Scaled synthesis of boron nitride nanotubes, nanoribbons, and nanococoons using direct feedstock injection into an extended-pressure, inductively-coupled thermal plasma.

چکیده
A variable pressure (up to 10 atm) powder/gas/liquid injection inductively coupled plasma system has been developed and used to produce high-quality boron nitride nanotubes (BNNTs) at continuous production rates of 35 g/h. Under suitable conditions, collapsed BN nanotubes (i.e., nanoribbons), and closed shell BN capsules (i.e., nanococoons) are also obtained. The process is adaptable to a large variety of feedstock materials.

Mass-production of boron nitride double-wall nanotubes and nanococoons
Various techniques including plasma-arc, laser ablation, and chemical vapor-phase synthesis have been employed to Ž . produce bulk amounts of non-carbon such as boron nitride, BN nanotubes with some success, but in general the yields are low. We describe a new high-yield plasma-arc method that easily and reliably produces macroscopic amounts of pure BN nanotubes. Interestingly, the method produ...
متن کاملLongitudinal splitting of boron nitride nanotubes for the facile synthesis of high quality boron nitride nanoribbons.
Boron nitride nanoribbons (BNNRs), the boron nitride structural equivalent of graphene nanoribbons (GNRs), are predicted to possess unique electronic and magnetic properties. We report the synthesis of BNNRs through the potassium-intercalation-induced longitudinal splitting of boron nitride nanotubes (BNNTs). This facile, scalable synthesis results in narrow (down to 20 nm), few sheet (typicall...
متن کاملMass spectrometric study of low-pressure inductively coupled plasma for chemical vapor deposition of cubic boron nitride films
Chemical species in plasma are crucial for understanding the mechanism of cubic boron nitride film vapor phase deposition and controlling the film structure. In this study, the plasma condition for cubic boron nitride deposition by low-pressure inductively coupled plasmaenhanced chemical vapor deposition using B2H6, N2, and Ar as reactant gases has been diagnosed by a quadrupole mass spectromet...
متن کاملSonication-assisted alcoholysis of boron nitride nanotubes for their sidewalls chemical peeling.
Boron nitride (BN)-based nanomaterials attract considerable attention due to their unique properties. In this study, we found that sonication treatment of multiwalled boron nitride nanotubes (BNNTs) in primary alcohols had led to chemical peeling of their sidewalls through alcoholysis, thereby producing boron nitride nanoribbons (BNNRs).
متن کاملElectronic and Optical Properties of the Graphene and Boron Nitride Nanoribbons in Presence of the Electric Field
Abstract: In this study, using density functional theory and the SIESTA computationalcode, we investigate the electronic and optical properties of the armchair graphenenanoribbons and the armchair boron nitride nanoribbons of width 25 in the presence of atransverse external electric field. We have observed that in the absence of the electricfield, these structures are se...
