Abstract

LiH and Ti-doped Al react quantitatively with H(2) in Me(2)O solution to form LiAlH(4) under mild conditions. The solvent is easily vented along with excess H(2) on completion, leaving dry Ti-doped LiAlH(4); this releases approximately 7 wt % H(2) commencing at 80 degrees C with excellent kinetics.

摘要

氢化锂和钛掺杂的铝在温和条件下于二甲醚溶液中与氢气定量反应生成氢化铝锂。反应完成后，溶剂可随过量氢气轻松排出，留下干燥的钛掺杂氢化铝锂；该物质在80摄氏度时开始释放约7 wt%的氢气，动力学性能优异。
