It is demonstrated that unique carbon nanostructures including carbon nanotubes and carbon onions are synthesized by high-speed ball-milling of steel balls. It is considered that the gas-phase reaction takes place around the surface of steel balls under local high temperatures induced by the collision-friction energy in ball-milling process

The dependence of multiwall carbon nanotube (MWCNT) length distribution and some nitrogen derived morphological descriptors on various planetary ball milling process parameters was investigated. Ball milling was found to cut nanotubes into smaller pieces, narrow their length distribution and increase their specific surface area and surface fractal dimension. Typical length reduction was from

Ball milling is regularly applied to carbon materials. Applying graphite, it was used to produce highly curved nanostructures [1], [2], to insert lithium [3] or to improve the hydrogen storage capacity of the material [4], [5]. In this paper, we propose to use this grinding method on single-wall carbon nanotubes (SWNTs).

The effects of ball milling on cup-stacked carbon nanotubes are summarized as follows. Two different cleavage modes are considered, based on TEM observations. It is expected that the bending mode plays the main role in cleaving carbon nanotubes from the viewpoint of the cup-stacked morphology of these carbon nanotubes.

Abstract. N-doped carbon materials are promising metal-free catalysts for a number of applications. In this work, a cost effective and easy method to prepare N-doped carbon nanotubes by ball milling was developed, which avoids the use of solvents and production of wastes. Melamine and urea were used as nitrogen precursors.
