Extensive　investigations　have　been　devoted　to　nitrogen-doped　carbon　materials　as　catalysts　for　the　oxygen　reduction　reaction　(ORR)　in　various　conversion　technologies.　In　this　study,　we　introduce　nitrogen-doped　carbon　materials　with　hollow　spherical　structures.　These　materials　demonstrate　significant　potential　in　ORR　activity　within　alkaline　media,　showing　a　half-wave　potential　of　0.87　V　versus　the　reversible　hydrogen　electrode　(RHE).　Nitrogen-doped　hollow　carbon　spheres　(N-CHS)　exhibit　unique　characteristics　such　as　a　thin　carbon　shell　layer,　hollow　structure,　large　surface　area,　and　distinct　pore　features.　These　features　collectively　create　an　optimal　environment　for　facilitating　the　diffusion　of　reactants,　thereby　enhancing　the　exposure　of　active　sites　and　improving　catalytic　performance.　Building　upon　the　promising　qualities　of　N-CHS　as　a　catalyst　support,　we　employ　heme　chloride　(1　wt%)　as　the　source　of　iron　for　Fe　doping.　Through　the　carbonization　process,　Fe-N　active　sites　are　effectively　formed,　displaying　a　half-wave　potential　of　0.9　V　versus　RHE.　Notably,　when　implemented　as　a　cathode　catalyst　in　zinc-air　batteries,　this　catalyst　exhibits　an　impressive　power　density　of　162.6　mW　cm-2.
