摘　　要：用水热合成法制备了纤锌矿结构的超细金属Zn纳米线，X射线衍射结果分析表明所制备的金属Zn纳米线是单一的纤锌矿结构。扫描电子显微镜照片显示合成的纳米线长度达几微米，直径10～20nto，每一根纳米线都有一个锥形的顶部。进一步研究表明反应温度对合成产物的形貌有重要的影响，最后对纳米线的生长机制进行了初步分析。Ultrathin zinc element nanowires have been synthesized by etchng zinc foil at 130℃ by hydrothermal method. XRD result indicated as-synthesized Zn nanowires possess wurtzite structure. SEM images showed Zn nanowires have the length of micrometer grade and the diameter of 10-20nm,and each nanowire owns a tapered top. The influences of reaction temperature on the nanowire formation were investigated. It was found that higher temperature led to the formation of nanowires. Growth mechanism of Zn nanowires was proposed temporarily.
