Texturising and structurising mechanisms of carbon nanofilaments during growth

Abstract: The question of how the texture and structure of carbon nanofilaments (CNTs) are determined during growth is addressed via their preparation using the vapour phase method over Ni-Cu-Mg-Al catalysts. The CNTs formed and the related catalyst particles were investigated by high resolution transmission electron microscopy, electron diffraction, and X-ray energy dispersive spectroscopy. The nanofilament features were found to directly relate to the catalyst particle size and morphologies, which in turn depend on bo… Show more

“…Also, the deformation of the catalyst during the growth of graphene layers plays a crucial role in producing the CNFs with a variety of graphene layer alignments (Monthioux et al 2007), because the graphene layer is formed while mimicking the interfaces of catalyst particles (Zheng et al 2006;Rodriguez et al 1995). Zheng et al obtained platelet CNF from granular thin catalyst flakes (several tens of nanometers thick and 100-300 nm wide).…”

“…3e and f). The octopus CNFs are mostly observed from bigger Ni particles, which is in agreement with previous studies [38,[41][42][43][44][45][46][47]. Several effects, such as particle size, surface reconstructions, exposed facets and rate of ethylene decomposition, were proposed to explain the CNF growth preferences [48][49][50][51].…”
