Isotopic studies of the ammonia decomposition reaction mediated by sodium amide.


PMID 26271016

Abstract

We demonstrate that the ammonia decomposition reaction catalysed by sodium amide proceeds under a different mechanism to ammonia decomposition over transition metal catalysts. Isotopic variants of ammonia and sodium amide reveal a significant kinetic isotope effect in contrast to the nickel-catalysed reaction where there is no such effect. The bulk composition of the catalyst is also shown to affect the kinetics of the ammonia decomposition reaction.
