AB  - Ceria coating is formed on Al from the ceria sol prepared exclusively by forced hydrolysis of Ce(NO3)(4), in order to test their ability to protect Al from corrosion. The characterization of sol-gel-processed ceria coating and coating/Al assembly brings new issues on Al corrosion and protection caused by unique properties of the sol-gel coating. The corrosion behaviour of bare Al and Al/CeO2 is investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to NaCl aqueous solution. The morphology and composition of the samples are examined by scanning electron microscopy and energy dispersive spectroscopy. EIS data showed greater corrosion resistance of CeO2-coated aluminium in comparison to bare Al at long exposure times. CeO2 coating does not hinder completely the corrosion processes on Al. The Al beneath CeO2 coating is subjected to intrinsic formation of a uniform protective coating/Al interphase, cross-linked by AlO(OH) fibre-like structures. They appear created by corrosive medium from the coating reversely gelled by NaCl solution. As the fibre network is created during exposure, Al becomes better protected than by spontaneous formation of porous passive layer of Al(OH)(3) on bare aluminium. Sol-gel ceria coatings thus improve corrosion resistance of aluminium during prolonged exposure to corrosive medium.

AB  - CeO2 coatings were formed on the aluminum after Al surface preparation, by dripping the ceria sol, pre­viously prepared by forced hydrolysis of Ce(NO3)4. The anticorrosive properties of ceria coatings were investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to 0.03% NaCl. The morphology of the coa­tings was examined by the scanning electron microscopy (SEM). EIS data indicated considerably larger corrosion resistance of CeO2-coated aluminum than for bare Al. The corrosion processes on Al below CeO2 coating are sub­jected to more pronounced diffusion limitations in com­parison to the processes below passive aluminum oxide film, as the consequence of the formation of highly com­pact protective coating. The results show that the deposi­tion of ceria coatings is an effective way to improve corro­sion resistance for aluminum.

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.

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.

AB  - The adsorption mechanisms of Pb2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge, pHpzc, is 7.4 ± 0.1 for natural sepiolite and 6.9 ± 0.1 for partially acid-activated sepiolite. The shift of the pHpzc of sepiolites toward lower pH values in solutions of Pb2+ and Cd2+ ions indicates that specific adsorption of these cations on natural and acid-activated sepiolites occurred, which was more pronounced for Pb2+ ions than for Cd2+ ions. There was no shift of the pHpzc in solution containing Sr2+ ions, suggesting that specific adsorption of this cation did not occur. The affinity for ion exchange with the Mg2+ ions from the sepiolite structure was the highest for Pb2+ ions, then Cd2+, whereas the affinity for Sr2+ ions was negligible. The adsorption isotherms suggest that the sequence of the efficiency of the sepiolites adsorption is Pb2+ > Cd2+ > Sr2+. The retention of Pb2+ and Cd2+ ions by sepiolite occurs dominantly by specific adsorption and exchange of Mg2+ ions from the sepiolite structure. The concentration in the external outer sphere of the Stern layer by electrostatic forces is the dominant mechanism for the retention of Sr2+ ions on the surface of sepiolites. Despite increases in the surface areas upon acid activation, improvements in the adsorption were not observed, as a result of the decreasing number of Mg-OH groups, as main centers for specific adsorption, and the number of Mg2+ ions available for ion exchange with Pb2+, Cd2+ and Sr2+ ions. The removal of Mg-OH groups from the sepiolite also resulted in a decrease in the point of zero charge and an increase of the relative surface acidity, from 2.6 ± 0.1 for the natural to 6.4 ± 0.1 for the acid-activated sepiolite.

The concentration in the external outer sphere of the Stern layer by electrostatic forces is the dominant mechanism for the retention of Sr2+ ions on the surface of sepiolites. Despite increases in the surface areas upon acid activation, improvements in the adsorption were not observed, as a result of the decreasing number of Mg-OH groups, as main centers for specific adsorption, and the number of Mg2+ ions available for ion exchange with Pb2+, Cd2+ and Sr2+ ions. The removal of Mg-OH groups from the sepiolite also resulted in a decrease in the point of zero charge and an increase of the relative surface acidity, from 2.6 ± 0.1 for the natural to 6.4 ± 0.1 for the acid-activated sepiolite.",

AB  - Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in an ethanolic solution (alkoxide route). The morphology of prepared oxide was examined by scanning electron microscopy. The electrochemical properties of the prepared Ti/RuO2 anodes, involving their cyclic voltammetric behavior in H2SO4 and NaCl solutions, activity in the chlorine and oxygen evolution reaction, impedance behavior in H2SO4, and stability during electrolysis in dilute chloride solutions, were investigated. The performances of the anodes are compared to those of a Ti/RuO2 anode prepared by the sol-gel procedure from an oxide sol obtained by the forced hydrolysis of ruthenium chloride in acid solution. The anodes prepared via the alkoxide route showed a higher capacitance and activity for the chlorine evolution reaction than the anode prepared by the inorganic sol-gel procedure. The results of the stability test showed that the utilization of the coating active material is better when the anodes were prepared via the alkoxide route than via the inorganic sol-gel procedure, particularly for anodes with a smaller mass of coating. The different rates of loss of activity indicate a degradation mechanism for the anodes prepared via the alkoxide route in which electrochemical dissolution of RuO2 from the coating surface prevails over the growth of an insulating TiO2 layer in the coating/Ti substrate interphase. The effect of RuO2 dissolution from the coating surface increases with increasing coating mass.

AB  - The deactivation process that leads to the end of titanium supported RuO2-TiO2 coating service life, for anodes prepared from RuO2 and TiO2 sols, as well as by the conventional thermal decomposition of RuCl3 and TiCl3, was investigated. The loss of electrocatalytic activity was registered by an accelerated stability test in 0.50 mol dm-3 NaCl electrolyte, while the changes in the electrochemical properties were monitored during the stability test by cyclic voltammetry, polarization measurements and electrochemical impedance spectroscopy in 1.0 mol dm-3 HClO 4 and in 0.50 mol dm-3 NaCl. The changes in anode behavior suggest that the essential cause for the deactivation of the anode prepared by the sol-gel procedure is the formation of an insulating TiO 2-rich layer at the coating surface due to the continuous dissolution of the Ru active species. However, the growth of the insulating TiO2 layer in the coating/Ti substrate interphase mainly causes deactivation of the thermally prepared anode. The deactivation mechanism appeared to be the consequence of the different morphology of the coatings prepared by two different procedures.

AB  - The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcano (R) XC-72 R with solid phase of RuOxHy 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 RuCl3, 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 (R) 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  - Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl methacrylate)-co-(ethylene glycol dimethacrylate)], poly(GMA-co-EGDMA), and copolymer modified with ethylene diamine, EDA, poly(GMA-co-EGDMA)-en, in the temperature range 333-363 K. Two poly(GMA-co-EGDMA) samples with different porosity parameters were synthesized by suspension copolymerization and modified using a ring-opening reaction of the pendant epoxy groups with EDA. The specific surface areas of the initial and modified copolymer samples were determined by the BET method from low temperature nitro- gen adsorption isotherms (77 K). The adsorption isotherms determined from chromatographic peaks of adsorbates were analyzed using the BET theoretical model and used for estimation of the surface area, isosteric heat of adsorption and the adsorption energy distribution on the surface of the initial and modified copolymer samples. It was observed that the adsorbate nature and the properties of the solid surface of the initial and modified copolymer governed the uptake of adsorbate by the copolymer. The deviations observed for the Sa values obtained by the BET method from the low temperature nitrogen adsorption isotherms and hexane was attributed not only to the difference in molecule size, but also to the specific polymer-adsorbate interactions. The isosteric heat of adsorption approached a constant value with increasing adsorbate loading. A large variation in the shapes of the q(st)-alpha curves resulted from strong acid-base interactions, as well as dissolution phenomena. Of the four studied adsorbates, chloroform was shown to have the greatest affinity towards the surface of the investigated polymer samples.

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  - Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) was synthesized by suspension copolymerization and modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine (EDA). Inverse gas chromatography (IGC) at infinite dilution was applied to determine the thermodynamic interactions of PGME and modified copolymer, PGME-en. The specific surface areas of the initial and modified copolymer samples were determined by the BET method, from low-temperature nitrogen adsorption isotherms. The specific retention volumes, Vg, of 10 organic compounds of different chemical nature and polarity (nonpolar, donor, or acceptor) were determined in the temperature range 333-413 K. The weight fraction activity coefficients of test sorbates, ohm(infinity)(1), and Flory-Huggins interaction parameters, chi(infinity)(12), were calculated and discussed in terms of interactions of sorbates with PGME and PGME-en. Also, the partial molar free energy, Delta G(1)(S), partial molar heat of mixing, Delta H-1(infinity), sorption molar free energy, Delta G(1)(S), sorption enthalpy Delta H-1(S), and sorption entropy, Delta S-S(1), were calculated. Glass transitions in PGME and PGME-en, determined from IGC data, were observed in the temperature range 373-393 K and 363-373 K, respectively.

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.

AB  - Preparation of RuOxHy/carbon black nanocomposite material was performed by the impregnation method starting from RuOxHy sol as a precursor. Black Pearls 2000® (BP) and Vulcan® XC-72 R (XC) were used as supporting materials. Samples of the composite were calcined in nitrogen atmosphere at temperatures from 130 to 450 °C. Chemical and structural characterization of the precursor and the composites was performed by using energy-dispersive X-ray fluorescence spectroscopy (EDXRFS), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). These techniques showed that the oxide impregnated into carbon support is hydrous and amorphous. The amorphous structure is maintained if the composite is calcined up to 300 °C, while the low-intensity peak at 2θ position that corresponds to the most intensive peak of the rutile structure was registered at 450 °C. The capacitance of the composite was determined using cyclic voltammetry. It was found that the capacitance is dependent on calcination temperature and surface area of the carbon black support. The highest specific capacitance of about 700 F g−1 of composite was registered for RuOxHy supported on BP and calcined at 300 °C while four times lower values was obtained for RuOxHy supported on XC. The capacitance measurements indicated that XC-supported RuOxHy composite is highly porous while BP-supported one is more compact.

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.

Osobine ovako dobijenih anoda su poređene kako međusobno tako i sa osobinama anoda dobijenih termičkim postupkom iz hlorida rutenijuma i titana.

AB  - TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis
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
method.
