Abstract
The development of alternative catalyst with the economical production cost and high catalytic activity instead of Pt-based catalyst for fuel cells is good challenge. It is well known that Fe-N_4/C possesses the catalytic activity for oxygen reduction reaction, with high potential for utilization as cathode. Here, the Fe-N/C particles were synthesized using various precursors by solution plasma process (SPP). In this method, the selection of precursor can control the elemental composition of the synthesized Fe-N/C which affects to the catalytic activity. Pyridine, aniline, pyridine/aniline, and pyridine/triazine as the selected precursors were discharged to form N-carbon particles. In addition, the incorporation of Fe was achieved by the chemical complex of Fe ions. The synthesized Fe-C/N particles were characterized to confirm the elemental composition using elemental analysis. The structural analysis was done by XRD and TEM. Furthermore, the electrocatalytic activity was investigated using cyclic voltammetry under the O_2 and N_2 saturated conditions.
