【摘要】：肼硼烷(N_2H_4BH_3,HB)的含氢量高达15.4 wt%,易于制备,物理化学性质稳定,是一种极具潜力的化学储氢材料。肼硼烷可以通过热解、醇解和水解产氢。特别是,通过水解其硼烷基和选择性裂解肼基实现完全产氢后,其对应的N_2H_4BH_3-3H_2O系统的有效理论质量储氢容量达10 wt%,远高于已知的氢源系统NaBH_4-4H_2O(7.3 wt%),NH_3BH_3-4H_2O(5.9 wt%)和N_2H_4·H_2O(8.0 wt%)。合适的催化剂是促使肼硼烷完全产氢的关键。本文简要地介绍了肼硼烷的合成与表征,重点综述了温和条件下肼硼烷的硼烷基水解和肼基分解产氢所使用的催化体系及其催化性能,对肼硼烷完全产氢的机理进行分析,并对肼硼烷催化产氢的应用前景进行展望。
[Abstract]:The hydrogen content of N _ 2H _ 2H _ 2H _ 2H _ 2H _ 3H _ 3 HBs is as high as 15.4 wt. it is easy to be prepared, and its physicochemical properties are stable, so it is a potential chemical hydrogen storage material. Hydrazine boranes can be produced by pyrolysis, alcoholysis and hydrolysis. In particular, the theoretical hydrogen storage capacity of the corresponding N_2H_4BH_3-3H_2O system is up to 10 wts after the complete hydrogen production is achieved by hydrolysis of its borane group and selective pyrolysis hydrazine group, which is much higher than that of the known hydrogen source system, NaBH_4-4H_2O(7.3 WTX, NaBH_4-4H_2O(7.3, and N_2H_4 H_2O(8.0 WT. Appropriate catalyst is the key to complete hydrogen production of hydrazine borane. In this paper, the synthesis and characterization of hydrazine borane are briefly introduced. The catalytic systems and their catalytic properties for the hydrolysis of hydrazine borane and the hydrogen production by hydrazine decomposition under mild conditions are reviewed. The mechanism of complete hydrogen production of hydrazine borane is analyzed. The prospect of hydrogen production catalyzed by hydrazine borane is also prospected.
