Preparation and application of multi-walled carbon nanotubes and metal cobalt nanoparticles composite carbon fiber electrodes

Carbon nanotubes and cobalt nano-particles were compounded to the surface of the carbon fiber by the vapor deposition method and the electrochemical deposition method respectively. In this study, novel Co@carbon nanotubes (CNTs)@carbon fiber (CF) composites were fabricated to be electrode by a simple and facile approach. It increases the specific surface area, conductivity and catalytic activity of carbon fiber electrode. It can be used to detect nitrate ions.
