- Abstract
A novel electrocatalyst support material, nitrogen-doped carbon (CN)-modified FeO (FeO-CN), was synthesized through carbonizing a polypyrrole-FeO hybridized precursor. Subsequently, FeO-CN-supported Pt (Pt/FeO-CN) nanocomposites were prepared by reducing Pt precursor in ethylene glycol solution and evaluated for the oxygen reduction reaction (ORR). The Pt/FeO-CN catalysts were characterized by X-ray diffraction, Raman spectra, X-ray photoelectron spectroscopy, scanning electron microscopy, and transmission electron microscopy. The electrocatalytic activity and stability of the as-prepared electrocatalysts toward ORR were studied by cyclic voltammetry and steady-state polarization measurements. The results showed that Pt/FeO-CN catalysts exhibited superior catalytic performance for ORR to the conventional Pt/C and Pt/C-CN catalysts.
