摘要：

An amorphous Fe-based catalyst supported on polypyrrole-modified graphite is synthesized by a chemical method. The optimal Fe loading with the highest reduction current is 4 wt%. Their morphology, structure and chemical component were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS), respectively. The scanning electron microscopy show that the surfaces of graphite are decorated with metal nanoparticles. Under acid condition, the catalyst demonstrate high oxygen reduction reaction (ORR) activity with four-electron pathway.
