Аннотация: A kinetic model of oxygen reduction at an inert electrode in a carbonate melt has been proposed. Combined with the thermodynamic calculations of the chemical equilibria in the carbonate melts and with the diffusivity values taken from the literature, the model was used to simulate kinetics of oxygen reduction reaction at a gold electrode in the Li2CO3 / K2CO3 (62 / 38 mol %) molten electrolyte under 0.33 О2 + 0.67 СО2 atmosphere at 923 K for the case of coulostatic pulse perturbation. The simulation has shown that the partial exchange current of the View the MathML source reduction step makes the largest contribution to the overall exchange current, and neutralization of the oxide ion by CO2 controls the rate of the overall electrode process. The total exchange current per one-electron electrode reaction was estimated as 83 mA/cm2. The simulation has demonstrated satisfactory agreement with the experiment.

Аннотация: The work related to the study of the initial stages of the silicon electrodeposition on the glassy carbon electrode in molten KF-KCl-K2SiF6 was performed. The silicon nucleation and growth process was investigated using cyclic voltammetry, chronoamperometry, and scanning electron microscopy. It was shown that the electrocrystallization process occurs by the instantaneous nucleation with diffusion-controlled growth under the studied conditions. The Scharifker-Hills theoretical model was used to calculate the nucleation density and the diffusion coefficient of depositing ions.

ОКСИД ХРОМА -- АНОД -- ЭЛЕКТРОЛИЗ -- РАСТВОРЕНИЕ
Аннотация: In order to fabricate oxide-metallic composites with the composition 25.3NiO-41.2Fe2O3-13.5Cr2O3-20.0Cu (wt %), the temperature and duration of sintering (1350°C, 30 min) that ensure the formation of the solid solution of chromium oxide in nickel ferrite have been determined. This material is tested as an anode for the electrolysis of the low-temperature solution with the composition 12.0NaF-36.8KF-51.2AlF3 (wt %), which was saturated with Al2O3 (t = 800°C). The amount of gaseous oxygen evolved on the anode was measured. It is shown that the main reaction on an anode at current density i = 0.015–1.0 A cm−2 is the oxidation of oxygen-containing anions from a melt with the formation of gaseous O2 and a substantial increase in the oxidation rate of the composite anode is observed at i > 1.0 A cm−2. The voltage across the electrolyzer (4.5 ± 0.5 V) and the anodic potential (2.43 ± 0.2 relative to the Al reference electrode) during a prolonged experiment (for 89 h, i = 0.4 A cm−2) indicate a stable and acceptable electrical conductivity of the material, while the dissolution rate, which was calculated by the weight loss (0.6 kg/yr) and volume loss (0.7 cm/yr), satisfy the requirements to inert anodes.

Аннотация: Снижение рабочей температуры твердооксидных топливных элементов (ТОТЭ) является основным направлением их развития, для реализации которого необходимо осуществить подбор материалов электролита и электродов. Высокопроводящий электролит на основе галлата лантана считается перспективным материалом для создания среднетемпературных ТОТЭ. В ходе данной работы были исследованы электрохимические характеристики катода La0.6Sr0.4Fe0.8Co0.2O3 - в контакте с электролитом La0.88Sr0.12Ga0.82Mg0.18О2.85 в зависимости от температуры формирования электрода. Определено, что при оптимальных температурах припекания 1200–1250°С поляризационное сопротивление катода при 800°С составляет около 0.08 Ом см2, что сопоставимо с лучшими мировыми достижениями.

Аннотация: This work presents the electrochemical study of NdCl3 solutions in fused low-melting LiCl–KCl–CsCl eutectic and individual CsCl at the temperature range 573–943 K using inert molybdenum electrodes. The mechanism of the electrochemical reduction was investigated by transient electrochemical technique. It has been shown that Nd3+ ions are reduced to metallic neodymium through two consecutive steps: Nd3+ + ē → Nd2+ and Nd2+ + 2ē → Nd0. The chemical stability of Nd2+ ions in fused chloride melts was studied at different temperatures. It was determined that the compound NdCl2 is not stable in molten solutions at high temperatures (above 810–840 K). The results of a study of the Nd3+/Nd2+ couple redox potentials vs. Cl−/Cl2 reference electrode at a wide temperature range in molten LiCl–KCl–CsCl eutectic was carried out by direct potentiometric method. Apparent standard redox potentials of the couple were determined. Basic thermodynamic properties of the reaction NdCl2(l) + ½Cl2(g) ⇔ NdCl3(l) were calculated

Аннотация: This work presents the electrochemical study of TmCl3 solutions in NaCl–2CsCl eutectic at the temperature range 823–973 K using inert and reactive electrodes, i.e. Mo and Al, respectively. On an inert electrode, Tm3+ ions are reduced to metallic thulium through two consecutive steps: Tm3+ + e− → Tm2+ and Tm2+ + 2e− → Tm. The electroreduction of Tm3+ to Tm2+ ions was found to be reversible at low scan rates being controlled by the rate of the mass transfer and irreversible at high scan range (>0.1 V s−1) being controlled by the rate of charge transfer. The diffusion coefficient of [TmCl6]3− complex ions was determined at different temperatures. Arrhenius law was verified by plotting the variation of the logarithm of the diffusion coefficient vs. reverse temperature. The apparent standard potential of the soluble-soluble redox system Tm3+/Tm2+ was obtained by cyclic voltammetry. The electrode reactions of Tm3+ solutions at an Al electrode were also investigated. The results showed that for the extraction of thulium from molten chlorides, the use of a reactive electrode made of aluminum leading to Al–Tm alloys seems to be a pertinent route

ЭЛЕКТРОЛИЗ АЛЮМИНИЯ -- ТЕМПЕРАТУРА -- АНОД -- ПОЛЯРИЗАЦИЯ
Аннотация: The influence of the [KF]/[AlF3] ratio (1.1–1.5 mol mol−1), the Al2O3 concentration (1–5 wt.%) and the temperature (973–1073 K) on the overpotential of the anode process for a glassy carbon electrode in a KF–AlF3–Al2O3 melt under stationary and non-stationary conditions was studied by galvanostatic polarisation and chronopotentiometry. A theoretical (mathematical) description of the two-step electrode process at the carbon anode in KF–AlF3–Al2O3 melts under stationary and non-stationary conditions is suggested. The charge of the electric double-layer, the formation of an intermediate COads adsorption product at the anode surface, the limitations of the current transfer, which include the charge transfer through the electrode/electrolyte interface, and the diffusion and chemical interaction of the electroactive ions in the melt near the anode surface were taken onto account. Alterations of the basic parameters of the process were monitored and analysed. Estimates of anode process kinetics parameters (e.g., exchange current densities and the degree of the anode surface coverage by the intermediate product COads) for different experimental conditions were made by a comparison of the modelled and experimental polarisation curves. The electrochemical desorption of the intermediate product COads from the anode surface (the second step) was shown to be relatively slower than the charge transfer process (the first step). In addition, slow chemical reactions at current densities of 0.1–1 A cm−2 can occur prior to the electrode process.

ПОТЕНЦИОМЕТРИЧЕСКОЕ ТИТРОВАНИЕ -- РАСТВОРИМОСТЬ -- СТАНДАРТНЫЙ ПОТЕНЦИАЛ -- NaCl–2CsCl
Аннотация: The physical and chemical properties of chromium chlorides have been studied in fused NaCl–2CsCl eutectic at the temperature range 843–1008 K using an electrochemical cell containing a platinum-oxygen electrode with solid electrolyte membrane, which was used as pO2? indicator electrode. The concentration of oxygen ions in the solution was modifying by dropping the calculated amount of BaO. Titration of Cr3+ chlorocomplex by O2? ions demonstrated the precipitation of CrOCl and Cr2O3. The solubility constants of these compounds were calculated. E–pO2? and three-dimensional E–pO2?–T type diagrams, which summarized the properties of chromium species in the melt, were determined.??
