摘要：

Two new hydrogen storage compounds,Na Zn（BH4）3·en and Na Zn（BH4）3·2en（en=ethylene diamine）are synthesized by a solution method.They can release 6.4 wt% and 6.3 wt% pure hydrogen below 200℃,respectively,demonstrating the potential to be used as hydrogen carriers.Additionally,their dehydrogenation products,thermodynamics and kinetics are well characterized and analyzed.Results shows that the stronger Zn-N interactions and the Hδ+–Hδ- interactions are significant for their stability below 100℃,relatively low decomposition temperatures and elimination of gas impurities.
