High oxide-ion conductivity through the interstitial oxygen site in Ba7Nb4MoO20-based hexagonal perovskite related oxides

Oxide-ion conductors are important in various applications for clean energy. Here, authors report high oxide-ion conductivity of hexagonal perovskite-related oxide Ba7Nb3.9Mo1.1O20.05, which is ascribed to the interstitialcy diffusion and low activation energy for oxide-ion conductivity.
