Title: Fabrication, Characterization and Potential Applications of Boron Nitride Nanofibers
Abstract: The present study concerns the fabrication of hexagonal boron nitride (h-BN) nanofibers from a mixture of boron (B), magnesium oxide (MgO), and maghemite (γ-Fe2O3) powders via a simple chemical vapor deposition (CVD) technique. A relatively long annealing and growth duration of 2 h at 500°C and 1000°C, respectively, was utilized in this synthesis. The synthesized samples seem to have boron nitride fibers (BNFs) of irregularly curved human hair-like morphologies in lower resolution and solid cylinder-like structures in high-resolution transmission electron microscopy. The presence of boron and nitrogen in the synthesized BNFs sample was confirmed via the B 1 s peak at 190.7 eV and N 1 s peak at 398.3 eV in the X-ray photoelectron spectroscopy (XPS) survey whereas a major peak at 1370 (cm− 1) in the Raman spectrum corresponds to the vibration of the E2g mode in h-BN. The sharp peaks in the X-ray diffraction (XRD) pattern verify the h-BN phase and the highly crystalline nature of the synthesized BNFs. The low density, large surface area, high porosity, and tight pore size make the nanofibers suitable for a wide range of applications from medical to consumer products and industrial to high-tech applications.
