目前较常用的制备方法多为水热法（hydrothermal）和溶剂热法(solvothermal)。这两种方法的原材料易得（多为硝酸钴(cobaltous nitrate )，硫酸钴(Cobalt Sulfate )，醋酸钴(Cobalt acetate)和氯化钴(Cobaltous Chloride)的水合体）、方法简单，且由于各种表面活性剂的加入，其形貌也是多种多样。 采用溶剂热技术，以十二硫醇(Dodecanethiol)和PVP(Polyvinylpyrrolidone)双组分表面活性剂为结构导向剂，在乙二醇(ethylene glycol)和乙二胺(1,2-diaminoethane)混合溶剂中，成功制备出由丝带状纳米片组成的微米Co六方片，且大量的六方片相互交叉连接成链式结构，并采用SQUID法研究了它在室温下的磁性质。 |

At present, the rather mostly used methods are hydrothermal and solvothermal.These two methods are quite simple and their raw materials can be easily obtained (mainly cobaltous nitrate Cobalt Sulfate Cobalt acetate Cobaltous Chloride hydrosyncronization). Besides, the addition of various surfactants makes it diverse in morphology. Solvothermal,with bi-component surfactants, dodecanethiol and PVP (Polyvinylpyrrolidone), as structure-directing agents,has been adaopted, in the mixed solvents of ethylene glycol and 1,2-diaminoethane, and we have successfully developed a six-piece micrometer Co composed of ribbon-like nanoplates, most of which overlapped to one another and linked up as a chain structure. Meanwhile, the magnetic properties of the six-piece micrometer Co have also been studied under the methodology of SQUID. |
