我们报告了Ba-Li氢氧化物中Ba与K的异价部分取代,其表现出由结构相变引起的高H−电导率。通过15%K/Ba取代,相变温度降低了约50 °C,导致在较低温度下的高电导率。
We report aliovalent partial substitution of Ba with K in Ba–Li oxyhydride, which exhibits a high H− conductivity caused by structural phase transitions. The phase transition temperatures were decreased by approximately 50 °C via 15% K/Ba substitution, resulting in a high conductivity at lower temperatures.
