Longitudinal Splitting of Boron Nitride Nanotubes for the Facile Synthesis of High Quality Boron Nitride Nanoribbons

Abstract

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 (typically 2-10), high crystallinity BNNRs with very uniform widths. The BNNRs are at least 1 μm in length with minimal defects within the ribbon plane and along the ribbon edges.

“…However, unlike the MWCNT/GNR synthesis, subsequent edge-functionalization has only been proposed rather than demonstrated. 488 More recently, associative protonation with chlorosulfonic acid has been shown to dissolve micron-length BNNTs, 489 preferentially to synthesis side-products, facilitating a simple purification procedure. 490 …”

Synthesis of boron and nitrogen co-doped carbon nanofiber as efficient metal-free electrocatalyst for the VO 2+ /VO 2 + Redox Reaction

“…Such variation of forming three-dimensional complex web structure probably could be explained from topological point and the formation of defects [17][18][19]. It is thought in general that local stresses generated at the surface during the complex growth of BN-CNF may provide a favorable condition for CNF coalescence [17]. Besides, it has been confirmed the important role of vacancies and dangling bonds in the creation of joints, and suggested that the formation of such joints is energetically favourable [18][19].…”

Catalyzed synthesis of rhombohedral boron nitride in sodium chloride molten salt

“…Suppose that Na (vapor) or the Na (liquid) is adsorbed by the t-BN powders. As t-BN is linked by weak interatomic interactions (van der Waals forces), the sodium atoms could infiltrated into BN layers gradually at the defect of the BN layer [33], boron nitrogen intercalation compounds may be formed in the powders [34,35]. The B 3 N 3 hexagon layers in t-BN are stacked roughly parallel to each other with a random rotation and translation about the layer normal [5].…”
