Pt/C and Pt/CNT catalysts were prepared by colloidal method using sodium citrate as a stabilizer, and ethylene glycol as the reducing agent and solvent. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) results showed that the Pt particles were highly dispersed on the support and had a very narrow particle distribution with particle size range of 1.5–2.4 nm for both catalysts. Based on the electrochemical properties characterized by cyclic voltammetry, it was found that the as-synthesized electrocatalysts possessed a significantly higher catalytic activity than those of commercial Pt/C Johnson Matthey catalyst.
