摘　　要：储氢密度高(19.6%)的氨硼烷(AB)是一种很有前途的化学储氢材料,室温下通过催化水解可释放3 mol当量的氢气。氨硼烷在水中放氢速率缓慢,需要开发高活性金属纳米催化剂来加速其水解制氢过程。本研究从氨硼烷结构中特殊的双氢键入手,总结了氨硼烷的合成、表征方法以及水解催化制氢的机理。综述了调节催化剂的物质的量比、改变纳米粒子结构以及增大催化剂比表面积对氨硼烷释氢性能的影响,并对氨硼烷的研究前景进行了展望。Ammonia borane(AB)is a promising chemical hydrogen storage material with high hydrogen storage density(19.6%),which can release three molar equivalents of hydrogen through catalytic hydrolysis at room temperature.However,AB releases hydrogen slowly in water,it is necessary to develop highly active metal nanocatalysts to accelerate the process of hydrolysis.This article provides an overview of the synthesis and characterization methods of ammonia borane,the mechanism of hydrolysis and catalytic hydrogen production using the unique dihydrogen key in the ammonia borane structure,and the various factors that affect the hydrogen release performance of AB.
