Abstract

Dodecaborates, i.e. the B12H12 containing species, are often observed as main intermediates in the hydrogen sorption cycle of metal borohydrides, hindering rehydrogenation. In the decomposition process of Y(BH4)3, yttrium octahydrotriborate, i.e. Y(B3H8)3, rather than the stable Y2(B12H12)3, is formed as the main intermediate.

摘要

十二硼烷，即含有B12H12的物质，通常作为金属硼氢化物吸氢循环中的主要中间体被观察到，阻碍了再氢化。在 Y(BH4)3 的分解过程中，形成的主要中间体是八硼酸三钇，即 Y(B3H8)3，而不是稳定的 Y2(B12H12)3。
