## Description

- description: Hexagonal perovskite, Ba7Nb4MoO20, Ba7Nb4-xMo1+xO20+(1/2)x (x = 0.1),
    Ba7Nb4-yWyMoO20+(1/2)y (y = 0.15), and Ba7Ta4-zMo1+zO20+(1/2)z (z = 0.3) have
    recently been reported to exhibit high oxide-ion and proton conductivity. These
    materials are of great interest in industrial applications such as solid oxide
    fuel cells (SOFCs) and proton ceramic fuel cells (PCFCs) and are known for their
    unusual structures. Although the structures of Ba7Nb4MoO20 and their related materials
    were primarily analyzed by assuming an even distribution of Mo and Nb at each
    M(= Mo/Nb) site, solid-state nuclear magnetic resonance (NMR) spectra have revealed
    that Mo and Nb are unevenly distributed in Ba7Nb4MoO20. As it is crucial to determine
    whether the contributions to oxide-ion and proton conduction are the same for
    Mo and Nb, we focused on the signal differences among these as-prepared materials.
