NOVELTY - Preparing iron-doped porous carbon nanotube electrode material comprises (a) uniformly mixing carbon support substrate, polymerized monomer and acidity regulator to obtain material A, where the carbon support substrate is graphene oxide, the polymerization monomers are methyl orange and pyrrole monomers, and the acidity regulator is ferric chloride; (b) transferring the material A to a nickel boat and placing in a tube furnace, heating from room temperature to 330℃ for 60 minutes in an inert gas atmosphere, heat preserving for 120 minutes, heating to 600℃ at a heating rate of 5℃/minute, heat preserving for 120 minutes, and naturally cooling to room temperature to obtain material B; and (c) washing material B for 2-3 times with 2 M hydrochloric acid solution, drying at 105℃ for 12 hours, where the iron-doped porous carbon nanotube electrode material has a specific surface area of 500-1200 m2/g, and contains large number of micropores and mesopores. USE - The method is useful for preparing iron-doped porous carbon nanotube electrode material. ADVANTAGE - The electrode material is simple and easy to operate, and has better promotes the large-scale application of the oxygen reduction reaction electrode material.
