Abstract

Nano-sized samarium doped ceria (SDC) material was synthesized through a sol-gel method in order to improve the intermediate-temperature performance of solid electrolyte for automobile oxygen sensor. The ionic conductive behavior of the electrolyte was analyzed on the basis of electrochemical impedance spectroscopy (EIS) test, and the interaction of working temperature, defect microstructure and ionic conductivity was investigated. Accordingly, the SDC displayed an ionic conductivity of 0.029 S cm-1 at 750 . It was suggested that the nano-crystalline could shorten the transfer distance of the charge carriers. Furthermore, the structural change of the polycrystal boundaries with the temperature was a key factor which promoted the oxygen ionic conductivity.
