摘要/Abstract

摘要：

以CeCl₆•6H₂O 和NH₃•6H₂O为原料, 使用离子液体1-丁基-3甲基咪唑氯盐([Bmim]Cl)辅助水热法在160℃下合成了CeO₂纳米棒。采用X射线衍射(XRD)和高分辨透射电子显微镜(HRTEM)对样品的结构和形貌进行了表征。实验结果表明: 使用离子液体辅助水热法制备的产物为CeO₂纳米棒, 而没有离子液体时产物则为外形无规则的纳米颗粒。所制备的纳米棒直径为13~25 nm, 长度为200~500 nm。增大离子液体的用量将得到纳米颗粒。此外, 升高水热温度至180℃所得样品为直径19~24 nm的纳米球, 该纳米球由2 nm 的纳米晶团聚而成。

Abstract:

CeO₂ nanorods were synthesized by a hydrothermal method at 160℃ from CeCl₆·6H₂O and NH₃·H₂O in the presence of an ionic liquid 1-butyl-3-methyl-imidazolium chloride ([Bmim]Cl). The phase and morphology of the resulting products were characterized by X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM), respectively. The results reveal that morphology of CeO₂ prepared in the presence of the ionic liquid is nanorod while it changes to irregular nanoparticle without ionic liquid. The resulting nanorods are about 13-25 nm in diameter and 200-500 nm in length. With the increase of ionic concentration, nanorods were disappeared gradually and nanoparticles were obtained. Moreover, increasing the hydrothermal temperature to 180℃, nanospheres at size of 19-24 nm could be synthesized by aggregation of ~2 nm nanocrystals.
