Abstract

Hollow SiO 2 nanowires (NWs) were one-pot fabricated via an electrospinning method. Their morphologies, structures, and chemical compositions were investigated by means of scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). In order to fabricate optimum hollow SiO 2 NWs, the relative volume ratio of tetraethyl orthosilicate (TEOS, an alkoxide precursor) to ethanol (solvent) was systematically controlled from 0.02 to 0.36. SEM, HRTEM, XRD, and XPS results indicate that amorphous SiO 2 hollow NWs can be one-pot synthesized by using the volume ratio of 0.18 under a constant voltage of 8.0 kV.
