AB  - TiO2 powder was synthesized by a forced hydrolysis process and used for the synthesis of Pt/TiO2 composite that is to be foreseen as an advanced electrode material. Pt was incorporated into the synthesized TiO2 from a Pt colloidal dispersion as a precursor prepared by a microwave- assisted polyol process. Physicochemical properties of TiO2 and TiO2- supported Pt were investigated by scanning electron microscopy, dynamic light scattering and X- ray spectroscopy and diffraction techniques. The properties of Pt/TiO2 composite are correlated to the basic voltammetric response of its thin-layer form. It was found that subsequent thermal treatment of synthesized TiO2, which caused crystallization into mainly rutile phase, is required for appropriate Pt incorporation. Although being appropriately loaded by Pt, and the voltammetric response is typical for Pt-based material, the voltammetry of Pt/TiO2 corresponded to much lower loadings.The possibility for Pt particles to be trapped inside TiO2 agglomerates is indicated. The catalyst usage from the synthesized Pt/TiO2 was found quite moderate due to this trapping.

AB  - Ruthenium oxide coating on titanium was prepared by the sol-gel procedure from well-defined colloidal oxide dispersions synthesized by the microwave (MW)-assisted hydrothermal route under defined temperature and pressure heating conditions. The dispersions were characterized by dynamic light scattering (DLS) measurements and scanning electron microscopy (SEM). The electrochemical properties were analyzed as capacitive performances gained by cyclic voltammetry and electrochemical impedance spectroscopy and as the electrocatalytic activity for oxygen evolution from acid solution. The obtained dispersions were polydisperse and contained regular particles and agglomerates of increasing surface energy and decreasing particle size as the MW-assisted heating conditions were intensified. Owing to these features of the precursor dispersions, the obtained coatings had considerably improved capacitive performances and good electrocatalytic activity for oxygen evolution at high overpotentials.

AB  - Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging regimes. An investigation of the responses to dynamic perturbations of typical representatives, noble metal oxides, carbonaceous materials and RuO2-impregnated carbon blacks, by electrochemical impedance spectroscopy (EIS) is presented. This presentation follows a brief description of supercapacitive behavior and origin of pseudo-capacitive response of noble metal oxides. For all the investigated materials, the electrical charging/discharging equivalent of the EIS response was found to obey the transmission line model envisaged as a so-called 'resistor/capacitor (RC) ladder'. The ladder features are correlated to material physicochemical properties, its composition and the composition of the electrolyte. Fitting of the EIS data of different supercapacitive materials to appropriate RC ladders enables in-depth profiling of the capacitance and pore resistance of their porous thin-layers and finally the complete revelation of capacitive energy storage issues. .

AB  - The electrochemical properties of a sol-gel-prepared IrO2-TiO2 coating on Ti were investigated from the standpoint of the charging/discharging behavior in 1.0A degrees mol dm(-3) H2SO4 and in 0.50A degrees mol dm(-3) NaCl, pH 2. The potential-dependent changes from low oxidation states of Ir, with low activity, to those of higher activity (enhanced pseudocapacitive performances) were analyzed at different charging/discharging rates by cyclic voltammetry and electrochemical impedance spectroscopy. The results showed the distribution of Ir oxidation states through the coating, with lower ones being placed largely in the internal, hardly accessible, parts of the coating. The transition to higher oxidation states appears as crucial for the full development of pseudocapacitive performances. This transition occurs much easier in the NaCl than in the H2SO4 solution, since the potentials of redox transitions of Ir are much closer due to lower hydrogen ion concentration in NaCl solution. As a consequence, a unique overall coating capacitance was registered in both solutions.

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.
AB  - U radu su ispitivane elektrohemijske karakteristike Ti0,6Ir0,4O2/Ti i Ti0,6Ru0,4O2/Ti anoda dobijenih sol-gel postupkom iz oksidnih solova sintetisanih forsiranom hidrolizom odgovarajućih hlorida metala. Voltametrijske karakteristike u rastvoru H2SO4 ukazuju na više izraženo pseudokapacitivno ponašanje Ti0,6Ir0,4O2/Ti elektrode koje je posledica površinskih redoks prelaza u čvrstom stanju uz učešće protona. 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. Ti0,6Ir0,4O2/Ti anoda je elektrokatalitički aktivnija za reakciju izdvajanja kiseonika, dok su anode sličnih aktivnosti za reakciju izdvajanja hlora. Impedansne karakteristike formiranih anoda pokazuju da se Ti0,6Ru0,4O2/Ti elektroda ponaša slično kondenzatoru u širem opsegu potencijala nego što je to slučaj sa Ti0,6Ir0,4O2/Ti elektrodom, sa potpuno razvijenim pseudokapacitivnim svojstvima na potencijalima pozitivnijim od 0,60 VZKE. S druge strane, za Ti0,6Ir0,4O2/Ti elektrodu se uočava prelaz sa karakteristika sličnih otporniku na karakteristike slične kondenzatoru sa porastom potencijala elektrode.

abstract = "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., U radu su ispitivane elektrohemijske karakteristike Ti0,6Ir0,4O2/Ti i Ti0,6Ru0,4O2/Ti anoda dobijenih sol-gel postupkom iz oksidnih solova sintetisanih forsiranom hidrolizom odgovarajućih hlorida metala. Voltametrijske karakteristike u rastvoru H2SO4 ukazuju na više izraženo pseudokapacitivno ponašanje Ti0,6Ir0,4O2/Ti elektrode koje je posledica površinskih redoks prelaza u čvrstom stanju uz učešće protona. 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. Ti0,6Ir0,4O2/Ti anoda je elektrokatalitički aktivnija za reakciju izdvajanja kiseonika, dok su anode sličnih aktivnosti za reakciju izdvajanja hlora. Impedansne karakteristike formiranih anoda pokazuju da se Ti0,6Ru0,4O2/Ti elektroda ponaša slično kondenzatoru u širem opsegu potencijala nego što je to slučaj sa Ti0,6Ir0,4O2/Ti elektrodom, sa potpuno razvijenim pseudokapacitivnim svojstvima na potencijalima pozitivnijim od 0,60 VZKE. S druge strane, za Ti0,6Ir0,4O2/Ti elektrodu se uočava prelaz sa karakteristika sličnih otporniku na karakteristike slične kondenzatoru sa porastom potencijala elektrode.",

AB  - The photoelectrochemical properties of a sol-gel prepared titanium oxide coating applied onto a Ti substrate were investigated. The oxide coating was formed from an inorganic sol thermally treated in air at 350°C. The coating consisted of agglomerates of narrow size distribution around 100 nm. The photoelectrochemical characteristics were evaluated by investigating the changes in the open circuit potential, current transients and impedance characteristics of a Ti/TiO2 electrode upon illumination by UV light in H2SO4 solution and in the oxidation of benzyl alcohol. The electrode was found to be active for photoelectrochemical reactions in the investigated solutions.

AB  - The properties of activated titanium anodes, RuO2-TiO2/Ti and RuO2--TiO2-IrO2/Ti, prepared from oxide sols by the sol-gel procedure, are reviewed. RuO2 and TiO2 sols were synthesized by forced hydrolysis of the corresponding chlorides in acid medium. The morphology of the prepared sols was investigated by transmission electron microscopy. The chemical composition of the RuO2 sol was determined by X-ray diffraction and thermogravimetric analysis. The loss of electrocatalytic activity of a RuO2-TiO2/Ti anode during an accelerated stability test was investigated by examination of the changes in the electrochemical characteristics in the potential region of the chlorine and oxygen evolution reaction, as well as on the open circuit potential. These electrochemical characteristics were investigated by cyclic voltammetry, electrochemical impedance spectroscopy and polarization measurements. The changes in electrochemical characteristics of the anode prepared by the sol-gel procedure were compared to the changes registered for an anode prepared by the traditional thermal decomposition of metal chlorides. The comparison indicated that the main cause for the activity loss of the sol-gel prepared anode was the electrochemical dissolution of RuO2, while in the case of thermally prepared anode the loss was mainly caused by the formation of an insulating TiO2 layer in the coating/Ti substrate interphase. The results of an accelerated stability test on RuO2-TiO2/Ti and RuO2--TiO2-IrO2/Ti anodes showed that the ternary coating is considerably more stable than the binary one, which is the consequence of the greater stability of IrO2 in comparison to RuO2.

AB  - The characteristics of a ternary oxide coating, on titanium, which consisted of TiO2, RuO2 and IrO2 in the molar ratio 0.6:0.3:0.1, calculated on the metal atom, were investigated for potential application for cathodic protection in a seawater environment. The oxide coatings on titanium were prepared by the sol-gel procedure from a mixture of inorganic oxide sols, which were obtained by forced hydrolysis of metal chlorides. The morphology of the coating was examined by scanning electron microscopy. The electrochemical properties of activated titanium anodes were investigated by cyclic voltammetry and polarization measurements in a H2SO4- and NaCl-containing electrolyte, as well as in seawater sampled on the Adriatic coast in Tivat, Montenegro. The anode stability during operation in seawater was investigated by the galvanostatic accelerated corrosion stability test. The morphology and electrochemical characteristics of the ternary coating are compared to that of a sol-gel-prepared binary Ti0.6Ru0.4O2 coating. The activity of the ternary coating was similar to that of the binary Ti0.6Ru0.4O2 coating in the investigated solutions. However, the stability in seawater is found to be considerably greater for the ternary coating.
