Abstract

The aims of this study is to analyze the new material substitute for Pt/C catalyst with the main material Fe as a metal precursor, graphite as carbon, and variations of nitrogen derived from organic compounds. The homogenous mixing generated a nitrogen-coated carbon surface after pyrolysis. Nitrogen and carbon were fixed in the ratio of 1:1 and mixed with the compound FeCl₃.6H₂O dissolved with ethanol. The percentage of Fe was 7wt%. Pyrolysis was carried out at 700°C for 2 hours under N2 atmosphere. The formation of new compounds after pyrolysis, such as FeS and Fe₂O₃, has a role to increase catalytic activity. The Fe-N (urea + PVP) -C catalyst has the largest CV and current density area compared to the Fe-N (urea) -C and Fe-C catalysts. These results are caused by the largest surface area of 7.239 m^²/g of Fe-N (urea + PVP) -C and have a uniform distribution of nitrogen on the carbon surface as shown by the SEM observation image. In addition, the good electrochemical properties of the Fe-N (urea + PVP) -C catalyst due to the high nitrogen content of the EDX analysis of 2.97 wt% demonstrate it is possible to form nitrogen functional groups after pyrolysis.
