Abstract :

Recently, the advancement of the electrocatalysts for alternative energy sources such as hydrogen and fuel cells are drawing more attention since energy sources in an attempt to relieve the pollution and energy crises. These days Pd nanoparticles are promising anode catalysts of fuel cells due to their better catalytic activity for electro-oxidation of methanol, ethanol and formic acid. Pd based catalysts are much cheaper and exhibit potential advantages in applications of fuel cells compare with Pt-based catalysts which have been extensively investigated. A facile electrochemical route was used to synthesize PdAu@Nafion-graphene at room temperature. The morphologies of the prepared PdAu@ Nafion-graphene nanocomposite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectrometer (EDS), X-ray diffraction (XRD), The electrocatalytical activities of prepared catalyst were evaluated using cyclic voltametry (CV). PdAu@Nafion-graphene nanocomposite showed highly enhanced electrocatalytical activity and stability towards the electrooxidation of methanol and formic acid.
