摘要： 在表面活性剂聚乙二醇(PEG)存在下,利用Cd(Ac)2·2H2O,CdCl2·2.5H2O,3CdSO4·8H2O和CdCO3分别与NaOH在室温下进行固相化学反应,合成了一系列的Cd(OH)2纳米棒,并利用XRD,TEM和SEM对其结构和形貌进行了表征.实验结果表明,表面活性剂PEG在Cd(OH)2纳米棒的形成过程中充当软模板,对产物形貌的控制起到决定作用.利用这种表面活性剂辅助的软模板固相化学反应法合成一维纳米材料,具有简便易行、反应条件温和以及能耗低等优点.

Abstract: Cd(OH)2 nanorods were synthesized by solid-state chemical reactions of Cd(AC)2·2H2O, CdCl2·2.5H2O, 3CdSO4·8H2O, CdCO3 and NaOH at room temperature in the presence of a nonionic surfactant, polyethylene glycol 400(PEG-400). The compositions and morphologies of samples were characterized by XRD, TEM and SEM. The results show that surfactant plays a key role in the process of rod-formation and it can act as a soft-template. The method has some advantages, such as simple and facile technique, mild condition and low energy-consumption. It is also expected that the present synthetic method can be extended to prepare other special nanomaterials with desired morphologies by means of choosing suitable surfactant to modify the interface of solid-state chemical reaction.

Key words: Nanomaterials, Nanorods, Solid-state reaction, Cd(OH)2
