摘要
A Co-N-doped carbon material was synthesized by pyrolyzing a mixture of boiled egg white and cobalt nitrate. X-ray diffraction, Raman spectrum, X-ray photoelectron spectroscopy, and scanning electron microscopy were used to investigate the morphology and structure of the synthesized carbon material. Electrochemical analyses show that the Co-N-doped carbonized egg white produced much higher oxygen reduction reaction (ORR) activity and greater stability than the N-doped sample control. In conclusion, the facile method to prepare a high-activity, non-precious metal, ORR catalyst using biomass as the carbon source, offers a step towards the development of low-cost fuel cell catalysts.
