Continuous ammonia synthesis from water and nitrogen via contact electrification
Abstract
The Haber-Bosch process for the synthesis of ammonia is one of the important reactions that affect the development of human civilization. Nevertheless, finding a hydrogen source other than methane is receiving much attention for making a more sustainable planet. A previous study demonstrated that ammonia can be synthesized from N2 by spraying water microdroplets onto an iron oxide catalyst, but scaling up this process remains a challenge. This study shows that ammonia can also be produced from N2 during a contact process between bulk water and polytetrafluoroethylene (PTFE) particles. This process offers a promising approach for continuous ammonia synthesis on a large scale with low energy consumption under mild conditions.
