Vibrational properties of Barium Indate-Zirconate Perovskite Oxyhydride
Perovskite type oxyhydrides, ABO3-xHx are a novel class of hydride-ion (H-) conducting materials that may find diverse applications in the fields of catalysis, topochemical synthesis, and electrochemistry, but fundamental questions surrounding the mechanism of hydride-ion conductivity remain to be answered. In previous QENS experiments on BaTiO3-xHx we observed either long-range diffusion or localized motions of hydride-ions depending on the concentration of oxygen vacancies, highlighting that a key element for a robust understanding of hydride-ion dynamics in perovskite materials is a solid knowledge of the local coordination environment around the hydride-ions. With this proposal we want to investigate the local coordination environment around the hydride-ions in the very novel pervoskite oxyhydride BaZr0.5In0.5O2.25H0.5. Because the vibrational frequencies and intensities of hydride-ion modes are very sensitive to the surrounding species of hydride-ions, they are a very powerful probe of the local structure of BaZr0.5In0.5O2.25H0.5. We propose therefore to perform a one-day inelastic neutron scattering experiment at base temperature with the spectrometer IN1-LAGRANGE.
