Abstract
Iron/iron carbide-inserted carbon nanotube/graphite composite (Fe-C) was prepared by pyrolyzing amixture of melamine and iron (III) chloride to form a support for high loading of Pt nanoparticles as adirect ethanol fuel cell anode catalyst. The obtained Fe-C was characterized by Raman spectroscopy, X-raydiffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy. The Fe-C surfacecharacteristics supported a high (40 wt%) loading of Pt nanoparticles with uniform dispersion and smallparticle size. Compared to Vulcan carbon-supported Pt (40 wt%), Fe-C-supported Pt exhibited enhancedcatalytic activity for CO and ethanol oxidation, and high stability due to the effect of the Fe-C supportmaterial.
