Ultrafine palladium iron (FePd) nanoalloys deposited on gamma Fe2O3, FePd-Fe2O3, further anchored on carboxyl multi-walled carbon nanotubes (MWNTs-COOH), FePd-Fe2O3/MWNTs, were successfully synthesized by a facile one-pot solution based method as thermal decomposing palladium acetylacetonate (Pd(acac)2) and iron pentacarbonyl (Fe(CO)5) in a refluxing dimethylformamide solution in the presence of MWNTs-COOH. A 3.65 fold increase of peak current density was observed in cyclic voltammetry (CV) for ethanol oxidation reaction (EOR) compared with that of Pd/MWNTs after normalizing to Pd mass. The greatly enhanced tolerance stability towards poisoning species and largely reduced charge resistances were also obtained in chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS) due to the downward shifted d band center of FePd alloy, easily formed oxygen containing species on Fe2O3 and the stabilizing role of the MWNTs.
