摘要：
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 to-ward formic acid electrooxidation were investigated by cyclic voltammetry (CV) and chronoamperometry (CA). These results showed that Pt nanoparticle with the crystallite size of about 5 nm was highly dispersed on ED-Gh and the catalyst exhibited good electro-catalytic activity and long-term stability. Therefore, ED-Gh can be a potential support for Pt in direct formic acid fuel cells. Copyright (C) 2014, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
