摘要
分别以2种咪唑类室温离子液体为溶剂,通过简单的还原反应制备了碲(Te)一维纳米材料。利用X射线衍射(XRD)、透射电镜(TEM)和选区电子衍射(SAED)对样品进行了表征,并初步探讨了2种咪唑类室温离子液体对Te生长的影响。此外,实验中发现同时加入聚乙烯吡咯烷酮(PVP)和室温离子液体可以得到Te束状结构。
Te nanomaterials were prepared by using room temperature ionic liquids （ [ BMIM ] PF6 ） and （ [ BMIM ] BF4 ） as the solvent. The samples were characterized by X-ray diffraction （XRD）, transmitting electron micrograph （TEM） and selected area electron diffraction （SAED）. The effects of [BMIM]PF6 and [BMIM]BF4 on the growth of Te are discussed. In addition, Te with bundle-like shape were obtained using both PVP and [ BMIM] BF4.
