Abstract The new proton-conducting phases BaLaIn0.9M0.1O4.05 (M = Ti, Zr) with Ruddlesden-Popper structure were obtained. The substitution of In3+ ions by the Ti4+ and Zr4+ ions leads to the expansion of the ab plane due to the incorporation of the oxygen interstitials in the La–O rock-salt blocks. It was established that all investigated samples were capable for the water uptake from the gas phase due to the presence in the structure of La–O blocks. The degree of hydration increased with an increase in the size of the salt blocks. It was proved that doping led to the increase in the oxygen ionic conductivity due to the formation of interstitial oxygen. The conductivity values for doped sample BaLa0.9M0.1InO3.95 were higher than for undoped composition BaLaInO4 by ~1 order of magnitude. The new phases BaLaIn0.9M0.1O4.05 (M = Ti, Zr) demonstrate the predominant protonic conductivity at Т

具有 Ruddlesden-Popper 结构的新相 BaLaIn0.9M0.1O4.05 (M=Ti, Zr) 中的质子传输

摘要 获得了具有Ruddlesden-Popper结构的新型质子传导相BaLaIn0.9M0.1O4.05 (M = Ti, Zr)。由于在 La-O 岩盐块中掺入氧间隙，Ti4+ 和 Zr4+ 离子取代 In3+ 离子导致 ab 平面的扩展。由于 La-O 块结构中的存在，已确定所有研究的样品都能够从气相中吸收水。水化程度随着盐块尺寸的增加而增加。事实证明，由于形成间隙氧，掺杂导致氧离子电导率增加。掺杂样品 BaLa0.9M0.1InO3.95 的电导率值比未掺杂组合物 BaLaInO4 高约 1 个数量级。新相 BaLaIn0.9M0.1O4.05 (M = Ti,
