Abstract

Abstract: Ammonia is an important chemical feedstock and is produced by Ru or Fe catalyst so far. We investigated Co catalyst for low temperature ammonia synthesis in an electric field. Well-reduced Co/Ce_0.5Zr_0.5O₂ catalyst showed high activity for ammonia synthesis even at 473 K in the electric field. Various characterizations including kinetic tests, operando DRIFTS measurements, TEM observations, and XAFS measurements, revealed that the active site is the interface between supported Co and Ce_0.5Zr_0.5O₂ oxide support, thanks to the surface protonics derived from an electric field. Graphical Abstract: [Figure not available: see fulltext.].
