Ball milling effect on the structure of single-wall carbon ...

2004-1-1  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).

Easy method to prepare N-doped carbon nanotubes by

2015-9-1  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.

Effect of ball milling on morphology of cup-stacked

2002-4-2  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.
