2-以2-氨基咪唑半硫酸盐((Im-NH 2)2SO 4)和硼氢化钠为原料,采用简单的球磨法合成了氨基咪唑硼氢化物(Im-NH 2BH 4)。该化合物具有8.1重量%的理论氢容量。它的设计基于使用大共轭阳离子Im-NH 2+使BH 4 −不稳定并通过平衡它们的数量来最大化质子-质子氢相互作用的策略。热脱氢分析表明,在低于320 °C时,它可以释放约3.2wt%的氢(包括Na 2SO 4)而没有气态杂质。分解过程有三个脱氢步骤,起始脱氢温度为50.5 °C。这些结果表明,上述策略是有效的。讨论了该化合物的脱氢过程,提出在320 °C下的产物为C_3N_3H_3BH。
2-Aminoimidazole borohydride (Im-NH2BH4) is synthesized via the reaction between 2-aminoimidazole hemisulfate ((Im-NH2)2SO4) and sodium borohydride by a simple ball milling method. This compound holds theoretical hydrogen capacity of 8.1 wt%. It is designed based on the strategy of destabilizating BH4− using a large conjugated cation, Im-NH2+ and maximizing the protonic-hydridic hydrogen interaction by balancing their numbers. Thermal dehydrogenation analyses demonstrate that it can release about 3.2 wt% hydrogen (Na2SO4 included) without gaseous impurities below 320 °C. The decomposition process has three exothermal steps and the onset dehydrogenation temperature is 50.5 °C. These results indicate that the above strategy is effective. The dehydrogenation process of this compound is discussed and the product at 320 °C is proposed to be C3N3H3BH.
