Iron　single-atom　catalyst　in　form　of　iron-nitrogen-carbon　structure　possesses　the　excellent　catalytic　activity　in　various　chemical　reactions.　However,　exploring　a　sustainable　and　stable　single-atom　metal　catalyst　still　faces　a　great　challenge　due　to　low　yield　and　complicated　synthesis.　Here,　we　report　a　functional　multi-wall　carbon　nanotubes　modified　with　iron　phthalocyanine　molecules　via　a　liquid　chemical　reaction　and　realize　the　performance　of　similar　single-atom　catalysis　for　oxygen　reduction　reaction.　A　serial　of　characterizations　strongly　imply　the　structure　change　of　iron　phthalocyanine　molecule　and　its　close　recombination　with　multi-wall　carbon　nanotubes,　which　are　in　favor　of　ORR　catalysis.　Compared　to　commercial　platinum-carbon　catalyst,　composites　exhibit　superior　activity　for　oxygen　reduction　reaction　with　higher　half-wave　potential　(0.86　V),　lower　Tafel　slope　(38　mV　dec(-1)),　higher　limiting　current　density　and　excellent　electrochemical　stability.　The　corresponding　Zinc-air　battery　also　presents　higher　maximum　power　density　and　discharge　stability.　Therefore,　these　findings　provide　a　facile　route　to　synthesize　a　highly　efficient　non-precious　metal　carbon-based　catalyst.
