Abstract:Doped carbon materials have been recognized as a promising non-Pt cathode catalyst for oxygen reduction reaction (ORR). We prepared a new Fe-N codoped carbon meterial by the carbonization of Polyaniline-Prussian blue composite (PANI-PB). PANI-PB was first prepared by doping polyaniline with ferrous ion and ferricyanide ion in turn. The composite was then carbonized in a nitrogen atmosphere at a heating rate of 10  C min-1 up to a maximum temperature of 800  C, forming a Fe-N doped carbon meterial(Fe-N/C). The product demonstrates a unique graphitized structure and has a relatively high Fe-N doping amount. The cyclic voltammetry curves (CV) show that the composite can catalyze the ORR much more efficiently than either of the single materials containing only carbonized PANI or carbonized PB in alkaline media. ?
