A General Strategy for the Synthesis of Carbon Nanofibers from Solid Carbon Materials

Abstract

Carbon nanofibers were synthesized from common solid carbon sources (such as artificial graphites and acetylene black) in the presence of an iron catalyst by direct carbonization. This inexpensive and simple method is expected to trigger a revolution in the preparation of nanocarbons.

From solid carbon sources to carbon nanotubes: a general water-assisted approach

“…We previously reported that solid state carbon sources can be transformed into carbon nanobers at the high temperature of 1500 C without water vapor. 10 In brief, Fe@C eutectic spheres were initially formed by the reaction between highly oxidized carbon sources and the catalyst of iron nanoparticles in solid phase. Aer the subsequent diffusion and precipitation of the carbon component throughout the molten metal, carbon nanobers were fabricated along with the formation of micrometer carbon shells on the surface of the metal spheres.…”

“…2,7,8 However, along with the increasingly serious resource, environmental and energy problems worldwide, to satisfy the efficient utilization of chemical resources, simple approaches for the largescale preparation of various CNTs from low value-added carbon precursors are still urgently demanded. Previously, our group proposed that carbon nanobers can be prepared from solid state carbons under the treated temperature of 1500 C. 10 Biris et al reported that graphene could be converted into CNT via gold nanoparticles under relatively low temperatures. 11 However, to the best of our knowledge, the preparation of CNTs from solid carbon sources is still a great challenge until now.…”

Nanostructured Electrocatalysts for All‐Vanadium Redox Flow Batteries

“…In contrast to 0‐D carbon nanoparticles in which electrons are transferred by hopping or diffusion, one‐dimensional (1‐D) nanostructures give rise to efficient charge transfer through a continuous network, thus showing better electron‐transfer kinetics with reduced contact resistance . Yan and coworkers have intensively studied various carbon nanotube‐based electrocatalysts such as modified multi‐walled carbon nanotubes (MWCNTs) and single‐walled carbon nanotubes (SWCNTs) .…”

Facile synthesis of carbon nanobranches towards cobalt ion sensing and high-performance micro-supercapacitors

“…Reagent-grade potato starch, polyvinyl alcohol (PVA), and 4,7,10-trioxa-1,13-tridecanediamine (TTDDA) were purchased from Aldrich. Thermoplastic polyurethane (TPU) was supplied by Wanhua Chemical Group Co., Ltd. Reagent-grade N,Ndimethylformamide (DMF), dichloromethane (CH 2 Cl 2 ), trichloromethane (CHCl 3 ), acetone, tetrahydrofuran (THF), methanol, concentrated nitric acid (HNO 3…”
