abstract={Pt-Ir@C and Pt@C catalysts were prepared by ethylene glycol method and tested for methanol and ethanol in H<SUB>2</SUB>SO<SUB>4</SUB> electrolyte. The electrocatalytic activity of these electrocatalysts was investigated using cyclic voltammograms (CVs), linear sweep voltammograms (LSVs), chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS). Their CVs show that Pt<SUB>40</SUB>Ir<SUB>60</SUB>@C catalyst present significantly high current of methanol and ethanol oxidation compared to the other catalysts. Moreover, chronoamperometric measurements showed that the steady-state current of Pt<SUB>40</SUB>Ir<SUB>60</SUB> catalyst was also higher than other electro-catalysts. EIS analysis shows that the impedances on both the imaginary and real axes are much lower than those of the other catalysts. As a result, electrocatalytic activity measurements indicated that the Pt<SUB>40</SUB>Ir<SUB>60</SUB> catalyst was the most active electrode for methanol and ethanol oxidation.},
