings were characterized by scanning electron
microscopy and scanning tunneling microscopy. Polarization measurements and cyclic voltammetry were used to
obtain information about the electrochemical properties of the obtained anodes. An accelerated corrosion test was
applied to quantify the anode stability for the chlorine evolution reaction. A stability comparison of the anodes shows
a considerably higher lifetime for sol–gel coated anodes than for those obtained by the usual thermal decomposition

AB  - Oxygen reduction reaction has been studied on Pt low index planes in 0.1 M and 85% H3PO4 using hanging meniscus rotating disc electrode technique. The first-order kinetics of O2 reduction reaction was found for all three surfaces in a four-electron process with the first electron transfer rate determining in both 0.1 M and 85% H2PO4 solutions. Catalytic activity for O2 reduction follows the sequence Pt (110)>Pt (100)>Pt (111). Structural dependence is predominantly determined by the adsorption of phosphoric acid anions, which is strongly structure-dependent on Pt surfaces.

AB  - Electrocatalytic oxide coatings with variable concentration profiles of RuO2 as the active component were obtained through a combination of separately applied layers of RuO2, TiO2, IrO2, RuO2 + TiO2 and RuO2 + IrO2 on titanium and glassy carbon substrates. The stability of the samples was examined by accelerated tests performed at high anodic current densities. Electrochemical techniques, cyclic voltammetry for assessing the charge associated with the coating, polarization measurements for assessing the electrocatalytic activity, and Auger electron spectroscopy to register surface composition of the coatings, were applied to follow changes due to the stability experiments. The stability and the charge depended strongly on the sequence of layers in the RuO2-TiO2 coating, with the samples having the RuO2 + TiO2 layer facing the electrolyte exhibiting the highest values for both properties. In contrast to this, the stability of the RuO2-IrO2 coatings, besides being lower than the stability of RuO2-TiO2 coatings, showed no dependence on the sequence of the applied layers. Much lower stability was exhibited by the coatings applied on glassy carbon rather than on titanium. A mechanism of the stability of the coatings based on the interaction of lower than four valency state titanium with higher than four valency ruthenium, proposed for single-crystal surfaces, is corroborated. Finally, during the thermal treatment a diffusion of titanium originating in the titanium substrate through the coating was established.

AB  - There have been several attempts to elucidate events occurring on platinum immersed into pure perchloric acid solutions, when submitted to high anodic polarisation. The polarisation curve was shown to exhibit two levels, the second one occurring passed a limiting current which appears to be due to adsorption phenomena. Speculations have been made concerning the possible reaction mechanism which postulated the existence of several species acting as intermediates or reaction products. It was the purpose of this work to use some new techniques for the investigation of those species as well as to extend the observations to the alkaline perchlorate solutions and to those containing chlorate ions.

It was the purpose of this work to use some new techniques for the investigation of those species as well as to extend the observations to the alkaline perchlorate solutions and to those containing chlorate ions.",
