关于孙守恒教授Au纳米颗粒制备的问题
|
||
|
本人在做孙守恒教授Au-Fe3O4纳米颗粒进行8nmAu颗粒制备时遇到问题,Au纳米颗粒无法通过离心机离出。 文献如下:1.0 g HAuCl4(H2O)3 (2.5 mmol) was added to 100 ml tetralin, followed by 10 ml oleylamine (30 mmol) to form a red solution. The solution was then heated at 65°C for 5 hrs and then cooled to room temperature. Ethanol was added to the solution, and gold particles were separated by centrifugation, washed by ethanol, and then redispersed in hexane. 其中,酒精加入四氢萘的量为体积比2:1 离心转速一万转,20min。 量等比例的减少,0.35g HAuCl4(H2O)3,35mL四氢萘,3.5ml油胺。 |
