Ionic conductivity in the novel complex oxide Ba0.95La1.05InO4.025 with Ruddlesden-Popper structure
High oxygen-ion and proton conductivity is an important property for energy materials, especially for those to be used in solid oxide fuel cells and electrolyzes. The Ruddlesden-Popper complex oxides are a prospective class of oxygen-ion conducting electrolytes. Well-known oxygen-ion conductors with the classic perovskite ABO3 structure have already been successfully doped using the donor-doping method. However, results on the application of this donor-doping method to Ruddlesden-Popper complex oxides are not so extensive. In this paper, novel complex oxide Ba0.95La1.05InO4.025 with a Ruddlesden-Popper structure has been synthesized and investigated for the first time. The oxygen-ion conductivity values for the new donor doped (La3+ → Ba2+) complex oxide Ba0.95La1.05InO4.025 are about 0.5 orders of magnitude higher than those for the undoped BaLaInO4 composition. The oxygen-ion transport numbers of the new composition Ba0.95La1.05InO4.025 reach approximately 90% at 300°C.
期刊介绍：
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
