参考赵东元 Angew. Chem. Int. Ed. 2009, 48, 5875-5879. 实验步骤：Typically, FeCl3 (0.65 g, 4.0 mmol) and trisodium citrate (0.20 g, 0.68 mmol) were first dissolved in ethylene glycol (20 mL), afterward, NaAc (1.20 g) was added with stirring. The mixture was stirred vigorously for 30 min and then sealed in a Teflon-lined stainless-steel autoclave (50 mL capacity). The autoclave was heated at 200 °C and maintained for 10 h, and then allowed to cool to room temperature. The black products were washed with ethanol and deioned water for several times. 和另外一篇文献One-step synthesis of monodisperse, water-soluble ultra-small Fe3O4 nanoparticles for potential bio-application. Nanoscale 2013, 5, 2133-2141. 实验步骤：In a typical synthesis of 3.1 nm Fe3O4 nanoparticles, anhydrous FeCl3 (4 mmol) was first vigorously mixed with 40 mL of DEG to form a clear solution. Then, Na3Cit (1.6 mmol) was added and the mixture was heated at 80 C with stirring to form a clear solution. After dissolving anhydrous NaOAc (12.0 mmol) in the above solution, the mixture was transferred into a Teflon-lined stainless-steel autoclave (100 mL capacity) and sealed in air. Following this, the autoclave was kept at 200 C for 6 h. 制备水溶性Fe3O4，发现柠檬酸三纳在EG（乙二醇）或者DEG（二乙二醇）中很难溶解啊，无论是超声还是加热，都是一个个小晶体颗粒沉在容器底部，大家有做过的吗？都是怎么溶解比较好呢？非常感谢！ [ Last edited by sunshaokai on 2013-6-18 at 13:38 ] |
