Carbon Nanotubes on Carbon Nanofibers: A Novel Structure Based on Electrospun Polymer Nanofibers

Abstract: Electrospun nanofibers of polyacrylonitrile, containing an iron compound, have been converted to carbon nanofibers, with iron particles on their surfaces. The iron particles catalyze the growth of carbon nanotubes with iron tips (see Figure). A mechanically strong and electrically conducting path exists between each metal particle and the supporting nanofiber network, which extends to macroscopic dimensions.

“…The mechanism for this process was similar to the crystallization mechanism of carbon nanotube growth from a surface. Reneker et al and Lai et al grew carbon nanostructures from electrospun carbon nanofibers with iron and palladium nanoparticles, respectively [157,185]. In the latter work, the type of carbon dictated the morphology of the resulting nanostructure.…”

“…In general, a typical adsorption-controlled process of an electron transport reaction in aqueous media is affected by the surface area of the modified electrode, where the higher the surface area is, the easier the diffusion of the electrolyte to the surface of the electrode is [27]. However, the electrocatalytic data indicate that the catalytic property of ZCF is better than CF, with good reversibility and a higher peak current on the electrocatalytic oxidation of HQ.…”

“…Electrospinning is an efficient and versatile approach for the preparation of long nanofibers, and subsequent carbonization of the electrospun nanofibers at high temperature could produce CNFs [1]. Herein, the PAN nanofibers were firstly synthesized based on electrospinning technique as the precursor of CNFs.…”

“…Electrospining technique uses the electrostatic force to produce continuous fibers with diameters ranging from a few nanometers to several micrometers from a polymeric solution. People prepared CNF and its composites, such as various metal nanoparticle-loaded CNF based on electrospinning technique [1,2]. Dopamine (DA), ascorbic acid (AA) and uric acid (UA) are compounds of great biomedical interest, playing significant roles in the functioning of the human metabolism, central nervous and renal systems [3].…”
