摘要

A series of Nd/Mg co-doped ceria electrolytes, Ce_(0.8)Nd_(0.2−)x_(Mg)x_(O2−δ)(x = 0, 0.05, 0.10 and 0.15), werernsynthesised through a facile solgel method. The structure and electrical properties were characterisedrnby X-ray diffraction, scanning electron microscopy and AC impedance spectroscopy. An appropriaternelemental ratio of Nd/Mg in the co-doped experiment was found to be essential in improving thernelectrical performance of the ceria-based electrolytes. The optimum grain-boundary conductivityrn(2.28 × 10~(-2) S cm−1) and total conductivity (2.68 × 10~(-3) S cm~(-1)) were obtained at the doping 10 at.%rnNd and 10 at.% Mg.
