▎ 摘　　要

NOVELTY - Preparing iron-nitrogen-carbon nano electro-catalyst material involves using electro-spinning technology, using polyvinyl chloride or polyacrylonitrile as a fiber-forming template, adding high-conductivity graphene or a small layer of graphene and iron salt to the spinning solution, using three-dimensional precursor material which comprises polymer-based composite nanofibers on a collecting plate. The nano-electrocatalyst material with macroporous structure is constructed by iron-nitrogen-carbon nanofibers which is obtained through pre-oxidation and carbonization processes. USE - Method for preparing iron-nitrogen-carbon nano electro-catalyst material. ADVANTAGE - The method enables to prepare iron-nitrogen-carbon nano electro-catalyst material that has dynamics performance.
