AMMONIA DECOMOSITION CATALYST, HONEYCOMB STRUCTURE AND INTERNAL COMBUSTION ENGINE

Abstract

The present disclosure relates to an ammonia decomposition catalyst comprising a mixed oxide forming a perovskite structure with at least barium, zirconium, and ruthenium, a honeycomb structure comprising the ammonia decomposition catalyst, and an internal combustion engine comprising the ammonia decomposition catalyst. According to the present disclosure, it is possible to provide an ammonia decomposition catalyst exhibiting excellent initial activity even at low temperatures and excellent heat resistance with respect to ammonia decomposition activity, a honeycomb structure comprising the ammonia decomposition catalyst, and an internal combustion engine comprising the ammonia decomposition catalyst.
