| 摘 要： | Silicon nanowires were synthesized from nanometer silicon dioxide powder under potentiostatic electrolysis at -1.20 V (vs Pt reference) for 4 h in molten CaCl2 at 900 ℃. The morphology, structure and chemical composition of the samples prepared by electroreduction method were characterized by field-emission scanning electron microscopy(FE-SEM), High-resolution transmission electron microscopy(HRTEM) coupled with electron energy dispersive spectroscopy(EDS), laser Raman and X-ray diffraction(XRD). The results revealed that silicon nanowires were crystalline with a diamond cubic structure, the diameter was distributed from 50 nm to 80 nm and the length was generally several micrometers. The formed nanowires basically consisted of silicon monocrystalline and amorphous oxide sheath.
