Controlling the size and the dispersion of Pt nanoparticle structures seems to be one of the most important goals in improving the electrochemical activity and the durability of an electrocatalyst as a Platinum nanoparticle catalyst for fuel cells. In this paper, we introduce a simple method to address the effects of temperature, pH and ethylene glycol enhancers (EG) on the morphology, the size and the distribution of the Pt nanoparticle catalyst in the process of fabricating Pt nanoparticles on carbon support (Pt NPs/C). By means of a facile method, the Pt NPs/C catalyst was synthesized with and without the use of EG at room temperature and 60oC in pH = 6.5 and 11 solutions. The morphology, the size and the dispersion of the platinum nanoparticle catalyst on carbon support were characterized via X-ray diffraction (XRD) and transmissionelectron microscopy (TEM). We have found out that the size, the morphology and the dispersion of Pt nanoparticles on carbon were strongly affected by adjusting the temperature, pH and that the presence of ethylene glycol could enhance the properties of the Pt/C catalyst for fuel cells application.
