摘要: We developed a single step thermal method to synthesize platinum nanoparticle functionalized graphene sheets (Pt-G) through the treatment of graphite oxide (GO) with acetylacetonate (Pt(acac)2). The loading concentration nanoparticles (Pt NPs) on is about 22.3 wt%. investigate Pt NP functionalization and reduction effects GO by scanning electron microscopy, transmission X-ray diffraction (XRD), photoelectron spectroscopy (XPS), thermogravimetric analysis Raman spectroscopy. results lead insights into formation Pt-G starting from upon increasing temperature. XPS XRD confirm that deposition accompanied exfoliation GO. Electrochemical studies reveal shows excellent activity stability towards methanol oxidation reaction.
