Effect of Ni-alloys on thermal decomposition of ammonia borane

The principal disadvantage of thermal decomposition of ammonia borane is release of borazine during generation of hydrogen gas. In the current work, ZrNi, FeNi and CuNi alloys have been synthesized and used as additives to decrease the amount of borazine release. It was observed that ZrNi was most efficient resulting in similar to 22% decrease in the borazine release. The effect of the additives in decreasing the borazine release was observed to be in the order of ZrNi > FeNi > CuNi. (C) 2015 Elsevier B.V. All rights reserved.
