在表面活性剂存在下，通过简便的水热还原方法制备了均匀的 Co 球形组件，产率为 98%。组装的纳米结构由厚度约为 20 nm 的有序纳米片组成，通过扫描电子显微镜 (SEM)、透射电子显微镜 (TEM) 和高分辨率 TEM (HRTEM) 进行表征。这种材料表现出铁磁特性并具有高表面积，显示出在催化剂和其他相关纳米器件中的潜在应用。
Uniform Co spherical assemblies were prepared via a facile hydrothermal reduction approach in the presence of surfatctants with a yield of 98%. The assembled nanostructures were composed of ordered nanoplatelets with a thickness of similar to 20 nm, as characterized by scanning electronic microscopy (SEM), transmission electronic microscopy (TEM), and high-resolution TEM (HRTEM). This material exhibits ferromagnetic characteristics and has a high surface area, showing potential applications for catalysts and other related nanodevices.
