  Article:   ELECTROCHEMICAL BEHAVIOR OF CaBaCo2O5±δ IN NEUTRAL AQUEOUS SOLUTION.

  Abstract:   This paper presents the effect of Y3+  substitution with Ca2+  ions on the electrochemical behavior of Y-112 perovskite in neutral aqueous solution during oxygen insertion/release. Perovskite electrochemical behavior was studied by cyclic voltammetry and chrono-electrochemical methods. In correlation with these techniques the compound morphology was determined by scanning electron microscopy (SEM). Based on obtained results the electrochemical reactions occurring at interface compound – electrolyte have been identified.

Keywords: cobalt mixed oxides, CaBaCo2O5±δ, Ca2+ ions insertion, cyclic voltammetry, chrono- electrochemical methods.
