“…Almost, all techniques require high temperature, sophisticated instrumentation or costly chemicals. Moreover, the very low yields of BCN make these techniques quite impractical in real‐life applications . Polymer‐precursor‐based synthesis of BCN has been reported by Zhang et al., although there are a few concerns such as inadequate purity and dimensional homogeneity .…”

Two-dimensional hexagonal boron carbon nitride (BCN) nanosheets (NSs) were synthesized by new approach in which a mixture of glucose and an adduct of boric acid (H3 BO3 ) and urea (NH2 CONH2 ) is heated at 900 °C. The method is green, scalable and gives a high yield of BCN NSs with average size of about 1 μm and thickness of about 13 nm. Structural characterization of the as-synthesized material was carried out by several techniques, and its energy-storage properties were evaluated electrochemically. The material showed excellent capacitive behaviour with a specific capacitance as high as 244 F g(-1) at a current density of 1 A g(-1) . The material retains up to 96 % of its initial capacity after 3000 cycles at a current density of 5 A g(-1) .

“…But depending on their chirality, CNTs can be metallic or semiconducting [8]. BCN alloy nanotubes have been successfully synthesized by electrical arc discharge [9][10][11][12][13], pyrolysis [14,15] and laser ablation [16] methods. BCN alloy nanotubes are especially good in nanodevice applications.…”

Electronic properties of single-walled boron nitride nanotube in zig-zag form are numerically investigated by replacing B atoms with C atoms. Using a tight-binding Hamiltonian, the methods based on Green's function theory, Landauer formalism and Dyson equation, the electronic density of states and electronic conductance in boron nitride nanotube and boron carbonitride nanotube are calculated. Our calculations indicate that in a boron nitride nanotube, the localized states associated with C impurities appear as the concentration of C atoms increases. The boron carbonitride nanotube thus behaves like a semiconductor. Also, by increasing the C atom concentration, the voltage in the first step on the I-V characteristics decreases, whereas the corresponding current increases.

“…Boron and nitrogen atoms are considered as natural candidates to the doping process [2][3][4][5][6][7][8][9][10] . New growth techniques of Y, L, T, H or multi-branching [11][12][13][14][15][16][17][18][19][20] junctions constituted by nanotubes with the same chirality (or not) made researches about intermolecular junctions which increase the possibilities to built nanodevices based on carbon nanotubes ( Figure 1).…”

Theoretical analysis of formation energy and geometry was done to compare the relative stabilities of modified carbon nanostructures representative fragments. Structure and energies of formation were calculated at semiempirical level of theory. Depending of B-N pair localization on the molecular structures the formation enthalpy decreases. B-N substitution in tubular structures at low concentration decreases the energy when the tubes have small diameters. Our results are in according to experimental works which have shown that boron and nitrogen are met at region of defects in B X C Y N Z nanostructures.
