| 摘 要： | Ce6-xHoxMoO15-δ(0.0≤x≤1.2) was synthesized by modified sol-gel method and characterized by diffe-rential X-ray diffraction(XRD), Raman, and X-ray photoelectron spectroscopy(XPS) methods. The oxide ionic con-ductivity of the samples was investigated by AC impedance spectroscopy. It shows that all the samples are single phase with a cubic fluorite structure. The solid solution Ce6-xHoxMoO15-δ(x=0.6) was detected to be the best con-ducting phase with the highest conductivity(σt=1.05×10-2 S/cm) at 800 ℃ and the lowest activation energy(Ea=1.09eV). These properties suggest that this kind of material has a potential application in intermediate-low temperature solid oxide fuel cells.
