Nitrogen-Doped Carbon Nanotube Fiber for Electrode Fabrication

Abstract

Carbon Nanotubes (CNTs) are the emerging materials because of their extraordinary physical and chemical properties. Diverse applications, such as chemical and biochemical sensors, electronic devices, nanocontainer lithium ion batteries, thermally stable materials, and many others have been proposed and tested. The properties of carbon nanotubes depend on their structure, such as diameter, defect density, length, chirality, number of walls, etc. Regrowth of nitrogen-doped carbon nanotubes (N-CNTs) from open end of carbon nanotube fiber is our initial focus to achieve using Chemical Vapor Deposition (CVD) method. Incorporation of Nitrogen into carbon nanotube structure leads to high surface area and high density of defects. N-doped CNTs has excellent performance in oxygen reduction reactions and enhance the energy storage capabilities of Lithium ion batteries. Fe-Al bimetallic nanoparticles synthesized by electrochemical process lead to the N-CNTs growth by CVD which is proved by initial investigation. Fabrication of electrode using N-CNTs fiber is easy because of their high conductivity, large surface area, and strong mechanical strength. The application of the electrode and necessary data will be discussed in final presentation.
