Novel proton-conducting layered perovskite based on BaLaInO4 with two different cations in B-sublattice: Synthesis, hydration, ionic (O2?, H?) conductivity

The present study focused on the novel material with significantly improved properties for the application in the area of clean energy. The new complex oxide BaLaIn0.5Y0.5O4 with layered perovskite structure was obtained for the first time. It was proved that the introduction of Y3 thorn ions in the perovskite layer of BaLaInO4 leads i) to the rise of the oxygenionic conductivity due to the increase in mobility of oxygen ions as a result of the expand of the cell volume and ii) to the enhancement of protonic conductivity due to the increase in the proton concentration and mobility. The sample BaLaIn0.5Y0.5O4 is nearly
