Effect of Ni-alloys on thermal decomposition of ammonia borane

• Three different nickel alloys is synthesized and applied as catalysts for NH3BH3 thermolysis.
• Effect of the synthesized catalysts are analyzed using TG–DTA–MS, XRD and FTIR spectroscopy.
• ZrNi and FeNi alloys lead to decrease in the unwanted gaseous by product release.

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 ∼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.
