Abstract
The aim of the study was the production of ceramic SiO2 nanowires using the sol-gel and electrospinning methods from solution of PVP/TEOS/AcOH/EtOH. The obtained fibrous mats was subjected to preliminary drying at room temperature and next was subjected the calcination process in air to obtain pure amorphous silicon dioxide nanowires. Analysis of the morphology and chemical composition of the resulting nanowires was carried out using a scanning electron microscope (SEM) with energy dispersive spectrometer (EDS). In order to analyze the structure of the obtained materials were used high-resolution transmission electron microscope (TEM) and X-ray diffraction analysis (XRD). The analysis of the optical properties and the energy band gap of prepared nanowires was determined by spectral analysis of the absorbance in the function of the energy of radiation obtained using a UV-Vis spectrophotometer
