Fe-polyaniline/functionalized graphene (Fe-PANI/PGO) was prepared by heat treatment and acid etching using p-phenylenediamine (PPD) functionalized graphene oxide (GO) as the support,ferric trichloride (FeCl3) as the metal precursor and polyaniline (PANI) as the nitrogen precursor,and studied the oxygen reduction performance.The results showed that Fe-PANI/PGO was able to achieve improved onset potential of -0.057V and half-wave potential of -0.122V as well as limited current of -5.145mA/cm2.At the same time,it was clarified that the excellent oxygen reduction performance of Fe-PANI/PGO was mainly attributed to the increase of defects in carbon structural,which was beneficial to increase the content of pyridinic nitrogen and graphitic nitrogen in the catalysts.
