Description |
Activated carbon is synthesized using orange peel as precursor through chemical activation
using H3PO4 and its ability as electrocatalyst support for ORR reaction is examined. The prepared
material was subjected to various structural, compositional, morphological and
electrochemical studies. For ORR activity, the platinum loaded on activated carbon (Pt/OP-AC)
was investigated by cyclic voltammograms (CVs) recorded in N2 and O2 saturated 0.1 M aqueous
HClO4. For supercapacitor performance, three electrode systems was tested in aqueous H2SO4 for
feasibility determination and showed electrochemical double layer capacitance (EDLC) behaviour
which is expected for activated carbon like materials. Electrochemical surface area (ECSA) of the
activated carbon from orange peel is measured using CV. The physical properties of the prepared
carbon are studied using SEM (scanning electron microscope), XRD (X-ray diffraction), Fourier
transform infrared (FT-IR) spectroscopy and Raman spectroscopy. The AC derived from orange
peels delivered a high specific capacitance of 275 F g
�1 at 10 mV s-1 scan rate. Hence, this study suggested
that orange peels may be considered not only as a potential alternative source for synthesizing
carbon supported catalyst for fuel cell application but also highlight the production of low-cost
carbon for further applications like supercapacitors.
