Electrodeposition of platinum nanoparticles on reduced graphene oxide as an efficient and green catalyst for oxygen reduction reaction

Reduced graphene oxide (RGO) film synthesized on a glassy carbon electrode (GCE). Then platinum nano particles were deposited on RGO film via electrodeposition of platinum salt. Morphology of the Pt/RGO onGCE was evaluated by scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). Theperformance of Pt/RGO catalyst for oxygen reduction reaction was considered with polarization curves andelectrochemical impedance spectroscopy. The results showed the proper performance of green synthesized catalyst for oxygen reduction reaction. Therefore this catalyst is a good candidate for the cathode for PEM fuel cells
