Growth and characterization of BCN nanotubes with high boron and nitrogen content

Abstract

Multiwalled carbon nanotubes doped with boron and nitrogen (BCNTs) have been synthesized by chemical vapour deposition at temperatures ranging from 800 • C to 950 • C. Their morphological and structural features have been studied by transmission electron microscope, which reveal that BCNTs have bamboo-like structure. The results of X-ray photoelectron spectroscopy demonstrated that the atomic ratio of B, C and N of BCNTs is about 1:4:1, when temperature is 850 • C. Electrooxidation performance of the BCNTs for NO at the modified electrodes was investigated. The results of cyclic voltammograms and the electrochemical impedance spectroscopy of BCNT-modified electrodes indicated that the activity of NO electrooxidation on 850 • C-modified electrodes is much stronger than others and the charge transfer resistance of NO electroxidation BCNT-modified electrode is the least. By this means, BCNT-modified electrodes showed excellent electrode materials for NO detection and other potential applications.

Nanocomposites of 1D MoS2 with Polymer-Functionalized Nanotubes of Carbon and Borocarbonitride, and Their HER Activity

“…27 Meanwhile, IR spectrum of BCNNT exhibit peaks for B−N, B−C, and C−N type bonds at 1364, 1125, and 1609 cm −1 , respectively, revealing the presence of BN, C, and BCN networks (Figure S5). 30 Figure 3a show the Raman spectra of MoS 2 −P.SWCNT (1:3, 1:1, 3:1, 5:1) composites along with those of MoS 2 − C 6 H 4 COOH and P.SWCNT. The Raman spectrum of MoS 2 − C 6 H 4 COOH exhibits E 1 2g and A 1g signals from the trigonal polytype MoS 2 at 381 and 406 cm −1 , respectively, signifying functionalized nanotubes to be in the 2H-phase.…”

Temperature-Dependent Morphology Evolution of Boron Nitride and Boron Carbonitride Nanostructures

“…It is well known that applications of BN and BCN are related to their purity, size, and morphology. To date, a series of methods have been successfully developed to prepare BN and BCN nanostructures such as arc discharge [18,19], solid-state reaction [20][21][22], ball milling-annealing process [23,24], chemical vapor deposition (CVD) method [25][26][27][28][29], and other methods. However, the morphologies of the synthesized BN and BCN nanostructures were versatile and could not be controlled currently.…”
