Several millimeters long SiC–SiOx nanowires synthesized by carbon black and silica sol
Source abstract
Abstract
Abstract Several millimeters long SiC–SiOx nanowires with the diameters of 50–300 nm were successfully synthesized by carbothermal reduction using the raw materials of carbon black, silica sol and alumina at 1400 °C. The morphology and microstructure of nanowires have been studied in detail by X-ray diffraction (XRD), scanning electron microscopy (SEM), electron energy scattering (EDX), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). The nanowires were mainly in a straight wire-like morphology and consisted of 3C-SiC. Alumina played an important role in regulating the content of SiO2 in the reaction to produce SiO and keep nanowires subsequently growth along one-dimensional direction, and then an alumina-assisted growth of vapor–solid (VS) mechanism was proposed for the growth mechanism of several millimeters long SiC–SiOx nanowires.
