Operando probing of the surface chemistry during the Haber-Bosch process.

ABSTRACT: The large-scale conversion of N₂ and H₂ into NH₃ (refs. ^1,2) over Fe and Ru catalysts³ for fertilizer production occurs through the Haber-Bosch process, which has been considered the most important scientific invention of the twentieth century⁴. The active component of the catalyst enabling the conversion was variously considered to be the oxide⁵, nitride², metallic phase or surface nitride⁶, and the rate-limiting step has been associated with N₂ dissociation^7-9, reaction of the adsorbed nitrogen¹⁰ and also NH₃ desorption¹¹. This range of views reflects that the Haber-Bosch process operates at high temperatures and pressures, whereas surf
