were performed by using a Biologics SP-150 potentiostat, which is
a three-electrode system consisting of auxiliary, counter, and working
electrodes. In this system, Ag/AgCl is used as an auxiliary, platinum
as a counter, and gold wire as a working electrode. The synthesized
nanocomposite was characterized by FESEM to evaluate the surface morphology
using a FEI Quanta 3D FEG microscope. The crystallinity was analyzed
with X-ray diffraction (XRD) using a Rigaku Smart Lab (2θ range:
5 to 40°) diffractometer. FTIR spectra were recorded from a Bruker
Tensor 37 instrument in the range of 500–4000 cm–1. Double-distilled water was used throughout the experiment.
