| Abstract Scope |
In this work, electrospinning with subsequent heat treatment were employed to manufacture Nb2O5 nanowires. In the first step, using electrospinning from the solution of PVP and various weight concentrations of NbCl5, composite nanofibrous PVP/NbCl5 mats were obtained. As-spun mats were calcined in air at temperatures ranging from 400 to 600 °C to remove the polymer matrix and form pristine Nb2O5 nanowires. In order to study the morphology and structure of obtained nanostructures, a electron microscopes (SEM, TEM) were used. The chemical structure and composition were examined using Fourier-transform infrared spectroscopy (FTIR) and energy dispersive spectrometry (EDX), respectively. The polycrystalline structure of Nb2O5 nanowires was confirmed by X-Ray diffraction (XRD). The optical property analysis of manufactured nanomaterials was performed on the basis of UV–Vis spectra of absorbance as a function of the wavelength. The energy gap and the optical constants were determined on the basis of recorded spectra. |
