一种六角形纳米板块Sb2Te3的制备方法
摘要：
本发明涉及一种六角形纳米板块Sb2Te3热电材料的制备方法。目前的制备方法存在着重复性差、成本高等问题。本发明具体方法是：将碲粉和锑的可溶性盐加入聚四氟乙烯罐中，加入还原剂，再加入乙二胺水溶液至聚四氟乙烯罐容积的70%～90%，将聚四氟乙烯罐加盖后置于不锈钢高压釜中密闭，再将不锈钢高压釜置于烘箱中反应；反应釜自然冷却至常温，将反应液过滤，得到纳米粉体，然后分别用乙醇和蒸馏水洗涤后干燥，获六角形纳米板块Sb2Te3。本发明方法采用乙二胺作为晶体形状调控试剂，无需表面活性剂或贵重原料，具有操作简单、重复性好、成本低的特点。
摘要（英）：

The present invention provides a producing method of hexagonal nanometer plate Sb2Te3 thermoelectric material. The present producing method has poor repetitiveness, high cost. The specific method of the invention is: adding Tellurium powder and stibonium soluble salt to polyfluortetraethylene tank, adding reducer, further adding quadrol aqueous solution to tank which polyfluortetraethylene volumeis 70-90%, placing polyfluortetraethylene to stainless steel high-pressure autoclave seal after lidding of polyfluortetraethylene, the stainless steel high-pressure autoclave futher is placed in the oven; when reaction kettle is cooled to the normal temperature, nanometer powder is obtained by filtering reactive liquid, hexagonal nanometer plate is obtained by washing using ethanol and distilled water, and drying. The invention adopts quadrol as crystal shape regulating reagent, does not need surface active agent or precious material, has simple operation, better repetitiveness and lower cost.
