Abstract
In this research, we synthesized Fe-N-C material from oil palm fronds with the addition of polyaniline and melamine compounds. The characteristics of the Fe-N-C material were analyzed using X-ray diffraction (XRD), raman spectroscopy, and scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDX). The XRD results showed two graphitic carbon peaks at 2θ around 26° and 44°. SEM images revealed that the Fe-N-C material has a lamellar structure with a hierarchical pore structure that facilitates diffusion of reactants. The raman spectroscopy results showed two peaks related to carbon defect band and carbon graphite band. Furthermore, the EDX results confirmed the formation of Fe-N active sites which are associated with the oxygen reduction reaction (ORR). This study provides an easy and cost-effective method for synthesizing Fe-N-C material as an ORR electrocatalyst, while also enhancing the value of oil palm frond waste.
