A　series　of　NiS-FeS/N,　S　co-doped　carbon　(NixFey-S/NSC)　for　electrochemical　oxygen　evolution　reaction　(OER)　were　synthesized　by　a　co-precipitation　method　and　followed　by　pyrolysis　in　N-2　atmosphere.　NiS-FeS　hybrid　was　uniformly　integrated　with　N,　S　co-doped　carbon　in　NixFey-S/NSC.　NixFey-S/NSC　showed　high　OER　catalytic　activity,　and　the　optimized　Ni60Fe40-S/NSC　afforded　an　OER　overpotential　of　similar　to　239　mV　to　deliver　a　current　density　of　10　mA　cm(-2)　and　showed　a　corresponding　Tafel　slope　of　similar　to　30.9　mV　dec(-1)　in　1　M　KOH.　Such　OER　catalytic　activity　was　not　only　higher　than　that　of　IrO2,　but　also　comparable　with　that　of　the　most　recently　reported　NiFe-based　sulfides　for　OER.　Further　study　indicated　that　hybridizing　NiS　with　FeS　resulted　in　a　synergistic　effect　for　OER.　The　hybridization　increased　total　amount　of　sulfides　as　active　species,　therefore　enhancing　the　OER　catalytic　activity.　In　addition,　the　hybridization　benefited　the　formation　of　petal-like　morphologies　that　contributing　much　to　higher　electrochemically　active　surface　area　(ECSA),　and　also　boosted　the　content　of　graphitic　and　N,　S　co-doped　carbon　that　improving　charge　transfer　efficiency.
