Synthesis and Characterization of Boron Nitride Nanotubes (Bnnts) With a New Method and Precursor Materials

Abstract

Boron nitride nanotubes (BNNTs) have many application areas thanks to their superior properties such as thermal and electrical insulation, resistance to oxidation, high hydrophobicity, and high hydrogen storage capacity, as well as biocompatible properties. Therefore, new synthesis methods are being searched for BNNT with increasing interest in recent years. In this study, high purity and yield BNNTs were synthesized using precursor materials and methods that were not previously tried in the literature. A chemical vapor storage (CVD) furnace was used for the synthesis, and various parameters were changed to achieve optimum conditions. The structure of the obtained BNNTs was characterized by Fourier conversion infrared spectroscopy (FTIR), Raman spectroscopy, and a UV-visible spectrophotometer. In addition, surface morphologies were illuminated using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). However, it has been observed that BNNTs obtained as a result of HR-TEM (high-resolution transmission electron microscope) analysis have a single-walled structure that is difficult to synthesize. This increases the importance and quality of synthesized BNNTs. © 2021, Gumushane University. All rights reserved.
