CVD growth of carbon nanofibers

Abstract

This review summarizes the growth and structural properties of carbon nanofibers (CNFs) using microwave plasma‐enhanced chemical vapor deposition (MPCVD) technique and metal particles as the catalysts. The reaction gases were hydrocarbon and H2. Depending on catalyst materials, different types of CNFs have been grown. A four‐step growth mechanism, namely adsorption, desorption, diffusion, and precipitation, is proposed to demonstrate the growth of CNFs under those conditions. The growth of carbon nanohelices (CNHs) is explained by the hexahedron morphology of the catalyst particles and difference in growth velocities on crystallographic surface planes. The appeared and potential applications of CNFs are outlined at the end of this review.

Low-temperature growth of nitrogen-doped carbon nanofibers by acetonitrile catalytic CVD using Ni-based catalysts

“…The use of carbon nanofibers (CNFs) is being expanded to improve the performance of industrial products, such as batteries, supercapacitors, solar cells, sensors, catalysts, and adsorbents, because CNFs have excellent electrical, thermal, mechanical, and physicochemical properties resulting from their unique carbon nanostructure and morphologies (Desmaris et al 2015;Feng et al 2014;Jiang 2014;Peng et al 2016;Song and Shen 2014;Zhang et al 2014Zhang et al , 2016. Recently, the biocompatibility of CNFs has attracted attention, and the biomedical applications of CNFs [e.g., bone regeneration, biosensors, and antibiotic materials (Ashfaq et al 2016;Erdem et al 2015;Gao et al 2016;Stout 2015;Zhang et al 2014)] have increased.…”

Carbon Materials: Surface Chemistry and Biomedical Applications

“…According to these diverse topics, the papers are organized in three main sections: (i) the growth of carbon materials and the elaboration of composites; (ii) surface modifications and functionalization of carbon materials; and (iii) their applications. Two selected Feature Articles summarize the CVD growth of carbon nanofibers (Xin Jiang, University Siegen) and carbon nanomaterials for culturing of bone cells (Lucie Bacakova et al, Academy of Science of the Czech Republic) .…”
