The H(NH2BH2)nH oligomers are possible products from dehydrogenation of ammonia borane (NH3BH3) and ammonium borohydride (NH4BH4), which belong to a class of boron-nitrogen-hydrogen (BNHx) compounds that are promising materials for chemical hydrogen storage.

Amine Borane Based Hydrogen Carriers An Evaluation Essay

The dehydrogenation of chemical hydrogen itself can be accomplished either hydrolytically by reaction with water 1 or thermolytically by heating the compound, as with ammonia borane (NH 3 BH 3) 2 and alane (AlH 3). 3 Given their high hydrogen capacity, ammonia borane and amide and amine compounds and variants remain systems of interest. As in the case of complex hydrides, the reaction pathway.
