Lithium aluminum hydride

Lithium aluminum hydride (LiAlH4) is a promising compound for hydrogen storage, with a high gravimetric and volumetric hydrogen density and a low decomposition temperature. Similar to other metastable hydrides, LiAlH4 does not form by direct hydrogenation at reasonable hydrogen pressures; therefore, there is considerable interest in developing new routes to regenerate the material from the dehydrogenated products LiH and Al. It can also be used as a reducing agent in the preparation of reduced graphene oxide (rGO).
It is used as a powerful reducing agent inorganic synthesis. Except for olefinic doublebonds, almost all organic functional groupsare reduced by lithium aluminum hydride. It is used extensivelyin pharmaceutical synthesis and in catalytichydrogenation.
