Abstract

Magnetic induction method and a-FezOJ nanowires have been proven to be able to produce ammonia and urea under ambient temperature and pressure but it lacks fundamental understanding of the mechanism of magnetic induction to affect the reaction equilibrium. Therefore, the effect of the a-FezOJ nanowires morphology and the process parameters were observed. The acid concentration that used for wire treatment, synthesis temperature and duration are the significant factors that will affect the morphology of the a-Fez OJ nanowires. The best a-FezOJ nanowires can be produced by simple annealing method under the condition of 620 oc of synthesis temperature, 110 min of synthesis duration and 16 M of HzS04 concentration for acid treatment
