AB  - The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the electrocatalytic activity for the chlorine evolution reaction (CER) of RuO2-TiO2/Ti electrode obtained by sol-gel procedure was investigated. The electrochemically active surface area was examined by cyclic voltammetry, while the analysis of the activity for the CER was performed by polarization measurements. The stability of the obtained anode coatings was also checked by an accelerated stability test. The anode properties depend on the number of C atoms in the alcohol molecule, as well as on the elapsed time between the preparation of the sols/alcohol mixture and its application onto the titanium support. The addition of alcohol increased the activity of the anodes for the CER, compared to those prepared without the addition, but their stability was smaller.
AB  - U radu je ispitivan uticaj metanola, etanola, 1-propanola i 2-propanola, dodatih u disperznu sredinu RuO2-TiO2 smeše solova, na elektrohemijski aktivnu površinu i elektrokatalitičku aktivnost za reakciju izdvajanja hlora (RIH) RuO2-TiO2/Ti elektroda dobijenih sol-gel postupkom. Elektrohemijski aktivna površina ispitivana je metodom ciklične voltametrije, dok je aktivnost za RIH ispitivana polarizacionim merenjima. Takođe je i ubrzanim testom stabilnosti ispitivana postojanost dobijenih oksidnih prevlaka. Utvrđeno je da osobine dobijenih anoda zavise od broja ugljenikovih atoma u molekulu dodatog alkohola i vremena proteklog od pripreme smeše alkohola i solova do nanošenja smeše na titanski nosač. Uočeno je da dodatak alkohola prouzrokuje povećanje aktivnosti anoda za RIH u odnosu na anode dobijene bez dodavanja alkohola. Istovremeno, anode dobijene dodavanjem alkohola su manje stabilne od anoda dobijenih bez dodavanja alkohola.

AB  - The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium anodes was investigated. The properties of the obtained anodes were compared to those obtained by the thermal decomposition of appropriate chloride salts. The morphology of the anode coatings was examined by scanning tunneling microscopy. The electrochemical behaviour was investigated by cyclic voltammetry and by polarization measurements. An accelerated stability test was used for the examination of the stability of the anodes under simultaneous oxygen and chlorine evolution reaction. A dependence of the anode stability on the type of added alcohol is indicated.

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  - Auger depth profiling was used to determine the local film thickness of a thin anodic oxide grown on a polycrystalline Ti substrate. The oxide thickness was studied as a function of substrate crystallography and final growth voltage. These results were related to local photocurrent measurements obtained using photoelectrochemical microscopy. Variations in the film thickness are too small to account for the non-uniform photocurrent response. The non-uniform photoresponse is instead attributed to variations in the defect density of the oxide

AB  - The (110) and the (100) surfaces of RuO2 show well defined LEED patterns. The surface lattice dimensions agree within 5% with the values predicted from X-ray diffraction. Both surfaces undergo a series of reversible surface reconstructions which result in well defined LEED patterns. These states come about from the loss of surface oxygen and each oxygen and each state is characterized by a well defined O Ru ratio. The final state is an overlayer of Ru metal. Furthermore, nearly equal concentrations of RuO3 are observed on all of the surfaces regardless of the structure which is present. This suggests that RuO3 plays a significant role in the stability of RuO2 surfaces.

AB  - Thin electrochemically grown oxide films on polycrystalline titanium substrates were examined by photoelectrochemical and electron diffraction techniques. Photoelectrochemical microscopy, based on illumination by a focused laser beam, was used to measure the local photoresponse of the oxide films. For oxide films grown slowly (1 nm/h)if, by ramping the electrode potential at 0.1 mV/s, the oxide photoresponse was found to map the grain structure of the underlying substrate. As the oxide growth rate was increased the photoresponse became more homogeneous and the average photocurrent decreased. The photoresponse heterogeneities were associated with variations in the structure of the oxide film. Electron diffraction studies showed that for slowly grown films, an ordered oxide structure was present with a preferential growth direction of [110] occurring on some substrate grains. As the oxide growth rate was increased the film structure became more homogeneous and the average oxide crystalline size decreased. The decrease in oxide crystallinity with increase in oxide growth rate was also observed in photospectroscopy measurements as a loss of the 3.7 eV direct bandgap. For all oxide films studied here, rutile was the only identifiable phase.

The data obtained have shown that the surface is enriched with Ir and also that the bulk composition is likely to be inhomogenous. The surface composition estimated on the basis of the voltammetric curves has been found to agree excellently with the results of ex situ surface analysis. Finally, the samples have been found to "absorb" protons from the solution through a mechanism which does not interfere with the estimation of the electrochemically active surface area on the basis of the voltammetric charge.

Thus, OH- ions in strongly alkaline solutions reveal its strong affinity to water by dissolving its protective oxide film. The metal establishes a very negative electrode potential, undergoing violent corrosion resulting in the evolution of hydrogen and the formation of aluminate ions.

AB  - Two types of anodic oxidation of aluminum have been recognized in the past: a) oxidation requiring a steady increase of voltage drop across the interface up to a few hundred volts in order to overcome the resistance of increasingly thick compact oxide layer and maintain a steady oxidation current, and b) a porous oxide layer forming oxidation resulting in layers of significant thickness, rather regular structure and with good adsorbing qualities (representing the basis of decorative anodization processes). The third type of oxidation is recognized, following seemingly normal anodic dissolution kinetics. This type of dissolution has been obtained in chloride, chlorate, and perchlorate solution and in some other electrolytes. In this third type, it has been found recently, however, that a careful elimination of pseudo-ohmic overpotential leads to an unusual type of polarization behavior, whereby after reaching some current density range, the polarization of the aluminum-electrolyte interface alone, decreases with increasing current density in an approximately linear. It is the purpose of this short communication to report in more detail about this phenomenon which is tantamount to the appearance of negative equivalent resistance at the surface.

AB  - The use of dimensionally stable titanium anodes activated with Pt, Ir or ruthenium oxide for electrolytic chlorate production has been investigated. Simultaneous measurements were made of the amount of noble metal at the surface and of electrode activity, as functions of time of electrolysis at constant current and temperature. After more than 400 days of operation, an electrode with 7 g m−2 of surface of noble metals exhibits good polarization characteristics as well as freedom from corrosion of the coating.
