Abstract:

A novel hybrid material(Fe9S10/NSPC) comprising of Fe9S10 nanocrystals and nitrogen/sulphur-codoped porous carbon(NSPC) was synthesized via a facile pyrolysis procedure followed by an acid leaching process. X-Ray diffraction(XRD), scanning electron microscope(SEM), transmission electron microscope(TEM) and X-ray photoelectron spectroscopy(XPS) techniques were used to characterized the crystal phase structure, morphology and chemical composition of the as-obtained catalysts, respectively. In addition, rotating disk electrode(RDE) and rotating ring-disk electrode(RRDE) techniques were conducted to evoluate the electrocatalytic activity of the catalysts for oxygen reduction reaction(ORR). The results show that the Fe9S10/NSPC-900(where 900 ℃ represents the pyrolysis temperature) exhibits high ORR activity, good stability and excellent methanol resistance in an alkaline medium.
