Laser-induced unzipping of carbon nanotubes to yield graphene nanoribbons

Abstract

Irradiation of undoped and doped multi-walled carbon nanotubes by an excimer laser (energy ∼200-350 mJ) yields graphene nanoribbons (GNRs). The GNRs so obtained have been characterized by transmission electron microscopy, atomic force microscopy and Raman spectroscopy.

The New Graphene Family Materials: Synthesis and Applications in Oxygen Reduction Reaction

“…Usually, the GNRs can be obtained by unzipping CNTs [34,[59][60][61][62][63], cutting graphene [64][65][66] and cracking graphite [67,68]. Among them, employing the CNTs as the source to get the GNRs is mostly used in the literature because of the mature and large-scale availability of CNTs.…”

“…Among them, employing the CNTs as the source to get the GNRs is mostly used in the literature because of the mature and large-scale availability of CNTs. Much effort has been dedicated to longitudinal unzipping of the CNTs, such as selective etching [59,61], chemical attacking [34,60,62,63], nanoparticle cutting [69,70] and metal atom intercalation [71,72]. In the team of James M. Tour, a simple solution-based oxidative approach using KMnO 4 and H 2 SO 4 was developed [34].…”

Pulsed ultra-violet laser interactions with ultra-low-density porous carbon nanotube sponges

“…Laser interactions with solid materials have received considerable attention for applications such as thin film growth [1][2][3][4][5], laser writing [6,7], laser-induced forward transfer [8,9], lithography and creating microstructures [10,11]. For example, in pulsed laser deposition (PLD), the pulsed laser beam is used to ablate the target material and induces a plasma plume in order to grow thin film materials with complex compositions [1,2].…”

Characterization of Laser-Induced Defect Sand Modification in Carbon Nanotubes by Raman Spectroscopy

“…The laser irradiation can lead to the heating followed by burning. Such laser irradiation also gives rise to interesting effects such as the production of defects and the modification of CNTs [3][4][5][6][7]. This chapter presents our recent studies [8][9][10][11] on laser-induced effects in SWCNTs.…”
