DOI: 10.1038/s41586-026-11008-2 As a liquid that is easily stored and transported, ammonia (NH 3 ) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing and other applications. However, breaking ammonia into hydrogen and nitrogen typically requires high temperatures, and the resulting gas mixture must undergo additional purification before the hydrogen can be used in many applications.
