Hydrazine bisborane as a promising material for chemical hydrogen storage

Journal Article


Abstract


  • A kind of promising hydrogen storage material-hydrazine bisborane (N2H4(BH3)2, HBB) is

    synthesized by a typical chemical method. HBB exhibits relatively low dehydrogenation

    temperature (around 100 C), effective prevention of any unwanted gaseous products, such

    as ammonia, diborane, confirming a very high hydrogen release purity of >99%. The

    activation energy (Ea) of the first-step dehydrogenation of HBB is calculated to be 106.4 kJ/

    mol using Kissinger’s method. According to the 11B NMR and FT-IR results, the thermal

    decomposition of HBB was determined to produce [HBN2BH]2 dimers, in which the coordination

    environment of B atoms located in the formation of HBN2.
