Summary:The invention discloses a preparation method of a high-performance Fe-based catalyst and application of the high-performance Fe-based catalyst in green ammonia synthesis. The Fe-C microsphere catalyst is prepared by a hydrothermal method, and the metal additive is loaded, so that the additive-promoted Fe-C microsphere catalyst is obtained. A large number of experiments accidentally find that under the hydrothermal condition of 120 DEG C, when the molar ratio of iron to a carbon source is 1, the ammonia synthesis rate of the Fe-coated C120 DEG C catalyst promoted by the Cs aid at 400 DEG C and 1 MPa reaches 16.9 mmol NH3gcat <-1 > h <-1 >, and the ammonia synthesis performance of the Fe-coated C120 DEG C catalyst promoted by the Cs aid is superior to that of a typical noble metal Ru-based ammonia synthesis catalyst. The preparation method of the Fe-based carbon sphere catalyst provided by the invention is simple, has the advantage of low economic cost, and has a relatively strong industrial application prospec
