摘　　要：介绍了在开放和封闭两种状态下采用水热合成方法制备纳米结构Sb2Te3材料,并对不同反应温度、反应条件的样品进行测试分析,包括X射线衍射光谱法(XRD)、透射电子显微镜法(TEM)以及粒度分布等。实验结果表明,不同的合成工艺条件所获得产物均为Sb2Te3,但其反应进行的程度、尺寸大小以及形貌都不尽相同。获得的Sb2Te3纳米颗粒的直径最大不超过140nm。Sb2Te3 nano-powders were prepared by hydrothermal synthesis in closed and open systems respectively. The products were researched and analyzed by XRD, TEM and grain distributing. The analysis results show that, with different technical conditions, the degree of reaction, grain size, morphology are all dissimilar and the novel quasi-one-dimensional Sb2Te3 nanopowders with a maximum diameter of no more than 140nm are formed during the reactions.
