000902059 520__ $$aInnovations in material science are the key element for solving technological challenges. Various energy and environmental applications require designing materials with tailored compositions, microstructures and specific target-oriented performance. Y and Mn co-substituted BaZrO3, e.g. BaZr0.85Y0.15Mn0.05O3-δ (BZYM5), has previously attracted attention as a membrane material for H2 separation from gas mixture due to its mixed proton-electron conductivity leading to appreciable levels of H2-flux at elevated temperatures and its good thermo-chemical stability under reducing environments. In the present work, we developed ceramic materials within the BaZr0.8Y0.2-xMnxO3-δ series, where x =0.02, 0.05, 0.10, and systematically studied their functional properties in dependence of the Y-to-Mn ratio, including thermal behaviour, hydration and electrical properties. In addition to that, near edge X-ray absorption fine structure spectra (NEXAFS) in the vicinity of O K-edge and Mn L2,3-edges was carried out for selected BZYM specimens to collect information on oxidation states and surrounding symmetry of Mn atoms in surface- and bulk- sensitive modes. Finally, we studied proton diffusion in hydrated BZYM samples using quasi-elastic neutron scattering (QENS). Two distinct dynamic processes were observed at temperatures above 300 °C: one faster more localized process and another slower long-range diffusion process. The long-range diffusion has clear characteristics of jump-diffusion. We will present a model for atomic scale proton diffusion in these materials, and we will further discuss how Mn doping influences the proton diffusion in these materials.
