Ammonia cracking is an endothermic reaction. In the presence of a catalyst, the temperature that is necessary to decompose ammonia is significantly reduced. Ruthenium has been found to be the most active metal for the ammonia cracking reaction, strongly outperforming non- ruthenium catalysts.
Heraeus Precious Metals offers ruthenium catalysts with precious metal loadings
starting between 0.1 and 2 wt% and in different geometries
