Understanding transition metal, oxygen and proton local order in proton conducting oxides

DOI

Proton conducting materials have received widespread attention in recent years, due to their rich potential in the areas of energy related research, sensors and membranes. Here, we continue our studies into the scandium doped barium titanate system in order to understand the proton conduction pathway in the cubic and hexagonal structure variants. Total scattering measurements are required on representative systems (x=0.2 and x=0.7 in BaScxTi1-xO3-delta) to probe local metal, oxide and proton ordering in the host and hydrated samples. We have also been able to synthesise a metastable cubic form of the x=0.2 material, which will allow direct comparison of the two structure types with identical protonation state. A fundamental study of this kind is key for future candidate material identification and development.
