A "symphony" of lithium-mediated ammonia synthesis (IMAGE)
Caption
This graphic art illustrates the lithium-mediated conversion of N2 to ammonia. Pictured is a symphony of reactions occurring on an electrodeposited lithium (black tiles). Under high pressure, nitrogen (addition of blue blocks) is chemisorbed on lithium, followed by protonation (addition of white blocks) to form NHx, eventually leading to ammonia and the recovery of lithium. The cyclic process creates a catalytic rhythm producing ammonia. This research highlights the significance of pressure and potential in controlling the structure and stability of the solid-electrolyte interface toward ammonia synthesis.
