中文摘要：

以Bi（NO3）3和Te为反应物，在乙二胺四乙酸二钠（EDTA-2Na）、N，N-二甲基甲酰胺（DMF）与乙醇组成的混合溶剂以及过量强碱KOH的作用下，通过溶剂热反应，制得Bi2Te3热电材料的片式阵列纳米结构。利用XRD、SEM、EDX对产物的物相、形貌及成分进行了表征和研究。通过实验研究推断这种BizTe，片式阵列的形成过程可能是一个络合-成核-生长-脱离-组装的过程。

英文摘要：

Bi2Te3 nanomaterials with sheet-array structure were synthesized using solvothermal method in the presence of ethylenediaminetetraacetis acid disodium salt （EDTA）, ethanol and N, N-dimethylformamide（DMF）. The products were characterized by X-ray diffraction and scanning electron microscopy. The Bi2Te3 sheet-arrays in this solvothermal process were formed mainly by the following route as a coordination-nucleation-growth-disengagement-assembly process to result in such a novel nanostructure.
