NOVELTY - Preparing nano-iron carbide particle composite carbon-based conductive film comprises (i) electrifying at both ends of the carbon-carbon conductive membrane, (ii) using generated Joule heat response to rapidly heat iron-containing raw materials loaded on the thin film, and (iii) using an iron source to react with the carbon source in the film to obtain iron-carbon nanoparticle that are uniformly loaded on a carbon film, so that the composite film is needed to obtain the product. USE - The method is useful for preparing nano-iron carbide particle composite carbon-based conductive film, which is useful for electrode material. ADVANTAGE - The method replaces heating process of the traditional tubular furnace or the box type furnace by using the joule heat generated after electrifying nano carbon-based macroscopic film with fast lifting and cooling characteristics. The process has simple steps, fast synthesis, and low energy consumption.
