通过简单的表面活性剂辅助溶剂热法在 160°C 下 12 小时成功制备了平均直径和长度分别为 ∼50 nm 和 1 μm 的 Co3O4 纳米棒。 Co3O4纳米棒的形成归因于分散在乙醇中的钴离子在封端剂CTAB存在下的醇解。通过X射线衍射(XRD)对样品的组成和纯度进行了表征。透射和扫描电子显微镜图像显示颗粒是均匀的并且具有棒状形状。还讨论了Co3O4纳米棒的形成机理。
Co3O4nanorods with average diameter and length of ∼50 nm and 1 μm were successfully prepared via a simple surfactant-assisted solvothermal method at 160 °C for 12 h. The formation of Co3O4nanorods is attributed to alcoholysis of cobalt ions dispersed in ethanol in the presence of a capping agent—CTAB. The composition and purity of the sample were characterized by X-ray diffraction (XRD). Transmission and scanning electron microscopy images show that the particles are homogenous and have the shape of rods. The mechanism of forming Co3O4nanorods is also discussed.
