Metallic tin nanorods were synthesized by a sonochemical method employing the polyol process. In the reaction a solution of SnCl2 in ethylene glycol was exposed to high-intense ultrasound irradiation. The phase and elemental compositions, and thermal properties of the as-synthesized samples were characterized by XRD, EDX, SAED, XPS, DSC, TGA, and BET measurements. The morphologies of the products were further characterized with SEM, TEM, and HRTEM. The results show that crystallized metallic tin nanorods in diameters of 50-100 nm and in lengths of up to 3 microm were synthesized. The nanorods are encapsulated in a thin layer containing Ti and carbon compounds. On the basis of the obtained data, a possible mechanism of the formation of tin nanorods was proposed.
采用多元醇法通过声化学方法合成了金属锡纳米棒。在该反应中,将SnCl₂在乙二醇中的溶液暴露于高强度超声辐射下。通过XRD、EDX、SAED、XPS、DSC、TGA和BET测量对合成样品的相组成、元素组成和热性能进行了表征。用SEM、TEM和HRTEM进一步表征了产物的形貌。结果表明,合成了直径为50-100nm、长度可达3微米的结晶金属锡纳米棒。纳米棒被包裹在一层含有钛和碳化合物的薄层中。根据获得的数据,提出了锡纳米棒形成的可能机制。
