| 简介 |
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 A1 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. |
