| 摘要 |
<p>The present invention provides a process for the preparation of Ti-doped alkali metal and/or alkaline-earth metal aluminium hydride, comprising intimately mixing: an alkali metal and/or alkaline-earth metal aluminium hydride, or at least one alkali metal hydride and/or alkaline-earth metal hydride, metallic aluminium and H2, with in the range of from 0.5 to 20 mol % of Ti(OCH3)4, based on the moles of Al in the prepared Ti-doped alkali metal and/or alkaline-earth metal aluminium hydride. The invention further relates to a Ti-doped alkali metal and/or alkaline-earth metal aluminium hydride, obtainable by a process according to the invention, a hydrogen storage material comprising a Ti-doped alkali metal and/or alkaline-earth metal aluminium hydride according the invention, a process for reversibly desorbing and/or absorbing hydrogen, the use of a Ti-doped alkali metal and/or alkaline-earth metal aluminium hydride according to invention to store hydrogen and the use of Ti(OCH3)4 as Ti-dopant for an alkali metal and/or alkaline-earth metal aluminium hydride.</p> |
