Developing　zinc-air　batteries　still　heavily　relies　on　the　design　of　stable,　high-activity,　and　inexpensive　oxygen-　electric　bifunctional　catalysts.　In　this　work,　transition　metal　iron　salts　converted　amorphous　carbon　into　graphitized　carbon　at　high　temperatures,　and　nitrogen-doped　graphitized　carbon-anchored　iron　nanoparticles　(Fe-N-C)　are　prepared.　Then,　Fe-N-C　is　pyrolyzed　with　selenium　dioxide　(SeO2)　2　)　to　convert　iron　(Fe)　nano-　particles　into　iron　selenide　(FeSe)　in　situ　to　obtain　nitrogen-doped　graphitized　carbon-anchored　FeSe　nano-　particle　catalysts　(FeSe/NC).　The　catalyst＇s　carbon　support　has　excellent　electrical　conductivity,　which　effectively　promotes　the　transport　rate　of　charges　and　enhances　the　catalytic　activity　of　FeSe　particles.　FeSe/NC　demonstrates　outstanding　catalytic　activity　for　both　oxygen　reduction　reaction　(ORR)　and　oxygen　evolution　reaction　(OER).　When　utilizing　FeSe/NC　catalysts　in　rechargeable　zinc-air　batteries　(ZABs-FeSe/NC),　the　most　excellent　power　density　could　exceed　186.6　mW　cm-　2　,　and　the　specific　capacity　can　achieve　905.2　mAh　g-　1　,　demonstrating　excellent　performance.　Furthermore,　the　battery　can　achieve　stable　charge-discharge　for　longer　than　200　h　at　a　large　current　density　of　10　mA　cm--　2　,　which　has　excellent　practical　application　feasibility　in　the　future.
