Problems solved by technology

For the preparation of one-dimensional metal-doped carbon-based materials, the preparation process is complicated, the material morphology is not ideal, and the difficulty of agglomeration is easy. The doped metal nanoparticles are not uniformly dispersed, and the metal doping and synthesis of one-dimensional carbon are completed in one step. The base material provides a method for preparing a metal-doped hollow carbon nanofiber membrane material with a simple process, and uses the product to prepare γ-Fe 2 o 3 Doped Carbon Nano Hollow Fiber Membrane

Abstract

The invention relates to a preparation method of a gamma-Fe2O3-doped hollow carbon nanofiber membrane material. The method comprises the specific steps of (1) preparing a precursor; (2) preparing an anodised aluminium AAO template with the precursor; (3) calcining the anodised aluminium AAO template assembled with the precursor to obtain gamma-Fe2O3-doped hollow carbon nanofibers in a template nanochannel, and placing the calcined AAO template in a NaOH solution to remove the anodised aluminium template; (4) preparing gamma-Fe2O3-doped hollow carbon nanofibers; (5) dispersing the prepared gamma-Fe2O3-doped hollow carbon nanofibers in an ethyl alcohol solution, using a syringe for extraction, adding liquid on a bare glassy carbon electrode surface dropwise, and obtaining the gamma-Fe2O3-doped hollow carbon nanofiber membrane material after airing and film-forming are conducted at a room temperature. Metal nanometer particles are evenly dispersed in the hollow fibers, the shape is straight, and is in accordance with that of the template channel, moreover, the hollow fibers are independent from one another, and have a high degree of graphitization, and the crystal forms of the metal particles dispersed in the hollow fibers are complete.
