In this study, Palladium-Cobalt alloy catalyst was synthesized based on the graphene, and its structure was evaluated by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction tests. The results of structural tests showed that the average of particles of the synthesized catalyst was 70 nm in size, and the particles were regularly throughout the catalyst samples, and their accumulations were low. The electrochemical performance of the palladium-cobalt alloy catalyst was assessed in the ethanol oxidation at an alkaline medium into a three-electrode system. The results showed that the synthesized catalyst had significant activity in terms of the peak density of the high flux and low initiation potential in the electrochemical oxidation of the ethanol. Also, the synthesized catalyst showed excellent stability against the poisoning caused by ethanol oxidation products.
