Herein,　we　synthesized　a　Fe,　Ni　dual-metal　embedded　in　porous　nitrogen-doped　carbon　material　to　endow　higher　turnover　frequency　(TOF),　lower　H2O2　yield,　and　thus　superior　durability　than　for　the　single-atom　catalyst　for　oxygen　reduction　in　acid　media.　Quantitative　X-ray　absorption　near　edge　structure　(XANES)　fitting　and　density　functional　theory　(DFT)　calculation　were　implemented　to　explore　the　active　sites　in　the　catalysts.　The　results　suggest　FeNi-N-6　with　type　I　(each　metal　atom　coordinated　with　four　nitrogen　atoms)　instead　of　type　II　configuration　(each　metal　atom　coordinated　with　three　nitrogen　atoms)　dominates　the　catalytic　activity　of　the　noble-metal　free　catalyst　(NMFC).　Further,　theoretical　calculation　reveals　that　the　oxygen　reduction　reaction　(ORR)　activity　trend　of　different　moieties　was　FeNi-N-6　(type　I)　＞　FeNi-N-6　(type　II)　＞　Fe-N-4　＞　Fe-2-N-6.　Our　research　represents　an　important　step　for　developing　dual-metal　doping　NMFC　for　proton　exchange　membrane　fuel　cells　(PEMFCs)　by　revealing　its　new　structural　configuration　and　correlation　with　catalytic　activity.
