ELECTROCHEMICAL BEHAVIOR OF CaBaCo₂O₅±δ IN NEUTRAL AQUEOUS SOLUTION
Keywords:
cobalt mixed oxides, CaBaCo2O5±δ, Ca2 ions insertion, cyclic voltammetry, chrono- electrochemical methodsAbstract
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.
