Manganese-iron alloy material could be potentially utilized in atmospheric ammonia synthesis in a 2-step catalytic process. In this work, a facile and scaleup synthesis of Fe-Mn alloy Nanoparticles (NP’s) by a non-traditional inductive heating method is reported. Inductive heating provides a rapid temperature rise necessary to control the nucleation and growth of nanoparticles during colloidal synthesis. The inductive heating method is the safer method for the synthesis of NP’s as it avoids the use of strong reducing agents (NaBH<sub>4</sub>, LiAlH<sub>4</sub>) and etching agents like (HF). We demonstrate that with the help of inductive heating technique Fe, Mn and Fe-Mn NP’s can be produced in few seconds. The synthesized alloy Fe-Mn NP’s can potentially applicable in the manufacture of ammonia gas which can replace the traditional Haber- Bosch process of manufacture of ammonia.
