分别采用NiCl2和CoCl2对二硼肼(HBB)的脱氢反应进行了强化,其中NiCl2的强化效果较好。通过加入2.0亿摩尔。%NiCl2时,HBB的脱氢性能得到显著改善,脱氢过程中NH3的杂质被完全抑制,纯氢的生成量超过13.0wt.%。用基辛格方法计算出HbB和Ni掺杂HbB的第一步表观活化能分别为143.2和60.7kJ·−-1。差示扫描量热法(DSC)结果表明,NiCl2的加入并没有改变HBB脱氢的热变。根据理论分析和文献综述,HBB脱氢性能的改善可能归因于Ni2+与HBB的NH2基团中的电负性N的固态相互作用。
NiCl2and CoCl2were adopted to enhance the dehydrogenation of hydrazine bisborane (HBB), respectively, of which NiCl2showed better performance. By adding 2.0 mol. % NiCl2, the dehydrogenation property of HBB was significantly improved, for example, the impurity of NH3during the dehydrogenation of HBB was totally suppressed with more than 13.0 wt. % of pure hydrogen evolved. By Kissinger method, the apparent activation energies of the first step for HBB and Ni-doped HBB were calculated to be 143.2 and 60.7 kJ mol−1, respectively. DSC result showed that the addition of NiCl2did not change the enthalpy change of HBB dehydrogenation. Based on theoretical analysis and literature review, the improved dehydrogenation property of HBB was potentially ascribed to the solid state interaction of Ni2+with the electronegative N in the NH2group of HBB.
