Abstract

Ammonia decomposition using N labelled ammonia was performed over a lithium imide catalyst with mass spectrometry. The results show that all the nitrogen is released from the bulk of the lithium imide catalyst during the ammonia decomposition reaction, but that the decomposition itself occurs at the catalyst surface; they also indicate that lithium imide decomposes ammonia and does not merely act as a promoter to transition metal catalysts.

摘要

使用含氮标记氨的氨分解反应在锂酰亚胺催化剂上通过质谱法进行。结果表明，在氨分解反应过程中，所有的氮都从锂酰亚胺催化剂的主体中释放出来，但分解本身发生在催化剂表面；这些结果还表明，锂酰亚胺可分解氨，而不仅仅是作为过渡金属催化剂的促进剂。
