In situ formed Co from a Co–Mg–O solid solution synergizing with LiH for efficient ammonia synthesis

Abstract

A cobalt magnesium oxide solid solution (Co–Mg–O) supported LiH catalyst has been synthesized, in which LiH functions both as a strong reductant for the in situ formation of Co metal nanoparticles and a key active component for ammonia synthesis catalysis. Dispersion of the Co–LiH composite on the Co–Mg–O support results in a significantly higher ammonia synthesis rate under mild reaction conditions (19 mmol g−1 h−1 at 300 °C, 10 bar).
