Exploration of hydride conductor

在本项目中，我们成功地合成了不含过渡金属的新型含氧化合物，其具有K2NiF4型结构的有序氢离子。氧杂环化合物在1500 ℃以上表现出氢离子电导率，且电导率随空位和间隙氢离子的引入而增大。此外，通过阳离子取代控制氢化物含量和晶格排列的合成方法的建立，为氧杂环化合物基新材料的开发提供了指导。

In this project, we successfully synthesized transition-metal-free novel oxyhydridesthat has the ordered hydride ions in the K2NiF4-type structure. The oxyhydridesexhibited the hydride ion conductivity over 1500C, and conductivity value increasewith the introducing vacancies and interstitial hydride ions, Furthermore, theestablishment of synthesis method for the controlling hydride contents andarrangement in the lattice by the cation-substitution showed a guideline for thedevelopment of new materials based on oxyhydrides.
