| 摘 要： | 以磁铁矿和还原剂为原料采用高温熔融法分别制得Fe_3O_4、FeO和二者不同比例的混合物，研究了FeO的非化学整比性、氧化性和亚稳定性以及以这些氧化物为母体的熔铁催化剂的活性。发现铁氧化物还原后催化合成氨的活性次序为Fe_(1-x)O＞Fe_3O_4＞Fe_2O_3＞任何两种氧化物的混合物。

| Abstract: | Fe_3O_4,FeO and their mixture were Prepared by using high temperature fusion method with magnetite and reducing reagent as raw.The physicochemical properties and crystal structure and activity of the catalyst with iron oxides as precuesor were investigated.The activity order of ammonia synthesis on iron oxide was proposed and the order of activity is as follows:Fe_(1-x)O＞Fe_3O_4＞Fe_2O_3＞mixture of any two iron oxides. |
