目前較常用的制備方法多為水熱法(hydrothermal)和溶劑熱法(solvothermal)。這兩種方法的原材料易得(多為硝酸鈷(cobaltous nitrate ),硫酸鈷(Cobalt Sulfate ),醋酸鈷(Cobalt acetate)和氯化鈷(Cobaltous Chloride)的水合體)、方法簡單,且由于各種表面活性劑的加入,其形貌也是多種多樣。 采用溶劑熱技術(shù),以十二硫醇(Dodecanethiol)和PVP(Polyvinylpyrrolidone)雙組分表面活性劑為結(jié)構(gòu)導(dǎo)向劑,在乙二醇(ethylene glycol)和乙二胺(1,2-diaminoethane)混合溶劑中,成功制備出由絲帶狀納米片組成的微米Co六方片,且大量的六方片相互交叉連接成鏈?zhǔn)浇Y(jié)構(gòu),并采用SQUID法研究了它在室溫下的磁性質(zhì)。 |

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. |
