The magnetic induction method has been proven to enable the production of ammonia under ambient temperature and pressure. However, there is a lack of fundamental understanding of the mechanism of magnetic induction to affect the synthesis of ammonia. Therefore, both the effect of a nanocatalyst and the process parameters on the ammonia yield was observed in this study. There are three objectives in this project; the first is.to synthesize and characterize YIG and a-Fe203 nanocatalysts for ammonia and urea production; the second is to synthesize ammonia at ambient conditions via the magnetic induction method; and the third is to synthesize urea directly from a mixture ofN2, H2, and C02 via the magnetic induction method using aFe203 nanowires. FESEM, XRD, EDX, raman spectroscopy, HRTEM, andFTIR were utilized to characterize the nanocatalysts.
