Reactive hydrogen in KH or KOH for catalytic NH3 synthesis

Caption

  • K has long been employed as a key promoter for ammonia synthesis; however, its exact role remains elusive.
  • KH and KOH promote the hydrogenation of Fe nitride intermediates to form NH3 via distinct reaction pathways.
  • Hydrogen in KH (hydridic) and KOH (protonic) is involved in NH3 formation via formation of KNHx intermediates.
  • This study provides new insights into the role of alkali metals, guiding the design of efficient catalysts.
