摘要: Zinc metal nanowires have been oxidized at temperatures of 200–500 °C in ambient air order to obtain ZnO nanowires. X-ray diffraction investigations reveal a complete transformation from Zn temperature ≥300 °C within 30 min. Temperature-induced grain growth attains saturation about 350 °C. Scanning electron microscopy studies show pronounced morphology change smooth, unidirectional rough, bursted nanorods >250 °C. The corresponding mechanism is discussed.
