Abstract：La2Mo2O9-based oxide-ion conductors have attracted more and more attention since the high ionic conductivity was reported in 2000 by Lacorre et al. in this kind of material. In this paper the recent investigation on the novel La2Mo2O9-based oxide-ion conductors is reviewed. It is focused on the structure and phase transition, oxide-ion conductivity, mechanism of oxygen vacancy diffusion, chemical stability and thermal expansion coefficient in the pure and doped La2Mo2O9 samples. It is pointed out that the La2Mo2O9-based oxide-ion conductors could be possibly applied in the fields such as solid oxide fuel cells, oxygen sensors and oxygen permeable membranes.
