在非离子表面活性剂聚乙二醇(PEG)存在的条件下, 利用不同的钴盐分别与草酸进行低热固相化学反应, 一步合成了一系列金属配合物草酸钴纳米棒, 并采用XRD, TEM, SEM等分析手段对其结构和形貌进行了表征. 实验结果表明: 在合适的表面活性剂存在下, 利用钴盐与草酸的固相反应一步即可得到一维草酸钴纳米棒, 钴盐的不同及表面活性剂聚合度的不同均会影响纳米棒的形貌. 表面活性剂PEG在草酸钴纳米棒的形成过程中起到类似软模板的作用, 并诱导产物纳米晶沿某一方向定向生长从而生成纳米棒.

Metal complex cobalt oxalate nanorods were synthesized in one step by low-heating temperature solid-state chemical reactions of cobalt salts and oxalic acid in the presence of a nonionic surfactant, polyethylene glycol (PEG). The compositions and morphologies of samples were characterized by XRD, TEM and SEM. These results show that one-dimensional cobalt oxalate nanorods can be obtained in only one-step via the solid-state reactions of cobalt salts and oxalic acid with the assistance of a suitable surfactant. The morphologies of these nanorods were influenced by the different cobalt salts and surfactant with different degree of polymerization. The surfactant PEG plays a soft-template role in the process of rod-formation and induces the nanocrystallites of products to grow in definite direction. It is also expected that the present synthetic method can be extended to prepare other functional complex nanomaterials with desired morphologies by means of choosing suitable surfactant to modify the interface of solid-state chemical reaction.
