氧化镁纳米棒的制备与表征
Preparation and Characterization of Magnesium Oxide Nanorods
【摘要】 以六水氯化镁和轻质氧化镁为原料,制备出碱式氯化镁纳米棒;再以碱式氯化镁纳米棒为前驱物,采用沉淀转化法制备出前驱物氢氧化镁纳米棒;再通过前驱物热分解法得到直径150~250 nm,长6~10μm的氧化镁单晶纳米棒。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和选区电子衍射(SAED)对产物进行表征与分析,研究了煅烧条件对氧化镁纳米棒形貌的影响,得到了氧化镁纳米棒的最佳制备工艺条件为:煅烧温度400℃,煅烧时间1 h,升温速率3℃/min。
【Abstract】 Magnesium chloride nanorods are prepared by liquid phase method with light magnesium oxide and magnesium chloride hexahydrate as raw materials.Then,using converting precipitation method,magnesium hydroxide nanorods are synthesized with basic magnesium chloride nanorods as precursor.Magnesium oxide single crystal nanorods which diameter of 150~250 nm and length of 6~10 μm are prepared,after calcining the magnesium hydroxide nanorods.The obtained products are characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM) and selected-area electron diffraction(SAED).Effects of preparation parameters on the morphology of magnesium oxide nanorods are investigated systematically.The result shows that the optimum conditions to prepare magnesium oxide nanorods are as follows:calcination temperature of 400 ℃,calcination time of 1 h,heating rate of 3 ℃/min.
