Abstract
|
In this work, a simple and efficient synthesis method is used to fabricate Fe3O4@Pt core-shell nanoparticles. The obtained catalyst is characterized by X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy and transmission electron microscopy. The results show that the size of the Fe3O4@Pt nanoparticles, which are uniformly dispersed on carbon-ceramic, are 20-40 nm in diameters. The electrooxidation of the ethylene glycol reaction was studied on Fe3O4@Pt core-shell nanoparticles decorated carbon-ceramic substrate by cyclic voltammetry in NaOH solution. The obtained results indicate that the system studied in the present work is the most promising system for use in direct ethylene glycol fuel cells.
