【Abstract】 A porous support was obtained from spherical fused iron catalyst after its potassium ions were dissolved out by water. impregnation of a mixture of Mn(Ac)2 and KNO3 on the dried porous support gives a catalyst with higher activity for ammonia synthesis. New phases of the catalyst were characterized by XRD. Influence of concentration of the impregnating solution and K+/Mn’+ mole ration the activity were also discussed.更多还原
