不同结构催化剂催化氨硼烷产氢的研究现状

Research Status of Hydrogen Production from Ammonia Borane Catalyzed by Catalysts with Different Structures

随着化石能源的消耗,新型清洁能源的开发迫在眉睫。氢能源因其燃烧性能好,且产物为水、无污染而备受关注。目前,氨硼烷(AB,NH3BH3)作为一种固体储氢材料已经引起了广泛的研究兴趣。氨硼烷分子量较轻,理论储氢密度高达19.6 wt%,其水解产氢反应条件温和、速率可控,且气体产物仅为氢气,因此氨硼烷作为一种质轻、无毒、环保的固体储氢材料具有非常好的应用前景。本文主要分析了目前几种常见的不同结构催化剂对于AB水解产氢效果的影响,最后对AB催化产氢研究方向进行了展望,以期为提高AB催化产氢效率提供借鉴。

With the consumption of fossil energy,the development of new clean energy is extremely urgent.Hydrogen energy has attracted much attention because of its good combustion performance,and its product is water without pollution.Nowadays,ammonia borane(AB,NH3BH3)as a solid hydrogen storage material has attracted extensive research interest.The molecular weight of ammonia borane is relatively light,and the theoretical hydrogen storage density is as high as 19.6 wt%.The reaction conditions for hydrolytic hydrogen production are mild,the reaction rate is controllable,and the gas product is only hydrogen.Therefore,ammonia borane has a very good application prospect as a light,non-toxic and environmentally friendly solid hydrogen storage material.This paper mainly analyzes the influence of several common catalysts with different structures on the hydrogen production effect of AB hydrolysis.Finally,the research direction of AB catalytic hydrogen generation is prospected,in order to provide a reference for improving the efficiency of AB catalytic hydrogen generation.
