In Situ Formed Co From A Co-Mg-O Solid Solution Synergizing With Lih For Efficient Ammonia Synthesis

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 degrees C, 10 bar).
