Investigation of carbon nanofiber supported iron catalyst preparation by deposition precipitation
An ammonia synthesis using magnetic field to replace Haber-Bosch�s ammonia production is great technological challenge in novel magnetized catalysts area. The carbon nanofiber supported iron catalyst was prepared by modifying carbon nanofiber support surface and later using urea to precipitate iro...
