FeS/FeNC decorated N,S-co-doped porous carbon for enhanced ORR activity in alkaline media

A novel strategy is developed to produce an FeS–FeNC-decorated hierarchical porous N,S-co-doped carbon (FeS–FeNC@NSC) electrocatalyst via introducing volatile FeCl3 into a porphyrin polymer framework followed by carbonization. The synergistic effect between the FeS nanoparticles and FeNC active sites in FeS–FeNC@NSC is beneficial for enhancing the ORR activity.
