Application
氨气是合成各种含氮无机化合物和有机中间体的一种常用试剂或反应物。它可直接用于气相反应或鼓泡通过反应混合物。
- 氨可以用于从醇直接合成伯胺。
- 在氨气存在下通过蒸汽沉积而合成N掺杂的石墨烯已被报道。

Nitrogen-doped graphene (N-graphene) was synthesized by chemical vapor deposition of methane in the presence of ammonia. The resultant N-graphene was demonstrated to act as a metal-free electrode with a much better electrocatalytic activity, long-term operation stability, and tolerance to crossover

We evaluated whether peripheral ammonia production during prolonged exercise enhances the uptake and subsequent accumulation of ammonia within the brain. Two studies determined the cerebral uptake of ammonia (arterial and jugular venous blood sampling combined with Kety-Schmidt-determined cerebral blood flow;
