Abstract

Well-designed novel dual core-shell g-C3N4@Fe/Sr@g-C3N4 nanosphere (FSCN-NS) is originally reported in detail as high efficiency of oxygen reduction reaction (ORR) electrocatalyst in both acidic and alkaline media for fuel cell. The g-C3N4 as the catalyst carrier plays a critical role in facilitating the formation of the hierarchically porous architecture with large numbers of Fe3C, FeNx(x = 1
