摘要：

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 degrees C), effective prevention of any unwanted gaseous products, such as ammonia, diborane, confirming a very high hydrogen release purity of >99%. The activation energy (E-a) of the first-step dehydrogenation of HBB is calculated to be 106.4 kJ/mol using Kissinger's method. According to the B-11 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.
