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 H 2 . 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.
