N2 adsorption/desorption isotherms and the Bar‐rett‐Joyner‐Halenda（BJH）pore‐size distribution（Fig.S1）are key to elucidating the structures of the formed nanocarbons.The pore sizes of the samples containing nanotubes（i.e.，Fe N‐CNT/CS and Fe N‐CNT）are in the range of~0–100 nm；in comparison，the pore sizes of N‐CS are in the range of~50–1000 nm.Therefore，the Brunauer‐Emmett‐Teller（BET）surface areas（BSAs）and total pore volumes（TPVs）of Fe N‐CNT/CS and Fe N‐CNT can be attributed to the mesoscale pores.Table 1 shows that the BSA and TPV values of Fe N‐CNT/CS are 177 m2/g and 0.41 cm3/g，respectively，which facilitate the dispersion of the Fe‐Nx species.Both the single materials provided lower BSA and TPV values:68 m2/g and0.21 cm3/g，respectively，for Fe N‐CNT and 160 m2/g and 0.36cm3/g，respectively，for N‐CS.From these results，it is reasona‐ble to propose that there is an effective synergy between the nanotubes and CS in Fe N‐CNT/CS that does not occur in the absence of either component.This supports that the CS tem‐plate promotes both the formation of Fe‐Nx active sites and ORR performance.
