A new layered perovskite oxyhydride BaYHO was synthesized via high pressure synthesis. Powder X-ray and neutron diffraction experiments revealed that in BaYHO the ordered H and O anions form [BaH] rock-salt layers wherein H conduction is allowed. The conductivity reached 0.1 mS cm at 350 °C, which is higher than that of isostructural BaScHO with anion-disordered [BaHO] layers.
通过高压合成法合成了一种新型层状钙钛矿氢氧化物BaYHO。粉末X射线和中子衍射实验表明，在BaYHO中，有序的H和O阴离子形成了[BaH]岩盐层，其中允许H传导。在350°C时，电导率达到0.1 mS/cm，高于具有阴离子无序[BaHO]层的同结构BaScHO。
