In the recent years, polyborate anions have been considered as possible candidates for energy. In aqueous solutions, they have been studied as either hydrogen carriers or anodic fuels. In the solid state (as an alkali salt), they have been seen as solid electrolytes. Herein, we focus on sodium 1-oxa-nido-dodecaborate NaB11H12O, a novel possible candidate for the aforementioned applications. The compound is soluble in water, and its stability depends on pH: under acidic conditions, it readily hydrolyzes while liberating hydrogen, and under alkaline conditions, it is stable, which is a feature searched for an anodic fuel. Over bulk platinum, gold, or silver electrode, oxidation takes place. The best performance has been noticed for the silver electrode. In the solid state, NaB11H12O shows Na+ conductivity at a high temperature of up to 150 °C. All of these properties are presented in detail, and hereafter they are discussed while giving indications of what have to be developed to open up more realistic prospectives for NaB11H12O in energy.

评估1-Oxa-nido-十二硼酸钠NaB11H12O用于储能的潜力。

近年来,多硼酸根阴离子被认为是能量的可能候选物。在水溶液中,它们已被研究为氢载体或阳极燃料。在固态(作为碱金属盐)中,它们被视为固体电解质。在本文中,我们集中于1-氧杂-nido-十二硼酸钠NaB11H12O,一种适用于上述应用的新型候选物。该化合物可溶于水,其稳定性取决于pH值:在酸性条件下,它易于水解,同时释放出氢;在碱性条件下,它是稳定的,这是寻找阳极燃料的一个特征。在大量的铂,金或银电极上,会发生氧化。银电极具有最佳性能。在固态下,NaB11H12O在高达150°C的高温下显示Na +电导率。
