Abstract

Abstract: In this work, an active and stable electrocatalyst for alkaline electrolyte oxygen reduction reaction was prepared by using single-wall carbon nanotubes with high specific surface area as the carbon source, and polyaniline and melamine as dual nitrogen sources via high-temperature pyrolysis process. Electrochemical experiments suggest that the metallic cobalt in the precursor can facilitate the oxygen reduction reaction to be carried out with an efficient 4-electron transfer pathway. Besides, the prepared catalyst has exhibited superior tolerance against methanol crossover effect and outstanding stability compared with commercial Pt-based catalysts in alkaline medium.
