  • 利用简单的化学气相沉积法,以Sn粉为源材料合成不同形貌的一维SnO2纳米棒、纳米线和纳米花等纳米结构,并通过减小载气中的氧含量获得新颖的SnO2亚微米环状结构.通过调节Sn粉的量和载气中的氧含量、升温速率等试验条件,有效实现SnO2一维纳米结构的控制生长.采用扫描电子显微镜、能谱仪和X射线衍射仪表征产物形貌、成分和物相结构,并探讨了SnO2微纳米材料的生长机理.
    Using Sn powders as source material, different SnO2 nanostructures, such as nanowires and nanorods, nanoflowers were synthesized successfully by simple chemical vapor deposition in a low temperature. SnO2 submicron rings were obtained by reducing the oxygen gas concentration in carrier gas and the effect of oxygen gas on controlling the morphology of products was demonstrated by adjusting the quantity of Sn powders and the rate of heating. The products were characterized by X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray spectrometry. The growth mechanism of the products was further discussed.
