SrO-Bi2O3-Fe2O3-Based Composites: Synthesis and Electrophysical Properties

Resumo

New composite solid electrolytes formed in the SrO–Bi₂O₃–Fe₂O₃ system have been studied. The total electrical conductivity of the composites synthesized via the solid-phase method increases with an increase in the Fe2O₃ content, being of mixed ion-electronic nature. Dependence of the fraction of ionic conductivity on the composition has been established. The resulting materials have exhibited photocatalytic activity and are interesting as elements of electrochemical devices.
