AB  - The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcan® XC-72 R with solid phase of RuO xHy sol, were investigated by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. The oxide sols of different ageing times, prepared by forced hydrolysis of RuCl 3, were used for composite preparation. The prepared composites show considerably higher capacitance values in acid electrolyte if compared to carbon black support. Microscopic investigations show that the extent of impregnation and the composite surface appearance depend on ageing time. The composite capacitance increases with ageing time of oxide sol. A gradual decrease in capacitance of thermally untreated composite with charging/discharging cycles was registered, which appears to be related to the extent of impregnation, too. Electrochemical impedance spectroscopy measurements indicate an in-depth capacitance distribution through the composite layer. It was found that Nafion® layer, used to ensure the adhesion of the composite layer to the current collector, influenced the composite impedance behavior, especially on the oxide-rich parts of the composite surface.

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  - U radu je ispitivan uticaj dodavanja etanola odnosno izopropanola u disperznu sredinu smeše solova TiO2 i RuO2 na morfologiju i elektrohemijske osobine aktiviranih titanskih anoda dobijenih sol-gel postupkom. Osobine ovako dobijenih anoda su poređene kako međusobno tako i sa osobinama anoda dobijenih termičkim postupkom iz hlorida rutenijuma i titana. Morfologija anodnih prevlaka ispitivana je skenirajućom tunelskom mikroskopijom, a elektrohemijsko ponašanje cikličnom voltametrijom i polarizacionim merenjima. Stabilnost anoda u paralelnim reakcijama izdvajanja kiseonika i hlora ispitivana je ubrzanim testom stabilnosti. Uočeno je da morfologija, elektrokatalitička aktivnost i stabilnost dobijenih anoda zavisi od vrste dodatog alkohola.
