摘要 以水为反应介质,NaBH4为还原剂,合成了BizTe3纳米管及纳米微粒。溶液首先在超声波发生器中预处理1h,然后置于150℃,水热反应釜中继续反应48h。XRD分析表明:合成产物主要物相为Bi2Te3;SEM观察可见产物中有纳米管生成,纳米管直径约为50-100nm,管壁厚约8-10nm,长度在500nm以上。EDS分析表明:纳米管成份为Bi2Te3。Bi2Te3纳米管可能的生长机制为纳米薄片-卷曲-闭合-纳米管。 The Bi2Te3 tubes were obtained via a ultrasonic assisted hydrothermal reaction in the presence of ethylenedia- minetetrancetic acid disodium salt (EDTA). The products were charactrized by cold field emission scanning electric microscope (FESEM) and energy diffraction spectrometer (EDS) respectively. A possible formation mechanism is proposed.
