Natural　organisms　contain　rich　elements　and　naturally　optimized　smart　structures,　both　of　which　have　inspired　various　innovative　concepts　and　designs　in　human　society.　In　particular,　several　natural　organisms　have　been　used　as　element　sources　to　synthesize　low-cost　and　environmentally　friendly　electrocatalysts　for　the　oxygen　reduction　reaction　(ORR)　in　fuel　cells　and　metal-air　batteries,　which　are　clean　energy　devices.　However,　to　date,　no　naturally　optimized　smart　structures　have　been　employed　in　the　synthesis　of　ORR　catalysts,　including　graphene-based　materials.　Here,　we　demonstrate　a　novel　strategy　to　synthesize　graphene-graphite　films　(GGFs)　by　heating　butterfly　wings　coated　with　FeCl3　in　N-2,　in　which　the　full　power　of　natural　organisms　is　utilized.　The　wings　work　not　only　as　an　element　source　for　GGF　generation　but　also　as　a　porous　supporting　structure　for　effective　nitrogen　doping,　two-dimensional　spreading,　and　double-face　exposure　of　the　GGFs.　These　GGFs　exhibit　a　half-wave　potential　of　0.942　V　and　a　H2O2　yield　of　＜　0.07%　for　ORR　electrocatalysis;　these　values　are　comparable　to　those　for　the　best　commercial　Pt/C　and　all　previously　reported　ORR　catalysts　in　alkaline　media.　This　two-in-one　strategy　is　also　successful　with　cicada　and　dragonfly　wings,　indicating　that　it　is　a　universal,　green,　and　cost-effective　method　for　developing　high-performance　graphene-based　materials.
