Abstract
A novel and simple synthesis method of preparing ethylene diamine (ED) functionalized graphene (ED-Gh) decorated with Pt nanoparticle has been reported. Morphology, microstructure of the resulted material was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy (Raman), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). Electrochemical studies toward formic acid electrooxidation were investigated by cyclic voltammetry (CV) and chronoamperometry (CA). These results showed that Pt nanoparticle with the crystallite size of about 5Â nm was highly dispersed on ED-Gh and the catalyst exhibited good electrocatalytic activity and long-term stability. Therefore, ED-Gh can be a potential support for Pt in direct formic acid fuel cells.
