[交流] 合成纳米NiO

请问采用什么方法可以成10nm左右的NiO?有做过的请多多指教。

文献题目:Size- and Shape-Controlled Magnetic (Cr, Mn, Fe, Co, Ni)
Oxide Nanocrystals via a Simple and General Approach
杂志:chem mater 2004 16 3931-3935
摘要:A general, reproducible, and simple strategy using generic chemicals is introduced for controlling the size, shape, and size distribution of oxide nanocrystals. The reaction system was generally composed of the metal fatty acid salts, the corresponding fatty acids, and a hydrocarbon solvent. The method is based on the pyrolysis of metal fatty acid salts, the most common metal compounds compatible with nonaqueous solutions. Synthesis of nearly monodisperse Fe3O4 nanocrystals in a large size range (3-50 nm) was developed as the model system. The method was further applied for the growth of oxide nanocrystals of the other magnetic metals in the fourth rowsCr2O3, MnO, Co3O4, and NiO nanocrystals. The size and shape control of the nanocrystals were achieved by varying the reactivity and concentration of the precursors. The reactivity was tuned by changing the chain length and concentration of the ligands, the fatty acids. Alcohols or primary amines could be used as the activation reagents when a given metal fatty acid salt was not sufficiently active under selected reaction conditions.
讲的很详细,可以参考一下。
